OCing an unlocked HD 6950

[Rhezuss]

Ok, last week I received my Sapphire HD 6950 2gb model 11188-05-20G. Not the Dirt 3 edition but the same dual fan model. I was lucky to have a card that unlocked simply with the switch. So after moving the switch and rebooting, I had 1536 shaders at the HD 6950 clocks of 800/1250.

So I used MSI Afterburner to up the clocks to HD 6970 value of 880/1375. Tested it in Kombustor (but that is irrelevant because the GPU usage showed like 25 to 70%...I don't know why) and then I ran Heaven DX11 Benchmark. No artifacts in those. Then I fired up some games like Crysis 2, The Witcher 2, AoC, Starcraft 2, etc. No artifacts either.

Now, knowing that the card was pushed from 800/1250 to 880/1375...do you think I still have room left without playing with the voltage? I just don't want to brick my new card 😛

What are you trying to accomplish? Do you need more performance or are you looking for bragging rights?

From what I have seen in reviews (and running my 6950 shader unlocked) there is very little to gain from pushing a 6950 past 6970 specs.

Ah ok, didn't knew that and I sincerely couldn't care less about bragging but thanks for asking 😛

I'll leave it at that since it looks like it's stable and enjoy the free power.
