Powercolor 7950 3gb Boost overclocking

[XiandreX]

Hi all

So I have this 7950 3gb boost

http://www.wootware.co.za/powercolo...dragon-tomb-raider-and-bioshock-infinite.html

Right now I am running 1150 core 1275 Memory. I am trying to work out if more memory and less OC on core is better but not sure. I am running stock volts obviously as I am sure it's voltage locked. My 3570k is @ 4.4ghz if that helps.
What should I change if anything for an ideal overclock of core/memory?
I am running the Xfx 550w pro series ps.
Trying to find a balance is all.

Thanks for any suggestions you might have.

Many thanks

My understanding is that you want to maximize core more, as the card has plenty of memory bandwidth already.

For reference, my card runs at 1125/1425; doesn't seem to want to do more core MHz at 1.25V. Memory could probably go higher, but there is really a point once you get up there AFAIK.

Powercolors are rarely locked, you may just need to enable 'Force constant voltage' with a beta version of MSI Afterburner.

Clocking up the memory doesn't give you very much, the GPU gives you the most. The 79x0 series cards have tons of memory bandwidth, so its not really a bottleneck.

What is a safe range for increasing the voltage?
