GTX280 Overclocking

[[TW]Fox]

With the release of the GTX285 and the obvious considerable damage to my ego as a result I set about making my own GTX285 by....

...clocking my 280 to 285 speeds. Seems to work perfectly, no artifacts, no crashing and when playing GTA or Race Driver GRID it never seems to go much about 70-75. I've used Rivatuner to setup fan profiles as well.

So, largely happy with that. GTX285 performance without the GTX285 price tag.

But how much higher can I go? What should I expect from a bog standard (non factory OC) XFX GTX280?

Erm I think there where some weird benchmarks around whereby a GTX280 @ GTX285 speeds was still slower than a GTX285

Really? I thought the only practical difference was clock speed (And the smaller process, but this merely aids the acheivement of higer clock speeds and doesnt increase clock for clock performance?).

Your card should easily match BFG GeForce GTX 285 OCX or surpass default clocks of that card, to some degree, certainly the core will.

- Core Clock: 702MHz
- Memory: 1024MB GDDR3
- Shader Clock: 1584MHz -
- Memory Clock: 2664MHz (Effective) - not to sure on the memory clocking that high on the 280.

A bog standard 280GTX should easily do, 702 - 2400 - 1500

That's what I thought, I think they were posted on OCUK, I'll have a look.
