Is this possible? Running stock voltages and stock CPU.

I doubt it. I've been overclocking NVIDIA mobile GPUs with Afterburner for a number of years and have never had any issues with any of them.

I think no it can't. You're safe as long as you don't overvolt the GPU.
Good luck.

You got afterburner to work on a mobile GPU? Damn it never worked on my 9800mGS. Only the one included in nvidia's tools did.

Either way the only thing I'd worry about is killing the fans sooner unless you alter voltages...then you need to worry about temps far more and over volting.

Yup, currently using it with my laptop's GT520M. Won't let me adjust voltages but I wouldn't even if I could tongue.gif Temps stay the same even when overclocked so, yay.

Okay, so i think it's safe to say that I could still OC my gpu when I get the whole thing back.

Since you're not raising voltages, the worst you could do is clock too high for the given voltage and cause the display driver to crash. Nothing to worry about as far as breaking anything though thumb.gif
