Is SLI disabled?

OT:
You could also upgrade to BOINC 6.3.21, it has some fixes for scheduler bugs...

I've tried disabling the sli, it doesn't work.

I switch back to 6.3.19 because of some bugs (it download like 15 days work buffer) but it was the same thing, i had only one cuda detected.

What's BOINC saying?

10/11/2008 22:35:59||CUDA devices found
10/11/2008 22:35:59||Coprocessor: GeForce 9800GX2 (1)

?

With VISTA you have to have the desktop extended onto the second GPU.

See http://www.ps3grid.net/forum_thread.php?id=379&nowrap=true#2487 or the other threads that discussed this.

Yes that's what it shows, one cuda present.


Must i have a second monitor plug in to extend my desktop?
