most likely it's driver issues.
Try to use V12+185.85+CUDA RT2.2

BTW, do overflows disappear after restart (at least for awhile)? Do result's stderrs contain any CUDA-related errors?
I had overflows on x64 host with older driver+CUDA RT time to time before. Restarting usually helped.

XP x64
Driver = 185.85 = 6.14.11.8585
Cuda  = cudart.dll, cuff.dll 2.2 Version 6.14.11.2020  in Seti project
V12 FPLim8192
Did a restart.

There is no error except the -9 and not all of them are bad... I can recognize them now if the claimed points are above 40 they are all ok.
good http://setiathome.berkeley.edu/result.php?resultid=1296204656
bad http://setiathome.berkeley.edu/result.php?resultid=1296201169

On the other computer the problems seem to be less with 185.85 but they are still there.
They are even on the CPU but not as often.
My first guess is still.. that there are some really nasty WU out there. And that one computer could wind up with a lot of them.

Check "bad" link. It leads to non-overflowed and validated result.
[
it seems good and bad reversed ;)
Your "good" link contains overflow that didn't confirm by other CUDA host.
I start to think it's  PROBLEM with app, not driver.

Please, don't use this version on your host.
XP has no driver restart ability. If kernel launch longer than 3 secs it just will be aborted w/o user-noticeable messages.
If I remember right it will fail silently even not reporting error state (and this is CUDA flaw IMHO). So, try to use app with lower number in name.
IF it will run OK then we should mark "8192" as inappropriate for cards of your type (BTW, what GPU do you use? ).

BTW, it's _beta_ app so I'm not sure it's correct to discuss it in non-beta thread. You could report this issue in beta area.

He uses GTX 295, so that's the card it was intended for.  I'll Remove that build later, since it doesn't work.  Please refrain from posting about 'Beta' builds (from beta downloads) in the general forum.
