Okay guys,so i test so many cpu microcodes for SKYLAKE-X 50654 for X299 systems,the best for perfomance and overclocking and better thermals is 0200002B you can mod your bios with this cpu microcode!!i found with my 7960X at 4.7GHZ stable on 1.18v and higher scores!!so maybe help someone to go with LN2 scores!!!

For me the latest microcode 02007206 perform better than 0200002B a lot on WIndows 26H1
Safe from Spectre and meltdown attack running great with latest Windows 11 26H1 above .

i tested so much about these cpu microcodes and nop your microcode is way worse than 2B all test on Cinebench r15 r23 and another good is 2B microcode has less heat!!!

I had tested an old microcode, and my RAM overclocking wouldn't work anymore (it wouldn't boot, but it worked if I lowered the frequency). Maybe it needs more voltage.
I re put the latest MCU 😊

@tistou77 you have 10XXX series?

Yes, with an older MCU, I lowered the RAM frequency and was able to test it.
A small performance gain and less CPU heat (the TJMax is modified with this MCU, if I remember correctly).

Same here - boot error.

@Cherry_PL_ you have cascadeLake-X?

Let's playing games with safety first . Performance impact on new microcode didn't much more to concern. However older microcode maybe faster a little bit but higher risk too.
