Hi Claymore,
VEGA64 cards?
"-a 1" ?
1. "-powlim 50"
2.
-a algorithm mode for Ellesmere cards (RX470/RX480/RX570/RX580 cards), for other cards always "-a 1" is used. You can specify "-a 1" (default) or "-a 2" and find the best hashrate for your card.
You can also set this option for every card individually, for example "-a 1,2,1".
As you can see, "-a" parameter is for Ellesmere cards only:
-a algorithm mode for Ellesmere cards (RX470/RX480/RX570/RX580 cards), for other cards always "-a 1" is used.
So don't specify this option for Vega, it won't change anything. You can use "1" for Vega in rigs with mixed cards.
