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.
http://imgur.com/a/i2JmUThings are even better pool side.
What cards and core/ram settings if you don't mind sharing?
My modded 470/480s and 570s do only 650-750 with Claymore and 1500 modded bios.
Modded 460 around 400, unmodded 460 around 350.
470 & 480 with Samsung memory. Custom 1750 straps for eth. Stock core, memclock between 2100 - 2200. Undervolted.
I had just switched from eth to see what speeds I'm getting and then just let it be.
Try with sgminer-gm.
