X670 resource


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

Test BIOSes:

X3D OC Preset for those MB with asynch BCLK Support: (for simple slight perf boost for X3D)

DOCP/EXPO Tweaked: (for simple timings tightening)

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.

Apologies for being off topic, but how did you manage to achieve such a high read score? I have a stable 2x16GB Corsair Dominator Titanium Kit and they are nowhere as close. Any suggestions are very appreciated.

Setup is a 7950X3D on an X670E GENE



That's sick bro, wp. Any soggestions why my read is slow?

EDIT: Update - Fixed the issue by disabling SVM. Man, it's actually crazy how much performance memory integrity / virtual encapsulation costs.


activate nitro and increase fclk. F9 for searching, and typing "ddr5"

activating nitro just affect when you have 8000+mhz ?
and what is the nitro settings u do

It depends, if your timings are very tight, then it is possible that you will experience instabilities when using NITRO.

no i mean what this settings do increase stability, performance what?

I'll post all my BIOS settings for memory including Nitro when I get home from work in eight hours or so.

All my 1905 memory BIOS related settings. You CANNOT do Action on BIST Failure 'Do Nothing' on newest BIOS, and these settings NOT stable on newest BIOS, only 1905.

Don't forget at the bottom of IMGUR to load ALL the images, not all of them show by default.

And with these settings, there is a bug, you need to set the settings, save profile to Profile 1, then save all the Settings to USB, reboot, load the settings from USB, reboot again, then finally load the Profile 1.

If you don't, you'll get a double boot, your RAM will be stuck at 5200 until you load BIOS defaults, reboot, then repeat all these steps.
