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.

Tried 2604 on my X670E-A.
My system shuts off with *any* EXPO setting enabled. The system then POSTs into "safe mode" and clears a bunch of settings. I could do 6400 on 2506, now I can't even hit 6000.
I'm trying to re-flash 2506 now.

Same problem like most people reading this. Flashing back to 2506 is the only option. I tried for 20h all kind of settings and different RAM and bought now an other mobo. Not because 2506 is not stable, but because Asus releasing a BIOS knowing about the problem.

2506 is rock solid on my Strix X670E-F. Standard EXPO profile, 7800X3D.

7800x3d was never a problem. The latency/aida issues affect 9000/x3d.

Not talking about any issues, just adding a general datapoint. Thanks though.

I don't know if you guys saw this, but it could be an explanation for the latency issues:

Basically it says the new BIOS function of "Core Tuning Config for Gaming" introduces wrong data for AIDA.

The test just isn't indicative of true latency in every workload, which has always been the case - but these specific improvements make AIDA's current implementation less accurate. Fixating on one benchmark as an indication of absolute performance has never been the best approach. Perhaps, if anything, this will open people's eyes to testing more objectively when it comes to making changes to alter performance. We're talking about a matter of a few nanoseconds, which is unfathomably small regardless if the test is accurate or not.
