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

FAQ:
7950x not boosting pass 5.5G -> check that CStates is not disabled
Detailed Explanation on CState Boot Limiter
Test BIOSes:
Spoiler
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.
@gupsterg As you might remember, I previously mentioned that I couldn’t get tRP 37 stable with GDM Disabled. After updating to AGESA 1.2.0.3g, I was finally able to make this profile stable by applying the following settings:
Nitro TxDFE Gain Bias P0 [DFE Gain Bias Step 0]
Nitro RxDFE Gain Bias [DFE Gain Bias Step 1]
Currently, I’m running 1.74 VDD 1.6 VDDQ 1.45 VDDIO and it passes VT3 without errors, and I’m seeing 256.5 MB/s bandwidth in Karhu. Previously, anything above 1.5 VDDQ would cause errors, so these Bias settings seem to have helped a lot.
What are your thoughts on this? Since applying these Bias adjustments, both tRP 37 and 1.6 VDDQ have become completely stable. Thanks for your help!
