Intel, AMD, VIA & Freescale CPU Microcode Repositories Discussion


Yes, microcode #8 starts at 0x700000 but then gets interrupted at 0x700040 where another microcode (#9) starts:

Something interesting though is that MCE does have a bug. Microcode #9 is fine and shouldn’t have reported that its Reserved fields are non-empty. Turns out there was a variable (re-)initialization issue at Intel & Freescale microcodes which caused that. I’ll consider that an indirect bug report so thank you LOST. I have now fixed it internally so update MCE when the next version is out during the weekend. This is how this corrupted image looks now:

Todays Windows 10 build 18922 includes the same new microcode as the Intel github repo:
!New_cpu206D6_plat6D_ver0000061F_2019-05-21_PRD_990D3CF1.bin

Nothing new for AMD.

I didn’t even inspect, just saw please report so I hoped I found you some little nugget with that non-empty reserved fields
I’ll grab that update once you get it out, thanks. Not sure if this BIOS or the other is one users system needs yet, but if it’s this one I will fix that before sending out to him

What’s first known version of microcode for CPUID=0x40661?
I know only cpu00040661_plat00000032_ver0000000a_date20130502


You can use MCE with -search parameter:


Thx!
Where I can download microcode version 2, 5 and 8 for CPUID=0x40661?

@maks
these are old microcodes with modded headers.

@DeathBringer
So they are home made right? Not original. Well I just find it inside modded bios for my old mobo and MCExtractor said they not in md file.

Nothing new for Windows 10 Insider buid 18941 - I guess they ran out of CPU bugs to fix for the time.
