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
octool port to linux
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.

So I'd been running a 7950x on a x670e Hero for a few weeks and was never entirely happy with it; couldn't use CO, low Cinebench (36000)/3DM (14000)/CPUZ (15000/750) scores. I'd tried every setting combination and even learned how to over RAM to see if that was the issue. After feeling deflated and giving up and just staying with lacklustre performance, I bough another 7950x (after the recent price drop) just to see if it was, my motherboard or my CPU. Turns out, it was the CPU. Poor silicon lottery. While the new 7950x is only rated SP116 (old one was SP115), I've got improved performance across the board, caqn actually run CO and have a higher boostclock using the same setting combinations I'd used with my previous 7950x. This was an incredibly annoying discovery tbh, after all the research and hours of testing and fiddling with different BIOS settings, to find out I just had a **** CPU originally.

Out of interest, how is stability if you set RAM speed to 4800 or 3600?

U mean set memory speed on 4800MHz or lower 3600MHz? I try it with 5800MHz with same result 😞 .
I also use the divider at 1:1 maybe I will try to set this position to auto)
but I wouldn't like to change it from 1:1 because then the latency goes up a lot.
