So I've just updated my drivers to 359.00.
Halfway through crunching a few work units.

Now BOINC can't find my cards.
Hope this doesn't happen to everyone.

Any advice?

The recommendation is to finish tasks before installing drivers and to restart the system afterwards.
Suggest you restart your computer again; Boinc likely started before the drivers finished updating when you rebooted for the first time.
Did you install Boinc as a service?

Thank you SK Given, Boot order was a very good idea, but it didn't work in my case.

I restarted the computer, and I'm seeing the same error.

Just to confirm, I'm not alone in having new drivers, right?

I haven't installed BOINC as a service - my GPU grid tasks were running just fine before, and they're halfway done.

Also, what's up with this?
Peak GFLOPS for 970 is supposed to be 3494.

Hi,

I have just installed the 359 driver on a GTX970 and works fine.

May I suggest you reinstall the 359 driver again but over the top NOT a clean install because you have dual cards and when I ran dual cards sometimes had to install driver twice. I did actually post this in this forum for someone else who was having problems. I checked his output and they were all fine after that but he never did post back as to whether it was that, that had cured the problem. Make sure you suspend GPUGrid before reinstalling drivers.

A clean reinstall did the trick. The first of the stuck results has validated.
