GPU returnsfailed

The links to the two task show that they ended up as "Validate Error".
This usually means that the tasks finished without any apparent error but the result that was uploaded to the server contained something that should not have been there.

The usual suspects are:

• * Heat, check for dust build up, clean if necessary
  * Overclock, go back to stock if overclocked, maybe even downclock if not
  * Power, check if the power supply is good and up for the task
  * Drivers, if recently updated go back to previously working version
