I consider CUDA MB preempting as bug even it will not be leaved in memory.
CUDA initialization is costly, CUDA task should never be preempted w/o real and urgent reason. They don't take too long to preempt them anyway.

Is there another BOINC version that doesn't switch between CDA WU or is there any way to prevent it..
I now feed about 100 CUDA WU  a time and the rest is suspended (works great but I'm baby sitting). If I feed more BOINC and my computer crashes :-[ as BOINC starts switching between WU.

Unfortunately, no AFAIK.
My BOINC-disobey build will not help here, cause you have many CUDA MB preempted - if they all will continue to run you got CPU fallback very soon...
