ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH

[aurel57]

I received my first B1 09-09-15 order on Monday and it has been running 4850 since I connected and booted up. That is good.
I am not complaining by any means, but it would have been nice for Bitmain to share what the issue was which held off shipping.

.0021 HW error in a bit over 48 hours.
Temps at 54 - 60
power at the miner connection is 12.17 using a single 2880 to power the S7, along with an S5.

I am eager to see what an S7+ brings to the table along with other competition.
I do believe we will see other miners available, and I would like to see a 16 - 20 TH miner from someone with either prior successful sales to members we all know on this forum.  Say Phil for example. OR, they better begin building trust through transparency ala sidehack and novac.

I hope everyone see's their B1 S7 units ship by the end of this week so bitmain begins shipping the other batches.

While Bitmain lost serious points with many people for handling this situation the way they did, of course many will run to buy anything they sell. Personally it was a big relief to see my 3 kg shipment heading to the USA. I felt a bit taken advantage of, but they did ship me what they said they would.

I also feel like mainstream reviewers are scared of bitmain. When you tell the story of a product, tell it all. This was a serious example of a major fuckup in business.

The saving grace, and this has been their saving grace many times, is they do eventually deliver running systems. Even if you do not like bitmain for many other reasons, the majority of the hardware runs.

Maybe that is the approach of the mainstream reviewer. They do not want to say anything negative about a company, especially bitmain. So, they keep the review strictly hardware related.

In that sense I have to give bitmain great marks on the S7 for some simple things.

They sent a  quick start / rma guide, and while there were a few typos which are unfortunately common with that many words in a doc coming from certain parts of the world, it is a big step for newer and older miners alike. More so for newer.

They have a safety label on the machine, which in turn also makes it look more pro.
Most of us probably have safety information memorized and realized, but it never hurts to have that reminder in your face. I believe this is a big improvement.

The Aluminum chassis is awesome. I am worried about damage to the corner of the hash boards for those of us who enjoy different configurations and prodding. (once out of warranty of course)
They are closer to having a modular miner imo.

The used market will be a mess with speeds ranging from everything which has been posted in this thread.


What do you think is the best and worst about the S7?

Best: I like being able to adjust the fan speed. I turned it down so it's no louder than the S5 now and working fine.  The biggest is the electric savings over the S5.

Worst: the ROI

And as I am getting ready to crash for the night I ask again.

Has anyone received an active shipping notice for batch 2 and or 3?

A notice that ups or fedex or dhl shows as the unit or units in motion?

Nothing so far for me, B3 order date:

2015-09-29 17:24:30

yeah  as of this morning the 21st no one has said they have confirmed tracking for Batch 2 or 3.

the clock starts ticking on the 25th of oct when it comes to these batches. My guess is they will not ship any earlier then the 23rd.

Back to batch 1 does anyone have a batch date on the 20th of sept or 21st of sept?  If you do have you got any 'real' shipping info?

I do believe they were up to the  Sept 19th dates on batch 1

three batch 3 coming tomorrow ups
coming with 3 batch one, hope I can tell the difference.

so you are the first to report a batch two or batch three shipped

And anyone know why a transformer can only handle half the load at 240v???

Define 'half the load".

Wattage rating for power flowing through a transformer is the same regardless of voltage.
Now the voltage or current ratings - THAT is what changes. Watts = Volts x Amps. When providing the same wattage, double the voltage and the current side is cut by 1/2 or conversely cut voltage by 1/2 and available current doubles.,

Not sure, there were multiples starting oct 3 I think. Ordered and paid.
Was selling s5's to get cash for s7's. Bought all batch two starting october after buying batch ones beginning of sept, they are sending three batch 3 instead of three batch 2 so far.

A friend of mine is just getting started in bitcoin mining... thanks to me, I got him hooked ;-)

He raised a question that I have no answer to... The question is:::

When would bitmain receive the funds if he wired money?

He's asking because he wired funds yesterday, Oct 20 for a couple S7 batch 3's and his order still says UNPAID as of 8am CST Oct 21

Are you saying that you purchased Batch 2 miners and Bitmain is shipping you Batch 3 miners instead? How do you know they're Batch 3 miners?

That doesn't make sense. Why would they skip shipping batch 2 miners & send batch 3 miners instead? I ordered batch 2 miners & never got an email - has anyone else?  Can you post the email for us?

Who emailed you this?  You seem to be claiming a lot of firsts.  First to report shipment, and now to claim batch 3 instead of 2.

That almost sounds to good to be true on giving batch 2 batch 3 quality for same price.

So happy so far with my Batch-1 s7 so I ordered a B2 one today. Wonder how long this one will take?  
Also - why are the batch3's a tad more expensive than the batch-2's?

Batch 3 is 4.86 TH/s @ 600 MHz and Batch 2 is 4.66 TH/s @ 575 MHz.  200 GH/s difference and 1160 watts for Batch 2 verses 1210 watts for Batch 1 and 3.  They are both still 0.25 watts per GH

Interesting. My batch-1 s7 came with factory setting of 600mHz and is humming along perfectly at over 4.86 as reported by my pool. Guess I'll just have to goose the coming batch-2 one to the same and see how it does.

I believe the batch 2 are batch 1 rejects.  They were not mining to specifications they laid out for Batch 1.  However, they should work fine at 575 MHz instead of the 600 MHz originally quoted for Batch 1.

I agree with you dmwardjr, although Batch 1 left me with 5 of them running at 575 at 4.6th/s.  I did get a couple that maintain 600 at 4.8th/s.

Nice share from my S7.

Lucky you, Bitmain seems to skipping earlier placed orders in favor of larger orders placed early October. No shipping or UPS notification for my order placed on the 29th, the day B3 went on sale
