As you probably remember, along with the processors Ryzen second generation (Pinnacle Ridge), AMD introduced a new chipset X470, thereby enabling motherboard manufacturers to bring to market an updated flagship Socket AM4 platform. And this really makes sense: the design boards on the previous chipset for the older Ryzen, X370, often left much to be desired. Most of these products were designed prior to the release of the first processor microarchitecture Zen, and at that time few believed that the new solution from AMD will be so good that I can seriously compete with intelocking CPU. This had an impact on the approach to the design: even among platforms based on the older Socket AM4-chipset X370 many of them contain certain compromises that are not too feature-rich and does not seem to be the flagship platforms.

X470 should solve the issue. That is capable of AMD Ryzen, it is now understood very well, so motherboard manufacturers can, without fear, to create a fancy and expensive platform. That the demand for them will, no doubt. This wave appeared a lot of new solutions, and almost all of such charges compared to their predecessors, used chipset X370, do differ markedly improved characteristics.

However, the very core of this transformation of the flagship boards in the new chipset X470 did almost nothing. If we compare the characteristics of the chipsets X470 and X370, it appears that support PCI Express, SATA, and USB ports, they are absolutely identical.

  Acceleration XFR2 /PB2 GPU USB 3.1 Gen2 USB 3.0 USB 2.0 PCIe 3.0 PCIe 2.0 SATA RAID StoreMI
X470 Yes Yes x8/x8 2 6 6 0 8 8 Yes Yes

B350 Yes No x16 2 2 6 0 6 6 Yes No
A320 No No x16 1 2 6 0 4 6 Yes No

* Support XFRPrecision 2 and Boost 2 is added to c with BIOS updates

In fact, the only significant hardware change X470 compared to the predecessor was the reduction of energy consumption from 6.8 to 4.8 W at full load. Curiously, this has been achieved without any modification of process technology: a new X470 is made at TSMC on the same 55-nm technology as the X370. Helped exclusively the redesign of the power infrastructure of the chip.

Two small innovations were added to the software level. First, X470 appeared StoreMI technology that allows you to compile in a single volume high-speed SSD (any type) and bulk HDD, a single hybrid data warehouse with high speed and capacity. Second, characteristic for processors Ryzen two thousandth series technologies Precision Boost 2, XFR2, according to official information, originally only work in motherboards based on the new chipset.

All these innovations can hardly be called fundamental. The decrease in heat dissipation of the chipset on a few watts in a desktop PC will generally imperceptible; StoreMI – only malofontannaya function; and support for Precision Boost 2, XFR2 is important only where the CPU is running without overclocking, and even then, the performance gains provided by these technologies, not too noticeable. In addition, in recent versions of firmware support for these technologies appeared in motherboards based on chipset X370. And this means that the difference in fees on the basis of the X470 and X370 is for the most part only the result of experience, and the changed attitude to the platform on the part of engineers.

In this article we will focus on the new X470-Board top-level company ASUS – Crosshair VII Hero (WiFi/ac), which just serves to illustrate the above. At first glance, it is almost the same as the last Board Crosshair VI Hero on the basis of the X370, but more detailed acquaintance emerge differences, minor that does not name.

A new Board has better power subsystem, which is now involved not 10, and 12 phases. In addition to fees added asynchronous mode overclocking the base clock generator, allowing to supply to processor cores, DRAM Infinity Fabric and different values of the BCLK frequency. Changes were made in the monitoring of voltages, which now became more accurate. A number of innovations is in the UEFI BIOS. For example, ASUS engineers have implemented new technology-based Precision Boost the acceleration system Performance Enhancer and also could make for Crosshair VII Hero Stealth mode completely turns off all illumination.

In other words, the scale (and not) changes sufficiently, and in order to get familiar with them, we did this review.

Motherboard ASUS Crosshair VII Hero represented on store shelves in two versions – with built-in Wi-Fi-controller and without it. Version WiFi/ac has a recommended price of $300, and the version without wireless support is $20 cheaper. While a similar fee on the basis of chipset X370, Crosshair VI Hero, is now sold a cheaper new for $40. From this we can conclude that the transition to a X470, indeed, involve some appreciation of the platform Socket AM4.

#Packaging equipment

As befits a luxury product series Republic of Gamers, the new ASUS ROG Crosshair VI Hero comes in at the same time bright and simply decorated box. The front side of the box contains only the name of the series, model and a brief enumeration of supported technologies in the form of large icons.

On the back of the box provides detailed Board specifications, private labels marked its merits, and lists the inputs and outputs on the interface panel. On the sticker from one side of the box you can find the serial number and a short list of characteristics.

Inside the main package are inserted two flat boxes, one of which bears the fee, additionally covered with a plastic lid with clamps, and other parts and accessories.

Along with the cost supplied four SATA cables with latches, two screw fastening the M. 2 modules, hard connective HB-bridge for SLI, the connector for connecting the cables of the system case unit Q-Connector, two extension cable to tapes, external lighting and Wi-Fi dual-band 2T2R antenna.

Also included in the kit instruction manual and DVD with drivers and utilities, and as a bonus there is a whole array of stickers of different types and purposes.

Fee is manufactured in China, and it is a three-year warranty. Allotted for the test instance ASUS ROG Crosshair VII Hero (WiFi/ac) refers to version 1.02. In Russia this model can be purchased for the price of 20 thousand rubles.

#Design and features

The ROG series is developed by ASUS since 2006, and throughout this time, the producer pays great attention to how its constituent motherboard look like. In Crosshair ROG VII Hero (WiFi/ac) evolution came down to the fact that the Board has acquired the most “dark” design: PCB slots, heat sinks, casing in the back – everything is black, which interrupt only the gray labels on the PCB and the decorative stripes on the radiators. Develops dark skin and a new mode of operation decorative lighting – Stealth Mode, in which the Board owner can turn off all the glowing elements: not only RGB illumination, but also numerous diagnostic or informational led.

Fans of the unicorns, by contrast, is addressed to the backlit RGB-insert in a protective casing back of the card, and the glowing ROG logo in the chipset. In addition to this Crosshair VII Hero (WiFi/ac) allows you to connect four RGB strips: two regular and two addressable. Algorithms of all this illumination, as usual, are configured through specialized software ASUS Aura.

Crosshair ROG VII Hero (WiFi/ac) has a standard form factor ATX size 305 × 244 mm. I Must say that this Board is just Packed with various components. The possibilities are very rich, and for their implementation of only one chip AMD X470 and on-chip SoC is not enough, so ASUS engineers had to resort to using a large number of additional controllers. However, the typical format they come out, and moreover, the surroundings of the CPU socket on the motherboard was quite a lot of space, making Crosshair ROG VII Hero (WiFi/ac) is convenient in practical use in a traditional enclosure and the stand.

The reverse side of the Board for the most part free of any elements. She made only some of the control components of the power circuit of the processor.

The fact that the charge is among the flagship products for overclockers and gamers, clearly visible on the vehicle its rear panel. In addition to the usual things on it there are two buttons to reset the settings of UEFI BIOS and forced flashing, and even such Exotica as the PS/2 port to connect a mouse or keyboard. In addition, there are two Wi-Fi antenna output, two USB 2.0 ports, eight USB 3.0 ports, one USB port 3.1 Gen2 performance of Type-A and Type-C plug socket for connection Gigabit network, S/PDIF output and a set of five gold plated analog audio jacks. The rear panel ROG Crosshair VII Hero (WiFi/ac) supplied from the preset panel I/O Shield, which significantly simplifies the system Assembly in the housing.

Please note: under consideration Board has no display outputs. This means that even when the Raven Ridge processors with integrated graphics, it will take a discrete graphics card.

One of the main differences ASUS ROG Crosshair VII Hero (WiFi/ac) from its predecessor (Crosshair VI Hero) concerns the allocation of lines PCI Express slots. On the new Board has three PCIe x16 slots where the first pair is controlled by a processor and can run at x16/x0 or x8/x8 while the third slot refers to the chipset. So he could only offer mode PCI Express 2.0 x4, and mechanical boost SafeSlots to effectively withstand the loads encountered during installation of heavy graphics cards with only the first two PCIe x16 slots.

Also the Board has two M. 2 connectors, which claimed to support PCI Express 3.0 x4 drives. Both these slots are to the CPU, but differ in their implementation. Slot, rests against the processor, and an indoor brand of radiator, divides the line graphic bus. So installing it on the drive causes the CPU PCIe x16 slots and forced into the as x8/x4.

No effect on the throughput of the graphical interface only the M. 2 slot is located at the bottom of the Board. And by the way, except he NVMe drives, and supports SATA SSD.

However, this “full” connector – open, it does not feature the brand Ossowski radiator.

The storage media can be connected to the SATA ports, which are under consideration, the Board has six pieces. Thus, in the organization of the disk subsystem Crosshair ROG VII Hero differs markedly from the preceding fee: added a second M. 2 slot, but the number of SATA ports decreased by two.

Even a cursory acquaintance with the ASUS Crosshair ROG VII Hero (WiFi/ac) evident that it scattered atypical large number of connectors for connection of fans – as many as eight. Like Arsenal – a rarity, but also, the Board has developed control devices that are connected to these connectors, and supports adjustable speed via PWM, and the old voltage. In addition, two of the fan connectors support increased to 3 A current, and two are for pumps of liquid cooling systems and, by default, always work in full-speed mode. A pair of connectors for fans the CPU cooler uses the combined control.

In addition, ASUS did not forget to add the cost of a traditional connector for daughter card FAN Extension, which allows you to extend the array of connected fans. However, the card itself at this time, in the not supplied. To the motherboard you can connect an additional temperature sensor. Incidentally, it is quite possible to place on the abdomen of the processor: in order to be able to stretch the cable with a thermocouple inside the socket there is a hole.

In the upper right corner of the Board near the 24-pin power connector, arranged a kind of “control center”. Put back the Start button and the Reset indicator POST-code LEDs Q-LED showing the initialization process of the Board, as well as checkpoints to check key voltages with a multimeter.

Radom are connectors for led strips (addressable and conventional), as well as USB 3.1 Gen2 for connection of the respective body of the port.

The other half of the connectors and control elements on the circuit Board attributed to its lower bound. There are connectors for connection of sensors of flow and temperature liquid cooling system, additional connector for thermocouples, a couple of connectors for incorporation of led strips and connectors USB 2.0 ports and USB 3.0. There is also the ROG Extension connector, mode switches for extreme overclocking Slow Mode and LN2, and is also useful for overclocking experiments buttons Safe Boot and Retry.

All radiators available on the ROG Crosshair VII Hero (WiFi/ac), mounted on the screws and adjacent to the cooling components via elastic thermal pads.

An exception only one radiator for the M. 2 drive. He is used as a thermal interface thermally conductive double-sided adhesive tape, the manufacturer, before using need to put in “combat state”.

For the detailed circuitry underlying the Crosshair ROG VII Hero (WiFi/ac) boards have been removed all the radiators and decorative casing covering the rear face.

First and foremost interest is the power of the processor. The fact that ROG Crosshair VII Hero (WiFi ac) ASUS engineers have changed its design. Supply CPU phases became 2 more and also changed their location on the Board.

This significantly improved temperature control: the power components in the Converter power now warmed up 10-15 degrees less when compared with the cost on the basis of the X370, Crosshair ROG VI Hero.

Along with this, ASUS engineers have improved the VRM and the radiator – it’s not just two aluminum bars, connected heat pipe, and sticks with fins.

VRM in the new Board is assembled on the principle of 10+2 (VCORE + VSoC) on the basis of the PWM controller (EPU) ASP1405I which apparently is parameterone IR35201.

This means that the real phases for the CPU power five, but they are doubled when using doublers IR3599 mounted on the reverse side of the Board. Each phase uses 60-amp integrated circuit IR3555M PowlRstage and an inductor Micro-Fine Alloy.

It should be noted that this time ASUS has come up with an interesting solution – two phase power SoC split an array of ten phases of the Vcore in space into two groups – this allows you to improve the sink. Given the high power VRM to power the processor, the Board provides two 12-volt connector: standard 8-pin and additional 4 pin. Additional connector may be required in experiments on extreme overclocking.

The power supply circuit of the memory subsystem are collected in a two-phase system generated by the PWM controller ASP1103 with integrated drivers and field effect transistors ON Semiconductor.

Interesting on the ROG Crosshair VII Hero (WiFi/ac) there is external clock generator ICS 9VRS4883BKLF. Its presence means that the Board allows you to overclock the CPU not only multipliers, but also through the increase in BCLK frequency.

External clock generator is found on the flagship Socket AM4-boards quite often. But the solution is a feature of the ASUS: ROG Crosshair VII Hero (WiFi/ac) supports the new asynchronous mode in which the increased carrier frequency is applied to only the processor core and the Infinity Fabric, the memory controller and the PCIe bus remain on a standard 100 MHz.

The audio path in Crosshair ROG VII Hero (WiFi/ac) based on codec Realtek ALC1220. Also in the circuit is the DAC ESS Sabre ES9023P and amplifier Texas Instruments RC4580I. To reduce noise in analog part is separated from the other components of the non-conductive area on the circuit Board, and in addition, the manufacturer has not stinted on the special audiophile grade electrolytic capacitors Nichicon Gold series. As before, asososca sound scheme has special protection from the loud clicks of the speakers when turning on and off, and headphones that are able to “pump” the audio outputs of the Board, can have a resistance of 600 Ohms.

Wired Gigabit network is represented on a given Board, with Intel i211T, complemented by brand protection against electrical discharges LANGuard.

Wireless network Wi-Fi 802.11 ac 2 × 2 2.4/5GHz MU-MIMO is implemented as a separate module for Realtek RTL8822BE established in located in the area of the rear panel a special M. 2 slot type E.

Exactly what is provided by the simultaneous existence of Crosshair ROG VII Hero with either wireless networking support, and without Plata can be equipped with this module, and can be supplied without it.

Ports USB 3.1 Gen2, derived on the rear panel of the Board, working through an additional controller ASMedia ASM3142, which is reinforced by the switch ASMedia ASM1543 for the implementation of the port Type-C. the same Chipset USB ports 3.1 Gen2 announced at VII Hero ROG Crosshair to the inner connector, which is equipped with redriver Pericom PI3EQX, allowing you to connect it directly to the connectors of Type-C.

For the realization of the basic functions of I / o, including PS/2 ports, meets chip ITE IT8665E. Expand monitoring and fan control brand essovskie controllers ROG and TPU. But for a more accurate determination of voltages supplied to the CPU, the motherboard appeared differential operational amplifier AS324M-E1. This enhancement Crosshair ROG VII Hero can boast of a more accurate monitoring of voltages than most other boards, including authorship of the same ASUS.

To control the led backlight ASUS developers have implemented the whole scheme including the signature and AURA chip microcontroller ST Micro STM32F.

Getting acquainted with the ROG Crosshair VII Hero (WiFi/ac), we met another interesting detail: the BIOS chip on this Board has a capacity of 256 MB, while on other boards for Socket AM4 processors used twice less capacious chips ROM.

Nevertheless, the very ASUS says that now she only uses half of the available volume, and the second half is for the future, in case when the output of the promising processors, AMD wants to increase the size of the BIOS.

Not sure that regular readers 3DNews frequently visit websites of a motherboard manufacturer. But I sort of activity have to do it very often. Getting into the hands of Z390 GIGABYTE AORUS PRO, I immediately examined the characteristics of the product on the official website of the Taiwanese company. And what do we see? The first thing to GIGABYTE I draw your attention is the presence of a 13-phase power subsystem. I remember before the manufacturers first advertised chips such as the RGB backlight, cool built-in audio section and the presence of certain modern connectors. Well, comrades-zhelezyachniki, after the release of 8-core processors Coffee Lake Refresh the situation has changed radically. That is why it was decided to test Z390 GIGABYTE AORUS PRO with four from Intel and see how the power Converter can handle overclocking Core i9-9900K up to 5 GHz. But first, let’s take a closer look at the cost.

GIGABYTE Z390 AORUS PRO

Z390 GIGABYTE AORUS PRO

#Specifications and packaging

I note that you will meet two versions of PRO-motherboard GIGABYTE. I consider “simple” modification, devoid of the wireless communication module. Recall that the set of logic Z390 hardware Express supports the standards 802.11 ac and Bluetooth. Model Z390 GIGABYTE AORUS PRO WIFI is an average of 1,000 more. So if you don’t want to mess with a wired Internet connection, you can pay attention to this version of “Proshka”. In the rest of the Board came out of the same. Main technical specifications GIGABYTE AORUS PRO Z390 is given in the table below.

The motherboard is Packed in a large and colorful cardboard box. In addition to the Board, it was a lot of accessories, both useful and not:

  • user manual, sticker with the logo of AORUS and other labels for wires, and a CD with software and drivers;
  • four SATA cable;
  • extension cable to connect the RGB strip;
  • two thermocouples;
  • additional screws for securing the SSD;
  • set ASUS q-connectors;
  • HB SLI-bridge to connect two graphics cards NVIDIA GeForce.

#Design and capabilities

So, Z390 GIGABYTE AORUS PRO — Board form factor ATX. Because in front of us is not a budget device, it uses the undiminished circuit Board with sides 305 and 244 mm. Regular readers know that I do not like truncated ATX: manufacturer of such devices “cuts” a part of the PCB, and in the end when installing Board in the computer chassis part PCB slack — in this condition, you must carefully connect the memory modules and 24-pin power supply connector not to break the PCB.

The picture above clearly shows that to the layout of components Z390 GIGABYTE AORUS PRO is though not serious, but still claim. But let’s order.

To the layout of expansion slots, no complaints. Closest to the CPU socket is a connector PCI Express x1, and followed by a PCI Express x16 slot — the main PEG port, which in 99% of cases will be installed graphics card. Such a layout I think is perfect as it allows you to set up on the CPU any cooler. For example, GIGABYTE AORUS PRO Z390 on friendly terms with such “monsters” like the Noctua NH-D15 and its Archon X2. If you plan to use the video card, the cooling system which occupies only two slots, you will lose nigersan slot PCI Express x1. At the same time, more importantly, retained access to both M. 2 sockets — manufacturer additionally equipped with aluminum cooling systems. If you plan to use two graphics adapters, you will lose one PCI Express x1. Paired arrays AMD Crossfire and NVIDIA SLI work under the scheme x8+x8. The third PCI Express x16 uses only four lines. All the expansion slots conform to PCI Express 3.0.

I note that both PEG port is reinforced, and all three PCI Express x16 slots are double locking and additional soldering points. In total, according to the manufacturer, these design solutions strengthen connectors 1.7 times when the load on the fracture, and 3.2 times when the load on the pulling.

Reinforced at the Board and the DIMM slots.

The undoubted advantage of Z390 GIGABYTE AORUS PRO is the presence of eight 4-pin connectors for fans connection. It supports even the fans power up to 24 watts. Using the technology Smart Fan 5 can be controlled by impeller with shim and without it (that is, fans with 3-pin connectors). Connectors SYS_FAN5_PUMP and SYS_FAN6_PUMP, soldered next to the DIMM slots intended for connection of the pump liquid cooling system. If the system will be used maintenance-free “dropsy”, then this arrangement can be considered a failure — the cable from the waterblock would have to pull across the memory modules, and it’s ugly. I would place the GIGABYTE one PUMP connector would set as close to the CPU socket. If you build a PC custom DLC, you can connect a pump with reservoir that will be fixed, e.g., on the bottom of the housing towers will be convenient. Only in the case of very large Cabinet form factor Full Tower, make sure that the length of the wires coming from the pump will be enough.

To the SYS_FAN1 connector, located next to the power connector of the CPU, risen is not very easy — especially if you have already installed the cooler on the CPU. On the other hand, it is clear that positioning this connector in a different place would prevent the M. 2 slot.

Z390 GIGABYTE AORUS PRO has two M. 2 ports, equipped with aluminum radiators. The manufacturer claims that the cooling system Thermal Guard effectively dissipates heat, helping to eliminate the cause of the throttle with respect to M. 2 devices, but the specific data unfortunately, the product description is not given. There is only an abstract graph. Top connector allows you to install SSD formats 2242/2260/2280/22110, supports SATA 6 Gbps and PCI Express 3.0 x4. The lower M. 2 slot supports installing the SSD 2242/2260/2280 formats, it also summed up the four lines PCI Express 3.0, and it can also operate in SATA mode.

Also on the motherboard has six SATA connectors 6 GB/s.

When assembling the system unit consider the fact that when using the M. 2 port will be disabled some SATA connectors, as they divide throughput PCI-E with each other. All possible combinations when connecting the drive displayed in the table above.

Among the internal connectors note the presence of USB 3.1 Gen2. In my opinion, the port and internal USB 3.1 Gen1 soldered in the wrong places: they are removed from the edge of the circuit Board with a built — in protruding wires again will look not very pretty.

In the bottom of the Board there are pads for connecting the front panel audio connector, 12 – and 5-volt RGB strip, TPM module, S/PDIF and two USB 2.0. In the upper part of PCB, next to the DIMM slots, show up more blocks to connect the 12 – and 5-volt RGB strips. As you can see, no backlight in 2018 — will. All connected to the motherboard of the tape and fans are configured in one application called RGB Fusion.

As for the backlight directly on the Board itself, the LEDs supplied with the inscription and the AORUS logo on the chipset, the audio path and the DIMM slots. Backlight Z390 GIGABYTE AORUS PRO supports 16.8 million colors and 11 modes.

Among the external connectors deduced on panel I / o, note the presence of three ports USB 3.1 Gen1: two A-type and one C-type. From the video outputs on the I/O panel has HDMI only, which, in my opinion, enough for those who will use the built-in Intel graphics. The rest of GIGABYTE AORUS PRO Z390 there is a fairly typical set of interfaces.

It should be noted that the plug on the I/O panel is already built into the motherboard. Personally, I think this design decision the undoubted advantage of the device in question.

A test Board equipped with high-quality Gigabit network controller Intel I219-V and sound chip Realtek ALC1220-VB. The audio codec has a ratio of “signal to noise” of 120 dB and an intelligent amplifier that automatically determines the impedance of the connected headphones. Separately, the manufacturer notes that the new controller enables us to convey to the Network the voice with a microphone connected to the 3.5 mm Jack on the front or on the rear panel. In addition, the tract is equipped with special capacitors WIMA FKP2.

 

So we got to the main element Z390 GIGABYTE AORUS PRO — power processor and other components. Please note that for CPU power, in addition to the existing 8-pin connector, there is provided another 4-pin connector. I note that not all power supplies are equipped with additional wires. At the same time, my experience is that overclocking Core i9-9900K at home is enough one such connector in 8 pins. All the power connectors of the motherboard are strengthened — increased contact area when connecting the cables of the power supply.

So, GIGABYTE claim that the power Converter Z390 AORUS PRO consists of 13 phases, 12 of which are unique to the CPU. Also on the official website of the manufacturer claims that the GIGABYTE AORUS PRO Z390 designed for overclocking all cores 8-core Coffee Lake Refresh to 5GHz and above. We’ll check.

Power management PWM controller ISL69138 from Renesas Electronics which, judging by the official documentation, supports a maximum of seven phases. Therefore, in reality, the power subsystem is working according to the scheme 6+1. Just phase GIGABYTE AORUS PRO Z390 required to operate the CPU, a dual, and this, as you know, a great springboard for marketers. So, each channel includes a pair of inductance coils, two field-effect transistor SiC634 from VRPower and, accordingly, the doubler Renesas Electronics ISL6617A. Well, we are seeing a nice set for the Board in the medium price range. The MOSFETs marked “hold” the current up to 50 A.

About the power Converter Z390 GIGABYTE AORUS PRO, I’ll tell you in detail in the second part of the article.

For the power elements of VRM zones correspond fairly massive aluminum radiators that are connected to each other using copper heat pipes.

Coming to the CPU market Intel Refresh Coffee Lake has become a landmark event. Still, with the advent of processors with eight cores completely stuck in the role of standard option for the productive desktop, leaving no space in this niche for chips past generations with six or four cores. So it is not surprising that the new osmeterium we try to pay as much attention they really deserve. And at the moment we have published three expanded material about eight Coffee Lake Refresh, which is strongly recommended reading:

However, Coffee Lake Refresh is not only fosmidomycin. It is an absolutely full-fledged processor family, which in the relatively near term will stretch across all market segments, starting from the top, which is now home to the processors with eight cores, and ending with the budget, which are intended for Quad core or even dual core CPU. The massive expansion of the habitat Coffee Lake Refresh is expected by the end of the first quarter of next year, when Intel will finally be able to more or less cope with all your production problems, but now such processors to identify with only one osmeterium impossible.

The fact that the family of Coffee Lake Refresh Core models thousandth of the series, in its present form includes three members of which have eight cores, only two. Along with the OCTA-core Core i9 shestnadcatiletnim-9900K and OCTA core, but devoid of support Hyper-Threading Core i7-9700K, microprocessor giant was released also six-core processor Core i5-9600K. At first glance it looks like the long-available Core i5-8600K. However, it is a full analogue of the he did not is because Core i5-9600K using the same semiconductor base, as in the eight-core Core i9-9900K and Core i7-9700K. That is, Core i5-9600K is a six-core processor built on eight-semiconductor crystal Lake Coffee Refresh with a couple of deactivated cores.

To understand the causes of Core i5-9600K one company with Core i9-9900K and Core i7-9700K not so difficult. No matter how perfected to the present time the 14-nm process technology, Intel is still in need of implementation of the chips defective in the production of senior Coffee Lake Refresh. Semiconductor crystals eight cores have an area of about 174 mm2, and the appearance defective chips in the defective individual cores or partly failure of the cache memory when it is inevitable. The existence of Core i5-9600K lets not write them off to the scrap and to use efficiently – in a processor with reduced a quarter the number of cores.

Technological affinity is a Core i5-9600K with eight-core Core i9-9900K and Core i7-9700K, not Core i5-8600K something even plays into the hands of users. Use to release a six-core derivative of the Coffee Lake Refresh the approaches and processes of making Core i5-9600K unique offer – shestiyadernik with solder under the CPU lid. And this means that the Core i5-9600K may be much more interesting to overclock than the Core i5-8600K, where internal is polymer thermal interface thermal grease with a fairly mediocre thermal conductivity. In other words, Core i5-9600K better than the Core i5-8600K, at least the fact that it does not need to scalp.

While Core i5-9600K inherited one of the main trumps its predecessor – a relatively affordable price. Officially, the new shestiyadernik valued at $262, that is, it is more expensive than the Core i5-8600K, just four dollars. And what’s more, at a price close to the recommended, it is really possible to buy, in contrast to the same Core i9-9900K and Core i7-9700K, the availability of which sell extremely limited, but real retail prices have nothing to do with the official.

It is not surprising that practical aspects of the operation of such a processor are of genuine interest. After all, Core i5-9600K in the family Coffee Lake seems to Refresh the current reality the most beneficial option in terms of performance and price, since it offers the lowest unit cost of the core. Given all this, we decided to dedicate six-core Core i5-9600K a separate review which will definitely answer the question of how consumer quality of this novelty are correlated with the its predecessor, the Core i5-8600K.

#Core i5-9600K in detail

So, Core i5-9600K is the most affordable desktop processor Intel, built on the design of the Coffee Lake Refresh. He has only six, not eight cores, but he is younger and cheaper OCTA-core sibling in the face of Core i7-9700K — 30% from the point of view of official prices or more than 40%, in terms of real prices.

Like its relatives, Core i5-9600K is a modern version of intelliscore 14-nm process with the conditional name “++ nm 14” and has an unlocked multiplier, theoretically allowing for easy overclocking. Like all other proposals for the platform LGA1151v2, Core i5-9600K is based on the microarchitecture Coffee Lake and is equipped with integrated graphics core UHD 630 Graphics (GT2).

Despite the fact that according to the model number between the Core i5-9600K and Core i5-8600K an abyss, the processors are quite similar in passport characteristics. The translation series Core i5 design Coffee Lake Refresh Intel did not change any fundamental parameters. Core i5-9600K as Core i5-8600K, remained shestiyadernik without the support of Hyper-Threading with the cache memory of third level rate of 1.5 MB per core (9 MB in total).

At the same time, the diagnostic utility CPU-Z allows you to verify that the basis of the Core i5-9600K on a different semiconductor chip, a new modification of the P0, U0 and not used in processors Coffee Lake last generation, in which the number of compute cores was not more than six.

This means that from the point of view of the internal structure Core i5-9600K – only a distant relative Core i5-8600K. In the new shestiyadernik uses the same OCTA-core semiconductor chip, as in Intel Core i9-9900K and Core i7-9700K, but with the pair locked at the stage of production of cores. And from this follow important conclusions. First, this means that Core i5-9600K present the first hardware package fixes against vulnerabilities Meltdown and L1TF (Foreshadow). Second, the memory controller that the processor is certified to support 128 GB DDR4 SDRAM, which will be set after an upcoming appearance in the sale of a 32-Gigabyte modules.

Notable differences Core i5-9600K Core i5-8600K is in clock frequencies. New shestiyadernik has a 100 MHz higher base frequency and more aggressive turbo mode, allowing it to accelerate to 4.6 GHz with low-flow load vs 4.3 GHz its predecessor. Best clock speed in turbo mode Core i5-9600K promises and under full load on all cores. Set it to 4.3 GHz, while the Core i5-8600K in the same conditions works only on 4.1 GHz.

Fully frequency characteristics of turbo for new and old LGA1151v2 processor collected in a table.

1 core 2 cores 3 core 4 cores 5 cores 6 cores 7 cores 8 cores
Core i9-9900K 3,6 5,0 5,0 4,8 4,8 4,7 4,7 4,7 4,7
Core i7-9700K 3,6 4,9 4,8 4,7 4,7 4,6 4,6 4,6 4,6
Core i7-8700K 3.7 V 4,7 4,6 4,4 4,4 4,3 4,3

Core i5-8600K 3,6 4,3 4,2 4,2 4,2 4,1 4,1

Speaking of Intel Core i9-9900K and Core i7-9700K, we noted that their operation on the maximum frequency stated for turbo speed, leads to higher heat dissipation and power consumption far beyond the limits of TDP, traditionally installed in a 95 watts. Therefore, the work of fosmidomycin on the frequencies given in the table above, is possible only with active functions of the Multi-Core Enhancements, which abolishes all restrictions on energy consumption, and assuming the use of high-quality motherboards and powerful cooling systems. With Core i5-9600K situation should be easier. In multi-threaded load stress test Prime 95 29.4 (Small FFT with AVX), real consumption Core i5-9600K a quasi-nominal mode with active Multi-Core Enhancements at a frequency of 4.3 GHz is “only” 115 watts. And this means that in a typical common applications, this processor is working at maximum turbocheetah, most likely, 95-watt border will appear.

Core i5-9600K, like other desktop processors generation Coffee Lake Refresh, compatible with any LGA1151v2-motherboards, built with the help of those chipsets with the numbers from the fourth hundreds. In boards based on Intel Z390 new shestiyadernik will work out of the box, and for boards on Intel Z370, H370, B360 and H310 may need a BIOS upgrade.

#Temperature and energy consumption

The Coffee Lake Refresh processors differ from their predecessors not only the increased clock rates and increased (in older versions) number of compute cores. At the Core i9-9900K, Core i7-9700K and Core i5-9600K also changed the internal termoenergetyczny material laid between the semiconductor crystal of the CPU and the CPU cover. In all three models is the polymer thermal paste now use metal solders with much higher conductivity.

The appearance of solder at fosmidomycin – partly as a necessary if not an efficient thermal interface, Core i9-9900K and Core i7-9700K would not be able to take those frequencies that are promised to them turbo because of banal overheating. The same six-core Core i5-9600K got the solder out of inertia, and it is in this processor, the positive impact of thermal interface with high conductivity can be seen more clearly.

To illustrate, we carried out a simple experiment: compare temperatures and energy consumption Core i5-8600K and Core i5-9600K when configuring them on the same frequencies with the same supply voltage. The results are presented below: the tables below show the limit value virtually measured temperature and energy consumption of CPU when checking stability in the stress test Prime95 29.4 (six strand under full load Small FFT AVX c). The cooling of the processors during the test was carried out the same air cooler Noctua NH-U14S.

Core i5-8600K:

Core i5-9600K:

The results allow to make several conclusions in relation to the semiconductor crystal Lake Coffee Refresh and a new internal thermal interface. But first and foremost catches the eye is the fact that, despite the use for the production of processors, Coffee Lake Coffee Lake and Refresh the same process technology 14 nm++, as newer semiconductor crystals has really improved. It is expressed in that the Core i5-9600K is able to take the same frequency as Core i5-8600K, at a lower voltage.

At the same time, the new six-core processor with a design Refresh Coffee Lake shows ceteris paribus the higher power consumption. If you select the same voltage and frequency of the Core i5-9600K consumes 15-25% more power compared to the Core i5-8600K that is obviously due to the increased size and complexity of the underlying semiconductor crystal.

However, increased power consumption and heat generation Core i5-9600K to the growth temperature does not. On the contrary, new shestiyadernik is prone to functioning in a more benign temperature conditions. At equal voltage and frequency of Core i5-9600K is about two to three degrees cooler than its predecessor. But if to compare between a state with roughly the same power consumption and heat dissipation, the advantage of the representative of the family of Coffee Lake Coffee Lake Refresh before they reach the level of 10-15 degrees. That is exactly what manifests the positive impact of the new thermal interface: it allows to cool the CPU crystal is more efficient than before, when Intel used solder, thermal compound and the polymer. And this, in turn, enables Core i5-9600K to work without overheating at a much higher heat dissipation.

In the end, the advantage in temperature entails and the best acceleration. As follows from experimental data, the frequency of the Core i5-9600K manages to raise about 100 MHz higher than Core i5-8600K. However, this advantage can hardly be considered some special success. High heat dissipation Core i5-9600K, originally built on an eight-semiconductor crystal, almost completely negates the entire gain in the temperatures derived from the solder. Overall, therefore, no special overclocking achievements from the new shestiyadernik is not expected. And moreover, it seems that the best results in overclocking you can achieve all the same Core i5-8600K if pre-scalp.

#Acceleration

If you carefully read the preceding section, you probably know that you can count on some epic overclocking Core i5-9600K clearly not worth it. So, the maximum frequency at which our instance of processor was able to work steadily and to undergo stress testing, steel 5.0 GHz. Performance in this mode was achieved when setting the VCORE in the range from 1.25 to 1.28 In with the inclusion of the penultimate level Load-Line Calibration.

As you can see from the above screenshot, more serious overclocking is due to high energy consumption and heat dissipation Core i5-9600K. If you raise the voltage above 1.28 is In, the temperature of the CPU cores goes straight out of bounds, causing the throttle. But if the tension leaving at this level, for frequencies above 5.0 GHz the processor does not pass the test on the stability in the stress test Prime 29.4 (Small FFT with AVX).

Nevertheless, Core i5-9600K accelerates still better than all eight Coffee Lake Refresh that have passed through our hands before. The previously tested Core i9-9900K and Core i7-9700K overclocked reached frequency of about 4.8 GHz, and this allows to conclude that reducing the number of active cores in the Core i5-9600K slightly lowered his dissipation and increased frequency potential. But this is still not enough to Core i5-9600K it would be possible to calculate more advantageous alternative for overclocking Core i5-8600K. The difference within the overclocking of these processors are not as essential, while the classic Coffee, Lake in the reserve there is a hidden reserve: it at desire it is possible to scalp.

In addition, when overclocking Core i5-9600K unusually large attention should be paid to cooling. The dissipation of this processor when overclocking is not less than fosmidomycin, and to remove and dissipate more than 200 watts only the chosen coolers with high efficiency. For example, in the experiments we used the super-cooler Noctua NH-U14S, and rely on the cooling system less efficient, we would not recommend it. Much in overclocking Core i5-9600K depends on the quality of the implementation of the power Converter on the motherboard, which should provide a stable voltage with a significant increase in current. Unfortunately, on the market of motherboards meet this requirement, not all products even the ones that are relatively expensive.

This time we overclocked the processor without lowering the multiplier in the performance of AVX-instructions. However, as in the case with the older Coffee Lake Refresh, setting a negative 200-megagertsevym Delta for CPU frequency when working with AVX instructions would allow to obtain higher performance in applications that do not use vector data. In other words, the frequency of 5.2 GHz when you work exclusively when working with 32 – bit and 64-bit scalar data for Core i5-9600K quite real.

With the release of the desktop Core processors, the ninth generation, Intel was finally able convincingly to answer his age-old rival, began deliveries to mass market chips with eight cores. Innovations in the face of the Core i9-9900K and Core i7-9700K immediately appeared in the center of attention, but largely not for the most obvious reason. At the fore is not so much a discussion of the advantages of these processors before senior Ryzen how pricing and availability is to buy the Intel fosmidomycin at the prices close to the recommended, today is simply unrealistic.

However, no matter how many complained about the high cost of ordinary people, staunch supporters of Intel is not stopping. If we talk about the capabilities and performance of the language of facts, in addition to increased to eight the number of cores older Core thousandth of a series of bribery and high nominal frequencies. As a result, their performance is certainly higher than the older mass Ryzen processors and Core i7 past generations. So it seems that Core i9-9900K and Core i7-9700K – a kind of uber-processors, which not only has no equal in the mass segment, but also who will hold the position of flagship in the foreseeable future, becoming a sort of Islands of stability in a changing world desktop where the paradigm shift and transition from chetyrehjadernogo to cosmedent has just happened in the last couple of years.

As for the cost, today the youngest of those of fosmidomycin, Core i7-9700K, already can be considered as an option for the top-level configurations. Of course, the price of 35 thousand rubles at the officially announced value of $374 it is difficult to call humane, but at least against the prices of older graphics cards family GeForce RTX this amount does not cause complete rejection. So it is not surprising that buyers on Core i7-9700K are, and, as experience shows, it is sufficient.

And I must say that those who are not waiting for the cheaper Core i9-9900K, and takes Core i7-9700K right now, it is possible to understand. Considering all the pros and cons, we cannot say that the flagship of the family Core i9 by far the better of his brother with a lower positioning. The fundamental difference between Core i7-9700K is the lack of support for Hyper-Threading, but due to the nature of the technology used to perform two independent flows of resources of a single computing core, many modern games and applications not only benefit from growth, but often on the contrary, suffer from it. In addition, according to the latest news, Hyper-Threading is a serious problem in the security system, and some developers are even calling for its complete shutdown. Therefore, the configuration built on the younger inalaska osmeteria latest generation Core i7-9700K – quite good option, which is not ashamed to recommend how to work a computer, and for “maximum” gaming build.

In this article we decided to discuss in detail how the owners of the systems built for Core i7-9700K, can further “improve” their platform. We will focus on acceleration. One of the key features Core thousandth of the series was the return of Intel to use between the heat-dissipating cover and the CPU crystal beshlyaga solder with high thermal conductivity.

For this reason, many were waiting for new fosmidomycin another step forward in the part of overclocking potential. But there it was: generation Refresh Coffee Lake was very hot even without any overclocking and, as shown by the initial testing, and so they operate at frequencies close to the limit.

However, we decided to go back to overclocking the Core i7-9700K again. This time we turned to our long-time partner, computer store,”regard“, and took for testing multiple serial processors. With their help, we have tried to establish as far as possible to raise the performance of the platform on the basis of the usual Junior intelestage of osmeteria, if we approach the question carefully and systematically. And as a result we were able to deduce the algorithm that, in spite of all obstacles, allows you to overclock average retail Core i7-9700K to “beautiful” rate of 5 GHz.

#Core i7-9700K: characteristics and features

So, Core i7-9700K – it is the most affordable desktop Intel CPU with eight cores. Its price is set at $374, and from the point of view of formal positioning it is between $ 500 osmeterium Core i9-9900K 262 and $ shestiyadernik Core i5-9600K. Like its relatives, this processor is the most modern version intelliscore 14-nm process with the conditional name “++ nm 14” and has an unlocked multiplier, theoretically allowing for easy overclocking. Like all other proposals for the platform LGA1151v2, Core i7-9700K is based on the microarchitecture Coffee Lake and has an integrated graphics core UHD 630 Graphics (GT2). Built-in dual channel memory controller of this CPU officially supports modes up to DDR4-2666 that no news is not, but at the same time he is able to address up to 128 GB of memory to install in the system will become possible after the advent of 32 GB DDR4 SDRAM. It should also be noted that in the Core i7-9700K appeared first hardware security patches Meltdown and L1TF (Foreshadow).

Support Hyper-Threading technology have always been a mandatory attribute of the family of processors Core i7. But that was in the era of Quad-core and six-core CPU, when it allows such processors to process eight or twelve threads simultaneously. With the release of the Core i7-9700K everything changed: the virtual CPU number of cores does not support, but as the tests show, it is still in most cases significantly more productive Core i7-8700K, because the two additional physical cores able to make a greater contribution to performance in comparison with Hyper-Threading.

Like the Core i7-8700K, the new Core i7-9700K has a L3-cache and the volume of 12 MB. In other words, the amount of cache in terms of the core was reduced to 1.5 MB and this is another sign that the Junior OCTA core Coffee Lake Refresh differs from his older brother.

As the nominal clock frequency for the Core i7-9700K specified 3.6 GHz, which corresponds to the nameplate frequency Core i9-9900K and 100 MHz below the frequency of the Core i7-8700K. However, users in the assessment of consumer qualities have long been accustomed to look not at the nominal frequency, and the speed that is advertised to turbo mode. And it Core i7-9700K looks much more interesting 200-300 MHz surpassing the indicators defined for the Core i7-8700K. Unfortunately at 5.0 GHz under single threaded load Junior cosmedent still lacking, but nevertheless, at 4.6 GHz full load on all eight cores promise a very decent performance.

Base frequency, GHz Frequency in turbo mode, GHz
1 core 2 core 3 core 4 kernel 5 cores 6 cores 7 cores 8 cores
Core i9-9900K 3,6 5,0 5,0 4,8 4,8 4,7 4,7 4,7 4,7
Core i7-9700K 3,6 4,9 4,8 4,7 4,7 4,6 4,6 4,6 4,6
Core i7-8700K 3.7 V 4,7 4,6 4,4 4,4 4,3 4,3
Core i7-8086K 4,0 5,0 4,6 4,5 4,4 4,4 4,3

However, there is an important caveat, which is at the root of all change. Specification assumes that the operating frequency in turbo mode can increase only as long as the power consumption (and heat dissipation) of the processor remains within acceptable limits. These limits for those processors are defined three basic constants:

  • PL1 – limit processor power consumption, which should not be exceeded for long-term work;
  • PL2 is the peak processor power consumption, which should not be exceeded during short-term increase of the load;
  • Tau – the maximum time during which the power consumption of a processor is allowed to go beyond the PL1, remaining however below PL2.

Intel suggests that the PL1 limit should correspond to the thermal package of the processor, i.e. Core i7-9700K is 95 watts, while the limit PL2 is set to 120 W, and the time Tau during which the processor is allowed to consume more than 95 watts, but less than 120W, limited to 1 second. And it is very hard requirements, which severely restrict the frequency formula of the processor. That is, if we talk about the nominal specified antalovsky specification working mode Core i7-9700K, to accelerate to 4.6 GHz and higher it is able only in the case of quite light load. If we are talking about complex computational algorithms, the frequency determined by the parameters PL1 and PL2, are significantly below given in the table above highs.

As a simple illustration, we present the distribution of the real frequencies, which honestly is configured according to the specifications of Core i7-9700K when rendering in Blender using different numbers of compute cores.

As you can see, under heavy load, the achievement frequency of about 4.6 GHz is more the exception than the rule. High frequency close to the maximum allowed under the turbo mode, is achieved only under light load, when the power consumption of the processor does not cause any problems. In the case of load on all the cores the frequency is set closer to 4.2-4.3 GHz, that is by 300-400 MHz below the limit values. Naturally, the attainable frequency dependent on the nature executed by the processor algorithms, but the main thing here is that if you configure the CPU to be honest, the frequency formula Core i7-9700K, sandwiched within the 95-watt thermal package, looks not so great as it seems at first glance. But in this case, the consumption and dissipation of the processor really fit in the declared limits.

However what you can see in the graphs above is rather theoretical or even hypothetical situation. The fact is that in the pursuit of performance, motherboard manufacturers antalovsky specification is neglected. Into use long ago introduced the Multi-Core Enhancements, which negates all the requirements antalovsky specifications regarding the power consumption and heat dissipation, and outputs the processors to the maximum possible for a given load frequency. Formal language this means that the Board increase the threshold values PL1 and PL2 to unattainable in real life, and as a result, the processor gets the opportunity to work on unrestrained maximum frequency, depending only on the number of cores loaded with work.

Having exactly the same test Core i7-9700K when rendering in Blender with enabled Multi-Core Enhancements, you can observe quite a different picture frequency.

However, you need to understand that when the system is in this mode, neither of which is a 95-watt thermal package CPU it is not. Picture of real consumption begins to look like the following.

The conclusion from all this is quite simple. If you are going to use Core i7-9700K with the inclusion of Multi-Core Enhancements, the rated thermal package 95 W for you to absolutely nothing. In reality, the processor will consume up to 150 or even 200 watts, and the power supply and cooling system in this build you need to choose accordingly. Also, do not forget that Multi-Core Enhancements – a kind of acceleration, and guarantees long-term stable and trouble-free operation of the system in this mode, no one gives.

A little more about the practical part of this acceleration we will discuss in the next section. But before we get to the actual test results, a few words should be said about the processors that we tested. All the calculations made in this material is derived from testing five specimens of the serial Core i7-9700K series (FPO) L834F584.

The explanation of this marking allows to conclude that these processors are made in Malaysia at the end of August, that is two months late samples to the press that Intel offered for eight related innovations. And this means that all conclusions which will be made hereinafter, is absolutely relevant for students in the retail network, CPU.

#Overclocking Core i7-9700K enabling Multi-Core Enhancements

Through the efforts of motherboard makers feature Multi-Core Enhancements (MCE) is ubiquitous in common parlance and no longer perceived as a form of overclocking. However, it is this: MCE is the real acceleration, which switches the CPU to non-standard modes. Moreover, as we will show further practical examples, – acceleration in the case of Core i7-9700K hard enough.

The essence of MCE is that the processor when the operation is permitted not to follow their energy consumption and to achieve maximum possible under the turbo mode frequencies that depend only on one parameter – the number of busy cores. But if the Quad and partially shestidennomu such assumptions are not entailed any particular problems and had little or no consequences to obtain an additional performance boost, with Core i7-9700K not so simple. Devoid of any limitations on the power consumption OCTA core processor Refresh Coffee Lake are heated much stronger than the predecessors. This is not only because of the increased number of cores in the semiconductor chip, but also because they have a higher maximum permitted frequencies, the designated manufacturer of “arbitrary decision” without any preconditions in the form of improved process technology. And ultimately Core i7-9700K enabled MCE can consume electricity and, consequently, allocation heat two to two and a half times the amount specified in the spec of 95 watts.

This means that if you plan on a system with Core i7-9700K to use MCE, you should be sure to take care of a good motherboard with the powerful Converter power supply for high-quality cooling of the processor, which should be able to cope with the dissipation of over 200 watts of heat. We were convinced immediately when they began to check taken to test the processor in the nominal mode. Even a simple test of stability, Prime95 29.4 after enabling the MCE has become for them a problem. And despite the fact that for cooling we used a fairly productive ITS a Corsair Hydro Series H115i, temperature test osmeteria neared the maximum allowed.

The following table shows the results of the practical test five serial Core i7-9700K in Prime95 29.4 (full eight strand SmallFFT load c AVX) with active Multi-Core Enhancements.

3 1,391 239 90 102
4 1,32 215 82 92
5 1,353 218 82 91

Obtained in the verification process, the results allow to make several conclusions. But the most important thing here is that a simple on MCE immediately translates Core i7-9700K in close to the limit mode. Moreover, some instances Core i7-9700K (as number 3 in our test), after you enable the MCE can even go beyond the maximum permissible temperature and to reduce the operating frequency because of the inclusion of a protection mechanism against overheating above 100 degrees – throttle. Moreover, recall that we performed the test with an efficient liquid cooling system, and therefore, when using more than simple coolers overheating and trottling CPU will provide almost one hundred percent probability.

In addition, you need to pay attention to another feature. Uniform removal of heat from the extruded multicore crystal Lake Coffee Refresh – not an easy task even with the Intel transition on efficient internal thermal interface. So eight cores always present a considerable temperature differential between cores, which can reach 10-12 degrees.

Overclocking with enable MCE BIOS of the motherboard is one of the simplest approaches, which on the one hand allows to obtain a significant performance increase, and with another – does not require any tedious setup. Moreover, contrary to the recommendations of Intel, on most motherboards MCE is enabled by default, and the user need only be attentive to the organization of the cooling of the CPU and make sure that in the process, there are no signs of thermal trottling.

Forcibly enable or disable the function of MCE can be in the motherboard BIOS. Usually basic CPU settings in the BIOS the option is rendered as a separate paragraph.

To activate the MCE is possible, and another, more low-level way – manually increasing the consumption limits PL1 and PL2 to unrealistically high values. The settings of these variables usually are in the BIOS section, dedicated power management processor.

Similarly, the values of these parameters to their certified values, 95 W, 120 W and 1 from the processor to ensure that it will function as intended by Intel and not as I wanted the manufacturer of the motherboard.

#Overclocking Core i7-9700K manually

Overall, overclocking Core i7-9700K manually, instead of using the finished profile Multi-Core Enhancements, usually allows you to achieve more. However, due to the very high heat dissipation new eight-core processors, too much should not be expected. As practice shows, shestiyaderny Core i7-8700K accelerates better new products, especially if the procedure frequency to Preface the scalping and replacement of internal polymer interface on the liquid metal.

Thus, stable operation at a frequency of 5.0 GHz for Core i7-8700K not considered something out of the ordinary. But to disperse similarly Core i7-9700K almost unreal. To get this processor stable on 5.0 GHz only serious assumptions and indulgences in the criteria. The fact that the new processors Coffee Lake Refresh the internal thermal interface is used solder, not thermal grease, no special trump card of these processors is not. A better internal thermal interface only compensates for the increased dissipation of osmeteria but to some impressive frequency during acceleration it allows.

By itself, the process of overclocking Core i7-9700K fairly typical and is based on the usual algorithm: the increase of the supply voltage to increase the operating frequency – stability check. But, as in the case of all other processors, osmeterium has its own nuances, which we will discuss a little further.

Check five copies of the series Core i7-9700K allows us to conclude that in most cases, you should rely on overclocking the CPU up to a frequency of 4.8 GHz. Below we provide detailed information about the dispersal of all tested processors: data on modes in which stable operation is achieved and the limit values of temperature and energy during the passage of the test in Prime95 29.4 (full eight strand SmallFFT load c AVX).

Indeed, experience shows that the average result of overclocking Core i7-9700K – proven stability is the frequency of 4.8 GHz. Thus, there may be processors that are capable of taking and a higher frequency, but at the same time, we ran and unsuccessful instance, the maximum acceleration for which was the frequency of 4.7 GHz.

The obtained results fit well to the statistics of shop Silicon Lottery, which is engaged in pre-sorting of the processors on a regular basis. According to him the frequency of 4.7 GHz take 100% of the instances of the Core i7-9700K, stable and working on 4.8 GHz 69 % of all processors, and the frequency of 4.9 GHz submits in 29 % of cases.

The best overclocking Core i7-9700K is achieved when the voltage V– CORE from 1.3 to 1.375 V. plays an Important role and set Load-Line Calibration (LLC) to counter the voltage drop with increasing current through the Converter power CPU. As practice shows, the greatest efficiency showing average levels LLC, when the CPU voltage at extreme loads is still slightly sags relative to the selected level. For example, ASUS motherboards with eight-step adjustable LLC recommended levels of Level 5 or Level 6, for ASRock boards – Level 2.

The best tool to check the stability of the Core i7-9700K today programme is 29.4 Prime95 in SmallFFT mode. Using mathematical algorithms and check for ease of Mersenne numbers, it creates very high computational load, which heats the CPU more than the most common common programs. And passing such a test allows to be sure that in everyday use overclocked CPU no incidents will not occur.

In the extreme case to a new generation Coffee Lake Refresh Intel has allowed to relax the requirements to the temperature of processor cores. The maximum heating for the 14-nm CPU crystal is considered to be 100 degrees, but Core i7-9700K enable temperature throttle you can now move on 10-15 degrees higher. For this purpose, the motherboard BIOS has a new setting.

To use this trick makes sense when you check the stability of the using specialized utilities that warm the processors obviously stronger than the regular program. For example, if the test in Prime95 will run without errors at temperatures slightly above 100 degrees, nothing wrong with that. In daily work such heating of the CPU, obviously, will not arise. That is why in some tests of processors on the dispersal we made the output of the temperature over the 100 degree limit.

Overclocking Core i7-9700K to 4.8 GHz seems pretty skoromniy result that only 4% improves the frequency, some turbo-mode to load on all cores. Is this the absolute maximum ability new consumer fosmidomycin? Actually no, if you remember that the utility is Prime95 29.4 actively uses 256-bit AVX vector instructions, and this factor causes a strong heating of the processor when using it. Such vector instructions is not all software, and especially do not add them into their products game developers. This knowledge allows certain assumptions to push the bar for maximum overclocking a bit further.

Like its predecessors, the Coffee Lake Refresh processors in case if executable algorithms contain AVX/AVX2 instructions, can reduce the clock frequency multiplier. This makes it possible to limit the CPU speed when dealing with demanding tasks, choose a higher frequency for the simple and ordinary modes. And as practice shows, at voltages VCORE range from 1.3 to 1.375 V At which achieved better overclocking results, the average Core i7-9700K, if we are not talking about the activation of the AVX/AVX2-blocks of the CPU to maintain stability on the 5.0 GHz frequency up.

To configure the dual-frequency mode is very simple. If we talk about the usual Core i7-9700K, error passing tests in Prime95 29.4 at a frequency of 4.8 GHz, the base frequency for this processor should select 5.0 GHz, by setting the AVX Instruction Core Ratio Negative Offset (from different manufacturers boards it is also known as the Offset Ratio AVX, AVX Offset or Offset CPU Ratio When Running AVX), which reduces the CPU multiplier in the performance of AVX/AVX2 code, ask the decreasing frequency of 200 MHz.

The decrease in the frequency of Core i7-9700K in the execution of AVX instructions on a 200 MHz can be considered a standard recommendation, allows to obtain better performance. However, the Delta 200 MHz is still not universal. For example, for the CPU 2, which could work stably in Prime95 29.4 at the frequency of 4.9 GHz, frequency without AVX we had to limit the same magnitude 5.0 GHz because of 5.1 GHz it was unstable. But overall it looks like typical dual-frequency acceleration for Core i7-9700K, which can the majority of instances, is a 5.0/4.8 GHz.

By the way, to check the stability of operation of the processor in modes without AVX can the same utility Prime95 29.4 – support vector instructions it is easily disabled by editing the configuration file local.txt.

It is believed that severe heat those processors without AVX load instructions do not exist, but the Core i7-9700K ready to break the stereotype. As shown in the screenshot above, this processor to 5.0 GHz even when ordinary operations may not warm up to 90 degrees and demonstrate higher power consumption 190 watts.

This is another compelling indication that before you embark on any experiments with overclocking the new those of osmeteria in the first place it is necessary to ensure sufficient power Converter power supply on the motherboard and good CPU cooling performance. From motherboards for overclocking LGA1151v2 OCTA-core processors, we suggest a model with a OCTA-core power Converter. And among the coolers is better to choose SVO with radiators, size 240 mm or more, or air supercooler with the design of the type “two-piece tower”.
