Solved nVidia Graphics Driver crashes on GPU overclock

Hi.

I have a brand new ASUS GeForce GTX780 OCII (+something something). On the driver CD, there are overclocking software and nVidia GPU driver software. I use the OC software to boost the GPU clock (and such). The problem is:

Once I start a game (or gives the GPU something to "work with") after overclocking, the nVidia graphics driver crashes and all my screens go black. I end up forcing a shutdown on my PC most of the time (however, on rare occasions, Windows manages to re-start the driver).

(I don't remember the driver version, but it should be the newest one) I have tried re-installing all software and drivers for the card with no results. Does anyone have a solution for this?

If infinity is infinite, is the square root of infinity infinite as well?

Don't overclock it then.

Ditto phil22. If it's unstable after you OC, then don't OC. End of subject.

Although if you STILL want to OC, then just take whatever settings you were at and back them down the scale until it becomes stable. The only real way to test an OC and see if it's 101% stable is with a program like Furmark, running for at least an hour. Also be aware that with overclocking, the GPU will be getting hotter than at stock speeds.

✔ Best Answer
Note that the driver on the CD are not usually the latest, download them directly from NVidia.
Yes, back down on the OC and monitor temps while testing for stability and while gaming for at least a week after you manage stability. If it is running hot while gaming you will need to back down on the OC, increase the fan speed curve, and/or improve case cooling with a better case fan(s) or possibly an additional fan depending on the case configuration.

You have to be a little bit crazy to keep you from going insane.

Well, I suppose I'm just gonna leave the overclocking be... The GPU is good enough as it is. Thanks everyone :)

"I have a brand new ASUS GeForce GTX780 OCII (+something something)"

You can't even provide the proper info on a brand new card? I'm sure it's printed right on the box! My guess is it's the GTX780-DC2OC-3GD5. The OC in the model number means it's already factory overclocked. Are you experienced at overclocking graphics cards? You should increase the GPU & memory clocks a little at a time, then test for stability after each change. My guess is you jumped the numbers up too much all at once.

And you should be using the following driver:
