Can we allocate only a portion of each of two cards. For example, I have a RX VEGA and an RX 460 using ethminer.exe. I cannot find any description of the commands and what they do nor what parameters are used for ethminer.exe.

I want to run my VEGA say at 70% and my 460 at 100% for mining. Is this possible? If so how? If not possible, how do we limit the amount of the GPU used for mining for our setup by lowering the system to say 70% of all GPU's. My VEGA GPU gets hot and I want to cut down on its power when I leave it running so it doesn't get damaged. Thank you.
