How to mine on multiple GPUs

You need to set the size of the page file to at least 4 GB x number of GPUs you are using. So for 6 GPUs you can set it to 30 GB.

You can start the mining on multiple GPUs with the following RPC commands. If you are using the GUI version of the wallet you can enter the RPC commands under Help/Debug/Console. If you are using the command line version you can use "bitcash-cli xxx" to execute the command xxx.

Do not need to click on the start mining button in the GUI version to start the multi GPU mining, you only need to enter the RPC command. If you want to see the cycles/second in the GUI you can first click on the start mining button and then enter the RPC command.

To start mining with multiple GPUs:

setgenerate true false [true for GPU mining] [ID of first GPU] 1 [number of GPUs to use]

For 2 GPUs:
setgenerate true false true 0 1 2
For 4 GPUs:
setgenerate true false true 0 1 4
For 6 GPUs:
setgenerate true false true 0 1 6
The last number is the number of GPUs to use.

If mine on multiple CPUs you can use this command:

setgenerate true false false
To see how much mining power you have you can use:
bitcash-cli getmininginfo
If you are getting a high amount of graphs/second but a low amount of cycles/second something is wrong. Please check the file debug.log in your data folder for error messages.
