Phil.... run ccminer/cryptonight instead -- I think NH pays higher rates now vs equihash.
use the skunk build v2.2
crytonight even lower power and less heat are bonus
Did you move your amd farm to monero?
If so, which miner are you using if I may ask. I'm getting over 800h/s per card with sgminer-gm.
