@R1ce_Puppy - can I borrow your skills, and some of your time?
I have another BIOS with this same error using AMIBCP 4.55, but even removing entire amitse module does not resolve so I don't think it's in that module.
I already search using UEFITool for 04 39 00 00 00 39 and .9...9 with no results, I also extracted SUBGUID at AMITSE, PE32, and SetupData there and search each for those via hex, no luck.

So, I wondered if maybe you'd spare some time if you can and help me find the issue with this BIOS. I need to edit some defaults in AMIBCP (NVRAM) that don't take effect by editing setup module.
So I assume once we find the issue I can temp remove that module, or edit it so it opens in AMIBCP lets me make my edits, then I can replace original issue module back when done.
Hope you have some free time and don't mind taking a look, I'd really appreciate it, thanks!

@Blissed @R1ce_Puppy - see this post, newer version fixes this issue for me on several BIOS already, and fixes those BIOS where you see German or other language or garbage text for names etc
Unlock Aptio V Z170 Board Menu Chipset unhide and other Menu

My motherboard is HUANANZHI X99-8M
Because the official website does not provide a BIOS for users to download
The attached BIOS is obtained after I communicated with the online customer service staff.
I used AMIBCP 4.55 and 5.02 and will display the same error message.

I saw this article has the same problem as me. https://www.win-raid.com/t3859f16-Error-AMIBCP-language-name-present-exceeds-x-in-lenght.html
But it seems that there is no solution :(
Thank you again for your help.

@jordanpchome - the only answers for this are provided in the thread you linked, and any fix is BIOS specific (what fixes on one BIOS only fixes on that BIOS, not all)
I've moved your post to that thread since no need for two threads on same topic.

What is it you are wanting to do with your BIOS, I can probably help you without AMIBCP

I want to turn off the C6 function of the processor because this option is not available in the BIOS.
Also turn off CSM, preset to open FASTBOOT

@jordanpchome - I went to check to make sure this error always appears in all versions, and it doesn't! So you can use AMIBCP 5.02.0031, sorry I didn't think to check this before, I assumed you already did
So mod can be done there, make settings visible too if you want, or just change defaults. If setting access level to User or Supervisor on the settings you want doesn't make them visible, let me know which ones and I will fix for you (probably need unsuppressed in setup module, or may require full BIOS unlock)


If you can't find, send me a PM

This is my negligence. I forgot to look for the latest version of AMIBCP. Thank you very much.

Another question, because I have an FFS file using e5 v3 all core turbo
What is the difference between the two C6 options in the picture? Other discussion articles suggest that I close C6

But I don't know which option is better. :(

I do not know what this means >> FFS file using e5 v3 all core turbo
As for the two C6 states, I do not know either, since you can't use C6 it doesn't matter anyway. I have no clue about any of that, sorry, you'll have to ask more about this where you find these articles you mentioned.

You can refer to this discussion:
[GUIDE] Haswell-E/EP Xeon CPUID:306F2 Turbo Unlock

Even if I open the hidden menu, I still can't find the location where the BIOS can set the BLCK :(

Bclk? That has nothing to do with C6 settings. You're loosing me here
Do you mean you need me to find the Bclk setting for you in the BIOS and make it visible? I checked, and this is not an option in this BIOS, so you can only change Bclk by editing ME FW in the ICC zero profile using Intel FITc program
That or you can add new profile, set one that is OC type profile, then change BIOS to use this profile instead of zero - all a lot of work to change bclk, and would need redone each time for any new bclk you want to use, not an ideal thing to be doing really,

As for the discussion, thanks for info, but it's not something I need to learn about as I do not have these CPU's or concerns with C6 stuff, you'll have to ask those users who mess with that what they suggest you choose as your setting.
In my mind, you said your CPU does not support C6, so easy to decide I think, one of the other options other than C6 since you can't use it
