just purchased two 48701g installed ccc 8.9 and tried to adjust the core and memory sliders. if i adjust the core everythings ok, card runs fine. when i even bump the memory up 5 and test i get immediate artifacts screen actually goes green. ive removed and reinstalled ccc a few times same problems, ive tested both cards in cf and 1 at a time, same issues. not sure if its the cards or not. and yeah i could just not even try to oc the memory and bump the core but i dont like leaving questions unanswered. if anyone has had this issue or has some info it would be appreciated. thanks.
