I found the answer to my question about such compute errors.


Lesson carefully owners of double gpu video cards.

The problem seems to be drivers related. GPU compute apps and boinc detect two gpu but seem to give same gpu two jobs, this makes crash one of the two jobs.

To prevent such crash, go to nvidia panel and deactive Sli switch, then, Boinc still recognize two GPUs and driver will give each job on each gpu chip instead of two jobs on same gpu.

Thank You all for answers.

Liveonc, my GPU isn't OCed, and my CPU is very well watercooled with 1st choice watercooling parts. With OCCt test that makes your CPU really burn (lingo test i think), my CPU T° stays, for the hotest core, at 57°C, wich is very well under such burning test.

I really don't think that's it's CPU related, but i made a new machine for test purpose, i investigate where is the problem.

At this moment, i can say that my doubts about graphic drivers issue under Seven 64 seem to be the problem. I reinstall a ghost of vista and no more errors with this OS.

Thank you Jeremy, my system is not as much overclocked than displayed (3.6Ghz), and all is tested "rockstable" since a lot of time. I did CPU burn tests, Gpu Burn tests, memory tests. All seems to be ok OCed or not, same computation errors with non overclocked system.

I just don't understand what happen, never had this problem before switching from vista 64 to seven 64. Maybe Gpu drivers related, i just don't know.

I disabled the Sli Switch and i'll give it a try for the next 48 Hours, thx for reply and help.

Hi guys, the title says it all, all my Cuda apps are crashing while computing.

I checked all my temps and i benchmarked my graphic card to see if i had a temperatures problem. No problem with my 9800 GX2 (running 80°C at 100 %usage), all is ok but boinc cuda computation.

I'm running Seven 64 bits and 196.21 Gpu Drivers under 6.10.18 Boinc Manager.

If someone could give me some help, thank you by advance (sorry for my poor english).

Apps which crash :
- Seti Cuda 100% crashing (no wu finished)
- Einstein Cuda 100% crashing (crash at the moment a second Gpu is active)
- GpuGrid 85% crashing Some wu 100% completed, not able to compute on both gpu, if i do so i get compute errors on all wus.

Works well with 190.xx drivers, and cherry on the sundae, you don't need to switch anymore in vidia control panel, on dual gpu boards, to make your two gpu run each a workunit.

Have 5-KASHIF_HIVPR_dim_ba1-4-100-RND6112_0 using acemd version 664 running since 21 hours on 9800gx2, 68% done, never had such long wu on gpugrid, usually i make like 3/4 wus in 21 hour. Hope credit will be as great as the time it takes to compute ;).

Try EVGA Precision on EVGA.com, not availaible for monitoring exact ressources GPUs are given, but a really interesting tool to monitor Temps and OC.

Thanx all for answers, i uninstall and reinstall the drivers and everything goes fine.

Hi all, i download these drivers today and find problem when switching to multi gpu to compute two Cuda units. Boinc still only see one Cuda device.
Anyone else with this probleme with sli our bi gpu card?


Ps : I'm under Vista 64 ultimate Os with two lcds plugs in.
