After running ETH farm for nearly 2 years now.... I learnt an important lesson, esp if you have 20-30 rigs farm.

Rule No 1 -- always under clock, and under-volt (modded ROMs for low power higher hash if necessary)
Your gear will last longer this way.
Substantial savings on power bill too.
You can manage the cooling solution better.

Rule No 2 -- never dual mine otherwise hell will break loose sooner or later.
Sure you get a few more bucks for the 2nd coin.... but the RX isn't really optimized for the 2nd coin in Claymore's list.
When the profitability is better, I usually get my non-RX rigs, like Nanos and 390s, to mine DCR, ZEC and others directly

Rule No 3 -- always use the best card for the best coin type.
While all my AMDs are ETH mining.... all my 1080tis are mining exclusively ZEC, because simply NVIDIA cards are very good for ZEC
