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.

"3. Improved system performance and fixed various bugs."
As a software developer myself, seeing such a laconic (and pretty much useless) change log entry bothers me to no end...
ASUS, pretty please, be more accurate about what changes go into your BIOS, especially about the "various bugs". As users, we want to know exactly what to expect from a new BIOS: is the bug we were seeing in a former BIOS fixed, or are the fixes of no concern to us (be it because they do not affect our CPU model, RAM or whatnot) ?...
For example, I experienced total system freezes with 2308 and 2401 on my X670E Hero (and reverted to 2204 as a result), and I also reported an issue about the Power Down setting getting screwed up between ASUS' BIOS settings and AMD's ones, but I cannot know if any of these bugs (the first being a show stopper) have been fixed or not...

As long as they don't specify which bugs were "fixed" we can't blame them for not fixing :))
2403 - still can't reboot without randomly getting 0D Q-code stuck in memory training.
Reading the manual, I find it funny because 0C - 0D means "Reserved for future AMI SEC error codes". Very helpful indeed....
Waiting another 1-2 months for X870E-E and if not, I'll be moving to another brand. I'm fed up with this.

Yeah same, having this problem with various bioses since i got my board, just recently started to complain because we maybe we are nearing end-of-life for the boards and nothing actually will get fixed.

Hey. Your problem with random reboot ,I was having the same but i found out by myself a solution for this.You need to change DRAM VDD voltage to 1.4v. After this i never have reboot problem(6 month now). Temps are normal. My default expo profile is 1.35 G.skill 6000mhzCl30 , hynix-a die. My full profile if you want to know is Ram 6000mhz cl 30, DRAM VDD 1.4 , DRAM VDDQ 1.28, CPU VDDIO 1.28, SOC Voltage 1.175v. But if you only change DRAM VDD to 1.4v its enough to work without reboot problem.

Thanks! Just for clarification, I never experienced random reboots. The only problem was that after asking for a reboot it went to a never ending memory training status.
I changed CPU VDDIO / MC Voltage to 1.28v (was running 1.35v), DRAM VDD to 1.4v and DRAM VDDQ to 1.28v. Couple of reboots later: it seems it's working!
I am also running Buildzoid's custom timings and voltages (VDDSOC 1.25v and MC Voltage was set to 1.35v - now 1.28v). UCLK=MEMCLK, Power Down Enable -> Enabled (I read that disabling or even running it on Auto can cause other problems), MCR -> Enabled
Why is your SOC voltage sow low? What CPU are you running?

Couple of questions friend. as you and I have (had) the same issue with infinite-memory training
What BIOS version are you running? is it 2403 as in your signature?
I'm running EXPO II and DRAM VDD & DRAM VDDQ is set to 1.4v by the profile + buildzoids custom timings + UCLK=MEMCLK + PowerDown=on
I also have the same memory kit as you
was DRAM VDDQ also 1.4v set for you as well by the profile?
Are you running any CPU algos? PBO, Curve e.t.c?
I know you might not be able to answer this question but maybe somebody else could point me in the right direction
I'm running 7950X3D and I think I can't go above 1.3v on the CPU SOC Voltage or CPUVDDIO / MC Voltage, cant remember.
In my case should I raise or lower the CPUVDDIO / MC Voltage and why?
10-07-2024 02:39 PM
Hello. Your EXPO profile have DRAM VDD 1.4v?(Maybe 666CZR set ram manually to 1.35v before if he have the same stics as yours) and you have still memory training issues?Then i suggest to disable Memory context and Power down or raise your DRAM VDD to 1.43V. You have the same CPU like me then i can tell you that you can also use this setting as mine. DRAM VDD 1.43(in your case) VDDQ 1.28V, VDDIO/MC 1.28V and SOC to 1.175V. DOnt use CPU algos, PBO is not needed and do not enable option "MEDIUM LOAD BOOST"just instal chipset drivers and must use Windows Balanced power plan, game mode enabled and gamebar updated for X3D CPUs with 2 CCD like 7900x3d and 7950X3d. If you want to undervolt you can only undervolt core 0 1 2 3 4 5 6 7 at negative 15 max.ONLY this CORES!!!.

2403, yes.
And yes it was set to 1.4 by EXPO but then I later also tried Buildzoid's custom timings with 1.35V and those worked better than EXPO, lol. I had the same problem in both cases anyway. It's a miracle it's actually working right now.
Running PBO set to AMD ECO Mode and cTDP 105W
Also running CO -7 all core (didn't have the time to test a lower value)
Not sure about your MC as I'm no longer on a X3D CPU (funny story, all these fixes, including the one for core parking, came 1 year later and a couple of weeks after I switched to 9950X). Try what @Damianos83 said above.
@Damianos83 I'll test a lower VSOC voltage and see if it's still stable. Thank you!

Spoke too soon. Still getting the never ending memory training bug 🤕
I'm now trying with 1.3v instead of 1.28v for VDDIO and VDDQ
Also lowered VDDSOC to 1.2v (from 1.25v).
10-09-2024 01:09 AM
Thank you taking the time posting your settings. I've tested with PBO on/off/enhanced and Eco
Tried DRAM VDDIO / VDDQ 1.4 and 1.35 in different combinations.
Tried both your settings and @Damianos83 settings
Same results, memory boot loop after reboot. System needs hard Power-off in order to reboot.
