Watercooled 8800gtx

My first watercooled GPU.

I'm using an XXX XFX 8800gtx, which at stock was ranging temps from 63C-80C (idle/load), speed 630/1000.

I'm a little unsure how to really put some juice into it, now that I have it on watercooling.

I'm at 650/1000, 41C idling, but when I run 3dmark it only goes to 44C? I want to ASSUME I can just overclock with Rivatuner, and that's it right? when should I stop, when 3dmark crashes? Do I need to add voltage to my southbridge? What about the PCIE speed, leave it at 100MHZ?

I think everyones idea of oc'ing a gpu is different but I just use coolbits and do mine that way...

I guess what I mean is, I don't need to change the PCIE speed or add voltage or anything?

I set mine to 100 and have never volt modded a gpu so I couldn't help you there bud...
