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.

Have you got the latest beta bios for the B650E-E? Thanks.

Level 10

Why the different numbering scheme? On Asus site it says BIOS 1616 for X670E-I, but here 1515 is newer?

Level 10 is suppose to be the cream of the crop when its available.

Isn't that agesa already released? If you check official released bios 1616 on x670e-i it states exactly that agesa:

Actually, the new firmware in the news is

Ya I see that now. Either way can't overclock my ram without instability.

I'm super happy with 1515 on Strix Gaming F. The memory context restore option is working now. In previous versions as soon as you turned it on, bluescreens everywhere 😑

Without that option, memory training 6200MHz CL30 takes like 45s every boot. You press reboot, it takes a minute to see something on the screen. Now it's lightning fast. Like 2-3s.

Good job AMD on the new AGESA & Asus for providing this build. Hopefully memory context restore is stable for everyone and we can enable it by default.

Hi @Shamino 

The X670E Crosshair Hero 1515 test BIOS is not recognized as a UEFI file in EZ Flash when I try to load it.


Did you unzip if zipped and use bios renamer?

Yes and it renamed the .CAP file to CX670EH.CAP as expected. It just does not recognize the file as being a valid UEFI.
