Overclocking the 6800GT...

TB303 · 11-25-07, 04:07 PM

Hi People,
I have a good old trusty XFX 6800GT that now barely "pulls" in modern games. So the time is now to OC it and hope for the best.
I replaced the old and faulty fan with an Accelero X1 - and now the card idles at 55c and reaches 65C at load while running (425/1050)!

Anythign higher than 425 - Core and I start seeing artefacts. However the low temps, suggest there could still be room for improvement. I'm wondering if the card is running out of juice and if I shoudl bump the voltage, it's currently 1.60 I can do 1.65 in my Mobo's (AV8-3rd eye) bios.

Another thing which may be affecting stability is the fact I OCed my CPU - an A64 +3000 @ 2475 - it results in the AGP bus running at 68Mhz, and I could potentially get it to 70Mhz

Please share your thoughts,

PS
Sorry for the double post...

Many thanks,

already at 1.6V and you want to go higher? (default is 1.5V) Your going to cook that thing too bits reguardless of temps. Your probably at the very max it can pull. If your willing to push it even further, be willing to buy a new card just incase.
