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.

Prime95 29.4
CPU instance VID, Max. the power consumption of the CPU, W Max. temperature, °C
The coldest core The hot core
1 Of 1.34 216 82 91
2 1,353 213 83 91
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).

Instance 1:

Instance 2:

Instance 3:

Instance 4:

Instance 5:

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”.

#Design and capabilities

ASUS ROG MAXIMUS GENE XI established on the basis of a full form factor mATX, in which each side of the printed circuit Board has a length of 244 mm. We focus on it because the budget segment is common to encounter devices that have an even more reduced printed circuit boards approaching the size rather to the mini-ITX format.

ASUS ROG MAXIMUS GENE XI

Theoretically any Board form factor mATX allows you to unsolder the four expansion slots (compared to seven connectors from standard ATX). However, ASUS ROG MAXIMUS GENE XI includes just two ports, one of which — PEG, aka PCI Express x16 3.0. This connector is further reinforced. A makeshift metal frame called SafeSlot, according to ASUS, increases the strength of the port by 1.8 times under the load of fracture, and 1.6 times when the load on the pulling. Given the fact that “Jack” can realistically become the basis for a bench-bench, this strengthening PEG port clearly will not be superfluous, because sometimes a day has to switch the graphics card by 10 times and more.

Near to the CPU socket is a PCI Express x4 slot is four lines from the chipset, corresponding to the standard 3.0. The connector has no latch, so it can be set to anything — even video card. However, technologies like AMD CrossFire and NVIDIA SLI, consider the card does not support, so put here the graphics card makes no sense.

What PCI Express x4 wired, so to speak, the first is good. This fact, on the one hand, means that we can use in the system of a huge supercooler. So, no its Archon or Noctua NH-D15 does not overlap the main PEG port (as, however, and PCI Express x4).

Achilles ‘ heel ASUS ROG MAXIMUS GENE XI is considered close proximity of the two DIMM sockets to the CPU socket LGA1151-v2. The distance from the center of the socket until the first slot is only (!) 45 mm. This means that most tower coolers will block the DIMM ports required for installation of RAM. The Board supports the installation of ultra-fast modules of standard DDR4, which means that the system can use sets of RAM with extra large heat sinks, which moreover do not get along with supernumerary.

It is obvious that ASUS ROG MAXIMUS GENE XI “adapted” to the use of maintenance-free liquid cooling system, but here we catch the problems. So, the new “dropsy” NZXT Kraken X62, used in the stand also blocked the DIMM slots — because pipe and fittings this WITH the right. In the end had to deploy the new “Kraken” at 90 degrees, and this, dear readers, is the farm, because “water” has a lighted logo that implies a definite location (although the backlight can be disabled in the cooling device). So here you need a responsible approach to the selection of water cooling. For example, AMD A80 you have such problems will not arise.

By the way, the number of DIMM slots, I have no complaints. ASUS ROG MAXIMUS GENE XI is a device that will be used along with pricey components, therefore with very high probability the system will install the dual channel kit 32 GB. Install — and forget about the lack of RAM the next many years.

The DIMM slots are soldered so close to the CPU socket because of the attempts of engineers to ASUS to cram followed by another three connectors. Immediately behind the ports under the RAM are two M. 2 slots — they have a combined metal cap, which plays simultaneously the role of passive cooling. And behind them — DIMM connector.2 to install a special expansion card that is firmly entrenched in the top motherboards MAXIMUS series. Read more about it below.

M. 2 ports can install two SSD form factors 2242, 2260 and 2280 — each connector will only work in PCI Express 3.0 x4 (lines — chipset). They are covered with a large aluminum heatsink. He was, incidentally, can be removed only if the slot PCI Express x16 graphics card is not installed. To do this, Unscrew the two screws.

Hindsight, as you know, we are all strong. If I were the engineer at ASUS, the DIMM slots are pushed to the place under M. 2 drives, and the slots for the SSD ROG MAXIMUS GENE XI divided: one mounted above the PCI Express x4 or right of it, redoing chipsety radiator and moving the slot for the batteries; the second M. 2 would make vertical. Actually, the way it is implemented, for example, in ASUS Prime X299-Deluxe. Yes, that would be not so beautiful, but, in my opinion, more practical.

And still on the Board illuminated the entire right side and a large icon with the ROG on the plastic plug I/O panel. Also ASUS ROG MAXIMUS GENE XI is equipped with two 4-pin connectors for connecting led strips and other RGB peripherals.

In the DIMM slots.2 is a ROG branded motherboard DIMM.2. For the first time this design feature the “Republican” motherboards came from ASUS Maximus IX Apex, which was published in 2017. To the slot supplied eight lines PCI Express 3.0 from the CPU. Therefore, if we use it, the only PEG-device port automatically operates in the x8 mode.

The design of the DIMM card.2 changed again, and the new variant is passive cooling for SSD. The Board itself allows you to install two M. 2-drive up to a length of 110 mm each.

Due to this configuration, the M. 2 ports, in particular, the motherboard has only four SATA connectors 6 GB/s. But the gaming PC, a number pad would be sufficient.

ASUS ROG MAXIMUS GENE XI is equipped with seven 4-pin connectors to plug the fans. For mATX Board is a great figure! In this part of connector (five) highlighted in black — they allow you to regulate the speed of not only the “Carlson” with a shim. Therefore, there is no need to use additional device like a fan controller, or pick a case with a built-in controller for the fans. Beauty! The remaining two connectors — white, they can’t lower the speed. They can “hang”, such as fans with originally low speeds.

There are 4-pin connectors, generally successfully. For example, we use a small Tower case and a two-piece DLC. Pump and fans “dropsy” are connected to the top row of connectors. Corpus impeller, located on the rear wall, to the socket near the PCI Express x4 slot, and the front Cabinet fan — port W_PUMP located on the bottom and deployed at 90 degrees. This port will be useful to those who collect custom DLC along with ASUS ROG MAXIMUS GENE XI tank with a pump usually mounted in the lower part of the Tower housing.

Yes, all the connectors are located at the bottom of the PCB, deployed 90 degrees. This is because the video card with a three slot cooler will simply cover that area of the motherboard. Interesting ports internal I note the presence W_IN/OUT W_Flow — these connectors are monitoring the temperature of the refrigerant and the speed of the liquid flow in the cooling system. And yet the Board there is a connector Node is required to connect a compatible power supply. If you do, you will be able to control the fan speed of the PSU, as well as to follow the input and output voltages. The list of compatible hardware can be found here.

Panel I / o Board is equipped with an integrated plug. It is quite tightly Packed the various ports — in addition to the five analog audio jacks and optical S/P-DIF output, it is possible to detect the display’s HDMI output, combo PS/2 port (still needed during extreme overclocking, since the USB controller in a stressful environment can “fall off”), set of USB ports, including a new-fangled Type-C, Gigabit network, and even two buttons ClearCMOS and USB BIOS Flashback.

Wired network connection is created using the Intel I219-V and wireless — by Wireless-AC 9560, which, in addition to the standard Wi-Fi 802.11 a/b/g/n/ac with a capacity of up to 1733 Mbps, and supports Bluetooth 5.0.

Sound in ASUS ROG MAXIMUS GENE XI, as in many other ROG-boards, meets the audio codec, Supreme FX, which is based on the familiar Realtek chip ALC1220A. The manufacturer claims that he gets “exclusive version” of this chip, therefore, the name of the second letter A. In comparison with the “standard” Realtek ALC1220 the ratio of “signal to noise” from “elite,” 113 vs 108 dB. Traditionally, expensive boards in the composition of the audio included high-quality Nichicon capacitors and operational amplifier RC4580 OPA1688 and production Texas Instruments. The audio chip is shielded, and all elements of the sound system is separated from the other components of the PCB strip, which does not conduct current.

All series motherboards MAXIMUS suitable for overclocking and ROG MAXIMUS GENE XI and for extreme overclocking. Therefore, the Board has several overclocking “uluchshayzerov” that make life easier for young and not so young enthusiasts. Buttons power and reset, as well as the POST indicator signals it is easy to notice. And in the right part of the PCB there are indicators QLED that demonstrate, at what stage is the computer is booted. There are also ReTry button (instantly reboots the system) and Safe Boot (runs stand with secure settings). Add to this the switches MemOK! Pause (the PC is put on pause so the user can change parameters during execution of the benchmark) and Slow Mode (instant reset CPU multiplier to 8x, to accommodate the computer severe tests). Finally, in the bottom of the device are the contact track ProbeIt, allows using the DMM to measure the exact parameters of the main stress system. It is really unfortunate. When you use graphics cards with three slot cooler for her not to get close (or get close, but then you have to work a soldering iron). Anyway to run the probe near the rotating fan 3D accelerator — so.

 

The power of the CPU is made by two 8-pin connectors. Don’t forget that power supply with this cable set do not occur very often, and basically we are talking about powerful devices — watts on the 700 and more. However, the additional power to the processor is necessary only in extreme cases.

At the core of the Converter power supply ASUS ROG MAXIMUS GENE XI is a PWM controller ASP1405I. It may seem that the Board is equipped with 12 phases, but it is not. Each channel is responsible for the operation the CPU is equipped with two inductors and two assemblies IR3555. Two single-phase “look out” for iGPU. Looks power Converter very powerful.

During the cooling of field-effect transistors meets an array of a pair of aluminum radiators is of medium size, combined, however, copper deplorable. About how effectively the system works cooling the VRM area in the acceleration, I will tell you next.

The Intel Core i5-9400F: fake Coffee Lake Refresh

Advertisement
40658034 Apple 13.3" MacBook Air - Intel Dual Core i5 1.8GHz, Turbo Boost up to 2.9GHz, 8GB RAM, 128GB SSD storage, Intel HD Graphics 6000, 12 Hour Battery Life, 802.11ac Wi-Fi, Mac OS Sierra - MQD32LL/A

Despite the obvious difficulties with the production of 14-nm chips in sufficient quantities, Intel continues to gradually expand the lineup of Core processors, the ninth generation, known under the code name Coffee Lake Refresh. However, given it to her with varying degrees of success. That is, formally in the lineup really added new products, but in retail they appear very reluctant, and some models presented immediately after the New year novelties have been unable to check in the stores until now.

However, based on official data, now for the platform LGA1151v2 there are already at least nine desktop models of the Core pertaining to the thousandth of the series, including processors with four, six and eight cores. Moreover, the composition of this family includes not only the obvious representatives with predictable characteristics, but also unexpected CPU that is different from all predecessors ideologically. We are talking about CPUs F-series mass desktop chips, the specifications of which is not stated integrated graphics core.

Surprising in their appearance that these deals have expanded the range of consumer Intel for the first time in the last eight years, during which the company offered for mass segment only solution with integrated graphics. But now something has changed and the microprocessor giant has been forced to revise his principles. And we even know that: failures in planning and difficulties with the commissioning process with a 10-nm standards has led to a serious lack of Intel on the market, to mitigate which the company is trying by all means. The release of processors without integrated graphics – one of the rather apparent measures aimed at achieving this goal. Thanks to it the manufacturer has been able to set a serial processor previously considered defective semiconductor workpiece with a corrupted graphics core, which even at eight Coffee Lake Refresh “biting” up to 30 % of the area is 174 mm crystal. In other words, such a measure capable of increasing the yield and significantly reduce waste.

However, if Intel is the point in the release of processors F-series is quite obvious, that Benet from the emergence of such offers consumers the issue is very controversial. The chosen manufacturer of the tactic is that trimmed at its core, the processors are implemented without any discounts, for the same price as their “full” counterparts. In order to fully understand this situation, we decided to take the tests one of the Core lineup of the ninth generation, devoid of the integrated graphics and try to find his hidden advantages.

As the object for investigation was selected as Core i5-9400F Junior six-core CPU generation Coffee Lake Refresh. This chip of particular interest: its predecessor, the Core i5-8400, at the time, was very popular thanks to very attractive ratio of price and performance. Officially announced four months ago, Core i5-9400 (no F in the name) offers a slightly higher frequency such at the same price, but selling him is practically impossible. But the Core i5-9400F represented on the shelves everywhere, and, moreover, since the deficit of this model does not apply, its real value in retail as close as possible to recommended. However, this does not Core i5-9400F a good option for “basic” configurations automatically, because now AMD in the same price category offers six-core processors Ryzen 5, which, in contrast to the Core i5 series have the support for multithreading (SMT). That is why today’s quiz promises to be especially meaningful: it must give an answer to several questions and clearly show whether the Core i5-9400F chance to repeat the success of the legendary Core i5-8400.

#Lineup Refresh Coffee Lake

To date, there have been two waves of announcements of processors that are conditionally related to the generation of Coffee Lake Refresh. Despite the fact that such a CPU is largely similar to its predecessors from the family of Coffee Lake, Intel refer them to the ninth generation of Core numbers and indices, start with the number 9. And if the Core i7 and Core i9 this distinction may be partly justified, because they first obtained an eight compute cores, the new processors series Core i5 and Core i3 got an increase in model numbers for the most part. In fact, they only offer higher clock frequency.

While no improvements on the level microarchitecture can not speak at all. And surprise, to be honest, it doesn’t matter. Intel practiced the concept of development is that the profound changes in processors attached to the improvement of production technologies. Therefore, the delay in the implementation of the 10-nm process technology lead to the fact that we once again have to deal with the Skylake microarchitecture, released in 2015. However, what is surprising for some reason Intel does not seek to change features that do not require any noticeable change. For example, the official Coffee Lake Refresh continue to rely on dual DDR4-2666 memory, while AMD has repeatedly adds to its processors support high-speed modes, reaching in the latest versions of mobile Raven Ridge already up to DDR4-3200. The only thing that made Intel, is increased up to 128 GB of memory supported in systems based on Coffee Lake Refresh.

However, despite the absence of changes in microarchitecture, Intel still manages to produce quite an interesting model, extensive methods – increasing the number of cores and clock frequency. The first wave of announcements Coffee Lake Refresh, which took place in October last year, brought three flagship overclocking of the processor, to conquer new frontiers of performance: OCTA core Core i9-9900K and Core i7-9700K, as well as six-core Core i5-9600K. With the second wave of the Christmas list for the latest processors added another six CPU easier. In the end, the full nomenclature of the Refresh Coffee Lake began to look like the following.

Cores/ threads Base frequency, GHz Turbocheetah, GHz L3 cache MB iGPU IGPU frequency, GHz Memory TDP, watts Price

Core i3‑9350KF 4/4 4,0 4,6 8 No DDR4‑2400 91 $173

The main part of the processors added to the released in the first place overclocking K-models later, consists of chips, deprived of the integrated graphics core. Technically Core i9-9900KF, Core i7-9700KF and Core i5-9600KF are based on exactly the same semiconductor Foundation, and have absolutely the same characteristics as the Core i9-9900K, Core i7-9700K and Core i5-9600K, differing only in the fact that they don’t offer the built-in GPU, in hardware blocks at the production stage.

But the list of innovations of the second wave can be seen and indeed a new model. First is the Core i3-9350KF is the only Coffee Lake Refresh Quad core processor with an unlocked multiplier. If you close your eyes to the lack of built-in GPU, it is possible to calculate an updated version of the Core i3-8350K, which was accelerated by adding Turbo Boost technology 2.0 and the newfound ability of automatic overclocking to 4.6 GHz.

Another more-or-less full new in the second wave it is possible to calculate Core i5-9400 and devoid of the integrated graphics Core i9 fellow-9400F. The value of these models lies in the fact that with their help, Intel has significantly lowered the cost of the Junior six-core Coffee Lake Refresh, allowing you to use the latest generation CPU in the configuration baseline. However, formal differences between Core i5-9400 from last year’s hit, Core i5-8400, not so much. Clock frequency increased by only 100 MHz, which is likely due to the desire of the microprocessor giant to leave your younger shestiyaderny within the 65-watt thermal package. As a result, the gap in the maximum frequency in turbo mode between the senior and the Junior six-core processors in the family Coffee Lake Refresh increased to 500 MHz, while in the generation of Coffee Lake it was only 300 MHz.

Judging from the specs, it seems that trump the new Core i5-9400 and Core i5-9400F on the background of the old Core i5-8400 really nothing. However, the specifications in this case do not give quite the full picture. During the announcement of the first Coffee Lake Refresh, Intel said, including about the advantages of an indirect nature. For example, for a new generation of chips was promised a change of the internal thermal interface: polymer place of thermal paste was to take a highly bestlady solder. But does this apply to the Junior six-core Core processors, the ninth generation? It turns out that not always.

#Details about Core i5-9400F

It so happened that, releasing the Coffee Lake Refresh processors, Intel raked in the pile, several different variants of semiconductor crystals with process technology 14 nm++, and not all of them are in fact new. Based on Core processors, the ninth generation may lie as semiconductor crystals, designed for them specifically, and relatively old versions of the silicon, which was used extensively including in the processors of the eighth generation ranked as family Coffee Lake.

In particular, at the moment aware of the existence of at least four stoppingof crystals that are set in a certain mass the Core of thousandth of the series:

  • P0 – the only “honest” option of the crystal, which is really unfair to make Coffee Lake Refresh. This crystal has eight cores and is used in overclocking the Intel Core i9-9900K, Core i7-9700K and Core i5-9600K in their F-variations of the Core i9-9900KF, Core i7-9700KF and Core i5-9600KF, as well as the Intel Core i5-9400;
  • U0 – six-core crystal used in processors Coffee Lake, that is, in the eighth generation Core. Now it is used to create a six-core Core i5-9400F;
  • B0 the Quad – core chip, which is used for the Intel Core i3-9350K. This version of silicon, too, came into the Quad-core processor straight out of the Coffee Lake, including the Core i3-8350K;
  • R0 – a new stepping of a crystal, in which it is assumed will be the senior Core processors, the ninth generation, starting in may. Currently, the serial CPU does not occur, and therefore no specific information about its features and causes no.

Thus, the Core i5-9400F about which we are talking in this review, is the black sheep: one of a kind processor that may be internal to the device is different from the other six-core and eight-core counterparts-generation Coffee Lake Refresh. Strictly speaking, it is not a stripped-down or time-lapse version of the Core i5-9600K or Core i5-9400, and a slightly overclocked variant of the old Core i5-8400 with disabled graphics core.

And I must say, this is manifested not only in the screenshots diagnostic utilities that show for the Core i5-9400F old stepping U0 instead of a new P0. In Core i5-9400F in fact, there is no innovation peculiar to Coffee Lake Refresh. In particular, the Assembly of these chips soldering the die to the heat-spreading lid is not applied, and the internal thermal interface is exactly the same polymer compound used in processors Coffee Lake.

In addition, the Core i5-9400F, unlike the rest of a new generation of Coffee Lake Refresh going on the PCB with thinner the PCB is the same as used for conventional Coffee Lake.

Слева направо: Core i5-8400, Core i5-9400F и Core i5-9600K

From left to right: Core i5-8400, Core i5-9400F and Core i5-9600K

And moreover, even the shape of the heat-spreading lid Core i5-9400F gives the relationship of the Core CPU of the eighth generation. Because purebred Coffee Lake Refresh cover has changed.

Слева направо: Core i5-8400, Core i5-9400F и Core i5-9600K

From left to right: Core i5-8400, Core i5-9400F and Core i5-9600K

In other words, there is no doubt that the Core i5-9400F – in fact, no Coffee Lake Refresh and rejection of previous-generation processors with disabled graphics core. And this applies to all wholly supplied at present, the serial Core i5-9400F that largely explains the wide availability of these processors at a time when the mass supply of Coffee Lake Refresh others continue to experience significant problems. For example, formally announced simultaneously with the Core i5-9400F its “full” counterpart with integrated graphics UHD Graphics 630, which should be based on “fair” crystal stepping P0, in retail sales is still missing.

At the same time, the microprocessor giant doesn’t exclude the possibility of transfer Core i5-9400F on the “right” stepping P0 in the medium term. But it will happen, obviously, only when all accumulated in the warehouses of Coffee Lake with a defective integrated GPU will be successfully sold out.

However, for most users this fact of forgery of silicon crystals is unlikely to have any significance. Anyway, Core i5-9400F real shestiyadernik without support Hyper-Threading, which at any load is running at 100 MHz faster than its predecessor, Core i5-8400. This means that the frequency formula Core i5-9400F corresponds to $10 more expensive Core i5-8500.

Despite the fact that Core i5-9400F claimed comparatively low base frequency of 2.9 GHz, in reality this CPU is able to work much faster thanks to technology Turbo Boost 2.0. If enabled, the Multi-Core Enhancements (that is the default mode for the vast majority of motherboards) under full load, the Core i5-9400F able to keep the frequency of 3.9 GHz accelerating under load on one core to 4.1 GHz.

  Nominal frequency The maximum frequency Turbo Boost 2.0
1 core 2 cores 3 core 4 cores 5 cores 6 cores
Core i5-8400 2.8 GHz 4.0 GHz 3.9 GHz 3.9 GHz 3.9 GHz 3.8 GHz 3.8 GHz
Core i5-8500 3.0 GHz 4,1 GHz 4.0 GHz 4.0 GHz 4.0 GHz 3.9 GHz 3.9 GHz
Core i5-9400(F) 2.9 GHz 4,1 GHz 4.0 GHz 4.0 GHz 4.0 GHz 3.9 GHz 3.9 GHz

No overclocking capabilities in this speech, of course, is not. The most capable Core i5-9400F, for the maximum allowed in the technology Turbo Boost 2.0 frequency. And on motherboards with chipsets H370, B360 or H310 do not get to use and faster than DDR4-2666 memory. More speed modes available only on motherboards with older chipsets Z370 or Z390.
