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.

Simple test if a bios is stable or not:
You have to enter the bios and set MEMORY CONTEXT RESTORE from "AUTO" (means "OFF" in real life, it's working like "DISABLED, there is no magic AI in the bios which decides to activate the MCR setting from AUTO to ENABLED...by its own hand) to ENABLED. If your PC is booting correctly after that change (and after min. one PC shutdown), your system might be called stable. The critical phase is the transition from finished bios booting to windows booting which have to be analysed in detail by ASUS and AMD, to find out, why all newer bios' are failing.

MEMORY CONTEXT RESTORE doesn't work with 7950X3D. Many BSOD it's not stable at all. Without MCR - works fine.
