Driver, application and VRAM requirement?

Miep:
So, that did the trick.
memory usage up to 218, no errors.

Fine, stock 6.08 working on 2.1 dlls - does the optimized V12nokill whetever require 2.2 dlls or will it run on the 2.1?

Raistmer:
should run with 2.1 too as I can remember. Good that you able to use your gpu now for seti

ThE`e's not much in the way of actual optimisation in V12, kill or no kill. A bit of startup delay eliminated, and a higher base driver requirement (but you're well past that limit already). The other change was the priority mods, but they got incorporated into the later BOINCs.

The best step you could take, speed-wise, would be to step up the DLLs. Now you've got it working, would it be worth trying once more with 2.2? Suspend all CUDA tasks after the one that's currently running, drop the new DLLs into the project folder, then release one as a trial. Don't even need to stop BOINC for that test. If ht works, bigger gain than any of those early experimental builds.

Miep:
Well I upgraded BOINC to 6.10.58 and swapped the V12 back into app_info.  seemed to run, but as usual will have to wait over night.
I dn't think 2.2s will work Richard, the CPU fallback stopped as soon as I had dropped the 2.1s in...
I can try tomorrow, but I had initially V12 running on 2.2 and that just errors out - on 6.08 it drops to CPU. With 2.1 I get load onto the GPU...

Richard Haselgrove:
I'm really surprised at that - the 2.2 DLLs caused no problems at all when they came out, and the FFT DLL itself is only 1MB bigger than its predecessor (have to ask Jason what the actual difference in FFT processing is, and whether it needs significantly more space for data handling). Trouble is, nobody else has really stressed out 256 MB under Vista before (though IIRC, Claggy eventually got 128 MB running, also on a mobile GPU - or was that just testing the CPU fallback code?)
