Trouble OCing my graphics card EVGA GTX 670

I got a nice OC out of my cpu. I can get a good OC on the GPU OC over 1ghz... however... When trying to play bf4 with my GPU OC at 1ghz the game crashes a lot. Also, if i speed up the memory even 50 mhz it becomes unstable... Do i just have a trash video card? or am i missing something here? I have seen people clocking their memory up to 6000 mhz and 1ghz GPU with this card. The temps are fine on the GPU...

no. unlike cpu's graphics just doesnt always work overclocked. it can happen. and i think the evga is already factory oc.

I know the clock has variables such as if the GPU can handle it, the specific build of the system, temps, etc... but most people successfully overclock this card without any problems. I try to run heaven with it and it locks up every time if i go over +50 on the memory and i think i got the gpu clock to 1080 ghz. if i go over +50 mem it crashes heaven. the 1080 GPU clock is not very stable in heaven but did provide the best score so far. ive kind of given up on ocing the video card. i really wanted to oc the memory because i heard that really speeds the card up... so im pretty dissapointed.
