So, I am performing the basic, simple overclock that every reviewer, at least, is saying the card can handle at stock voltage without a problem: 1125/1575 (cannot find a way to OC beyond that anyway). I know every card is different, but these reviewers also say the HD 7970 can overclock well beyond this without even having to adjust the voltage. Anyways, after the OC, I run FurMark fine with no artifacting for 15 mins. I run 3DMark 11 with no apparent problems, and Heaven with no apparent issues. However, after I load up a game (Portal 2, Witcher 2, Skyrim, BF3) they all eventually start doing a strange texture flicker on some elements of the environment. It doesn't happen immediately, usually after the game's run for a minute or two. The flicker is white usually, like the textures are disappearing and reappearing. Sometimes, I see a checkered pattern in the flicker. This does not occur when I remove the overclock. The max temp I usually get while playing with the OC is around 78 degrees. I have used MSI Afterburner to try changing the voltage higher, but the flickering still happens. Anybody else experiencing this issue while overclocking? Should I be worried or is there a chance this is just an issue with AMD's drivers? I really want to OC this card. Is there a chance I received a bad card that just doesn't like to be OC'd? If anybody has some insight to this problem, that would be awesome. Thank you.
