Driver, application and VRAM requirement?
Miep:
So, swapped in 6.08 and 2.2dll over night. [url-=http://setiathome.berkeley.edu/result.php?resultid=1661917453]task[/url] CPU fallback as before. Can't comment on the runtime, nothing available for comparison. Times for the 2 CPU tasks went through the roof. well actually I think they are about 2x the previous average, consistent with CPU fallback grabbing one core and the two CPU tasks having to share the other.
Right, now I get it. The incresed speed of V12 is not primarily due to the application, but to the fact, that the installer supplies 2.2 or 2.3 dlls... Nice work ;)

AFAIK stock plan class cuda23 supplies 2.3 DLLs as well.

Certainly does, but also checks for driver version (>= 190.38, IIRC) and VRAM (384MB) before it'll issue @ cuda23.
Frizz:
I recently got some WUs with Out Of Memory errors, like this one here:

I never had this before. Are the 512MB of my GT240 not enough any more?
Raistmer:
It's just "-12" error. It was discussed many times look SETI main forums for details.
"out of memory" is "out of host not GPU memory" and don't ask why C++ runtime library says that on exception handling ;D
