[Request] GA-870-UD3P BIOS (rev 3.1) with Updated Microcodes

My motherboard has an AM3+ socket (black socket). The problem I’m having is that I can’t use the FX-x3xx processors (Pile Drive) and the microcode 00600F20 is not available in the motherboard bios.

By the way, I followed the tutorial below, added the microcode, but the motherboard does not allow flashing the new BIOS, and even when I flash it with the programmer, the second BIOS is activated because the flashed BIOS file is defective.

Edit by Fernando: Thread title customized

AGESA version maybe an issue here, besides adding the lacking mcode and its an 870, not an 890…
You may try HEX edit directly on the bios image and not on the module, replacing an old one(s) not used, pay attention to size.

EDIT: Sorry, AMD platforms are not for me and AGESA is a module that messes with a lot of other functions, read old threads related to, i remember a thread about bios header edit to bypass the “Invalid” error… not sure if it was for modern UEFI bioses and/or legacy AMI/AWARD hybrid bioses…

In order to test, I removed the hexes related to 00600F12 and replaced it with 00600F20. But I still have a problem. BIOS is not updated by Q-Flash and gives the Invalid BIOS error!

Can you edit AESGA? Because I can’t. I am not professional enough to do such a thing. I really need a bios mod for this board to run the FX-4320 processor on it.

I don’t know if it is related to the BIOS checksum or not!
How to modify or find out the checksum in Gigabyte’s AWARD BIOS?
