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:
110000
instead of 0011000
after selection press downcore apply changes or discard if made mistake
ocpak/octools
FAQ:
7950x not boosting pass 5.5G -> check that CStates is not disabled
Detailed Explanation on CState Boot Limiter
Test BIOSes:
new:
X3D OC Preset for those MB with asynch BCLK Support: (for simple slight perf boost for X3D)
DOCP/EXPO Tweaked: (for simple timings tightening)
strixe-e 1515
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.
Solved! Go to Solution.

Hey Shamino,
is there any newer Test Bios other than the 0902 (https://www.overclock.net/threads/asus-rog-crosshair-x670e-overclocking-discussion-thread.1799959/po...) available?
That one has weird CPU Boost Behaviour on my Hero and 7900x
CCD2 is suddenly Boosting higher than CCD1, at least the effective clocks shown in hwinfo for example
I also face random Freezes/Bluescreens with 0902
Do you know what changes are there from 1003 to 1004?
Currently i am running 0805 which is so far the best Bios

I too experience the blue screen instability on 0902 on my 7950X. I also agree that 0805 is by far the most stable yet.

Has anyone who has tried the beta/test BIOS after 0805 found it removes the c-state limiter which limits the boost speed?

It's there in 902 on my X670E-E Strix, though I haven't tried it in 902 because in 805 it would severely limit CO values and lower boosts overall. The only thing it seemed to help with for me is seeing higher max boost numbers in HWInfo at the cost of idle stability and real overall performance.
Editing here a few days later...
Per a recommendation, from someone on OCN, if you experience instability with Medium Load BoostIt (which is the option that disabled the C-State limiter), you can use Per-Core Boost Limit to manually limit individual cores and tame the instability. It's just as time-consuming as figuring out your per-core CO values, but essentially a must if you want to disable the C-State limiter.

Hi, iam New an i have a Problem with strix-e and ryzen 9 7900x. Its Freezing sometimes in idle Mode. Under load all is fine.
What can i do, please help. Iam on 0805 bios.
Thanks

Have you made any adjustments to your Precision Boost Overdrive or Curve Optimizer values? Also, do you have Medium Load BoostIt enabled?
