I have experienced two failures on my AMD FX-8350 with two ASUS GTX 660 Ti GPUs. Can someone please help me determine the probable cause?

Thanks : errors shown below:

Overclocking too agressively

My system builder says my GPUs are not overclocked.....

Download GPUZ and see what the default clocks are and what current clocks are.

Yeah, I'd say your GPU clock is too high.

I'd like to know the exact make and model of your GPU, as well as GPU-Z's values for "GPU Clock" and "Default Clock" while a task is being crunched.

Hi, Jacob:

I am running under Linux Mint 17.2 and will have to look for a GPU-Z equivalent app.

Will be in touch later.

Thanks,

John
