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 ?
Hmm, that is interesting indeed. I have a few batch 4 (I think, I'd have to double check) and they hash at 440 to 450...except one which is hashing at 413 for some reason - likely the chips on either one of its blades are likely a lower bin quality or something?
But for sure they are refining the design along the way. Batch 8 units are expected to hash at 500 GH.
