Hello everyone , i bought my xfx hd 6850 dual dissipation and i made a little overclock in it without change any voltages , my overclock is good or are too high ? ( the max temp is 65° and the stock was 61° full load )



comparison between after and before the overclock ( 3dmark 11 )



i tried push the gpu clock to 940 but was unstable and needed turn back to 925

I've OC'd a single 6850 to a stable 900/1200 on stock voltage. Only time it would crash is if I tried to play ARMA 2 while over clocked. My temps were hitting 70-75*c when under super heavy load

I've got my xfire 6850s OC'd to 900/1150 stable but I havn't really been pushing that OC because I don't need to. Temps hit 75 when really grinding along but usually its 65-70*C range.

I reduce the clock to 920 and 1120 memory clock , i saw some weird lines on the screen , i guess the can't be stable above 920mhz and 1150mhz without change the voltages , i really didn't see any artifacts just this weird lines when my pc was turned on

My highest stable clock was 950 / 1100

Didn't notice an improvement over the 900/1150or1200 clock speed.

i tried 940 / 1150 the improvement was minimum but if you test for many hours you will see the its not stable
