8800GTS 512 Overclock help

[colinstu]

I'm going to stick with the stock heatsink for now. The THERMALRIGHT HR-03 GT that [H] reviewed looked the best but I don't feel like spending more money and buying a fan.

In nTune I'm keeping my fan speed at 50%... anymore I can begin to hear the fan.

Right now I got the core at it's default 670MHz, and OC'd the memory to 1000MHz.

Pixel fillrate seems to be affected (if I remember correctly) if I increase the core, and texture fillrate & memory bandwidth increase from memory.

Any ease OC's this card should be able to handle?

What is a good way to test it's stability? Does that crappy looking GPU stability tester from ntune work?

I would scrap ntune and use Rivatuner - gives you better control over settings, including fan speed. You should be able to get at least 750 core, 1850 shader, and 1050 (2100) on the memory - maybe a lot higher than that. You can use AtiTool's stability tester to check the overclock, but it sometimes finds artifacts that you can't see in games, so I wouldn't use it as the end all be all of your testing.

I open rivatuner and it tells me that I have a driver that it doesn't support my driver or something (I got the latest one from nvidia's site...)

I can't find a way to overclock with it all, I'm guessing you press that small button after customize, mine doesn't have any OC stuff though.

You need to edit the configuration file for the current RivaTuner to recognize the 8800 GTS 512MB; see http://forums.guru3d.com/showthread.php?p=2576603

Here's the important bit:

edit RivaTuner.cfg

and change the line:

G92 = 610h-61Fh

to

G92 = 610h-61Fh, 600h

Awesome, thanks.
