ATI Radeon 2900PRO/XT oc problem

[quake6]

:welcome:

Lets start. I flashed bios with 1.3v and went from 850 to 870(also tried flash it to xt,same prob.),everything above that is no go... I tried to flash it with riva tuner 2.08,ati tool,amd gpu... It is stable with that clocks in ati tool artifacts testing,but not in 3d mark,tried other things on default the same...

What could be a problem? If I make vgpu will it be like this?

And one more question,how much it takes voltage for let's say 950-1000 gpu?

Hey dude there is a video card section under General Hardware as well as a 2900 Pro Owners Thread (http://www.xtremesystems.org/forums/showthread.php?t=160458&highlight=2900+Pro+owners+thread). It's long but lots of info and knowledgeable folks who have also flashed their cards there.

Read all you can and post this there. Offhand I'd say temps are most likely your problem. If not the gpu or ram then maybe the voltage regulator. Or all of them.

I read it(not all :D),but nothing interesting about this... Temp. is about 70-75 at full load... I will make vgpu mod and flash it to old bios,but I think that there is some kind of other problem,but dont know what...

And sry for wrong section
