i7-6400T — QHQG ES CPU INTEL MicroCode Support — BIOS Modding Guides and Problems

Hello I have a misunderstand things for which UEFI-BIOS is supported this i7-6400T. I found one motherboard Asus Z170-A and buy it, will come tomorrow. On other forum overclockers.ru said that BIOS 2202 support stepping Q0. I do compare 2202 and 3202 latest and I found that 506E1 rev1E is not touched till last version 3202, even by UBUtool and same russian site there is newer 506E1 rev2A, that also support Q0-QHQG. With UBUTool I update all microcodes. So my question is will I have some troubles to run this CPU on that Asus Z170-A no matter with which version will come? And will I have trouble with mine updated version?

Are you sure CPUID is 506E1? If yes, then all those BIOS look like they should support it, unless you have info/knowledge that a certain microcode version is required (Older or newer), or certain Intel ME version only.
I think it should be OK with updated, but you never know until you test or find someone else saying they tested. Sometimes you have to use older microcodes, or older Intel ME etc.
If you have issues, you may need 1D microcode, I found these two CPU-z validations using 1D (there is MANY more submissions at HWBot, you’ll have to check them all if you want, and even if they are all using older that may only be because they used old BIOS or date os submission etc)

Thanks for the answer by russian site overclockers.ru I see:
Microcode stepping A0 version 18h — cpu000506E0_plat22_ver00000018_date19-11-2014.bin
Microcode stepping Q0 version 2Ah — cpu000506E1_plat22_ver0000002A_date02-06-2015.bin QHQG is this stepping Q0 and I update this with UBU.
Asus I think they only remove A0 /506E0/ stepping support and for good Q0 will be in tact, the guy that I get my CPU tell me that will need older BIOS, that’s why I ask for that, but his experience is on GigaByte mobo. My research compare all the BIOSES and from first release till last 506E1 is untouched also not updated with 2A, 02-06-2015. So I see that Asus are more friendly to this CPU
first release 0504

For anycase still got one G4400, if things go wrong, but I believe all should be ok.

Yes, often in new BIOS, they sometimes remove the old ES microcodes (Ending in 00, 01, 02 usually) I think you will be OK! If not, yes put in other CPU, then mod BIOS again with other microcode and retest.

I also asks for this in overclockers.ru in russian with google translate.
The answer was that CPU microcode load after start of CPU and in BIOSes above 2202 QO/QHQG/ CPU support is removed and mobo will not power on, I still don’t understand this, but it’s seems CPU support is also coded in BIOS itself and don’t rely on microcode. And maybe this is hardcoded at least for me now

Yes, some BIOS might have other CPU allow/disallow lists that block CPU’s, but not usually. Incorrect Intel ME would make it seem that way possibly, like if only certain version older ME work with the CPU, but new ones block it, then any new BIOS with the newer ME would not start either (even if same old microcode was there).
So in situation where new BIOS does not work with same microcodes of the old BIOS that does work, then you need to check if ME version is same or not, if not make it same as the old one and test again.
Then if that fails, there could be other lists like I mentioned first, but that is rare.
If you check with ME Analyzer, I bet between those versions they say works here these BIOS xxx but does not work here with these new BIOS even with microcode put back to match older BIOS, at that same point you will see a new ME version introduced too.
Example BIOS 1234 with microcode z works, BIOS 12345 with microcode A does not work — so put microcode Z into that BIOS and still fails. I bet at that point in BIOS versions, between 1234 and 12345 Intel ME version was updated, that is the issue, put old Intel ME back into 12345 and same microcode then it works again (usually)
Hope you get what I mean

Thanks again mate, I understand this, that also need to lower IntelME firmware at least as 2202 for my example and then to try 3202, if I want to use newer BIOS with improvements.
Will try it.

You’re welcome. Yes, often older ME may be required, which may require some BIOS wrestling or a flash programmer to get downgraded version if you’re already on a newer version ME.

Intel Core i7 6400T — Engineering processor for the socket 1151
Here it is, Intel Confidential
Content
Budget upgrade opportunities appeared more than once: there was the popular Xeon e5450 and X5460-5470 for lga 775, there was also a rather popular Xeon X34XX line for lga 1156, but no one expected that a modern socket 1151 will someday have a processor comparable in price to i3, and in performance to the current i7.
nine0003
But in 2016 it happened, and the name of this event is Core I7 6400T. Officially, this processor does not exist, you will not find any mention of it on the Intel website. Most likely, the name was given to him by the Chinese, who were the first to start trading on aliexpress and taobao. In fact, this stone is an engineering sample of the Core i7 6700, which has a lower multiplier. Probably, test revisions were massively sent out for testing while Intel was working on the final version of the Core i7 6700, and now everyone can buy and use the i7 6400t. nine0003
Characteristics
There are quite a few versions of SKYLAKE engineers, very different from each other, but not all of them are of interest to us.
The Intel Core i7 6400t supports both ddr4 and ddr3l, but most tests are done on systems with ddr4.
Early models are A0 stepping. They are inexpensive, but very unpredictable.
| Name | Frequency | Stepping | TDP | ||
|---|---|---|---|---|---|
| QH73 | 2. 3 GHz |
A0 | 4 \ 8 | I7 6700K |
It is known that QH8F has problems in the built -in video, but some of the stone is successfully operated by the appearance.
You can try QH8G. There are quite a lot of positive reviews about the work of this revision.
Late models:
| Name | Frequency | 4\8 | I7 6700 | ||
|---|---|---|---|---|---|
| QHJE | 2.6 | Q0 | 65W | 4\8 | I7 6700 |
| QHQF | 2.6 | Q0 | 95W | 4\8 | I7 6700K |
Now the most interesting are QHQG, QHQJ and QHQF, but the latter is almost never found on sale.
Consider the most common QHQG. They are also different, the second part of the marking on the lid indicates the date of issue and is determined as follows: the first number is the year, the next two are the week.
QHQGs come in L452, L448, C445 and L501. It is recommended to take later copies, it is believed that they are chasing better. nine0003
Buying and overclocking engineering samples is, to a certain extent, always a lottery. It is impossible to predict the result
This processor works with an external video card, has a multiplier of 8-26, in turbo boost 28. The overclocking potential is very good, but it depends on a particular instance.
Motherboards for Core i7 6400t
The choice of motherboard for i7 6400t is very important, because not all motherboards will work correctly with the engineer.
For overclocking, use any motherboard based on the Z170 chipset (it will not work on the Z270), but it’s best to take Asrock or Asus, since temperature sensors and AVX instructions work exactly on them. For Asrock motherboards, you will need to flash bios, otherwise you will be left without AVX, you can download it here, it is flashed like any other BIOS for these boards.
nine0003
For Asus boards, do not flash BIOS versions 22** and 3***. With them, the board may not start with an engineering processor.
Owners of motherboards from other manufacturers will have to use the processor without information about its temperature and AVX instructions. Perhaps later this problem will be solved by the appearance of modified bios, but for now Asus and Asrok boards are clearly preferable.
Other chipsets (h210, h270, B150, Q150, Q170) will most likely be able to work with the stone, but only at stock frequencies. Given the cost, which is roughly equal to the i3 6100, using an engineer with budget motherboards may also make sense. nine0003
Overclocking I7 6400t on the example of QHQG
Dependence of temperature on frequency and voltage
Even at the stock frequency, the stone is able to open video cards of the nvidia 970 level, but engineers take it mainly to squeeze out all the juice. In overclocking to 3.
5 — 4 GHz, even the most modern cards, level 1070 and even 1080, will already be revealed. By the way, 4 GHz is not the limit, the most successful specimens are overclocked up to 4.5 GHz.
A table with the parameters of successful overclocking can be found here. nine0003
In general, overclocking algorithm for all motherboards is as follows:
When overclocking on MSI motherboards, you need to disable the Beta Runner function.
-
-
-
- The maximum voltage decided for the processor is set, for example, 1.36v, 1.376v or higher (0.016v step).
- The core multiplier is selected — usually 22 or 24, based on which the BCLK frequency is set, for example 24 × 167 = 4008 MHz at 1.
376v. nine0009
- All power-saving features are turned off to eliminate the impact on stability (they are not always turned off, especially on expensive boards).
- The final memory frequency is either slightly reduced from the nominal on its label, or a voltage is added, for example 1.25-1.3v for DDR-4, to eliminate its effect on overclocking.
- Additional voltages are set: CPU VCCIO Voltage — 1.1-1.2v, System Agent Voltage — 1.1-1.25v, Internal PLL Voltage — 0.9-1v, PCH — 1.05-1.10v, VCC Voltage — 1.1-1.2v — so that the motherboard did not overestimate them at a high frequency of BCLK. Especially often on the machine, it mistakenly overestimates the CPU VCCIO Voltage and the voltage on the processor up to very dangerous 1.7v. Therefore, it is better to put it manually, so calmly. nine0009
- FCLK is set to Auto, or — 400 MHz if the processor frequencies are higher than 3.9 GHz. Asus boards correctly select FCLK on the machine up to 4200 MHz for the processor (I didn’t check it above).
LLC profiles are optionally selected to stabilize the voltage, many set to Auto if the goal is not to squeeze the maximum benefit. On Asus, this is Level 5. On MSI, it may be different or completely absent. - If Windows booted up with the settings set and passed tests, for example, Cinebench, x265 HD benchmark, LinX (with a small task at voltages from 1.36v and with a large one at lower), Prime95, some 3D Mark, and then after a reboot I was able to re-pass some selected tests, so everything is stable. You can start testing in your favorite games or continue overclocking to reduce voltages or to increase the frequency. Ideally, save the settings to the BIOS profile.
- If the tests fail, make mistakes, hang or even Windows does not load, then you need to either add a voltage of 0.016v, or reduce the BCLK frequency by 1-2 MHz and try again. Above 1.39It is not recommended to increase 2v even on a supercooler. And so on, until the tests begin. When a frequency is found where some tests are executed, while others pass somehow, then you can reduce the cache by 1-2 units — up to 22x or 20x, change the memory frequency in any direction, slightly change the main timings, for example, increase their values, again play around with additional voltages within the specified limits, or simply lower the BCLK frequency by 2 MHz and stability will most likely be found.
It’s like in chess — there are only a few pieces, and there are millions of options for their arrangement during the game. But after this engineer, overclocking any other processor will seem like a frivolous, simple game. In a few days of overclocking, Bios will be known much better than in a few weeks of theory and reading articles. Sometimes it takes a long time, because passing the tests takes time. Therefore, the heaviest ones are immediately launched first to speed up the process. nine0004 It is also advisable to monitor the temperature, especially in LinX and Prime, to avoid excessive overheating for a long time.

Successful stress test in acceleration to 4GGC
Example of acceleration at the ASROCK Fatility Z170 Gaming K6 9000
BIOS P7.00 (Twiznut):
this Instruction is not a reference. You do everything at your own peril and risk. Perhaps for your motherboard, memory and processor, you will need to select everything individually.
nine0303
1. Go to CPU Configuration.
2. Set BCLK (system bus frequency) to the value you need (Remember the formula: BCLK x multiplier = processor frequency)
Immediately in the section set parameter Spread Spectrum to Disable . What is it and why can you find it on Google.
Boot performance mode — set to Turbo Performance . This is an energy saver, not needed for overclocking. nine0004 Disabling parameter Intel SpeedStep Technology will prevent the processor from resetting the idle frequency and voltage, which can significantly affect performance and stability. Feel free to disable.
Intel Turbo Boost also does not work during overclocking, so for reinsurance, we’re off.
3. DRam Configuration — RAM setting
We put XMP profile , turn BCLK right there by the same amount with the processor and manually select the frequency that is closest in terms of nominal speed to yours (I have when twisting 193.
125 MHz on the bus, the memory rested at 4.5 GHz). The standard of my memory is 2133, I didn’t want to overclock it, so I set 2124 to Dram frequency .
4. Voltage Configuration
CPU Vcore Voltage set to parameter Fixed Mode . And set the desired voltage for the processor. I started with a value of 1.39 gradually dropped to 1.33. We write this parameter manually opposite the line Fixed Voltage . If you are going to overclock the memory, then the DRam Voltage item can be unscrewed from 1.2 to 1.4. nine0004
5. In the next menu item Advanced
In general, here set the value of the settings approximately like mine. Although it is better to play it safe and google the meaning of each.
Benchmarks and gaming performance
The results are fully consistent with the Core I7 6700 at the same frequency. An overclocked stone can easily load Nvidia 1070-1080, Radeon rx 480-490 and similar video cards.
