What memory should be preferred for systems based on processors Skylake or Broadwell-E – the question is not idle. The introduction of DDR4 SDRAM opened to the industry, many opportunities, and manufacturers of memory, which is obviously bored with the long stagnation with DDR3, launched a fierce competition aimed at the conquest of new frontiers of bandwidth. The result is a paradoxical situation, when Intel considers standard memory types for their processors, DDR4-1866 and DDR4-2133, and on the shelves you can find deals twice as higher speeds of DDR4-4266. But the best option of memory for modern PCs powered by the latest processors, you probably want to look somewhere in the middle.

As we know from the results of previous tests, in General increasing the frequency of the memory affects performance too much. The throughput of any dual-channel memory DDR4 for most applications in General enough. Therefore, a noticeable difference can be seen only in two situations: either in applications that are actively working with large volumes of data, or by increasing the frequency of memory not one but several steps. In other words, even if we are talking about the variety of memory modules for high performance systems, it is logical to look in the direction of the high-speed option available, and such a set of modules, which offers an attractive balance of volume, working frequency and rates. Moreover, in most cases, DDR4-memory “average” can be disperse later.

In order to assess the current state of the retail market of DDR4 memory, we have analyzed the prices of the dual channel kits with capacities of 16 GB. If, for example, to focus on the range of the largest North American store the picture turns out like this:

The difference in price between the slow and the extremely fast sets of more than three-fold. But the most rapid growth of value begins only after the mark of DDR4-3000. Therefore, the best options for mass users have the kits level up to DDR4-3000 and the memory class DDR4-3200 can be recommended for enthusiasts of high performance. Using the same particularly high-speed modules with frequencies of about 4 GHz – lot of radical overclockers and experimenters. The kits not only unnecessarily expensive, but also require a certain amount of violence against the CPU memory controller that with prolonged use can even lead to the exit of the CPU down.

Actually, the structure of the range itself gives a hint of what DDR4 can be considered the optimal choice. Thus, the most a wide range of memory kits presented today in categories DDR4-2400 and DDR4-3000. And in the second place by the number of sentences – DDR4-2133 and DDR4-3200 SDRAM.

In this situation it is not surprising that many manufacturers of memory for enthusiasts refuse to release an extremely high speed sets. Our range of offers-level DDR4-4000 and higher speed can boast only the most ambitious of the manufacturers of memory – G. Skill and Corsair. The majority of their competitors do not consider it necessary to supply the memory with frequencies higher than DDR4-3600, and many of them do limited release of modules with a frequency of 3.0-3.2 GHz, which is the steady mass demand. And that testing such a memory, we plan to focus in the near future.

In this review we will focus on a dual-channel 16 GB kit DDR4-3200, which gave us the company Patriot Memory. This firm has been producing quality memory for over 30 years. And despite the fact that around the name of Patriot is no such marketing hype, such as around Kingston or G. Skill, its products for decades, offer an excellent combination of performance and price. Today the assortment of Patriot there are different sets of DDR4 with frequency up to 3.6 GHz, but for testing we received not the high-speed option. The manufacturer decided that the best way to reveal all the advantages of its current line of memory class DDR4-3200. And partly we are ready to agree with him, but all in good time.

#Patriot Viper 4 PV416G320C6K: detailed introduction

The range of DDR4 memory company Patriot includes two lines: the Viper 4 and Viper Elite. Honestly, the fundamental differences between the characteristics of the sets included in these series, we did not notice. In fact, the Viper Elite series is interesting due to its peculiar radiators, which are available in three different colors – red, blue and gray. But the Viper 4 series is wider by item and are rapidly growing. So in this review we will focus on the set of modules DDR4-3200 is from the Viper series 4 – PV416G320C6K. Kit with this article includes a couple of modules 8 GB each and is positioned by the manufacturer as fully compatible with the latest Intel platforms: LGA1151 and LGA2011-3.


All these basic information given on the packaging of the kit, which is a cardboard box with a transparent window through which is visible one of the modules. Inside the box the memory blocks are additionally enclosed in a Styrofoam form, which serves as an additional protection against damage during transportation. Any package is missing, in addition to the modules offered only a sticker with the logo of the Viper brand under which the company produces not only Patriot memory modules, and various gaming peripherals.

Against the background of what the radiators were installed for their overclocking memory modules with some other manufacturers, the appearance of representatives of the Viper series 4 is not too spectacular. However, the system heat sink, applied the Patriot, is not as simple as it seems at first glance. The fact that it consists not of two but of three parts: two black aluminum if it fails plates, which are sandwiched between the printed circuit Board with chips and screwed them on top of the red comb-like radiator. All three parts are painted by means of anodizing, and on both surfaces of the modules are glued decorative black and maroon sticker with white lettering “Viper”. The result is a bit grim, but such modules normally fit into the modern gaming system components for which are usually performed in black and red color scheme.

Many memory kits for overclockers too are equipped with large radiators, the dimensions of which create problems during Assembly of the computer. However, the developers Patriot has you covered. The altitude of the Viper 4 the fee is quite decent 41 mm, but if some of the modules won’t fit under the CPU cooler, it is possible to remove red radiator comb. It is attached with two screws, and after dismantling the height of the modules is reduced to 33 mm.

So the source of the problem can be unless the thickness of the cooling system. Due to the fact that if it fails, the plate is massive enough, the thickness of the module Assembly is 8.5 mm, and on some motherboards with closefitting DIMM slots for memory modules Viper 4 may not fit next to each other.

If you look at the photo above, it seems that at the bottom of the fins away from the chips. But in fact it is not. Just for the plates on the chips used thick strip of elastic heat-conducting material. So when you compress them on top of additional radiator comb they naturally bulged downward but are tight to the memory chips.

On one side of the modules Patriot Viper 4 PV416G320C6K you can see the label. It is possible to glean some information about the specifications of the kit – its composition and volume, the target bandwidth and the CAS latency. However, this is not comprehensive information. A complete list of characteristics reported by Patriot exclusively on its website. For the considered set PV416G320C6K it looks like this:

  • series: Viper 4;
  • number of modules: 2 module 8 GB;
  • rated frequency: 3200 MHz;
  • latency (tCL-tRCD-tRP-tRAS): 16-16-16-36;
  • working voltage: 1.35 V;
  • XMP support: Yes, XMP 2.0.

That is, we have quite a regular overclocking DDR4 memory average. As follows from the specifications, the mode DDR4-3200 is achieved by sampling the chips, but also increase the operating voltage up to 1.35 V with a simultaneous weakening of the scheme delays. However, unlike many other such kits, Patriot managed to avoid the overstatement tRCD and tRP timings. This clearly indicates that the use of such modules, chips manufactured by SK Hynix. In order not to unnecessarily escalate the affair, immediately look under the radiator.


And here we are waiting for is not the bad news. Set PV416G320C6K compiled on the basis of Samsung chips K4A4G085WD-BCPB. It is quite old, but very popular among overclockers chetyrehskatnye IC Samsung D-die, which can be found in the modules, designed for speeds up to DDR4-3600. Itself Samsung klassificeret them as DDR4-2133 scheme delays 15-15-15, but in practice increasing the voltage they show good scalability on the frequency of operation.

As for the Board on which chips are mounted, it is made from regular green PCB, which is in the overclocking black and red straps memory looks not just foreign, and, one might even say, ridiculous. However, that is a simple explanation. The marking on the PCB clearly indicates that it is also manufactured by Samsung. Moreover, a similar design and element base of DDR4 SDRAM are not only Patriot, but in the range of very Samsung. In other words, it seems that the Patriot does not collect your overclocking modules independently of pre-selected circuits, and buys from Samsung are completely ready memory modules, and then disperse them.

In support of this theory, you can refer to the fact that to find an analogue to the Patriot Viper 4 PV416G320C6K, but no heatsink and no guarantee of performance at a frequency of 3200 MHz is not too difficult. It’s called Samsung M378A1G43DB0-CPB00 and widely sold under the guise of a regular 8 GB DDR4-2133.

Модули Samsung M378A1G43DB0-CPB00 – полуфабрикат для Patriot Viper 4

Modules Samsung M378A1G43DB0-CPB00 – prefabricated for Patriot Viper 4

However, you need to understand that the differences in modules Patriot Viper 4 from the original Samsung memory is not only in appearance. In addition to checking and any selection of the most successful planks engineers Patriot stitch in your overclocking kits XMP profiles 2.0, which simplifies their configuration in modes with increased frequency.

Recorded in the SPD kit, Viper 4 PV416G320C6K mode DDR4-2133 with delays 15-15-15-35 corresponds to the nominal characteristics of the donor chips and modules Samsung. The profile XMP 2.0 is the regime, the performance of the kit which promises the company Patriot. In full compliance with the stated specifications in this profile describes the parameters for the frequency DDR4-3200: voltage 1.35 V and timings 16-16-16-36 scheme.

The relationship of a set of Patriot Viper 4 PV416G320C6K with the usual DDR4 SDRAM under the Samsung brand impact not only on the content of the SPD. In addition, unlike other overclocking memory modules Patriot do not have temperature sensors. This, of course, can hardly be regarded as a critical shortage, but we must bear in mind that most of the modules DDR4-oriented audience of enthusiasts, its own temperature to keep still know how.

Nevertheless, other attributes of the considered high-speed memory kit, Patriot Viper 4 inherent. So, for a claimed lifetime warranty and full compatibility with modern interesnimi platforms on the basis of sets of logic Intel X99 and Z170. Moreover, according to the manufacturer’s website, all overclocking kits of Patriot are required to undergo premarket testing manual.

The Intel Core i3-9350KF: ashamed to have four cores in 2019

With the advent of the processors generations of Coffee Lake Coffee Lake and Refresh by Intel, following the lead of a competitor, is systematically studied with increasing number of computational cores in their proposals. The result of this process was the fact that in the mass of the platform LGA1151v2 formed a new OCTA-core chip family of Core i9, and the family of Core i3, Core i5 and Core i7 has significantly increased its Arsenal of compute cores. Less fortunate series Core i5: processors, Quad-core former in the past, eventually became shestidennomu. But today’s Core i7 processors feature eight and Core i3 processors – four cores, making them twice as attractive in comparison with the predecessors, offered just two years ago.

About how well developed the evolution of the senior consumer Intel processors, we have already recounted, when tested new fosmidomycin Core i7-9700K and Core i9-9900K, as well as new six-core Core i5-9600K. However, the representative of the family of Core i3, belongs to a generation of Coffee Lake Refresh, we have not discussed. Many of you probably think that it should be, because at first glance, the transition from design to Coffee Lake Coffee Lake Refresh Core i3 series never happened: the processors of the tenth thousands offer exactly the same four cores without support Hyper-Threading as their predecessors. And it seems that no significant difference in performance and consumer qualities between them. But not so simple.

The fact that a new series of Core i3, in contrast, for example, Core i5, yet it was clearly better. And it’s not in the growth of clock frequencies, which, judging by face value, has not increased at all. Most importantly, what happened to Core i3 new generation — they support Turbo Boost technology 2.0, which still remained the prerogative of the processors series Core i5, i7 and i9. The result is a real working frequency of fresh Core i3 increased significantly, making the first representative of the updated series in the face Core i3-9350KF noticeably faster offer compared to the older Quad-generation Coffee Lake, Core i3-8350K.

    Kaby Lake (2017) Coffee Lake (2018) Coffee Lake Refresh
Core i9 The number of cores     8
L3 cache MB     16
Hyper-Threading     +
Turbo Boost 2.0     +
Core i7 The number of cores 4 6 8
L3 cache MB 8 12 12
Hyper-Threading + +
Turbo Boost 2.0 + + +
Core i5 The number of cores 4 6 6
L3 cache MB 6 9 9
Turbo Boost 2.0 + + +
Core i3 The number of cores 2 4 4
L3 cache MB 3-4 6-8 6-8
Hyper-Threading +
Turbo Boost 2.0 +

Thus, today’s processors Core i3 become full heirs of the members of the series Core i5 generation Kaby Lake: they have exactly the same set of basic capabilities, and the clock frequency at least as good. And that means Core i3-9350KF with a price of $173 allows you to performance even better than the provided Core i5-7600Kthat cost (and, incidentally, continues to cost, according to the official price list) $242.

However, according to popular belief, the formation of which took an active part in the first place fans of AMD with four cores today are suitable only for office computers and modern games supposedly require the CPU more developed multithreading support. Where did this judgment is not difficult to guess: AMD price range from $150 to $200 today do you can offer not only six, and even eight cores with SMT support. But that doesn’t make Quad Core i3-9350KF absolutely worthless and a priori, not worthy of attention.

In order for arguments to decide whether the right to existence of the Quad surrounded by rivals heavyweights, we conducted a special test. In this review we will answer the questions buyers have when dealing with the modern Core i3. That is, check whether the Core i3-9350KF to compete in the actual games and how its performance looks at the background of the performance of AMD CPU that you can buy in the same price category.

#Core i3-9350KF in detail

When meeting with Core i3-9350KF and then there is the feeling that somewhere in all this we have already seen. It is not surprising. More recently roughly the same characteristics of the processors was proposed in a series of Core i5 and new Core i3-9350KF really like some Core i5-6600K or Core i5-7600K. Since Intel switched to the 14-nm process technology in the desktop segment, no micro-architectural improvements, the processors do not undergo, and therefore between Skylake and today’s Coffee Lake Refresh there identity equality in terms of IPC (the number of executable per clock cycle instructions). Thus the Core i3-9350KF, as well as its ancient predecessors series Core i5 has four cores, does not support Hyper-Threading technology, but has technology avtoradgona Turbo Boost 2.0.

But the Core i3-9350KF even better than the previous Core i5. First, the capacity of the cache memory of the third level in the processor is 8 MB, that is, each core is allocated 2 MB, while the Intel Core i5 generations to Coffee Lake for each core relied only 1.5 MB of L3 cache. Secondly, Core i3-9350KF, which produced a third version of the 14-nm process technology, could reach substantially higher clock frequencies. So, it has a nominal frequency defined by the interval of 4.0-4.6 GHz, and Core i5-7600K maximum frequency in turbo mode accounted for only 4.2 GHz.

Thus in reality even at full load on all cores Core i3-9350KF able to hold its frequency at around 4.4 GHz.

Load on one core allows you to display the frequency on the promised specification 4.6 GHz.

The intermediate frequency is 4.5 GHz, you can see that if the load is on 2 or 3 cores.

It is understood that, formally, the specified frequency of the processor holds in that case, if its power consumption does not go beyond 91 W – the boundary defined by the characteristics of the TDP. But in fact, motherboard manufacturers have not pay attention on such trifle as a heat pack. The Multi-Core Enhancements, which eliminates the energy monitoring on modern motherboards is enabled by default. However, in fairness it should be noted that specifically at Core i3-9350KF even at maximum load work using AVX2 instructions (Annex Prime95 29.6) power consumption is about 80 watts. In other words, the declared TDP Core i3-9350KF fit without any restrictions on working frequencies.

In the family of processors Core thousandth series Core i3-9350KF is the only product belonging to the class Core i3. Although officially it was also announced on other models, including the Core i3-9350K, Core i3-9320 Core i3-9300 Core i3-9100 and Core i3-9100F, sales, as well as in the official price list, they have not yet appeared.

Why is it so easy to understand: the explanation suggests the letter F at the end of the reporting processor. It means that this CPU is deprived of the integrated graphics core, allowing Intel to use for its production of defective crystals that were not able to get into serial Core i3 before. Indeed, stepping Core i3-9350KF – B0, this means that the basis of such processors on the same silicon crystal, used in the composition of the Core i3 series eight. In other words, the Core i3-9350KF – twin brother Core i3-8350K without integrated graphics Graphics 630 UHD, but enhanced with Turbo Boost technology 2.0. Moreover, these processors have not even vary the nominal frequency, so that the entire gain of the product is provided exclusively turbo, which, however, in this case, fairly aggressive and is able to accelerate the work of the CPU by 10-15 %.

For clarity, we give a table which compares the characteristics of the Core i3-9350KF and actively mentioned by us like processor previous generations Core i3-8350K and Core i5-7600:

Core i3-9350KF Core i3-8350K Core i5-7600K
Code name Coffee Lake Refresh Coffee Lake Kaby Lake
Production technology 14++ nm 14++ nm 14+ nm
Socket LGA1151v2 LGA1151v2 LGA1151v1
Cores/Threads 4/4 4/4 4/4
Base frequency, GHz 4,0 4,0 3,8
Maximum frequency in turbo mode, GHz 4,6 4,2
L3 cache MB 8 8 6
TDP, watts 91 91 91
Memory support DDR4-2400 DDR4-2400 DDR4-2400
PCI Express 3.0 16 16 16
Graphics core No UHD Graphics 630 HD Graphics 630
Price (official) $173 $168 $242

It remains to add that the Core i3-9350KF as Core i3-8350K, refers to the number of proposals overclocking Intel. Its multiplier is not locked, which allows you to freely change its motherboards based on chipsets Z370 and Z390.


No reason to expect Core i3-9350KF any significant acceleration there. Don’t forget: at the heart of such CPU are semiconductor crystals of the old B0 stepping, and not selected, and Vice versa — rejection with broken graphics. In other words, the Core i3-9350KF waste from the production of Core i3-8350K, and, based on this logic, the novelty is unlikely to accelerate better than Quad core overclocking CPUs present in the market so far.

A practical test largely confirmed this assumption. When setting the voltage at 1.25 V Core i3-9350KF was able to work steadily at a frequency of 4.8 GHz. Increasing this voltage to 1,275 In the situation with the maximum frequency did not improve, and at a voltage of 1.3 V we had to deal with CPU overheating at high AVX2-load.

By the way, here the negative role played and the fact that the Core i3-9350KF architectural refers to the generation of Coffee Lake Coffee Lake and not Refresh. Newer processors have learned to push the temperature that turns on the throttle, up to 115 degrees. But with Core i3-9350KF is impossible: for him to say only heat to 100 degrees. In addition, will have to forget about the solder between the heat-spreading lid and the chip in Core i3-9350KF is polymer thermal interface, that is thermal grease.

Thus, if we judge by our instance CPU, then overclocking the senior Quad without the use of special cooling methods can be overclocked by about 10% relative to the nominal mode. And this relatively low increase in operating frequency is unlikely to help them fundamentally improve productivity. In other words, as in the case of other Core processors thousandth of the series, overclocking continues slowly over here. With the release of new generations of CPU limits overclocking is almost relegated, but the nominal frequency each year increased quite markedly, each time stronger and stronger narrowing overclockers.

Our website is one of the few online resources in the Russian segment, which still pays attention to motherboards and has been tested on latest devices all present on our market for the producers. However, by going to the “motherboard” 3DNews, we will see that the last review of the motherboard form factor mATX, which you can use to build a really powerful gaming PC, came out in early 2017. Such payment to and acceleration was all right, and with reliability and functionality. Basically, if we are talking about reviews, in the test lab hosted ATX and mini-ITX solutions are the current trend. Meanwhile, there are Micro-ATX case, which is quite suitable for the solution of the given task — they are well-organized cooling and they are able to accommodate powerful hardware. Thing is, it turns out, for small: need payment — and one of the few options left will be ASUS ROG MAXIMUS GENE XI. About all the pros and cons of the device read in this review.

  • one extension cable to connect the RGB strip;
  • the additional screws to install the SSD;
  • Q-connector for easy connection of buttons of the housing;
  • ROG DIMM module.2, support the installation of two SSD.

#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.





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

Samsung J7 V just $5 mo. New device payment purchase req'd. Plus, free shipping.

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

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.
