8800GTS G92 water cooling -- any point/suggestions?

[sinephase]

Using EVGA precision and upping my fan to 85% with 800Mhz GPU core, 2Ghz shader, and 2.1Ghz mem I didn't go over 65C (at 100% fan I didn't go over 59C), and it was only moderately stable, so I infer it's not a cooling issue.

I have a corsair TX650w PSU rated for 52A on the 12v rail, so I don't think it's a PSU problem either. My setup runs stable at stock settings.

So I guess I have 2 questions: what do I need to do to get this OC stable, and if it's really not possible, is there any reason to get water cooling because I'd only need it for an even higher OC?

Also, does anyone think it could be a voltage issue at that point of OCing and what I could do to increase the GPU and mem voltages on this card?

It's not cooling or power, just the gpu itself. All g92 8800gts oc reliably to 750mhz. Some goes up to 800mhz, but you have to be lucky. 800mhz didn't work for me either. It's stable in game, but crush on stress test (Fur Rendering). Highest stress stable I got was 790mhz. It's not that much difference anyway, just tune it back a little.

how about lowering the vram speed and up the core higher. because een though the core is not going above 65C but the memory chip is more vulnerable to heat.

i didnt get my GTS 512 stable at 800mhz as well.only stable at 783/1890/2000. tough luck!

I ditched my gfx water cooling for a Thermalright heat sink.
Means i can run the cpu cooler with a smaller rad, and with a good 92mm fan it runs hell quiet and cool.

No point IMHO.
