Hi All,

I'm trying to get the 2 cards above working together in BOINC in the same machine

They don't want to

Boinc shows (not used) for the 550 ti - the drivers are correct, I have also added the <use_all_gpus> flag in cc_config.xml

Windows sees both cards OK, running driver 391.35 (nvidias recommended driver)

Any hints?

Thanx

The 550Ti is a Fermi card. NVidia stopped updating the driver for these cards a while ago (I think 340.xx or so). These drivers do not support the GTX 10xx series of cards because they were not out yet.

What is going on is that you have the drivers loaded for the 1070Ti, while the 550Ti is either trying to run on the NVidia driver that it cannot run on or (more likely) is running on the default windows driver that doesn't support OCL.

You are going to have trouble running these two cards together (maybe it will with PPS sieve since it is a CUDA app).

Thanx Scott,

Nvidia reckon that the 391.35 supports both the 550ti and the 1070ti - that's what I'm running.

I did have 398.xx loaded originally, but it didn't see the 550ti at all

Another thing you might try is to swap out the card locations. The driver might not pick up the 550Ti properly if it is not device 0.

Did you load the driver twice? Sometimes on windows pc's you have to load the software once for each gpu in the system, so while it worked for the 550Ti the software may not 'see' the 1070Ti until you load it again. the other problem could be you need a 2nd monitor plugged into the 2nd gpu or a "dummy plug" plugged into it. Here's a link to show you how to make your own "dummy plug" http://www.geeks3d.com/20091230/vga-hack-how-to-make-a-vga-dummy-plug/

If you use a 2nd monitor it only needs to be plugged in on startup as Windows does a polling of all the things plugged into your pc then and if it doesn't 'see' the 2nd gpu being used it will disable it. The 'dummy plug' means it always 'sees' a 2nd monitor plugged in as the plug provides enough resistance to do that.

Fixed

It was a combo of starting the PC with monitors plugged/not plugged in in certain spots!

Working until the next reboot!!!???
