So if there is no link for batch 4 firmware where did you find the info?
That screenshot is from the bitmain firmware site; the file description next to the blank field is:
S9 firmware-20160608-650M
s9firmware-20160608-600M,12.93T
s9 firmware -20160608-550M,11.85T
The last line showed up most recently. Like I said - speculation, but it is pretty suggestive.
yeah and based on some reports about early batches and under clocks working I think the gear was a ting bit too hard on the
[antimatter < fuck you spell check]
antminer psu's . I had the feeling they would need to slow the clocks up based on heat from summer mining and the psu being rated a bit higher then it really is.
