Hey guys , i've bought a sapphire hd7770 OC ghz edition , and it came with stock clocks at 1100 core and 1250 memory , but the drivers keept crashing when i was playing any game...so i found that the problem was the core clock, which i reduced to 1075 and it was stable.. then i start uping the memory clock and the voltage and now i have 1075 core and 1500 memory clock and the card is stable , the memory bandwidth has increased from 80gb/s to 96gb/s which i think is good for an overclocking , i'm just wondering how much more i can push the card.. and maybe fix the 1100 core clock crashing problems :)

yea i've checked and a lot of guys have the same problem as me ( gpu crashes at stock clocks) , but with only a 25mhz reduction in the core clock the card becomes stable and overclockable.. i'm planning to buy a new pc btw with a gtx770 or 760 , but i really wanna push the hd7770 to it;s limits before i buy a new one
