Alpi Ohh, ok, not heard it. I use csm and legacy always but I can understand your pain.

Is is a known bug in the 7803 bios which apparently fails to initialise PCH as I read somewhere. UEFI Boot and as such Secure boot as well should not work anymore because of this bug.

You must enable CSM and boot into legacy mode = enabled in bios.

So you probably have CSM enabled.

Which ones?
The ones from ASUS or AMD?


I usually use AMD ones without problem. https://www.amd.com/en/support/chips...ocket-am4/x370


ASUS ones might or might not be the latest. But it seems they usually just repack them after AMD releases, hence the later date.

tcclaviger It's probably related to power limiting in the PBO settings and the scalar selected pushing the voltage higher causing you to hit the power limits at a lower clock speed.

It in no way negatively effects AVX performance.

EDIT: This is on my C7H, the C6E scores better in everything by about 2%.
Huh, guess it's cpu dependent then. On all the 3600's and 3800X I had it negatively affected the avx workloads

I have CH6 and 3700x . How I can do this EDC bug? I remember I tried and I got worse boost than my normal config!

MrXL Any news on when they will fix the errorcode '3d" bug in 7803 bios which prevents the bios from booting.

Ridiculous bug to rollout in official bios btw.

Sturmer Been long time since posting here.


Just curious
Been playing old games
Is there way to improve single core boost in bios settings or windows settings?


Any advices are appreciated


Thank you

Alpi Never seen the dropping Avx performance at me with Edc bug.
That unwanted downclocking happening at lighter loaded situtations. (or only 1 or 2 loaded cores) Global C state disabled helps most of the cases but not all !
Forcing the scalar turns it a lot worse at least high scalar wasn't any good for me with Edc.
Try diff. perf. enhancer setting (for example 2 or 3 if its at max., 4) just like try another energy scheme in W10 could solve.
(Normal windows balanced acted good multiple times for me)
Even starting hwinfo in the background solved this underclocking under Cb single runs just because altering a bit the way of load
