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

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.
Hello,
I have to endure an old issue that is suddently showing up again :
I was perfectly stable for more than a year now, then suddently my system does not POST anymore unless I FULLY shutdown the power supply for at least 6 seconds WHILE THE SYSTEM IS ON.
It does not even work if I turn off from windows, then cut off supply, and reapply...
This happened in the past but was eventually fixed with BIOS update. I was on 1415 until now.
I didn't touched any setting in the BIOS.
I tried to udate to latest (1807) and reapply the settings manually but still same issue...
Why does this issue suddently reappear out of nothing?
And why is there a difference beetween AC off on cold boot?
Is there something that is not properly reset by the BIOS on start so that I need to cut the power supply for the job beeing done as it should be?
Why does it behaves differently if I cut off the AC? Why not just doing the same initization every time?
System :
Strix x670e-F
RAM : 2x KF556C40-32 in slots 2 and 4, DOCP1 (5600)
Timing and voltages that were fully stable for over a year, but now only work if I cut off supply while system is on:
