Overclocking 6870

[Walter Sobchak]

What is everyone using to overclock and what are they getting?

Is MSI Afterburner 2.10 beta 5 the best utility to use?

Furmark for stability testing?

Ta.

Use Heaven 2.1 for stability testing, less intensive than Furmark but same results.

Thanks, any idea what kind of over clock I can hope for?

Agree. And download Lost Planet 2 benchmark and run Test A at max settings, resolution and AA. It will not make it through the test if the card is in anyway unstable.

Last two cards I overclocked, a GTS 250 and 6850, passed Heaven, Furmark, OCCT GPU and mem test, but failed Lost Planet 2 due to the memory being just that little bit too high.

Gaming is a better test of stability, Furmark/OCCT a better test for theoretical max temps but I see no point in running them for longer than a few minutes. Why put such a strain on your poor card and PSU for hours on end? Unless you need your room heating.
