overclocking 990fxa-ud3 r5 rev 1
I've seen videos showing someone using this card and they were able to do it too.
I've seen videos showing someone using this mobo and they were able to do it. That's what I'm trying to say. Either you're missing something or the board might have an issue. I used to own a couple 990FXA-UD3s, a rev1 and a rev4, but not the newer R5. Maybe I'm forgetting something because it's been a while. But look through the BIOS for any auto settings that keep the multi from being set, and change it to manual. You might also want to check for a later BIOS version. It's not that the old one won't work, but updating it sometimes fixes problems.
