4870 Overclocking Thread

[demowhc]

, I think I just bricked my card... I tried to change the VOLTS... and the biosflash said it was succesful.. but now it doesnt put out video....

Is there a way to undo a bios change, and even reflash? monitor just goes into standby now. PLEASE HELP!

Or do I have anyhope with a RMA? or anything?

I have a 8800gt, so could I have both in the computer and just flash the ATI? is so what should I do? Thanks for anything.

9999.9GB/s bandwidth.. nice

yeh I'm a bit unsure about voltage aswell.. I'v heard you can only go up to 1.3??

Yeah, there is some mad artifacting with 4870 and OC. My XOC artifacts right out of the box. ATITool will show it to you easy. I finally managed to get a stable 850/1150 thought, artifact free and very solid. Max GPU temps are around 65C. The volts are 1.349 core and 1.598 memory.

Btw, if you want the XOC BIOS I posted it here...
