Just doing some catchup on my reading, since a number of us here at Phil's thread use Nicehash... pls read

How will the possible Bitcoin UASF, BIP148, BIP149 and SegWit2x affect you2017-06-19

@Marvell1

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

Very good info, you are right I had around 40 nanos dual mining dc all of last year and only 20 of them are still alive, on the RX cards I have only fried a few so i dual mine with the higer end 480s
but you are right i can tell the cards are dying slowing due to the summer heat.

My question is why do you care if they die ? I just RMA them since they are only 1 or two years old ?

on 3) yeah you are right Nvidia is way better on ZEC but I have found dual mining with 1070s and 1080tis is basically close to a wash in profitablity since the 1000 series does not really use much more power dual mining
compared to the RX cards ?

That being said my 20 remaining nanos are stil dual mining SIA and Eth, mostly because I cant downgrade my drivers to mine ZEC , I have 20 i need to RMA though I keep putting it off.

All my Nanos are on ZEC with Optiminer v1.7 Linux / smOS
Optiminer has optimized it specifically for Fiji cards.
Dont waste the HBM1 memory on the Nanos on ETH
That memory type runs great on ZEC algo just like Pascal cards
having said that -- caution for Vega HBM2 users and ETH mining
you may be disappointing in the results....

This is just my mining guide nothing perfect but it keep the farm straight... Grin

Always have test rigs to experiment and leave the other rigs make coins

RX and GTX 1070/60 cards -- always ETH
R9 and GTX 1080ti cards -- always ZEC

Of course you can use RX to do ZEC but it will do lower hash vs a R9-390 for example by a big margin.
You can do 290 for ETH too but will use more power hence not efficient vs a RX580/480
Also using an array of 1080ti for ETH mining is impressive but not practical because its too expensive -- an RX580/480 rig can do the same job at half the price.

As far as ZEC is concerned see below -- I have tested so many combinations and standardized these to the farm.

1. EWBF ZEC is best for GTX cards

2. Optiminer ZEC is best for AMD cards on Linux

3. Claymore ZEC is best for AMD rigs on Windows.
