Just so that you understand what you are asking for: This is not about activating/unhiding something already there, but to add something that currently does not exist. While it is certainly not impossible, it is waaaaay out of my capabilities to do so. Hence the only other way for me is to find another BIOS that works, which I have failed to do.

Hi
I try a modded bios for my x99h atermiter mobo
Now its just beep 5 time an repeat
I try to identity bios chip but no luck
I use ch341a programer not detect the ic
 so the CH341A can read it. What I did was leave the motherboard alone (remove CPU, RAM, GPU, storage) and only plugging 24pin for motherboard and 8pin for CPU from PSUâŚthen attach CH341a to the BIOS and turn ON PSU switchâŚremember DO NOT turn ON your PC, just PSU. After that CH241aâs red LED will turn on ⌠then you can connect it to laptop to open program and see if the program successfully detecting the BIOS then flash it.

Thank you
I will test it again and back
I try it
I got problem in programer
I got red light and yellow
Not detected in software
I unplug all
Plug 24 and 8 pin from psu conected to power
Put cmos on
Conect programer with ic but no light
Conect programer with laptop its give me red and yellow light
Do i mistake
Oh, man. Sorry!
I had no idea it was so hard.
I totally understand the difficulty you faced, and respect you for that.
In the end, I managed to play BF 6, but Iâm really thinking of upgrading my rig in the begining of '26. Iâm quite sure I wonât face those issues anymore as soon as I do that!
Thanks, anyway! 
Update 2025-09-14
This post is now irrelevant. See this post instead.
Due to the recent requirements of Secure Boot and/or TPM, I have revisited this board. I currently have a X99D3M4 v1.11 in hand for a few more months. To summarize the last few weeks:
- I bought the iEngineer MACHINIST E5-K9 V2.1 CX99DE76 BIOS, but it simply did not boot. Same story with the older CX99DE55 version
- After a lot of BIOS testing (mostly Machinist, Jginyue and Angxun), I have finally gotten the Jginyue X99-TI D4 PLUS BIOS up and running. The only benefit over the other BIOS I have provided in this thread, is that Secure Boot works. Nothing else.
Files can be downloaded from here
Changelog for âFIB_J99TI402_250831.binâ
- Fixed non-working Ethernet and 100 MHz FSB, by transplanting just the Jginyue BIOS region (8M) into my existing X99D4M4 complete BIOS file (16M)
- Fixed the PCIe X4 slot, by setting âIIO 0â to âAuto ; x4x4x4x4 ; Autoâ.
- Secure Boot and Resizeable Bar is enabled by default, by using AMIBCP
- Unlocked RAM timings
- Untested for now since I only have a DDR3 board in hand: Default values should enable CPU overclocking with for instance Throttlestop
- Most importantly: Changed the startup logo
Known bugs
First startup on Failsafe settings is extremely slow. Once you have loaded âSetup Defaultsâ, then the startup time is still slower than before
Next steps
- Solder on pins on the Debug port (I have already verified with a multimeter that they are indeed connected and show typical JLPC values)
- Map the pins, like I showed in this thread

Glad you got BF6 up and running! See above post, after a lot of testing and work, I now have a BIOS that has Secure Boot working. Later on I intend to experiment with adding a TPM module on this board.

Thatâs wonderful news, man!
But this wonât work on a Machinist X99 B9 board, will it?
See previous information in this thread. Simply put: I see no reason why it wouldnât work. But as always, make sure to have a programmer on hand in case there is any problem.

I love to see another X99 warrior in 2025. I currently run a X99 QD4 and a 1660 V3 @4.3GHz all core.
I donât know if itâs okay with the rules of this forum, but would it be okay to ask you about X99 QD4? Have you ever got your hands on one? I tuned my RAM latencies, everything works however the voltage does not increase even though I have set it to 1.4V from the BIOS. It doesnât do anything. Do you think there is a way to fix this issue?
Yeah, I read it. Thing is, I donât have a programmer here with me, so I better wait for someone to try it and, in case of success, Iâll do it too.
Thanks, anyway. I understand how hard it was for you to have a solution and help the community. 
I have not bought any Huananzhi boards, so no experience there. As far as I can tell, only some of the very first high-grade Chinese X99 boards could increase VDDR from BIOS. But once you start to get low enough RAM latency/timings, you get diminishing returns, at least in my own experience (gaming focused). Hardware Canucks had a great video recently, where you can basically slot in your overclocked X99 system somewhere between Ryzen 2xxx and 3xxx (closer to 3xxx). Here is a AMIBCP screenshot of what a finished RAM tweak normally looks like (second hand Samsung ECC RAM). The only thing that is a bit higher than usual is tFAW, due to aggressive automatic tuning of tRRD_L (which in turn forces a high tRRD setting).
If you absolutely need to increase the DDR4 RAM voltage, then I think hardware mods are the only way forward. You can search for âmotherboard volt modâ and prepare to dig and learn a lot.
Hello there! I wanted to ask help if itâs possible. I bought X99D4M4 1.13. Wasnât able to OC my CPU with stock BIOS (I am having 1650v3). I was following your instructions and flashed BIOS with .bin from your first message (3_OC.bin) and it was successful. I changed all settings in bios like in readme and still I canât change anything in ThrottleStop for some reason. Where can be a problem?
Sorry, I fixed it. VMX was enabled in BIOS. After turning it off I can change values.
Wanna give huge thanks for your work tho. I thought I wasted my money on that oard because I somehow missed that it canât OC the CPU. Was sad until I reached that topic. It would be insane to somehow have an option to OC directly from BIOS but even with Throttle itâs already a life saver. I have 4.4 OC on my 1650v3 now.
As I see itâs still impossible to somehow make D4M4 to OC CPU directly from BIOS? I really need VMX enabled but itâs killing Throttle cuz because of virtualization it canât access cores voltage.
Glad you figured it out. These days many low-level software does not work once you start increasing security settings. So as a first step you can try other software instead of Throttlestop, like for instance: Intel XTU ; Universal x86 Tuning Utility etc
If you check the Bilibili link in the first post, there is good information and some interesting files as well. In particular, the file âX9MRSmod-Microcode.româ did not boot on my X99D4M4. But it did on my ZX-99EV3 and CPU overclocking from BIOS did indeed work. So in other words: If you have time and energy, you can probably use UEFITool to transplant/swap some files into the X99D4M4 BIOS, to make OC work from the BIOS. Not a priority for me, a software solution is âgood enoughâ for my purposes.
PS: Did you click on âLoad Setup Defaultsâ after you flashed the OC BIOS? If so, then there should be no need to change anything manually.
Thank you for the answer, I will try another software!
I donât have anything like CH341A and in general I donât really understand what even to swap, ahah. It was achievement for me to make a backup of my stock BIOS via fpt. If you ever will have a time or something to make it work I will be really grateful, because I am searching anything to make the virtualization work without killing overclocking but still no luck 
And yeah, I did reset BIOS after that and everything was tuned up, but VMX was still turned on for some reason.
P.S. Ordered CH341A but still donât know how to make a thing about BIOS ahaha.
A little update: Software not working. I turned on VMX and turned off Hyper-V component and Throttle is still able to OC my CPU. But still I need Hyper-V, sadly.
If you do get your hands on a CH341A, you can now get both Secure Boot and TPM working. See more details in this post

Oh, my!! Thanks for the info.
I looked up here and found some CH341A on sale. They ainât expensive, though.
Iâll study a little further how to do the process and changes and decide whether itâs worth risking my rig here. You can call me a chicken but this is the only one Iâve got.
Thanks, anyway!! 
Hello, how to fix Unknown USB Device (Link in Compliance Mode) i am flashed your bios 3.88 MB file on MEGA in https://www.jingshait.com/products-detail/id-310.html works perfect, Thanks
Official Stock bios X99 D4 DUAL PRO mega.nz/file/EJUFhLiY#V4Pf3ws4xC6QH43yIB_qELzu1KLcG9m1qrNBXVL_DAE
Since I do not know the answer to this, I will give you an idea how I would approach it:
- Option 1: Is everything that you need to work, already working in an acceptable way? If yes, you can just ignore this exclamation mark/disable the device. You can also try updating the driver via Windows update, it might do the trick
- Option 2: If this USB something device is absolutely needed, then I would start by checking the IIO:s for both CPUs and make them the same as in your original BIOS. See IntelRCSetup/IIO/IIO x/. Due to the enormous amount of NVME disks on your motherboard, I am very sure you anyhow need to double check this. This may or may not fix the USB problem. But be aware that due to potential hardware differences this may be a very, very deep rabbit hole.
- Option 3: Not likely, but maybe the settings I put in with AMIBCP are the cause of this problem. You can hence try the stock BIOS. And if you happen to have 26xx V3 CPUs, then you can even go with the TBU (Turbo Boost Unlocked) version they provide.
