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.

I'm still stuck on 0805 with the Crosshair Extreme and 32x2 G.Skill 30-40-40-96. Wish 0088 or 1001 would POST right for me. Sitting on installing a 7950x3d and MSI MEG1300ai until I find out if it's a bad mobo AND BIOS issus or just BIOS issue. I keep lowering my memory timings and voltages on 0805 and it still runs rock solid for me but anything 1.0.0.5c(or later) is a POST disaster once EXPO is on.

You seem to be having all the bad luck.
Do you have any issues with the newer BIOSes when EXPO is off and entering timings manually?
At this stage I'm wondering if there's something up with the EXPO SPD on your memory and 0805 isn't reading it properly so it just defaults to something workable, while the newer BIOSes might be reading it properly and attempting to apply settings that don't work.

Was testing the MCR with power down and it was working fine for almost a week. An then it stopped. Windows stuck on boot. Only MCR disabling helped.
