I did a bit of overclocking last night (485/1360) and noticed the card throttling, so 480/1360 is the best I've got. It was 1.5v gpu and watercooled with a Maze4. I shutdown last night and this morning, it boots, does the Windows XP bar then freezes at a black screen, sometimes, blue bars going vertical on the sides. I wiped the driver, cleaned the registry and reloaded 66.93. No luck.

It will boot into safe mode and run the stock VGA driver fine, but the nVidia drivers, (61.XX included), cause the black screen freeze. I've tried 1.5 & 1.6 AGP voltages. Nothing else has changed in my config since the last time it ran fine.

I think I've fried the card. I did a search and couldn't find anyone with a similar problem. Anyways, :cry:

Did you try flashing it back to it's stock BIOS?

Yeah, I've flashed back to the stock bios and a couple of others with no results.

Yea, I'd say you might have killed it.

The only other thing I might suggest, is a new windows install, since it only messes up in windows.

Other than that, I'd say it sounds like you fried your cards memory/something connected to it. Sorry.

Try downloading and running a linux distro that runs off a CD. If it messes up while running that, the card is toast.

I might try that this weekend. I just modded a bios for 1.3 vgpu and 350/500. It booted fine. Looks like I can say bye bye to 1.4 at 450/1200. Thanks for all the advice. I just took an Ultra and turned it into a NU, :bang head

Looks like a messed up the voltage regulator. I have to undervolt the bios but I'm back at 450/1200. Did a few loops of 3dMark03 with results matching prior runs. Shame on me for trying to volt mod. Lets see if Half Life 2 survives the night.

Take the sink off your fets and mod it like I have modded mine. Its possible that they are overheating. Link to mod:
