I'll give that a shot. However, I don't think installing GPU drivers after DDU will work. With the MODDED bios, I did an entirely fresh, clean install of Win10 and still was unable to install drivers w/o modifying them manually, so I don't think DDU will do anything in this case. Either way, I'm fine as long as it's normal.
Also, a manual OC only gives 70hz stable. Anything above that is fuzzy, so I'm not too sure why that's the case considering it was defaulted to 75Hz beforehand. I may try stock bios just to see what happens.
As asked before, what CPU can I install w/ modded bios?
