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
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.
Solved! Go to Solution.
Still no luck on 1002. POST on default but after making changes I only got one boot. Tried EXPO, EXPO II, EXPO tweaked, turning Memory Power Down to enabled. I got some other Q-Codes with EXPO Tweaker like 0d and a freeze on 1A where I couldn't even reboot.
Tried removing HDDs and Gen-z.2 board, and reseating memory again.
Back on 0805 memory is still good, EXPO worked fine and I'm still managing to lower times there for fun with no errors.
sounds strange, can you try advanced memory voltages/synch all pmics/memory vpp voltage set to 1.85v (default 1.80v)
(high dram voltage mode = auto i presume? )
