what batch # is this ?
It does not matter, they are all the same.
Incorrect, my b#1s don't hash the same as my b#5
Really? Hmm, interesting. What is the difference in performance?
b1's 380 - 420 i have 5 of them all the same
b5+'s 450 - 490 i have 5 of them as well
something bitmain is not telling us ?
