Video Flickering after undervolting, GTX 480

post #1 of 3
Thread Starter 
Hello, I started to undervolt my GTX 480 because it brought down temps tremendously. I brought it down to 925 Mv (default is 1075) and I started a game, the driver crashed, recovered, and set everything back to default.

After that crash, every time the card ramps up from a down clock, the screen flickers once and it lasts about half a second. I don't mind the card down clocking when idle or whatever and always has down clocked while idle, but the flickering is starting to get to me. Does anyone have any solutions to this problem or did I break my GTX 480?

I've tried unplugging the DVI cable and reverted to old drivers seeing the same problems (Currently running 320.49)

This happened when I'd go from stock clocks to overclocked settings with MSI afterburner, when I had my 480.

Never seen this issue, but am not saying it does not exist.

What core and memory clocks are loaded when you undervolt?

The 480 i have left over does 710core and 2000 memory at 0.925mv without instability or the problem you have mentioned.


Also what model is it? is it also an early model?
