ill use this thread to collect some new test bioses for the boards, maybe also to explain some less understood options

to disable cores ccd go here and choose ccd xx bit map down core.
each ones stand for an enabled core
best to disable from the back, ie:
instead of 0011000
after selection press downcore apply changes or discard if made mistake


7950x not boosting pass 5.5G -> check that CStates is not disabled
Detailed Explanation on CState Boot Limiter

Test BIOSes:

X3D OC Preset for those MB with asynch BCLK Support: (for simple slight perf boost for X3D)

DOCP/EXPO Tweaked: (for simple timings tightening)

explanation of segment2 Loadline:


customize a heterogenous loadline for a dual segment workload range.

example above shows loadline=L6 when current is in range of 0~40A, and Level4 when current is above 40A.




Adds for x3d

dynamic ccd priority switch with core flex, os / driver agnostic so win10 win11 ok



Algo as follows:
If condition reached and ccd0 specified, then check current mem/cache activity > threshold and hysteresis reached, if fulfilled then switch
If condition reached and ccd1 specified, then check current mem/cache activity <=threshold and hysteresis reached,, if fulfilled then switch
Default hysteresis =4

Can combine multiple algos for ccd priority so combinations are wide

works on non x3d too but of course senseless on it. detailed explanation here.

Hi, I have an issue installing AMD GPIO Driver (for Promontory) Version, seems impossible to install.

Someone else has the same problem ? Possibly solutions ?

Thanks in advance.


It failed on me too, but I can see it in the driver explorer. It was probably already there to begin with

Any reason why this hasn’t made the driver page for the strix -f?  Thanks in advance.

What do you mean? Strix-F page does have 1602 under BIOS & Firmware on Asus page

The beta ROG-CROSSHAIR-X670E-EXTREME-ASUS-1602 and the 1602 version on Asus website have the same hashes. FYI

I just flashed my Strix e-e to newest official bios 1602 and it have worst performance I ever saw.

Settings all the time the same - I tried even load defaults few times and set all values one by one with restart.

Typical settings - expo tweaked, pbo exhancement 80*C and igpu disable.

Every new bios from VSOC problem was slower and slower but this one is a total champion.

On my Extreme I went back to 1516. 1602 the memory overclock with the exact same settings couldn't pass TM5 or Karhu. 1516 is fine though.
