You do have a Cuda app in your app_info?, as Boinc 6.10.18 will still ask for GPU work even if you don't have a Cuda app referenced,
as all your optimised results are CPU results,
Go grab the 64bit installer and the Cuda 2.3 DLL's,
Shut Boinc down, install the SSSE3x or SSE4.1 (SSSE3x better on a Quad, SSE4.1 maybe better on a Dual Core),
make sure you also select the Astropulse_v505 app and the Cuda V12 app,
when that's done over-write the Cuda dll's in your Setiathome project folder with the new Cuda 2.3 dll's, then restart Boinc,
touch wood you won't loose any CPU work.
Edit: you're got a lot of lost 6.03/6.09 work, so it might be better if you go to your Seti project preferences, select the following to No:

Use CPU
(enforced by 6.10+ clients) yes
Use NVIDIA GPU if present
(enforced by 6.10+ clients) yes

Click update, Now Detach and Reattach (you won't be sent any 6.03 or 6.09 work, so you can't loose it in the next step),
then install the apps with the installer, and the dll's, reset your Seti preferences to yes, then click update, and hopefully you'll get work.

Claggy

Edit: If you get Astropulse_v505 wu's, it'll help keep the wu count down a bit, and probably help Boinc's performance with lots of wu's.

Hi, I followed the above instructions when I added my 3rd GPU card but my Boinc still only sees 2 cuda cards. Windows and GPUZ and nvidia control panel all see a GTX 285, GTX 275 and the GTX 260 I just added but boinc only sees

Can't get it to see the GTX 260....

Do you have the cc_config set to use all GPU's?


--- Code: ---<cc_config>
    <options>
        <use_all_gpus>1</use_all_gpus>
    </options>
</cc_config>
--- End code ---

hiamps:
Yep, I have 2 working just can't get the 3rd even got a new 1250 Watt PS today. Here is my cc_config...

<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
<report_results_immediately>1</report_results_immediately>
</options>
</cc_config>

Dummy plug, screen extended?
