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.

What CPU are you using?



Level 10

I've updated to the 1101 Bios.

Still getting hard locks. Black screen, fans ramp to 100%, and can't reset unless the PSU is turned off then on again.

USB dropouts increased. I have had my keyboard drop out a few times as well as my camera.

Audio popping is still present in the new bios as well.

1410 from x670e-i very stable but not get +5.5ghz 7950x

Level 8

Hi @Shamino 

Any chance you could have a look at voltage regulation or sensor reporting? Because something is way off, either the voltage supplied or the value that the sensor reads. My board is a Strix B650-A (BIOS 1406), but everyone I know with an Asus AM5 board has the same issue.

VDDIO / MC manually set at 1.35, both BIOS and HWINFO report 1.376V with some spikes to 1.392V under load. More of the same for VSOC and other voltages.

Any clue? I know that it's not a top priority seeing the various stability issues still persisting with some boards, but it would be nice if you could have a look.

Hello all, im looking for the Boost Curve tool. I was told it was supposed to be in the ROG X670E  ocpak/octools  DB Query > AMD V/F > Get Boost Curve.

When I download the zip i dont see DB query >amd v/f Ge boose curve. i think maybe im being dumb. 

Found it 

Hi, I've got a strix x670e-a but can't find async bclk mode or x3d oc presets either in bios 1004 and 1101. Please help.

Level 7

I'm using ProArt X670e Creator now

After watching some overclocking videos, I found a feature called asynchronous BCLK to be very useful. From what I've researched, this feature seems to be implemented on some ROG motherboards.

Any chance this interesting feature will be supported on this motherboard in the future?

The Same Here 

I have a Rog Strix X670E-A and i miss the Async BLCK  Feature too.
