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.
I've managed to get my ROG CROSSHAIR X670E EXTREME with R9 7950X and 2x32 G.SKILL 6000MHz CL30 Trident Z5 mostly stable.
I had to use DOCP 2 (DOCP 1 doesn't work) and enabling MCR causes massive amount of memory errors (or no POST).
System posts with following timming, but it takes around 70s (just over a minute) to get to ASUS logo/bios.
On top of that I experience weird issue, where I get a couple of memory errors in memtestx86+ when I jump into it quickly before CPU reaches something like 50*C. It doesn't seems to be just "cold boot" (total power off of the machine) issue as it doesn't happen if I just switch powesupply off for a short time. It also doesn't happen if I wait in bios (for few minutes) before booting memtestx86+. These memory errors happen almost immediately, but after that there are no more errors even after few memtest passes.
This behavior did not change with 805 or 922.
I honestly never seen something like this, any ideas are wellcomed.
