I havea HD 7850 and it is overclocked to 1200mhz core and 5400mhz memory on 1190mv'si have seen a really good increase in performance on the card. I havent had a crash yet at 1200mhz, and if you do see crashing, just bump up the vltage a bit on your card, what cooler is your card fitted with? I personally fitted the arctic accelero twin turbo II on mine and its amazing, i max out at 52oC and my ambient is at 28oC usually. And it isnt even audible over my hyper 212
Im not exactly sure what cooler it has as I have not purchased an after market cooler yet so it has the stock one. I hear the 7870 runs pretty cool with stock though. Thanks this information does help give me an idea of what to expect as im pretty much a noob lol
I just picked up a second hand Sapphire HD 7870 and it seems to be overclocking a treat. Got it to 1240Mhz and 1450 memory and then took the voltage DOWN to 1.170 to try and keep temps down. Got a max temp of 80.
İ got the Sapphire one with dualx cooler İts meh you got it with stock voltages it got up to 1180mhz on core and with 1.280 (1.250 stock) it got up to 1200mhz my max temp is 80 by the way my mem is 1340 i got 5-12 fps more
