ASRock just updated the BIOS for my Z97E-ITX/ac and I noticed that they inserted a new CPU Microcode but I have no idea what platform it's for.

This is what MMTool shows:



The other three are for Haswell desktop retail and ES SKUs but the first one has a totally different platform type and CPU ID.

For some reason MMTool crashes when I try to open the Microcodes tab with that BIOS.

Since the thread, where you had posted this info, has been designed just for the UBU Tool Guide and the News written by SoniX, I have moved it into this already existing thread about the CPU Microcodes.

Please posts about the CPU microcode to move here.
Done!
Thanks for your info and advice. I haven't realized, that jetflow's post had nothing to do with the VBIOS modules.

hello, i have an issue adding a microcode to P7P55D-EVO bios. i extracted the latest microcode of the i7 860 (cpuid 106E5) from the latest microcode.dat and verified the file with the intelmicrocodelist.exe file (output: CPUID=106E5 Rev=07 2013/08/20 CRC=C6783666 Off=0 Size=1C00 Plat=0,1,4) then i tried to replace the old microcode with mmtool 3.26 but it says the microcode file is invalid. then i exctracted the current microcode and run a verification on it (CPUID=106E5 Rev=04 2010/04/05 CRC=F7762473 Off=0 Size=1800 Plat=0,1,4) then i found out that the sizes differ.

the most recent microcode looks okay to me since i can add it with the uefi mmtool to an uefi bios.

any suggestions?

i included the exctracted / the recent and the bios file.

I wanted to revert back to Ivy Bridge microcode 19 on my Gigabyte z77x-up7 (3770K) from 1B. The bios says it is back at 19 but HWiNFO64 and AIDA64 say its still on 1B.




Are the programs showing the wrong value? I reverted the microcode using UBUv1.18.

@ johns36j
Look CPU microcode version in the BIOS settings. If there is value 19, then the version 1B puts the OS Windows.

The CPU Microcode is layed down within the BIOS and has nothing to do with the in-use Operating Systems.

@ Fernando
There must be something wrong with my system because in the BIOS it states I have microcode 19 but HWiNFO64 is reporting 1B and AIDA64 is reporting 1Bh.

Only one of them can be right. I think it is the BIOS.

I have never flashed bios with 1B microcode, always 19 or older, but HWinfo shows 1B. Asus maximus v gene & 3570k.

A tool like HWinfo can only show, what it is coded to look for, no matter if it is correct.
Example: The Device Manager shows the driver date of all on-board Controllers, but it doesn't even check the driver itself. It just reads the associated .INF (=text) file. So if you change the driver date entry by editing the INF file yourself, the Device Manage will show that date and not the correct driver date, which only can be verified by right clicking onto the driver itself (= .SYS file) and choosing "Properties" > "Details".
