You're welcome! I'm not sure what MMTool version you're using, that link is for a microcode
Extract the codes from the BIOS I sent, they all work with MMTool, downloaded ones may not as some might have been size adjusted for MMTool. I can't remember which I did yesterday, last one for sure but possibly 2 others too
But if those from my BIOS fail for you too it MMTool version issue, use another version of MMTool if the one you are using gives that error with codes extracted from the BIOS I uploaded. Microdoes are already adjusted in that BIOS for MMTool when version is correct
With the codes extracted from my BIOS give error on insert, then try other version 3.19 or 3.22 or 3.26. With downloaded microcodes you may get that error on several of the codes due to MMTool has sizing requirements for microcodes sometimes.
If all else fails, upload your modified BIOS here and I will put in the new microcodes
