the good unicorn is the first batch of T9. I have few and since running non stop. 2 of them once made 183 days straight.
So is the T9+ more reliable than S9? It is cheaper per TH for expansion and faster ROI at current prices?
Yeah I think it's the sweet spot for Bitmain in reliability...has less chips for less hash rate, but runs smoother.
I do not have S9 running. Only some remaining stable S7 which hashes just fine after the first few died out.
What do you mean by smoother?
Meaning it hashes days on end and chip status does not end up xxxxxx?
Fewer errors for the most part, and more reliable. Some of those s9's are horrific on their reliability.
