So just an update with things and my overclock. I am so far stable at 4.6ghz with these settings. I ran aida64 for 24hours and it came up with no errors, temps hit max 76 over that time. There is 1 thing though that's odd, 8pack told me to set uncore but the system won't boot if I touch that at all ? I have to leave it on auto. Is that a problem? I did read online some people having a problem with the gigabyte boards when messing with that setting, but I am on the latest bios which didn't seem to help.
XMP set
100 X 46
CPU Vcore 1.28v
SA 0.5v
CPU Vrin 1.9v
CPU ring 1.10v
I am not sure if I should try for 4.7ghz tonight, but would defo like to know why I can't touch uncore. Core voltage seems good though and at 4.5ghz only needed 1.25v
