@chinobino Awesome ! Thank you so much !

Wonder if anyone found some differences with the EA ucode, Iā€™ve been using for a week on a 8700K or so and itā€™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.



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.

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 ritizenā€™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 havenā€™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 Ritizenā€™s already have the microcode in question on or can you give me your modified one?

87

@forzic17 Ritizenā€™s modified BIOS has these microcodes;

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 havenā€™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 etcā€¦

92

im so sorry

93



Didnā€™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

95

TIL that at some point Intel disabled TSX in many 14nm CPUā€™s. I only checked using microcode DE and later on my 9900KS (CPUID 906ED) but it may be patched out in even earlier microcodes;

Microcode AA (TSX Enabled) = Windows 10 with mcupdate_GenuineIntel.dll disabled

9900KS AA mcode TSX.png



Microcode DE (TSX Disabled) = Windows 11 with mcupdate_GenuineIntel.dll enabled

9900KS DE to EC mcode no TSX.png



[Edit] I stand corrected, as ritizen has pointed out;

96

You are use the oldest one on your 9900K? @chinobino

97

Hi @panosxidis , yeah I am using the oldest for P0 revision, which is 84 and for R0 revision AA.

98

Iā€™m on the EA ucode for my 8700K and TSX is still enabled. EA was the latest until the last round of Win 11 ucodes. Unsure I wanna bother with the EC one yet.

The new microcode of Skylake (506E3) has not come out yet. However, it does not seem to be better than ā€œone version of the pastā€. ā€œThat versionā€ may be a special version. I think that the new version is not necessarily good like this. This is an personal opinion.(ā€œThat versionā€ is also added worth to part other than ā€œprocess performance side and security sideā€. In the later version, the added worth part is likely to disappear. Process performance is probably almost the same as the previous version and later version. Thatā€™s why. (Results by personal testing.)) For TSX, ā€œThat versionā€ is ā€œENABLEā€ in the case of me.(It does not mean that TSX is related.)

my opinion and my experience on X99 and X299 platforms the OLDEST cpu microcode gives better perfomance so that it!!!
