X1800XT 256 What's Your Overclock???????

[Cobalt]

I got 640/770 on mine with the stock cooler. I upped the fan speed a few percent and now it idles at 47 (was 50 before fan speed increase) and loads at a max of 71 but for the most part it stays around 67. HDR + AA is what causes it to jump to 70/71.

I plan to re-seat the HSF with some AS5 to get some better temps but I need some thermal pads to use for the RAM. I may have to use the Akasa CPU pads and cut them down to size or get some Artic Ceramique but both seem too much trouble.

I got 720/800 with zalman vf-900 using ATitool, running daily at max CCC though

Nice, game stable? extra volts? temps?

I could do 3dmark 05 runs at 768/868, on the stock heatsink, with my PC on my window on a cold winters night.

My 24/7 clocks are 690/800 in CCC, no extra volts, idle temps about 45C, load about 65C, but it will get hotter as summer arrives.

At the moment its 650/780 which is stable while playing Oblivion. The core freaks out at about 675 when playing oblivion. Just using CCC to set the clock speeds.

it was for benching, irrc 1.4v core, 1.9x vram, temp around 42 idle, 65-67 underload with vf900. for 24/7 I use max CCC with default voltage

New clocks for me: 660/792. Reseating the HS and a little creative fan speed monitoring gave me 60*C average load with 64*C with HDR+AA. Thats with increased volts as wel . I recon I could do more but its ample for now and it gave me 700 3DMark points + smoother gameplay in Oblivion.
