Here are the power consumption increases with ETH only and ETH+SC
One rig uses 925Watts with ETH only and with ETH+SC uses 1100Watts.
Another rig uses 525Watts with ETH only and with ETH+SC uses 620Watts.
So exactly a +18% power increase.
Anyway to decrease ETH intensity while its mining? Basically want to reduce ETH speed so it uses the same power as before from the wall.
Yes its in the op.
-ethi Ethereum intensity. Default value is 8, you can decrease this value if you don't want Windows to freeze or if you have problems with stability. The most low GPU load is "-ethi 0".
Also "-ethi" now can set intensity for every card individually, for example "-ethi 1,8,6".
You can also specify negative values, for example, "-ethi -8192", it exactly means "global work size" parameter which is used in official miner.
