Hello there,
so i kinda got the same problem. So here is my story so people will be able to follow me and my thoughts.
I got last friday my Rog Strix 3090 OC been mega happy about it etc ... my mod kinda changed after i installed the new asus armoury crate/aura after that nothing worked anymore got problems with my whole RBG setup (motherboard rog strix z370-f gaming, rog strix flare and ofc the rog strix 3090 oc) so i had to roll back to the older version to be able to see at least any rbg lights on but i cant change the them on the motherboard anymore ... so i just gave up and wanted to chill and play some games
Today i decided to make the bios update which ended in a catastrophe while doing the update i got a bluescreen after that my motherboard decided to not find anymore my gpu ... so got already scared as **** ... after some time doing multiple DDU's in safemode and reinstalling the driver it finally worked again but ofcurse i got new problems which are that my gpu/memory clock keep going on max/min all the time but i didnt have this before so i asked for help in the asus rog discord and found a guy which told me to reset/reflash the bios again which i did but the problem stayed with the clock speeding up/down all the time. the guy from the discord told me to check for any app's that might be running in background 2D/3D and i found that the WALLPAPER ENGINE is cursing a error with GPU Tweak 2 ...
I changed now the multi display power saver as well and everything is back to normal which i'm not sure because as i said that i didnt have this problem before the failed BIOS update.
My question is now is it bad if the clocks are going up/down all the time in idle on the destkop (leaving multi display power saver off)
I guess i will leave it on anyways now but find it kinda ****ty from ASUS that they are giving out hardware so expensive and many things are just not working as they should
Thanks for reading
