I think you mean the k version is bad not the j

From what I have read on other posts I think the same. S9 and j versions I think are ok, but I NotFuzzyWarm has a different experience.

Philipma1957 what is your view on the above questions as someone who has mining experience and knowledge?

They would run good with brains +

down clock to 13th and lower power.

or auto tune at 1100 watts a miner.

They simply don't break at 1100 watts and they do break at 1400 watts.

If you can get them with psu's for 300

1 unit doing 12.8 or 13 will earn 3.80 a day before power

1100 watts = 26-27 kwatts or 1.62

so 3.80-1.62 = 2.18 a day you need 138 days. you could start to sell them at day 100 in lots of 10 if you could still get the 300 for them. it would hasten over all roi.

If I had the power and could afford to lose 90 x 300 = 27k - 15k = 12k I would take a shot.

as I think worst case would be a 10k to 12k loss and a huge fail has to happen to go that bad.

You are the man

Thanks a lot, crystal clear and concise.
Would you trouble to overclock them with immersion cooling?
I understand that immersion has to come after 100th day since if I decide to sell there will be no value for them if they are immersed.

I do not have any immersion experience.
As you say make some money back for a while.

At day 100-140. Sell ten and immerse ten. My logic would be you get to learn about immersion and how much it works or does not work.

Maybe down the road you get a better deal on better gear and you already have experience with immersion so you know you can do it or you know it is too much of a hassle..
