this seems a lil odd

hey guys, i have 2 x850 gfx cards in crossfire mode but i had a stab at oc'ing them. weirdly though when i set the clocks to 600/650 which is a fair increase, the cards seem to run rock solid but little mperformance gain. is it normal for cards, espically these to withstand such a high clock??

try 3d mark

already done o3, o5 and o6, like i said i didnt get much of a score increase, maybe a few hundred. 3dmark confirm the clock speeds. my main fear is if these cards can sustain this big clock

If you see little performance increase then there is no reason really to keep them at those clock speeds imo, but if they are stable and temps are low enough then equally there should be no harm done
