I cant get GPU job for this project
What is problem ?
Any solution ?

If your GTX285 isn't too old to run the project. Don't know that card so I cant say. Biggest thing I see is no OpenCL driver listed, may need to update the drivers.

I run PrimeGrid which also need OpenCL, example is
Generalized Fermat Prime Search n=17 Low (GFN-17-Low) Nvidia GPU (OpenCL)

Maybe is my graphic card too old fot that project.

Milkyway's GPU requirements are posted here. https://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=3188#57810

Your card is listed as supported but it could just be a driver issue. Sometimes I have to upgrade or downgrade a driver to get a Boinc project to work.



This is a clip from the posted link:

Milkyway@Home requires a GPU supporting Double Precision arithmetic and OpenCL 1.0.

- Most new cards (year 2012+) should work. If they don't it's a bug, as some driver versions are broken. Many of the broken versions have workarounds.

NVIDIA:
- Requires Compute Capability 1.3 and Above.
- For the GeForce 2xx series, this is the GTX 260 and above.
- Any Fermi based (GeForce GTX 4xx or 5xx) should support doubles.
- Any older GPUs (such as a GeForce 8xxx or 9xxx) will not work[/url]

Make sure Windows 10 didn't automatically update your driver to something that doesn't work. Uninstall and manually install correct one from Nvidia.
