Phil and AriesIV10,
I switched all my 2 rigs to ETH. Mining ZEC gives substantially lower profit on my setups
Well for me with the lower volts and low clocks zec still works.
5 rigs 18 cards 2.3 to 2.4KH of hash
7.7 x 240 volts = 1848 watts
every fan at 50% = pretty quiet
monthly kwatts are 1376.4 x .127 cents = 175 USD for power
earn .3 zec a day x .095 = .0285 btc a day x 745 = $21.23 x 31 = 658 usd a month - 175 power = 483 profit.
I figure the heat is worth about $1.50 a day so add back 45 and I am at 528 profit per month
Eth would earn more but I would burn more power higher fan speeds.
I like a four card rig near 400 watts
I like a three card rig near 300 watts
This power savings make the hobby easy to do.
I still point a four card rig to Eth but it uses 580 watts vs 400 watts.
I am not sure I could get the rigs to drop power on eth like I can on zec
