Hi,

I'm only seeing 2 GPU's not 4 (when running 2 x GTX295's).

It's running the current version of boinc and the lastest nvidia drivers. I've got dummy loads on the 3 video outputs not connected to anything, and Win7 shows 4 monitors active. I don't have SLI enabled.

What should I change to use the missing 2 GPU's?

Thanks,
Far

Please give actual version numbers, if at all possible, rather than saying "the latest". Things move so fast in both the GPU and BOINC worlds that someone looking at this thread even a few hours later could get a misleading impression.

For instance, you are running BOINC v6.10.18 at the moment. I've already moved on through v6.10.19, and I'm currently running (testing) v6.10.21. There'll probably be a v6.10.22 later today.

These particular later versions address other problems, and won't affect your GPU count - I'll leave that for the multi-GPU specialists to think about. This is just a heads-up for you, and anybody else, reporting problems: I hope you see how easily confusion can arise.

From reading the un-offical changes by Jord it looks like the changes are around logging and cosmetic stuff.

v6.10.19 has a significant change for multi-threaded applications, so it will be relevant for this project when the multi-core CPU Beta gets off the ground.

v6.10.21 is mainly just extra logging in the Windows context - to help track down some residual task-switching and work-fetch issues. But I believe there are some more important fixes for Macs.

v6.10.22 will add considerable extra fault-tolerance for projects who use multiple download servers.

The machine has ended up with bigger issues, it's not stable..

When I work out what's causing this I'll repost with the version numbers.

Do a backup, then...
If hardware issue, usually best to start with a RAM tester, then do a disk check.
If Virus/Malware, pop the drive into another system, with good security, and sweep it, also good for a disk check!
If driver, Last known good configuration is a good place to start.

Good luck,

Was chipset drivers = now running correct win7version (my bad).

Thanks for suggestions.
