Modded bios Rampage VI

Running rampage VI Extreme original
Which microcode do you find to be better, 49 or 64, and why?
I just upped from your 1603 mod to the 2002 just due to a rebuild and wanted your thoughts.
Thanks for the work!

With the 7000 series, I use microcode 49, designed to have a TJMax of 105° by default
The 9000 series is designed for a TJmax of 110° (default)

The microcodes beyond the 49 heat the cores more on the 7000 series (TJMax which goes from 105 to 110°)

But there is an operating bug with the AVX512, if the frequency is higher than 4200 with microcode 49 (No problem if the AVX512 frequency is lower therefore)

For me, and my opinion

Microcode 49 was release before MDS Vulnerables SA-00233 disclosed and patched.

Microcode 5E which ASUS default 2002 BIOS (RVIE) use was already patched for Intel SA-00233 vulnerables.
For more info :: https://www.intel.com/content/www/us...-sa-00233.html

Microcode 60 and 64 were optimized performance version of 5E.

Microcode 65 was testing for protect aginst

This kind of vulnerability has existed for over 15 years (Spectre, etc...) and it didn't bother anyone before, so I don't care

Thanks, Im running a 9940X so the 64 should be good for me especially running at 4.8GHZ all cores with no AVX offset.

I just remember some time back the 49 gave better temps.

New microcode for Skylake-X and Cascade Lake-X

Skylake-X : 68
Cascade Lake-X : F00

If you want to test (for R6E and R6EE)

์Nice Info master tistou77.These MCU 68 may protect against those error above and these.

Thanks, also regarding your post few days ago where you said quote
"The microcodes beyond the 49 heat the cores more on the 7000 series (TJMax which goes from 105 to 110°)"

Could this be the reason why am getting high temps with my i9 7900x on the Asus Rampage VI Extreme Encore ? My cooling is exactly the same all I did was change the motherboard from Rampage VI Extreme to the Encore and my temps like raised by 7c

Update!!! For Skylake X 65 and 68 MCU Master tistou77


These 02000068 microcode and 02000065 microcode both can be boot at UEFI screen.
However it couldn't boot into UEFI Windows . OLED screen show " DETECT HDD A0 " then
stalled. Roll back to 02000064.

Lastest stable microcode for Intel TSX Abort Asynchronus Vulnerable / SA-00270 was 02000064

Note :: Test both your modded file and my file result were the same. " DETECT HDD A0 " and stalled.

If you went from microcode 49 to a more recent microcode, that's it
If I use a microcode higher than 49, I have the temperature of the cores which increase by about 5° (normal since the TJMax has increased)
