Same here, suspending them at any point crashes them.

4.0 and 4.2 seem about the the same on my 680, settings are:

K1024 I524288 S0

Getting 99% utilization on GPU

S0 vs. S1 seems to have no effect.

Stock 2.3 was about 1550 sec.
4.2 is about 1200 sec.
The 3.11 Open CL version was slower than either for some reason.

Is this project DP or SP ?

Changing the K value to 256 is giving me about a 92% utilization on my 680 now. You can change the S1 to SO but it will use a whole core.
Question, when I change the app info file, do I have to exit Boinc and reopen to read the new values, or is there a better way?

1500 sec. with 4.2 vs. 1843 sec. on stock 2.3 app.

instant errors here also on my 680. I will be cool if it gives as much improvment as it did at GPU Grid, 30-60 percent faster there.
