Modified SETI MB CUDA + opt AP package for full GPU utilization
Richard Haselgrove:
Note that there was a server-side modification on the SETI Main project (and presumably Beta too, though I haven't seen any direct reports) about 21:30 UTC, Monday 22 December.
The minimum GPU memory requirement was reduced from 256MB to 254MB. Many of the smaller cards were reporting 255MB, so were switched from 'just too small' to 'just big enough'. That may well account for some users getting CUDA work, when it was 'not available for your [type of] computer' before.

Sure, very possible.

Extended outage? Could be promising, ... or not :-\
Jason G:
Okay, Pre-Release Boinc 6.5.0 *seems* to have fixed the +1 operation such that you don't need to set ncpus in cc_config anymore. Well that's a start.
[..And base priority seems to be 'below normal' now too, might have fixed some of the pauses I was getting. We'll see... That's two annoyances down! ]
[Edit: Make that three! ... It seems that it's no longer suffering from oversubscription here either. Will observe during new cuda task changeover to confirm.]
Raistmer:
I tried 6.5 on x64. When boinc manager closes it closes only its windows. Process remains in memory and consumes full core (50% on duo).
I tried few times, after reboot after aborting process and so on - it always begins to consume CPU.
So I reverted to 6.4.5 that is official release now (at least for x64). It's pn Win2003 x64 host where I tried to run 2 CUDA- enabled GPUs simultaneously. 8500 ang 9400GT.
it seems only with 180.84 beta it will work w/o out of memory after each tak restart...
