I have a Sapphire AGP X800XTPE here which artifacts straight from bootup. I was clocking it under DI a few days ago but I had a lot of trouble with voltage fluctuations, then finally sometimes it would artifact and then drop the screen or sometimes just plain go blank (in BIOS or Windows). I removed the vgpu mod, but I'm still having trouble. I think at least PART of the problem comes from this: when I check vgpu it reads 1.00v Is there anyway I can fix this? It *should* be around 1.4-1.45v I think for stock. I would be pleased as punch if someone could help me repair this, as RMA is out of the question and it doesn't look like the guy who sold it to me is happy with the situation (says it was working fine when he mailed it, and I believe him, just dunno wtf is wrong).

Thanks guys!
