@NeXT Thanks again.

Does anyone know what CPUID's 106A0 and 106A1 are?

Has anyone actually seen one in the wild?

It looks like Intel has unified the microcode patches for Skylake (506E3), Kaby Lake (806E9, 906E9), Whiskey Lake (806EB, 806EC) and Coffee Lake (906EA, 906EB, 906EC, 906ED) as of 5th Jan 2021 with ver000000EA.

Are there any microcodes for Rocketlake available yet ?

@jhonnypolak Sure, I have added the following;

Socket 1200 (LGA)

A0670 Rocket Lake-S ES (A0)

@chinobino Awesome ! Thank you so much !

Wonder if anyone found some differences with the EA ucode, I've been using for a week on a 8700K or so and it's on par with the rest of the later ucodes, slightly decreased performance and everything.
Last "normal" post Spectre mitigations ucode was B4 for me.

@jen1 Hi, I am currently running with the earliest microcode for 9900KS (CPUID 906ED) which is AA.

If I get some time I will try to test EA to compare the difference, very busy IRL at the moment.

Sorry how to upgrade microcode cpu R0 stepping D 9900KF to bios msi z390 Ace thanks the best for voltage please

@forzic17 If you are using ritizen's modified MEG Z390 ACE BIOS with microcode BE for the R0 revision of the 9900KF (CPUID 906ED) then you likely have the best performing microcode with lowest voltage according to Toppc on chiphell.

I am using the oldest microcode (AA) on my 9900KS R0 (also CPUID 906ED) but I haven't had time to test against later microcodes but I can say that this chip only needs v1.293 V maximum to hit 5GHz all core with no AVX offset and no temperature throttling, which my 9900K P0 could never do.

But does the bios published by Ritizen's already have the microcode in question on or can you give me your modified one?

@forzic17 Ritizen's modified BIOS has these microcodes;



If you want to download more microcodes to test with your CPU then check the first post in this thread --> [OFFER] Intel CPU Microcode Archives

I have added a new folder for socket 1377 (BGA);

Marvin tipped me off to these 23 new microcodes (thanks @Marvin);

Mate!!! @chinobino!!! you test newer cpu microcodes vs Oldest one??do you see diffrence on perfomance???i think oldest is better perfomance always
