Overclocking 7900GT, need more

[Trendy]

I can't really get all that much out of my XFX 7900GT.

The stock speeds are 470mhz/1.37ghz. The memory does okay, getting to 1.6ghz before RivaTuner tells me it's unstable. The core clock speed, however, only gets to around 520mhz before it's unstable.

How can I push even more performance out of this card? Do I need new drivers? (I'm using the latest official Nvidia drivers)

it needs volt mods to get higher, go to google and look for 7900GT volt mod.

I was able to attain an extra 20mhz stable by going from 1.4-1.5v on my 7800GT, doesn't sound like much but it can help with the minimum frame rate dips.

Thanks. I'm more or less OCing it for benchmarks though, I was hoping I could get more performance with minimal effort lol.

The most intensive game I play atm is BF2142, and I get 70ish FPS with all max settings (cept AA = 2x, not 4x)
