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.
Solved! Go to Solution.

Gskill 6000mhz c30 EXPO kits.
now i am running 6400 C30--38-38-20 ,trefi 65535 aida64 read and write at 90000MB/S,latency 57ns.
the setting is on 0803bios ,if you use 0805 bios ,voltage will be low ,MC,VDDQ and VDD at 1.48v,soc auto

I ran memtest86 throughout the night. Less than 6 hours in, the testing completed without issue. Seems my problems are almost certainly not memory related. It's probably BIOS and/or vBIOS related.
I'm running 4x dimms of G.Skill F5-6000J3038F16G at 6000 Mhz on the Asus Crosshair x670 Extreme.
Now that I've been running it for a while... My box is a lot more stable with 0805. Occasionally, my GPU will still occasionally "fall off the bus" (but definitely less frequently), however, it hasn't once happened when not gaming, which is a huge improvement for the stability and general non-gaming usability of my box.
Still no vbios updates for my GPU.
So my feedback is that 0805 is working a lot better than even 0803 (which worked as well as 0705) at least for me. Looking forward to testing the next BIOS update!

Another problem is when i use 0803 bios ,i set fclk at 2166mhz,mem at 6400mhz ,uclk will be 3250mhz,it 's unusual.
And,if i want fclk at 2166mhz/2200mhz to be stable,i need to misc voltage to 1.45V,SOC volatge to be 1.45V.(sometimes it's also unstable)

Not sure since which Bios or already all the time like this, but as far as I know everyone has this behaviour from UCLK depending on FCLK.
So I assume its AGESA related since not Motherboard (Vendor) / BIOS dependant.
But it gives also more performance, so to me it seems like if you have for example 6200 Memclock and 2100 FCLK then you are somehow running like 6300/3150/2100. Therefore you need less tight timings/more voltage for it to be stable.
Here is my discovery:
