Since the public release of the Folding@Home client for modern ATI GPUs several issues have come up. Some of them are known and included in the GPU FAQ. Others are being discussed in the [1] Folding-Community support forum.

If you have an issue which is not reported yet, please report it on the Folding Forum.


Supported Graphics Cards

GPU1 client: ATI x1600, x1800, and x1900 class (discountinued June 6, 2008)

GPU2 client: ATI HD2xxx, HD3xxx class, HD4xxx and later (Anything with CAL support in the drivers.)
_a_n_d____: All nVidia 8xxx class GPUs and later* (Anything with CUDA support in the drivers.)

  • Note that nVidia cards with less than 256MB of video do not have support for CUDA

GPU3 client: v6.31 console and v6.32 systray clients, and Fahcore_15 released to open beta 05/25/2010. Added support for NV GTX 4xx GPUs. New FAQ: NV GPU3 on FAH web site. Link to environment variables for Gpu client: [2]

Will earlier ATI cards such as the 9600PRO ever be supported?

No!

The short technical answer is that those boards do not support looping constructs 
and are also 24-bit precision which is a problem for us. The X1K boards were the 
first to support 32-bit precision and branching/looping on the ATI/AMD side of the world.

Known Issues

  • If Windows enters the "fast user switching" screen the GPU core will quit. Solution for now is to turn off the screensaver going to login screen.
  • Doing a 3-finger salute [ctrl][alt][del] to bring up the task manager will also cause the GPU to exit. Solution: right-click on the task bar then click "Task Manager"

Note: The GPU2 clients based on CAL and CUDA have resolved many of these DX9 context based errors.

Version Info

Please note: the version info below is a future roadmap for cores and not all cores are publicly available.
