Re: Launching the Antminer L3+, World's Most Powerful and Efficient Litecoin Miner
I'd say what is my 'thumb rule' with almost all asics, below 90C to avoid miner failure and below 80C for longer life time.
okay then at the under clock my gear is great.
I should have ordered these sooner.
6 of them is only 6 x 725 = 4350 watts
at the underclock of freq 344
fans set to 35% running at 2,640 and 3,540 this is bearable.
I can run six of them on a single 30 amp pdu as 24 x 240 = 5760 watts and I will be at 4350 watts
Why would you underclock them, if they are very stable OC?
I run mine on 580-590mh for months without a problem so far. Just saying, temps are under 65°C, Fan speed 95% or so, nothing to complain about
Maybe for better power efficiency and/or lower ambient temperature it is worth to underclock it.
I have mine running in a tiny room and ambient temperature rises quickly, which in turns rises the temperatures of the miner.
At stock frequency I had around 70-75 degrees for the highest temp Chip, which while it is under 80 it is not good for its life time.
Now I underclocked at 350 where I also get around 455Mh/s and the highest chip temp is around 60-65.
Fans set at 3300rpm (wont go higher because of noise).
