A new version of the GPU folding@home clients have been released
YOU MUST INSTALL THE NEW VERSION. THE BETA CLIENT IS SET TO EXPIRE ON DEC 1
x1600 and x1800 cards now supported!!!
The dual core client for those w/ dual (or more) pci-e 8x or 16x setups
Download
Configuration
Work units are now 330 points each! The x1900xt running at 2D speeds should now be able to fetch 660 points per day!
I will be updating this thread frequently with updates. The big release is set to be in the afternoon, PST.
Feel free to post any questions or comments you may have.
Hardware Requirements:
1.) ATI Radeon X1600, X1800, and X1900 Series
2.) Just in case you haven't heard, no NVIDIA support at this time. But will be sometime in the future with G80+ cores
Installation
1.) Drivers need to be updated to min 6.10 drivers.
6.10. If have issues with drivers, use
DRIVERCLEANER then reinstall drivers.
2.) Install DirectX: 9.0c (4.09.0000.0904) or later.
Download
3.) Install the Windows GPU Folding@Home client.
Download. Both GUI and console options are available. It looks like better performance will come from the console version. They are currently working on the linux GPU client. No ETA.
Configuration
1.) Follow the on-screen prompts.
2.) Just keep in mind we are team 198
3.) Should not run as a service for now.
4.) Say yes to allowing workunits above 5mb
5.) Adv settings you want CPU usage to low and the next option to 100.
6.) Set the Machine ID to 2 or 3 as to not worry about causing issues with other cores. (if you have them)
Running the Client
1.) You are not "suppose" to run multiple clients with the GPU as of now. If you have a dual core machine you may run one GPU client and one CPU client. Just make sure they have different machine IDs! This can be done during setup or by editing the client.cfg
2.) The PPD on a normally clocked x1900xt look to be around 660 PPD.
Maximizing Performance
Force 3D This looks to be about a 1/3 increase in performance from the defualt settings! <-- Thank to HardOCP for these.
1.) Disable ATI Pooling Service
LINK
2.) Force 3D mode with ATITool
Download
Maximize Results on a Dual Core System
1.) Install ONE service of the console cpu client
2.) Set to 100% utilization at idle.
3.) Setup the GPU client to use 100% at low priority. Remember, do not install as service for now.
Notes
1.) This project is still in ?beta? but the Pande Group (the ones behind F@H) said everything should run go smoothly; only polishing of the client needs to be done.
2.) Shut down F@H for your GPU before opening any 3D apps. The switch from 3D to 2D mode can crash your machine.

Notes for running
1. The GUI client will slow down the scientific core (since both use the GPU heavily). We do not recommend the GUI client for long term use, unless you have two graphics cards.
2. Multiple GPUs are currently not supported (but will be supported in future releases); Crossfire is also not supported -- Crossfire will make FAH run more slowly than using a single GPU (this isn't a bug as much as a fundamental issue regarding the nature of a Crossfire/SLI type architecture).
3. The GPU client is not meant to be run in the background while one uses the computer for applications with heavy GPU usage -- it will greatly slow down the response of programs which make heavy use of a GPU
4. Do not run multiple GPU clients simultaneously -- there will be a huge (non-linear) slow down in performance. We currently do not support multiple GPU configurations, although a second GPU can help speed up the graphics of the GUI.
5. Client looks like it is using lots of CPU time: Graphics drivers must poll the GPU to see if it is done. This will look like a lot of CPU time being used, but nothing is really being done, so one can run other relatively CPU heavy code at the same time. However, we do not recommend running multiple FAH clients, as this can significantly slow down the GPU client.

Known Bugs
The GUI pause core command doesn't work
The GUI Client will automatically quit when running fullscreen directx apps (games), it may be a little slow at doing this though
In some rare situations, one needs to set the Hardware acceleration to max if the Catalyst install didn't do this. To do this, go into the Display Properties/Settings/Advanced/TroubleShoot tab and double check that the Hardware acceleration was set to "Max".
Known compatibility issues
One must use specific Catalyst drivers (6.5 or 6.10) and a recent DX version-- see the HOW TO above
The GPU core does not run under WINE in linux (nor do we have plans to support WINE)

Trouble shooting EUE's
Some Alpha testers have found an excessive number of Early Unit End's (EUE's) -- we have not reproduced that at Stanford or ATI and we need help from beta testers to help track this down. If you see many EUE's (i.e. more than 20%), please make a post in the GPU section of the forum with your system configuration (ATI driver version, DX version, OS) and hardware (card, CPU, motherboard type). With the help of beta testers, we hope to nail down what's going on.
If you are seeing lots of EUE's, please download the ATItool application and check that your core voltage is set to 1.4V. This has been shown to lead to problems.
Policy Notes
The client will stop working after 2 months (this is a limited release beta -- new clients will be available before the current version ends its test period)
Deadlines will be set to be much shorter than normal, as we need to get data back quickly in this beta test and we are releasing to a very specific set of hardware. This will likely change in time, as we move from a beta test and as we move towards supporting other graphics cards.
