I will ask again because I have a different BIOS version than 1.27, I have 1.51 installed
downloaded from this page:
https://www.catalog.update.microsoft.com/Search.aspx?q=UEFI\RES_{12b99262-648c-4365-bafd-eb869fb72094}
does pla10 and platC0 change with the bios update??
I mean that 806E9 as C0 (6,7) is the same as for version 1.27 and for 1.51
Intel is running the CPUID 806E9 concurrently on two different platforms:
806E9_C0 = Kaby Lake-U (socket BGA 1356)
806E9_10 = Amber Lake-Y (socket BGA 1515)
You know that you have a Kaby Lake-U processor (i5-7200U) so your only option is to use C0 which is what is in the BIOS you linked for v1.51.
Microcode versions released after B4 will have a performance penalty as Intel attempted to add more security patches - personally I wouldn’t worry about updating it to the latest.
@chinobino
I’ll ask again because as I remember, the BIOS update for my laptop model from 1.27 to 1.51 always had the processor microcode version B4. Can switching from B4 to F6 cause anything other than a drop in performance, for example with the BIOS? I’m asking because I’ve never done it and I recently discovered VMware CPU Microcode Update Driver, which as @THEBOSS wrote, can be updated without having to tinker with the BIOS. You also added that “personally I wouldn’t worry about updating to the latest version.” So I understand that the B4 microcode version that is in the BIOS is safe and ok.
@martin4562 You can update to F6 if you want to, the performance decrease is determined by workloads that use specific instructions e.g. The Downfall exploit (CVE-2022-40982) effects SGX which is enabled on many Intel machines by default. According to Intel:
Intel® SGX is designed to protect data in use with isolation, encryption, and attestation capabilities to help guard against threats while also allowing users to maintain control of and use of their data.
Tom’s hardware wrote an article about Intel’s Downfall mitigations suggesting that:
there’s a potential claimed performance impact of up to 50% on AVX2 and AVX-512 workloads involving the Gather instruction.
The problem with using the VMware CPU Microcode Update Driver:
The big issue with the VMWare solution is that currently the OS mitigations are not enabled. On boot, the kernel is started and does a CPUID check. The BIOS microcode is loaded at this point, and fails the HW mitigation check, and the OS disables the support. THEN the VMWare driver is loaded.
We would need to see if we can force the OS level support to be enabled in conjunction with the VMWare driver loaded.
So while the newer microcode is ‘running’ the OS mitigations aren’t, which defeats the whole purpose of updating the microcode for increased security.
I can understand why THEBOSS would want the latest microcode for their 13th Gen system as the microcode effects CPU voltage but for older CPUs this method may not be practical.
Hope this helps.
If you want… I can help provide you the latest micrcode available for your CPU specifically if you want. Just let me know and I will send it you. 
Hi @jen11. In Jan 24, you posted cpu506E3_plat36_ver000000F2_2023-01-02_PRD_86DC342B on this post.
I’m trying to cross-reference that MC, and I’m only being pointed back here. Can you let us know where that one came from? I’m updating an older Dell with an i5 6500 CPU.
Thanks

It’s possible that the version F2 is a repackaged DC. Looking for cpu506E3_plat36_ver000000F0_2021-11-12_PRD_D39CBFD5. I’ll check it and will follow up when found.
Edit 2: I found F0

I think F0 needs to be the latest, and F2 discarded.

I must have extracted my current DC microcode and saved it as cpu506E3_plat36_ver000000F2_2023-01-02_PRD_86DC342B.bin.
Edit 4: I don’t know how long it takes Intel to officially post updated microcodes on their Github site, but this is what I’m seeing now:
and …
I’ll be applying the F0 microcode until I get good info on the F2.
The file attached below contains the “F0” microcodes from the Intel and platomav Github sites, and they are hex editor identical.
Ver F0 and 06-5e-03.zip (214.4 KB)
EDIT 5: The F2 microcode is being covered by Dell under their OptiPlex 5050 System BIOS.
Hi, added r306

@chinobino has made a new REPO, as you may already know, where all the mcodes are organized by folders, so grab the damm mcodes from @plutomaniac REPO, download them to the correct folders by CPUID, simply as that.
Can we know whats YOUR issue in doing this, for adding a couple of mcodes to your own archive???
r307 added.
@MeatWar
I do this so that @chinobino is updating his archive always good (it’s trigger for him when there is a new update, see it as positive). chinobino archive got also old microcodes as well which I sometime use, which @plutomaniac doesn’t have anymore because they are superseeded. I don’t download all the microcodes from plutomaniac site, because this site exists which got most of the microcodes. To trigger chinobino I post in this topic, it is not off-topic. I post when there is a update and it is not often.
A post was merged into an existing topic: MC Extractor: Intel, AMD, VIA & Freescale Microcode Extraction Tool Discussion
