Yeah, sure. As I only have experience overclocking a 9600, a X1950XTX and this 5870 baby feel free to edit it, correct it and adjust it for other cards. I don't expect it to be perfectly right with any other card, but I think it's indicating how not to reaching boiling temperature by accident while overclocking.
One eye on artifacts, the other on temperature, and a third on power.
That's actually something additionally that should be added. It's easy to make the card consume 50% more energy, and if the power supply is too weak it may go off. Also a card may already be designed so much near maximum cable-capacity that an overclock will maybe not grill your PSU but will make your cables melt away. In the past the cards weren't that power-hungry but today with a 5970 I expect it is a real possibility.

Saludos

Edit: Please don't take my statement about burning the processor literaly, of course we got a lot of security countermeasures in hardware nowadays which prevents the processor from simply bursting out in flames - but a little bit of healthy paranoia is necessary to keep enjoying your hardware for a long time. Try always to approach (any kind of) limit from below, not from above. With every new hardware new unexpected issues arise.

here's my ''custom curve'', ive found these settings work best with my ambients...... this curve keeps the fan speed @ 30-33% while idle & then has quite a steep increase once i start stressing the card


the steep increase actually results in a lower load temp with lower fan speed.....

what a great feature....

Feel free, don't hold that anger . I was scrolling and scrolling and it never ended . That was my point ... it was no axe or chainsaw or anything

luckily ''coffejunky'' edited it so i never had the misfortune of scrolling through the ''fan curve'' guide twice

Yes, that's exactly with what you should end up. Steep at the end to protect from the accelerated heat-production, combined with the effect of quickly cooling down the processor when the heat-bump goes away again. The exponential curve helps you to have a quick (and loud) fan for shorter periods of time.

I'm happy with you about your satisfying results!

Thanks for posting this guide. When ever i oced my GPU the 2d clock would never back down to a reasonable level. But now after using this guide i have my 5870 overclocked in games but when in 2d mode it is back to standard clocks and under volt ed. Thanks

Cheers to the poster

Question about GPUTool in Win7. Will installing the DX9 runtimes mess stuff up? It needs a dx9 DLL to run the artifact tester.

DirectX 9 should not be needed as a newer version is already installed. I don't think you can mess anything up by doing what it asks though
