Nvidia and ATI in the same box

[Mr. Hankey]

So I did the card swap under the house... I now have an Nvidia GTX 260 (card 0) and and ati 5850 (card 1) in the same box... but boinc does not see the ATI card. Both cards have a dummy connector and the OS sees both cards and the desktop is extended across both cards.

cc_config options look like this:

    <options>
<zero_debts>1</zero_debts>
<use_all_gpus>1</use_all_gpus>
<dont_check_file_sizes>1</dont_check_file_sizes>
<report_results_immediately>1</report_results_immediately>
<http_1_0>1</http_1_0>
<max_file_xfers>40</max_file_xfers>
<max_file_xfers_per_project>4</max_file_xfers_per_project>
    </options>

and when boinc starts up I see this:

Any ideas? TankMaster you were running an ATI/Nvidia setup correct?

[Maxwell]

If I remember what Tank said when I asked about this, he had the ATI card in slot zero, and did NOT have anything plugged into the Nvidia card. This was under Win7.

[Mr. Hankey]

Well I can try swapping them. The nvidia card used a dummy plug before I added the second card in so that shouldn't make a difference. I am running win 7.

[Maxwell]

Tank said that he could only get tasks to run on the NVidia card without anything plugged into it when he had the mixed cards in the same box.

Up until a few days ago I was running one of my 8800GT's alongside my HD 4850 in my i7 box w/Win7. Never had an issue. I could run any nVidia app that worked with Compute Capability 1.1.

Notes:
OS: Windows 7 Home Premium x64
ATI Driver: 10-12_vista64_win7_64_dd_ccc_enu.exe
nVidia Driver: 260.99_desktop_win7_winvista_64bit_english_whql.ex e
BOINC: boinc_6.10.58_windows_x86_64.exe
OverClocking Utility: MSIAfterburnerSetup200.exe (Works for nVidia & ATI)

I did not extend the desktop.
I did not use a dummy plug on the 8800GT.
I also did not add anything to the cc_config.xml file.
I did not run the cards on the same project. I had the 4850 on MW and the 8800GT on PG.

This is the same problem i had when i first got back on the boards. Computer hadn't been connected to the internet in 3 months, so it had a few dozen updates to do. Before and during the updates, everything worked fine. After the updates, BOINC never saw the ATI card, but the Nvidia card worked fine. I changed the ATI driver all the back to 10.7 and nothing helped. Changed back to an old BOINC version. Nothing. finally i just had to restore the computer from a previously saved point. Then everything was fine. Not one deail about my computer changed, except for whatever updates were downloaded, which included drivers, security updates, etc., so i was never able to pinpoint what the exact problem was :/

[John P. Myers]

Got it. Was the ATI driver. Just tried installing 10.12 APP again and it broke everything. Went back to 10.6 and everything is fine.

[Mr. Hankey]

Swapping slots seem to do the trick... guess the ATI card doesn't like not being in the first slot when an nvidia card is in the box too. Also looks like nvidia cards don't need the dummy plugs or the extended desktop.

Crunching away 8 cpu threads, 1 nvidia and 1 ati....

I am running ATI 10.12 and Nvidia 260.99

Not sure if this is your situation but my 4850 does not like the APP drivers. And though it works with Cat 10.12 w/CCC I cannot crunch 2 wu's consecutively on a card. I may roll back to 10.10.

Glad to hear things got sorted out. Crunch on!!!

Not to be "that guy" who resurrects dead threads, but I find it nice when old threads on the boards are helpful in solving problems. Yay!
