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:
instead of 0011000
after selection press downcore apply changes or discard if made mistake
7950x not boosting pass 5.5G -> check that CStates is not disabled
Detailed Explanation on CState Boot Limiter
X3D OC Preset for those MB with asynch BCLK Support: (for simple slight perf boost for X3D)
DOCP/EXPO Tweaked: (for simple timings tightening)
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.

Here is EXPO on in 0805
Here is reduced timings and volatge, fclk=2000,uclk=memclk on 0805(still stable).
Not sure if it matters but I in the 22.214.171.124c and above BIOS I start to see tPHYRDL not match between the two sticks. (One of the rare 0088 boots)
I entered most of the timings there and set fclk=2000,uclk=memclk.
decimus28, did you test enabling (from default AUTO=OFF to ENABLED) POWER DOWN ENABLED mode in DRAM TIMINGS CONTROL settings concerning your problem?
In general activating The GEAR DOWN / POWER DOWN ENABLING command helps the DDR4/5 memory to ensure better system compability."
What part of "test bioses" do you not understand.
It's the same issue with release 0922, the tests and betas(upto 1001 at least). Same results with nothing but EXPO turned on from default. The manual timings shown there for 0088 was because I was asked if RAM spd might be reading wrong for one or the other so I matched them to working 0805 settings and out of all of them I caught 0088 on a successful POST. I'm sure your've seen from my other post this isn't a test BIOS only issue.
Strix X670E-I Owner here ever since I updated to BIOS 1222 and Installed a 7950X3D my USB has been randomly disconnecting. I have tried what others have suggested including turning off power management to all USB Hubs in device manager to no avail. I have also tried BIOS 1220 and 1221 same issue on both. Also whenever I flash the bios it will fail on the first attempt to post (stuck on orange light) I have to manually pull the power from the PSU and then will Post normally after a long wait afterwards...
Rolled back to 0822 on which my 7700X was running fine, 7950X3D still having usb disconnect issues. Also had unchecked power off for usb controllers as well as hubs. Even tried moving some of my higher powered usb devices over to a powered USB hub. I have also tried disabling one ccd. Still no change.
