1 - About GPUs.txt File

The V7 client requires a list of GPUs against which it can check if the detected GPU is supported or not. This is done by using a GPUs.txt file. The GPUs.txt file is a "greylist" since it is a whitelist (specifies which GPUs are supported) and a blacklist (specifies which GPUs are unsupported). With the latest Public Release (V7.4.4), the GPUs.txt file will be automatically updated every 30 days. In an event that it fails to update on the first attempt, it will automatically attempt to update it until it is successful.

The latest version of the GPUs.txt file can be found here. Please note that modifying the copy of GPUs.txt file on your system will not be useful since the master file on the Server isn't modified. In order for F@H to utilize the GPU, it should be approved (whitelisted) on the Server (master) and the Donor's copy will be updated on your system.

NOTE:While all this is true, Video drivers and OpenCL drivers MUST be installed before FAH will use your GPU. We strongly recommend that you download them directly from the vendor''s website. (nvidia.com or amd.com) For NVidia, the OpenCL drivers are automatically included. The default drivers from Linux, Intel, Microsoft, etc. will not work.

3 - Adding A Graphics Card To GPUs.txt File

The GPUs.txt file is updated whenever possible by the volunteers. However, if you happen to have a GPU which is supported (Windows, Linux, OSX) but isn't present in the GPUs.txt file, you can follow any of the methods below to add it to the GPUs.txt file.

Before you do anything else, determine the hexadecimal device code for your GPU and see if it's already in https://apps.foldingathome.org/GPUs.txt

Method 1 (Windows)
1) Download and run GPU-Z
2) On the Graphics Card Tab, look for Name and Device ID and note it down
3) Create a New Topic here and post those details from GPU-Z along with a copy of the log file
4) Once it has been confirmed to be a valid entry, the GPUs.txt file will be updated on the Server
5) After the GPUs.txt file has been updated on the Server, locate the GPUs.txt file, delete it and restart the Client
6) The Client will automatically download the latest copy of GPUs.txt file and your GPU should be supported

Method 2 (Windows)
1) Navigate to C:\Program Files (x86)\FAHClient or C:\Program Files\FAHClient
2) Open a Command Prompt window
3) Type fahclient --lspci and hit Enter
4) Copy the output
5) Create a New Topic here and post those details along with a copy of the log file
6) Once it has been confirmed to be a valid entry, the GPUs.txt file will be updated on the Server
7) After the GPUs.txt file has been updated on the Server, locate the GPUs.txt file, delete it and restart the Client
8) The Client will automatically download the latest copy of GPUs.txt file and your GPU should be supported

Method 3 (Linux)
1) Open the terminal
2) Type cd /usr/bin and hit Enter
3) After the directory changes, type FAHClient --lspci and hit Enter
4) Copy the output
5) Create a New Topic here and post those details along with a copy of the log file
6) Once it has been confirmed to be a valid entry, the GPUs.txt file will be updated on the Server
7) After the GPUs.txt file has been updated on the Server, locate the GPUs.txt file, delete it and restart the Client
8) The Client will automatically download the latest copy of GPUs.txt file and your GPU should be supported

A sample output of the fahclient --lspci command is shown below (may vary depending on hardware and OS):
