I'm looking for someone to help/explain something to me.

Currently I have a single Club3D Royalqueen 7850, and I'm looking to expand this by buying a Club3D Royalking 7850.

The difference between them is that the former has 1gb memory and the Royalking has 2gb memory.
How do I effectively utilize the extra gb of memory with a batch file?

I think I have seen something where they used commas to make this work (example: --gpu-engine , --gpu-memclock ,

Is this correct?
