Curious problem - Officially non-existent BIOS version on my motherboard?!

[Rukjor]

Hello all,
 

I need help from experts again. First of all, English is not my native language, so please excuse my grammar. Thank you.

I use the following mainboard:
"P8H67-M PRO/V-P8H67E/DP_MB"
from Asus
 

I swapped the Pentium for an i7 3770 and could not boot because I forgot to update the bios.

So I downloaded BIOS 3904 from ASUS. But now I get the message "Image Integrity Check failed".
I have tried several versions, everywhere the same problem.
 

Then I noticed that my motherboard has version "1301" installed. But this is not listed at ASUS (?!?).
 

Then I noticed that there seem to be different versions of the P8H67-M PRO.
One with 6 SATA ports + 1x IDE and one version with 5x SATA and no IDE (which I have).
But I can't find a BIOS for it.

See Pictures attached. I have "Version 2".
 

Do you have any idea??? Thank you very much!

 

Andy

UPDATE: I just found out, that this Mainboard is originally from an OEM System "CM6850".

https://www.asus.com/us/supportonly/CM6850/HelpDesk_BIOS/

In this case it looks like I can't update the Mainboard any further.
Right?

Well, I will leave this topic online, as I might not be the only one with this confusing problem.

It has a socketed bios chip so you can use a cheap bios programmer like ch341a to flash the bios

 

Btw those boards should have a bclk setting so you can set to ~105 to give a lil boost to performance

Thank you! I will try this.

If the Board does not boot, I can just put back in the "old" Bios Chip, right?

No just reflash with said bios programmer to your old bios
