I don't have any experience with C, or any low level hardware programming. I am able to restart ethminer over and over at these high mem transfer rates and it fails in a short period each time. It was reported on both GPUs simultaneously as usual, despite only changing the rate on one of them. Increased mem to +1900 on only one card and the error occurred again. It ran for about 30 minutes with no problems. I dropped the mem to +1500 and started again.

It ran stable for about 2 minutes and errored in this way. Changed to +165 core and +2000 mem using the nvidia x server settings gui. I ran it for about 90 minutes at stock GPU settings with no error. It may be related to overclocking, contrary to my prior observation in #80.
