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.

I also have (had) this issue. Tried with G-Skill cl30 6000 Mhz 64Gb Intel, and the same model but 32Gb Amd Empo.
Same problem.
For me, it might be related to Curved Optimizer I guess, I now run Intel with only PBO on and so far ok. But you never know, because the random boots are just random 🙂

any ram with expo should be qualified right? i've seen some type from Corsair and gskill, not much of them support by the board (mine is Strix X670E-F) , at least according to the manual.

I have the same motherboard as you and replaced the previous kits with this ones -> G.Skill Z5 Neo F5-6000J3636F16GX2-TZ5N. EXPO 1 runs perfect now. Im not that much of a overclocker and just want to put expo on and go on doing my things.

I've been having trouble getting my memory to run stable at 6000mhz on my X670E Crosshair Hero.
I specifically went for a 6000Mhz CL30 for the best performance and picked up an EXPO kit thinking it would give me the least trouble. However, even on 0805 it doesn't even boot when I switch EXPO on.
RAM is G.Skill F5-6000J3038F16GX2-TZ5NR
I've not tried with the latest chipset drivers, I'm about to do that to see if it makes a difference but I am not hopeful. Without EXPO enabled, the RAM is solidly stable at stock speeds.
I've tried reading back through this thread to see if there was some other option or setting in the BIOS I might have missed. I haven't done much tinkering or enabled PBO or anything like that, I've seen some settings mentioned but I can't find them. Anyone with the same RAM kit having any joy?
Also am I missing anything - I just go into AMD overclocking and select "EXPO" from the dropdown and that's it?
Also: Wake-on-LAN seems broken on 0805. I have otherwise no networking troubles running at 2.5G speeds (plugged into an SFP+ adapter in my switch), but despite WOL being enabled in both the BIOS and Device Manager, as well as fast boot being disabled, it doesn't want to work. It worked on an older BIOS.
