1) Message boards : Number crunching : Most of my WUs are getting Computation Error (Message 51228) Posted 26 Sep 2011 by Mitch Post: Still getting errors on milky way only. Win 7 Pro, Boinc ver 12.33,Nvidia 266.58. It must me something on this machine. Other machines are fine and I changed video cards from a GTX 285 to a GTX 275 and I am still getting a lot of errors on milky way.

2) Message boards : Number crunching : Most of my WUs are getting Computation Error (Message 51224) Posted 26 Sep 2011 by Mitch Post: I shifted to Collatz and 100% are error free under 266.58, but few are successful under milky way.
3) Message boards : Number crunching : Most of my WUs are getting Computation Error (Message 51220) Posted 24 Sep 2011 by Mitch Post: Try 266.58 instead, CUDA 4.0 is the most likely culprit. Tried 266.58 and still getting errors, I really want to donate to this project, but only half my WUs seem to be successful.

4) Message boards : Number crunching : Most of my WUs are getting Computation Error (Message 51202) Posted 24 Sep 2011 by Mitch Post: The latest Nvidia drivers (280.26) seem to have some OpenCL issues. Try 275.33. Not sure if it's the driver's fault or mine yet. Although going to 275.33 has helped, I now get more successful completions, I am still getting 50% error rate.
