Hello all!!,

Love the program, have it loaded on 3 home machines.
On my personal desktop i use the following cards to achieve a 3 monitor setup.

Win7 64bit fully updated.
Main GPU = XFX 5850 1GB
Seconday GPU = XFX 9800 GTX+ 512MB

So, both the bundled control applications (CCC and Nvidia control center) work on their associated screens/cards.

All games and applications work and recognize the cards properly, other than boinc.


Boinc thinks that the ATI GPU is missing, but sees the 9800.

You don't say what version drivers you're using, you could try Cat 10.9 and see if that fixes this issue, not tried it myself yet,

or you could try this work around:

Main GPU = XFX 9800GTX+ 512MB Black Edition
Secondary GPU = XFX HD5770 1GB

"Win7 64bit fully updated."
I should not have been so succinct.
A problem i have, lol. ;)


Info from device manager

ATI Driver

The Ati driver is the newest Beta (allowing me to AA in Starcraft 2)
The nvidia driver is a core stable one.

Love the setup, how do you run games? through which video card?[/quote]

Games are run through the 9800GTX+, the HD5770 doesn't have a monitor connected to it, and is only used for crunching, Seti mostly,
I'd swap the cards physically around on my M/B, but there isn't enough room for the 9800GTX+ in the bottom slot, SATA connections being there too.

I am having this issue as well, though with somewhat older cards:

Main: ATI Radeon HD 3870 (Catalyst 10.12)
Secondary: nVidia GeForce 8200 (Release 266.58)

Windows 7 32-bit
BOINC 6.10.58

I was using the ATI GPU for awhile and decided to fire up the integrated GPU since it wasn't being used for anything else. After installing the drivers and rebooting, BOINC states the ATI GPU is missing:

"1/23/2011 3:35:59 PM Collatz Conjecture Application uses missing ATI GPU"
"1/23/2011 3:35:59 PM Milkyway@home Application uses missing ATI GPU"

Yes, and? Your question being what, exactly?
Or are you just stating the fact that your ATI GPU is no longer being seen by BOINC and that you know you need to fiddle around with the drivers, to see which GPU you should install first and which one last, for everything to work?

As that's what you'll have to do. Your enabling of the 8200 (which according to Nvidia's pages isn't a CUDA capable GPU, so I'm not sure what you expect from it) probably screwed up the drivers balance on your system and you'll just have to bring it back. Nothing any of us can do a thing about, but for cross our fingers and hope you can do it.

Of course, if you were looking for help but just had to post about this in an older thread, without reading any of the posts in that thread to see if any of them held your solution (like Claggy's post for instance), then uh... well, good luck.
