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.
Solved! Go to Solution.
On the side of boot times, I have swapped 7950X3D for another 7950X3D (SP went up from 109 to 117). Cold Start to Windows in 16 seconds (EXPO, MCR, PBO all on) on 1415.
Question for the rest of the group. OC menu has certain OC Profiles available (X3D and gaming) that boost base clock to 4.33.
Has anyone tested if voltages are still in check long term? Different workloads data would have been helpful.
I'm with DDavid, CO-curve + async eclk is the way, other than that keep temps low, keep unnecessary voltages low and necessary high and some PBO slight tweaking is what is left.
Oh, and off course memory OC, it's the main OC with Zen 4 for a minimal performance uplift
I'm for tweaking down voltages, set temp limit and ppt limit to be able to not need a custom loop and keep nice and quiet for 24/7 usage
1415 is very unstable for me, 1410 beta was the most stable ive used. Seems like the 1415 doesn't like any kind of manual voltage settings. 1415 wouldn't post with same settings as 1410, so i reverted and setup all of my settings and am back to 30-38-38-68 6200 1.4vram/soc1.3/
I've been running SOC at 1.1V and VDDIO 1.1V before CPU started exploding and never had problem booting with any bios version was stable on 1202 and currently at 1415 and still stable so far (1 day of gaming use).
I run gskill 6000MHz CL 30 XMP on 1.1V SOC and undervolted RAM from 1.4V to 1.35V. Maybe I'm just lucky SOC owner?
Are the 4 stick sets like this (CORSAIR Vengeance RGB 192GB (4 x 48GB) 288-Pin PC RAM DDR5 5200 (PC5 41600) Desktop Memory Model CMK...) supposed to be working at the declared speed? Otherwise it's just nothing but false advertizing?
"Intel XMP", they may run at advertised speed on an Intel rig, doesn't say anything about AMD
These are validated on Intel platform given they show for XMP and not EXPO. You could probably get them to work with the latest Bios that support high density ram kits.
Seems like someone on reddit done some testing and found EXPO to work but needed some voltage boost.
Level1Tech just posted a video today about high density kits on Ryzen, maybe worth a watch.
