There was a bug in the older BIOS that caused the cards to throttle when OC. Link. Though I honestly couldn't figure out what this guy was asking for. Fantastic program BTW. Using it with Borderlands 2 with dual 7870XTs it's smooth as silk, reminds me of old CRT days. Can't use RP's triple buffering though, have to use DFC with Vsync Control on. DVC causes a lot of stuttering. Is there a list anywhere of AO profiles? Also, it has an issue with MS Office 2013.
