[Guide] Overclock BIOS mods for Chinese X99 MBs

I cant find bios flash fir 16mb

All its just 8mb my mobo is x99e v 1.2

Chatgpt said its not full dump or the programmer cant flash all 16 mb when using clip

Have you made a BIOS backup and got the hardware programmer (CH341A for example) at hand? Can you reflash the stock BIOS to revive the board first? Your motherboard is based on chipset HM55 with Intel ME v6 so it’s pretty likely that following exactly the guide in here wouldn’t work.

I reflash the backup but not working

I use mi89 app for backup

@Arabicdec48 That’s strange. How do you reflash the backup?

Using ch341a with clip

All ai i ask tel me that normally the bios is 16 mb

But i found just for 8 mb

@Arabicdec48 yup, the 8MB bios is incomplete (might be missing the ME Region). Is your backup from Mi899 only 8MB? Can you upload it in here?

X99P3007.zip (3.0 MB)
Ok can you try flashing this BIOS? It’s from Angxun X99-P3 v9.01 (same HM55 chipset as your board). See if the board could be revived first.

Hello. Can you please tell me how to install ME 9.1.37.1000 instead of SPS v3. The BIOS is from JGINYUE X99-8D4/2.5G Server zx-x99d4m 1.21?

What do you mean by install? Do you mean that you want to use the BIOS from Jginyue (comes with SPS by default) on your ZX motherboard? If that’s the case then just replace the BIOS Region in your stock BIOS by the BIOS region from Jginyue board using UEFITool 0.28 and flash to see if it works. Make sure you have a hardware programmer and working stock BIOS dump to recover.

I only replaced the ME Region the other way around. Was that my mistake? The system went into a permanent reboot.

I’m not sure how exactly the two methods differ but I have had some failures replacing the ME Region before, so I figured replacing the BIOS region is the way to go.

Thanks. I’ll try, maybe I’ll get lucky. Poor programmer. :slight_smile:

I recently did exactly this for test purposes with the latest Huananzhi AD3 BIOS on my test system

  • I just transplanted the 8M BIOS region into an existing complete 16M BIOS I had from before. But sadly I could not get CPU overclocking working from the BIOS (still needing Throttlestop)
  • And if you find FITC for SPS 3.1, please let me know. I had no luck a few weeks back

Assuming that the descriptor and BIOS region has the needed flash support, you can of course just swap the ME region and test. Just pay attention that sizes must match exactly, as I had to do in this post with the X99-K9 ME region (ā€œFFā€ padded up to the right size)

I got it working. It booted on the second try (waited 5 minutes). JGINYUE X99-8D4/2.5G Server ME 9.1.37.1000, zx-x99d4m 1.21 board. UefiTool 0.28 alone was unsuccessful; the board kept rebooting. Rebuilding with Fitc 9.1.10.1000 worked. Has anyone tried installing a higher ME version on c610/c612 chips?

@**ForeignerInBeijing**Thank you for your work. I stumbled upon your thread. However, there was no Debug desoldering, so I had to learn how to use a soldering iron. I also couldn’t find tools for SPS v3.1.

It takes a long time to turn on, about a minute to wait until the logo appears, then it hangs for another 20 seconds on A2. Is there a solution?

I don’t know what motherboard you have (especially flash chip), or especially what you are trying to achieve here. But if I were you:

  • I would firstly try with the BD4 based BIOS I made in this post. It is by far the most functional X99 BIOS I have come across
  • Only if you have problems (especially XMC flash chip), then you can look at other options in this post

zx-x99d4m 1.21 2024 Bios ver 0.06 XMCQH128C. I tried the b2 black screen from your post, b1 constant restart (I haven’t tried the stock one). Can you tell me about ME 9.1.40.1000? It tells me that the Flash image tool 9.1.41.3024 even exists? If that doesn’t help, I’ll install the JGINYUE X99-8D4/2.5G. It works perfectly. I’ll have to keep looking for tools for SPS, which is unlikely. I want it to be compatible with the BIOS from the JGINYUE X99-8D4/2.5G and ME.

What exactly do you want to do with the ME Region? Have you tried to just swap the BIOS Region of stock BIOS with JGINYUE’s one? I don’t think a newer ME version would be significantly different tho.
