You did it wrong now.
Do it this again - https://www.bios-mods.com/forum/Thread-X...#pid171249
Without Set Multiplier & Turn On
If it doesn't help the try slightly different.

Run RWEverything and go to Access->Command
Type commands:
wrmsr 0x1a0 0x0 0x840081
wrmsr 0x199 0x0 0x1000
Go to ThrottleStop's folder and delete file ThrottleStop.ini and run ThrottleStop.
Run TS Bench and make screenshot when it's not complete yet.

Ok I did right this time. result seems to be same.

[DeathBringer]

OK. Do now slightly different variant with 2 commands only - https://www.bios-mods.com/forum/Thread-X...#pid171284

Then run RWEverything again.
Press CPU MSR registers button, press User list button or F5, type g=0x19a, press Add, press Done.
Post a screenshot with results.

here the results

Seems this processor is doomed. I am beginning to feel like there is no way unlock this freq cap.

[DeathBringer]

It's bad.
The last change is old version of BIOS.

Stop! MSR with address 0x1a0 is not equal 0x840081!
Redo it again.

[ahasan]

I am going to try all the old versions of bios. I will send you the results soon.

[ahasan]

I have changed it to 0x840081 but its the same.

[DeathBringer]

OK. But SpeedStep is disabled now.
I wait for your results with old versions of BIOS.
You need after each BIOS flashing to patch FpgaSocketConfig - https://www.bios-mods.com/forum/Thread-X...#pid171074
and SocketPowerManagementConfig - https://www.bios-mods.com/forum/Thread-X...#pid171137

for any other who wonder why 6126F don't work on that X11DPT-PS.
Supermicro has dropped OmniPath Fabric support on boards manufatured after juli 2018.
In the F type processor are two DIE, the CPU-DIE and the Fabric controller-DIE(Intel Corporation Omni-Path HFI Silicon 100 Series)
The Fabric controller (CD=companion die) is not powered anymore.
If you try a F CPU on a non supporting mboard you will get the following issue:
does not work at all.
one or both CPUs, were running at 700MHz or lower.
