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.

So after pretty non-stop testing on x670e Hero, 7950x, 32gb 6200mhz memory, curve optimizer is completely unusable for me on 0804 bios. Stable with advanced pbo, +200, x10 scale, motherboard limits, cstates on, fclk=memclock, docp 2. But curve optimizer, no matter what negative offset, with eventually cause random resets (usually just before Windows log in).

the +200 wont do much without CO since it wont boost that high without CO. 200 would be 6050mhz fyi
dont use the +limits first as 5850 is plenty high, you want to start off with CO and find the black sheep among the cores -> whoever is failing,
->u can also try percore limits.

I will try this now then and report back later.

do also note that it is not conclusive to surmise the failing core as weak since a good core will be prioritized in usage and will boost higher so it will also be challenging for it to boost even higher.

Just testing all core curve optimizer now with the changes you suggested. -30,-25 and -20 were all no go (reset before Windows login screen), -15 is currently running Aida64 stress test and looks promising (still on 0804 bios)

I had the same issue on my x670e-i. No idea if it is a core on the CPU that can't handle the CO value or just a BIOS/UEFI issue. It may not be an ASUS issue at all, just Zen 4 not having as much headroom with Zen 4. The only way to truly test would be to compare the same chip on different boards.

Seem to be stable with -10 optimizer curve with your advice. -15 Passed Aida64 but then just randomly reset during desktop idling. I'm happy with sticking with -10 for now as I don't have the wherewithall to go core by core lol. Thanks for the help.

Is there any possible way we can get beta updates for the x670e-i? I've noticed some bugs, and among other things, SMU appears to be out of date.
