Information About GPUs.txt File

Postby PantherX » Sun Apr 20, 2014 12:58 am

  • 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 and the changelog can be viewed here. For technical details, refer to this page. 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 system (copy).

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

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
