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
octool port to linux
7950x not boosting pass 5.5G -> check that CStates is not disabled
Detailed Explanation on CState Boot Limiter
X3D OC Preset for those MB with asynch BCLK Support: (for simple slight perf boost for X3D)
DOCP/EXPO Tweaked: (for simple timings tightening)
for crosshair and strix e-e:
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.

Itâ€™s funny that itâ€™s been a couple days now and a few people have commented that 0922 is causing problems on otherwise stable systems and ASUS have gone radio silent on the matter.
I have always bought ASUS kit where possible but I am really disappointed in how AM5 has gone so far, initially I was willing to give the benefit of doubt given it was a new platform but we are past that and I am not sure we should be still be having these kinds of issues.
Despite what has been said about the c-state limiter, I am still not convinced it is working as intended on my board because I never see anything abov 5.5Ghz even on single core workloads
I've had 2 random reboots and 1 random shutdown in 24h. ROG Strix x670e-e gaming BIOS 0922. No error on event manager. No custom PBO curve applied, just PBO enabled. Tried to disable C-States but no luck.
I had random reboots with no blue screen or event logs other than the unexpected shutdown message. For me it was either too low of an offset in curve optimizer or too high IF clock. I am still trying to figure out which it was.
I've been sitting back and waiting for more info to come out about 0922 and I guess I'll try it this evening after work.
So far, 0805 has been stable but I like to tinker...
Running X670E Hero and 7950X with GSkill 32gb DDR5 kit F5-6000J3038F16GX2-TZ5NR.
Will report back either way once I get time to mess with it.
Updated to 0922 with zero issues. EXPO I enabled and UCLK=MEMCLK set to 1. No cold boot issues, no BSOD yet. Benchmarked a few times. All seems well so far. Will update as it goes.
I wish I could figure out the reason why mine was so unstable at cold boot. I didn't set UCLK=MEMCLK to 1 though. Maybe that was it?
