Topic 225394

I have searched and searched, and am sure the answer is here somewhere.

Would anyone know how I can get E@h to use both of the GPU cards in my computer?

Thank you.

If they’re the same model of

If they’re the same model of GPU, there’s nothing you need to do. 
 

if they’re different you need to add this line to your cc_config.xml file 

<use_all_gpus>1</use_all_gpus>

Without telling us what two

Without telling us what two GPU cards you have try:

                                  
  <cc_config>                                       
             <options>                                   
                                                                                                           
                      <use_all_gpus>1</use_all_gpus>           
                                                       
             </options>                                 
  </cc_config>   

 

Place it the BOINC Program Data file using the name "cc_config.xml".

Create the file, if not already present, with "Text Document"   AND  changing .txt to .xml while saving the new file. Then edit it with "Notepad"

 

It is all explained in the docs ...

Thank you.

Here is the message I get when I start BOINC.

The cc_config.xml is either

The cc_config.xml is either incorrectly formatted with unseen extraneous characters or the file type was saved as text and not .xml.

The file is not being read to pick up the new command.  Verify the filename is exactly cc_config.xml and then try restarting the PC from scratch.

I'm wondering if those "dashes" in column one are actually present in your source text?

If so, delete them ...
