Need help with overclocking msi 7950 oc tf3

I recently purchased an msi 7950 oc tf3, running with an i5 3570k at 3.4 ghz and a 650w corsair psu, on a pro3 asrock z77 motherboard. This is the first computer I have ever built and I was wondering if I could further overclock the already factory overclocked card. It runs at 40 deg idle, and up to 80 deg running bf3 on ultra on a 1920x1080 screen. is this way too high or do I still have space to overclock? Please also if someone could tell me what to overclock using MSI afterburner. I do not know much about OCing. My core clock is at 880 mhz and my memory clock is at 1250mhz.

80 degrees celcius is a bit acceptable but could be harmful to your VGA in long playing hours. 70 degrees is the recommended max temp of VGA in long gaming hours. If you could find a way in lowering your temps you could still overclock as long as your system is stable :)  Hope this helps :)

you sure that's not a 6950 ?
cause those readings are awfully similar to my Sapphire 6950....... :lol: 

Keep it under 80, IMO.
Though the MSI 7950 should have a rather good cooling system and unless you live in the tropics, you shouldnt be hitting that high .
just my 2 cents

Go to afterburner and set the fan speed to max.You'll definitely find 10-15 degree temp reduction at load.
Then you can try raising the clock speed to 950mhz or at least above 925mhz(which is the clock speed of 7950 bios boost editions).

Since you're using AMD, get the Sapphire's TrixX.
IMO, it's better than afterburner in OC'ing and fan control in the sense that you don't have to reboot to set OC clocks and it also allows higher headrooms.


set it to 1 to 1, on the fan speed percentage against temperature graph

since when did you have to reboot to set OC clocks when using afterburner? :o

Since last month when I first tried out afterburner, could just be me though :/

Thanks very much for all the help. Is there any advice you could offer me? I have just re-done all the cabling in my pc to max airflow and I'm still around the same temps. idle of 40deg, peaks of 83deg celcius in bf3 on ultra and some high. I'm getting a constant fps of 70-73 though. Is my card the problem? It's still under a 30-day 1 for 1 exchange. Should I bring it back then?

Nothing's wrong with it, I'm betting it's just the fan profile

haha..indeed. I live in Singapore and right now it's about 27 deg cel. It can shoot up to 33 deg here though. could that be the reason why?
