Crosshair VII Hero no longer allows Ram overclock.

Hey everyone,

I updated my mobo to BIOS 2501 the other day, and also upgraded my CPU to a Ryzen 3700x. However, I cannot set the D.O.C.P ram profile any longer. I'll get an un-documented "C5" error on the mobo if I try to and it'll stay stuck on post. Only way to fix the issue is by resetting the cmos and leaving everything to default. Anyone have this issue with recent upgrades? Or have a workaround?

Thanks,

Same thing here... set your ram manually... don't go to much cause bad boot will make you reset cmos to boot again...
And Safe Boot Button does not work with 3000 cpus Yet...

Try setting your vBoot to 1.4v.., had the same problem and that fixed it for me..

i think it is located under the memory timings option..
