OC'ing my 7950?

8ballslackz · Mar 28, 2013

Hey guys,

So I've decided to venture into the world of overclocking with a modest GPU overclock. Now, I'm about as new to OC as they come, so I'm gonna need some advisement here. As per this article, it looks like 1000 MHz for clock and 1575 MHz for memory are stable settings. Mind you, I don't plan to tweak voltage at all, and my CPU isn't OC'ed either.

To confirm, literally all I do is set up the Catalyst software in the manner outlined by that article and I'm good to go?

Theres no such thing. Stable varies from card to card, sable for you might be plus 10Mhz, but you could go out and buy the same card again and get 300Mhz over base clock before it starts crashing.

Don't use the AMD Overdrive software in the driver, its crap. Download MSI Afterburner and use that. All you are doing is bumping up the memory and core clocks until the card starts to produce a crash-to-desktop in a benchmark/stress test, I reccoment Unigine Heaven 3 or 4 for this.

Just keep going until you crash, then back off a bit. Don't worry too much about voltage yet, until you need more speed. If you have any worries just remember that you cant kill your card unless you give it more volts.

I disagree. There is nothing wrong with using the Catalyst driver for OCing an HD7950, and it saves you preloading yet another app for no reason (unless of course you want to go BEYOND 1100 MHz). Here's my settings:

1100/1500 MHz also gives a completely stable OC. In my experience, there is actually relatively little to be gained from massively OCing the memory - HD7950's seem to have boatloads of memory bandwidth. So if you're stable at 1100/1350 MHz (for example), then you won't really have significantly lower performance compared to 1100/1500 MHz.

I use the Evga whatever its called. It works good but I haven't overclocked to its fullest yet
