Using 6 units of RX480 8GB, i noticed that if I mine ETH only, i can get a total of speed of 130Mh/s.

If i mine both ETH and Nicehash, my ETH speed is only 115Mh/s.

Is this expected?

HI,

Im very new to mining...

I currently have 3 mining machines, all using Claymore mining 9.3 GPU

Should I:
1. create a pool using one of the machine, and point the other 2 mining machines to the pool, OR;

2. just have all 3 mining machines pointing to the us ethereum pool?

If I should go for #1, can I use p2pool.com together with claymore mining 9.3?

Thanks!!
