@chinobino Some more microcodes:

cpu106A4_plat03_ver00000010_2009-02-20_PRD_020495E7.bin
cpu106A5_plat03_ver0000000F_2009-02-20_PRD_81EF718C.bin

Extracted from the official P6T-ASUS-DELUXE-2209.ROM BIOS.

Also, for the reference, this BIOS contains some PRE microcodes:

cpu106A0_plat03_verFFFF001A_2007-11-28_PRE_8A7F71A8.bin
cpu106A1_plat03_verFFFF000B_2008-02-20_PRE_1060D521.bin

@NeXT Thanks again.

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

Has anyone actually seen one in the wild?

77

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.

78


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.

79

Are there any microcodes for Rocketlake available yet ?

80

@jhonnypolak Sure, I have added the following;

@chinobino Awesome ! Thank you so much !

Did you enable all the mitigation? Can you provide Get-SpeculationControlSettings result?

For my CPU I noticed a huge increase in the performance.

@jen11 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.

84

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

85

@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.

86

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

87

@forzic17 Ritizen’s modified BIOS has these microcodes;

MSI MEG Z390 ACE 7B12v1B1 Mod v1.png

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

91

@panosxidis Hi, usually I do test new microcodes out but I haven’t been able to lately. My landlord died and I was evicted as new owner wants to sell (so all my belongings are in storage). Had to move an hours drive out of the city as no rentals available etc…

92

im so sorry

93



Didn’t see any difference in cpu-z/aida benchmarks with 906E9 (7700K) compared to previous one

94

Mate take the Oldest one on your cpu 7700K and repeat the test!!! @DCCentR
