I got through the first set of wus on all my nvidia cards.

The 570's completed 1 wu in 41,000 sec and haven't validated yet

The 560ti completed one wu in 42,000 sec for 24,988 credits - the Stderr output is below:

=====================

All of the genefers I have run have failed at least once with my wingmen, some two and three times. In looking at the Stderr outputs for their work units, most seem to be caused by overclocking. Don't overclock and you should be fine. The temps I was concerned about have been a non issue this time around for me. None of my gpus are running over 70c with 70% fan.
