AMD - How To Overclock The Official Way Using Afterburner + Step By Step Overclocking Guide + Comple

If you want to play it safe try 1.100mv-1.150mv.

Thanks.

So far I've raised the core clock from default 900 to 1030Mhz and voltage from 1031 to 1063mV and I'm seeing a 5 fps increase in average and minimum fps on Unigine Valley Extreme preset, temps not exceeded 60c so I guess I'm on the right track. I hear 13.11v1 runs cooler too so might try those later.


One annoyance is if I get a freeze when testing, games run slower afterwards unless I reboot (even when clocks reset to default).

Yes restarting after a driver reset is part of the guide. I guess you didnt read that bit. :p

Also, the card is running at 70c while playing FC3 with only 1175mV core, isn't that a bit high? The card is only 2-3 months old so I don't think I'd benefit from re-seating the heatsink.

1.175V is still pretty high voltage for a 7950. As long as the card is below 75c when well clocked i wouldn't worry too much. Mine sometimes gets up to 80c when fully overclocked at 1.2v. You can always turn the fan up louder to cool it better or you can decrease voltage a bit. Your choice. :)

ok thanks. The fans are on 100% when at 70c but it doesn't bother me too much so I'll leave it, but I don't think I'm going to increase the voltage, I will see how high the card can clock with these volts.
 
I've maxed out the core clock in AB to 1100Mhz and seeing a whopping 5fps increase in Unigine Valley though seeing 10 frame increase in Metro LL benchmark.

Does memory clock add any real performance? Also any way to increase clocks beyond current afterburner limits? I cant really see any difference in my games that could use a boost. Fun experiment but gains not really worth it on my end lol

Yes, but core makes the most difference. You should still overclock the memory though. 1500-1575 is good for a 7950. 1600-1700 is good for a 7970.

You can tick 'extend official overclocking limits' with afterburner. This will remove those limits. Restart when prompted for changes to take effect.

I seem to have found my core limit. It's 1020mhz @ 1175mv, any higher than that and I get display driver crashes, pretty bad clocker this card isn't it?

I shall start slowly increasing the memory now.

Yep you have a bit of a stinker there mate. I thought mine were bad. :D

Haha, oh well :p

Also I was getting bothered by the fan speed constantly changing by a few %, the sound was very noticable. So I set the fan profile like this:

That way it's always on 10% when not gaming, which is pretty much silent. When playing non-demanding games it's at 30% which is quite quiet. Demanding games it goes up to 60%, which is a little loud but it's not too bad. The good thing is you never notice the fan change speed (or noise) which makes it better for gaming imo, it was annoying when even changing 1% (every few seconds) fan speed you could tell the difference in sound.

Lol i would be so mad hahahha. Im sorry about your 7970 :(.

Btw, i suggest you make it so the fan ramps up to 100% at 85c or so, i wouldnt feel comfortable running much over 80c.

It's a 7950, but thanks :)

And yeah might be an idea. At the moment Far Cry 3 doesn't go above 73c with those settings so I'm happy.
 
It's a good guide, so well done! I'm familiar with GPU overclocking, but for some reason I like following guides anyway, I guess it's the extra sense of security of following in someone elses footsteps.

Anyhow, I'm raising the core at the mo' on my 7970, currently at 1175 @ stock volts (1.11v). I've not tried overclocking this card yet, it's an RMA replacement. It seems to pretty good though.

ASIC around 80% or so?
