gtx580 bios mod?

[vern]

Hello everyone,

I have a weird problem with my POV GTX 580 Charged Edition.

My system:

i7 920 @ 4,4 Ghz
EVGA Classified E762

When I flash a modded bios to get max voltages I will get a black screen (no video signal) after the next restart of the pc. When I reflash the original bios, everything works fine again. I've heard of some other guys having the same problem with their GTX 580's. I was ready to return the card and pick up another one to check if the bios flash would work on another card and then I got the idea to flash the card in my old pc (Q6600 + Asus Maximus Formula with X38 Chipset). Now to the weird part, when I flashed the card in the old pc, I had a video signal after the next reboot. I thought great, maybe there is some sort of problem with X58 boards when flashing GTX 580's. So I put the card back in into my new machine and now I have a black screen again. I've been flashing my gfx cards for 7 years now, but I have never encountered such a weird problem.

Do you guys have any suggestions why the flashed card works in the old pc, but not in the new one? Btw, it's not a problem with my new machine, I had a bios modded GTX 480 working in it before I switched to the GTX 580.

I hope you guys can help me out, thanks a lot in advance, any help is appreciated.
