hi i have a gtx 660 SC and i overclocked to get a stable clock of 1202 and i overclocked the mem to +275 and heaven crashes in about 5 mins but i can run BF3 forever and even most wanted so? should i just let the overclock be and ignore heaven? my power limit is set at 110%

how are the temps when running the benchmark? could just be the extraordinary strain is overheating the card.

try 120% power target, if that dont work, lower oc by 50mhz or mem by 75 whichever gives you stable oc

Programs like 3dmark or unigine stress the gpu. If running the benchmark using oced gpu lead to crash that's mean the oc was unstable. It might be able to run games just fine but after a long period the will crush if not the gpu will return to factory setting without while in game (in this case the game will not crash but simply unresponding for a few seconds). This means the gpu needs more power and to do so you need to overvolt the gpu.
