who tells us that buying antminer s7 batch 3 (4.86 th / s

They send antminer s7 batch 2? (4,66 th / s)



amount of chips are equal, the difference is in default frequency

575 MB vs. 600 MB?

so if I buy the second batch, and put the firmware of batch 3? I can do it?

Since the amount of the chips are equal?

correct me if I'm wrong.

You might merge this with the other S7 thread as it is not really needed a thread of its own.   But that is up to you.

As far as who tells you it would be bitmain.  You would get a email if it's like batch one and they asked if it was ok to send a lower speed miner.   But I suspect with different batches they do pretty good at getting the right speed to people that order.

Not quite sure why you are raising this in a new thread as it's all covered in the main thread?

However it's not a firmware issue, all batches 1,2 & 3 can be run at 600MHz or 575MHz. The issue is that some units, Batch 2,  Bitmain have decided to derate to 575MHz presumably because the HW error rate at 600MHz was unacceptable?

rate of hardware failures? same materials, same amount of chips,? assembled by the same people? but what you're saying?You tell me how do you to realize if they send you after you buy 2 batch 3 batch? that the difference are 20 gh / s?



PS:  do not worry about the thread, you can quit at any time

[Tupsu]

... that the difference are 20 gh / s?



PS:  do not worry about the thread, you can quit at any time

Why do you feel concerned about it, if the difference is only  20 gh / s ?

Your math is terrible. Make yourself clear , how many GH/s is in one TH/s.

The best you can do with  your thread,  is to put it in the lock.

batch 2   4,66 th/s

batch 3   4,86 th/s


what is the difference?

[SunnyIgor]

Will batch 1 (still waiting ) at least be the 4.86?
Because i heard some were getting commpensation because of only 4.66...

[notlist3d]

batch 2   4,66 th/s

batch 3   4,86 th/s


what is the difference?

The difference is some miners under preform.  It was enought that it did not fit in standard +/- of hashrate.  So... they split it into two batches.

One is cheaper and slower.  Other is higher and faster.    Some in batch one got the slower and got a little compensation.   But speed is the difference along with price.
