Thank You for information, Eric.

By the way, this card is not very bad, it is similar to GTX 960 from newer series. Maybe problem can be 2 GB of RAM, but according GPU-Z app using about 400 MB only.

Good luck :)

Hello,

I tried to run GPU application from here on my GTX 680.

According GPU-Z here is about 10-15 seconds of 90% GPU usage and then 0% for long time. For example I canceled this task after long runtime: https://numberfields.asu.edu/NumberFields/workunit.php?wuid=97780201.

Where can be the problem?
