My water cooled GTX 280 story.

[003]

Ok it looks like my eVGA GTX280 SSC is quite good under water. After some preliminary testing, it seems that 783/1674/2484 is the best absolutely 100% stable OC I can achieve, and with only 1.1625 vcore! Stock vcore is 1.1875. This is stable for 4200+ seconds on FurMark 1.6.5 @ 1024x768 with Xtreme Burn mode enabled, 0xMSAA and no post processing. Lack of voltage is holding me back from increasing the shader and core clocks, and VRM temps are holding me back from increasing voltage. If I had a FC block & dedicated loop, I think I would be looking at an 800/1700+ 24/7 FurMark stable card here! Here's the screenshot:


I can run the core at 792MHz relativly stable, but it would occasionally cause an artifact in FurMark. Only very seldomly, though. I am very anal and like my stuff to be 100% stable. If I could run STOCK vcore here, I have no doubt 792MHz and up would be stable with relative ease. Again, VRM temps are the limiting factor here. Take a look at the screenshot

Edit:
Note that I have not tested any higher memory speed. I just set it at stock 285 speed and left it alone. It may be stable at higher clocks, I might get around to testing that at some point.
