7950... Hmmm

post #1 of 3
Thread Starter 
Well just installed it not to long ago. I'm pretty pleased with the card as it's the first time I can actually play games on ultra and all but It does have some "issues" not sure if anyone else gets them as well.

I went with the sapphire dualx 7950

I get pretty bad coil whine not sure if there is a way around that

1150/1550 overclock... can't go past that? voltage is at 1.25? Can't bump it up either using trixx and all that (i've seen people with higher clock smh)

SOME games stutter on intense scenes. Thought it should be buttery smooth compared to my old gtx 460.... confused.gif like mirrors edge when there's a massive shooting (yes old but I love that game!)

anyone else have "issues" as well?

Have you maxed out power control to +20%. First test your overclock for stability. It might be better to start at 1 Ghz core and stock 1250 Mhz memory. Test Heaven 3.0, 3D Mark 11, BF3, Crysis 2. Also with GDDR5 memory errors can reduce performance when you push the clocks too high. Push GPU clocks in 50 Mhz steps. Make sure your GPU performance is increasing at each step in Heaven, 3D Mark 11. the min fps can give a good indication if your memory overclock is reducing performance. Aim for 1.1 Ghz and 1400 Mhz with complete stability. Coil whine can at times be reduced by running games with vysnc and capping fps to 60.
