Cast XMR GPUs show incorrect status
If cast-xmr is using a sub selection of GPUs instead of all the GPUs present in the system the power and hashrate stats will be skewed. This is caused by a difference in agreement of how compute units should be indexed. Because mining software does not identify each GPU there is no way to tell how many units the miner is using vs what exists on the system.
-G 0,1 tells cast-xmr to use compute units 0 and 1. However, there are three units that exist on the system.
