Claymore's Dual Miner: Settings and statistics

[citronick]

I only set for ETH which is maximum -ethi 16
For any 2nd coin, I just let it rip and get the Nanos to work as hard as possible
because these Nanos are undervolted using the Heliox rom, and overclocked a bit.
So far these Nanos are heavily stretched but they run cool at 68-72c
So just let them fly....

Did you try play with -dcri too?

At value around 30-35 you will have about the same ETH mining speed, but higher ALT compared to pre-set values

power bill is my major concern.

I am sure -dcri 30-45 will further increase power consumption and heat.

Do you have a watt-meter? My 4x R9 390 + periferia give me 1320W from wall

Yes I use the watt-meter.
My ETH rigs are mining at home so there is not enough amps to go around.
Until, I find a way to send these rigs to join my BTC miners to outsourced DC,
need to underclock and undervolt as much as possible, to save on power.

Am I right that all cards are with stock settings?

The only stable change I can make is to reduce the power setting for each card down to -25%. When I tweak anything else, the stability is crap. I will swap the current 750W for my 850W tomorrow to see if that affects anything.  I've not attempted to flash the ROM on any cards.

I dont think it is a PSU issue - but keep us posting on the results

Basically if you have any of the old Tahiti based cards (7950,7970,280X) your highest profit will be at +DCRI 60.

Right now with the current diff, you will make +40% extra per day compared to mining ETH alone.

However,

It will use about 30-40% more power, pretty much the exact same amount of power as in the litecoin mining days. A single 280x will use 300 watts almost.


So depending on what kind of setup you got, it might be worth it for you. Its basically no different than buying a few more 7970/280x GPUs but you don't have to actually buy anything since it will use the exact same amount of power.

i have 31C outside in summer so its pretty hardcore, so im helping myself with external fan to blow off heat from rigs

Nice topic, i will post my settings later

[adaseb]

After much testings,

If you have a 7970/280x, you are better off dual mining SIA with that card than buying another rig with a RX480. Mining SIA with +30 intensity will make you about the same money using about 6.66W/Mhs when sold for ETH.

Basically its efficient to dual mine only rather than ETH solo mine and sell SIA for ETH/BTC.

This is only true if the SIA difficulty and price are stable.

hi willi - how many amps does this rig take? thanks

[willi9974]

my AmperMeter say 4,51 AMP
why is this information important for you?

[citronick]

my warehouse only gave me 63amps, 3-phase.

so i need to be careful on the watts and amps.

I am undervolting as much as possible - to save on power bill

But NOT so easy to undervolt 480s compared to 390s and Nanos.

How much electricity in Germany nowadays?

If you live close to Switzerland you can rent a warehouse with VERY cheap electricity

[willi9974]

at the moment i pay 28 Cent per KWh but after november i have a new contract with 19 Cent per KWh

i pay 0 for kW xDDD

Please put the statistics on your rig and hashing power
