Personal text my ass....
I dont understand why they are changing it so much ? Are they keeping the good chips for them selves and then just selling off all the poorly binned chips to us ?

Why not just have made it a 4TH machine from the start and not have it so highly strung. Users can OC just like before.

I doubt that very seriously.  It's possible [after assembly] they keep rigs that meet certain parameters.  If I owned BITMAIN, I would keep rigs that met certain parameters as well.  Wouldn't you?  Does this mean all the rest are trash?  No...

I prefer the batches with more strings that results in better power efficiency rather than the 4.0 TH rig with fewer strings and less power efficiency.  I know it says batch 6 is the same .25 watts per GH/s.  However, I have to see it to believe it.

Just wait until the after-market on these. You can't just say "S7 for sale". You'll need to indicate batch, GH, chips, board version, power consumption, and whatever other specs all these different ones have. A warranty and fix nightmare too when communicating with Bitmain.

Personal text my ass....
"For sure my wife would not let me keep the S7 with that annoying loud howling sound so I had to come up with a solution."

Unless you go watercooled the S7 is not a good idea for home miners, imo. Seriously, what are you guys thinking with your homemade tubes and extensions, they are a serious fire hazard. Let alone the noise pollution.

The extreme heat these monsters are releasing have marked a red line for me. The chance something is burning or melting, as demonstrated with pictures in other threads, is warning sign enough that home mining has reached a limit. And 1200 watt PSUs, do they even last for more than a year 24/7? They are also damn expensive.

Designwise, I don't like the entire single heatsinks on the back of the S7- many have reported them to be falling off. Back in the days of gpu mining you were better off with an AMD 5870 than 5970 too. It was just too much of a hassle to get them cooled and running smoothly. The 5970s often died prematurely, no wonder.

Until something has improved, the S5s are probably as high as I will go until the (final) end of home mining in August 2016.

I'm probably in the same boat. I find it hard to realize people are running these in a home. The noise alone would prohibit to run S7's in an apartment/condo at least in my state (NJ). I'd have my neighbors banging on the door at 10pm. Even after replacing my jet blasters (original S5 fans) with quieter fans I still hear that hummmmmmm throughout my house, regardless of which room I'm in. I do live in ranch style house, which is not a good scenario since internal walls do not have insulation. I did insulate with noise dampening insulation on the cheap. All my S5's are in one room with a single window air conditioner. Even when it is almost 50 degrees out (at night) and 60 degrees (in day) the S5 temps will increase to over 60-62, which I don't like to do. I do admit, if the jet blasters were installed I wouldn't need worry at all. I have to give congrats to the new guys who are running these S7's in their homes. I would imagine some really creative options with trying to suppress the noise. Eventually when temps go down to 40F and below consistently I won't need to bother with the temps at all until the spring, by which time home mining for me will be over. Kind of perfect timing really. I did always want to get some 4-5 inch air duct hose and expel all the heat right out the window, but could never figure out how to build it. Don't want to invest another $1 into that setup, so all choices of changing stuff around is not in the cards.

Good luck.






At almost 1300 watts I think I'm done chasing the mining train. I may have mentioned it before, but most home outlets let you pull about 1200-1300 watts for the entire room (circuit). That means you're asking your ancient home wiring to pull 100% for 24/7 mining. Fires are a real possibility once you get in this range. Imagine all the 17 yr old kids that have a few BTC, order a S7, and plug it into their mom's basement unknowingly overloading the circuit like a Christmas tree with too many lights. Spark, spark, and two huge fans to kick the flame up. Now you're looking at a home burning down and possible lawsuits, though with BM being in China a successful suit is unlikely.

I'd never run something like these S7's in my home UNLESS proper wiring gauge and sufficient volts/amps. If you have a family and children at home I would be thinking about their safety before heating up electric lines in the walls and heating up that junction box. 1000+ watt heaters running 24/7 should take special consideration. Just be safe and good luck!!

I made S7 orders and order list says : Paid Unshipped Expired . I made payment 10 minutes after I got order details, is this normal?

The other paid batch 8 order is : Paid Unshipped Valid and There is edit button in it.

Where are you seeing an order list? I ordered one Batch 7 as well when the orders re-opened the other day, and would like to check to see if my order reflects the same status. I received an email from the [email protected] website stating Order Paid, so would like to think that I'm fine.

Just waiting on a reply from Finksy regarding the Server PSU breakout boards and would hate to purchase everything only to have my order canceled due to an error with Bitmains system.....

I have registered account and there is my orders page.

"Expired" order is from batch 7, batch shipping is over 2 weeks ahead, I was sure the order was legit.

ANTMINER S7 BATCH 7 - Sold Out - are FOR SALE!!!!  

gone again

Seems like a few Batch 3 are available for 5.08 BTC. Someone must not have paid for their order.

https://www.bitmaintech.com/productDetail.htm?pid=000201509290954354994vrQh8di06E6

thats weird.  but just looking at the price, wouldnt a batch 8 be better ?

Maybe Batch 3 is on hand and ready to ship because they were available for the orders that weren't shipped? Batch 7 and 8 won't arrive for about 1 month or more. So a Batch 3 arriving by the end of next week should be a better.

Guys you won't get a batch 3 order if you place your order now through that link.. Bitmain told me about this glitch and said look at the web URL and its date, and the shipping dates.  It's an error on their part as they forgot to take down the page.


Thx. It will be interesting to see how they deal with this as i placed an order (and paid for it) for a Batch 3 last night.

That has been happening since the old site, they will either cancel the order outright or convert it to a later batch... Good luck to you

i was wondering the same about batch 7 because when ordering it was named: "Batch 7-sold out"

I went through the order process for the B7 for many units.....It was confirmed by Bitmain with the "Batch 7-sold out."  Should be no problem with the B7s

I try to pay for my order with USD and I get this error : Can not buy different currency once

How can I pay with USD wire ?

Contact their support (you need an account for this)
https://passport.bitmain.com/login?service=https%3A%2F%2Fsupport.bitmain.com%2F%3Futm_source%3Dforum

Else you can mail them directly:
https://www.bitmaintech.com/about.htm

Most probaly they have to fix a bug and will allow you to place a manual order.

Are you buying PSU on the same cart as well? If yes, that might be an issue, try placing orders separately.

Easy setup as i am used to. Just adding a pool and voila, my miners are hashing away.

I saw that some are using this PSU EVGA SuperNOVA 1300 G2 1300W for their S7. How's it working out?
I'm using a G2 1300W as well to power my S7. It's been running for a few weeks now with no major issues. However the one problem I've been having with my setup is that whenever I have a power failure, the PSU won't boot up again automatically when power comes back online. If I want to start up my miner again, I have to pull out the paper clip jumper and pop it back in again. So that's something to keep in mind if you live somewhere like me where power failures aren't uncommon. Other than that I'm really pleased with the G2 1300W.

I saw that some are using this PSU EVGA SuperNOVA 1300 G2 1300W for their S7. How's it working out?

fantastic-no probs so far, but you need two PCIe extenders that you connect to singles and then balance the load.
I do it it the following way:
first row: Position 1 and 2-two connectors from double headed red cable, Position 3-one connector from a "single" that was split with an extender cable
second row: Position 1 and 2-two connectors from double headed red cable and Position 3-second connector from an extender
third row: Pos1-single red cable, Pos2-single red cable, Pos3-first connector of the second extender connected to a single red cable
Controller-second connector of the second extender

I bought extenders from either Startech (they are 50% more expensive, but connect very snugly) or Jacobs parts-those do the job, but sometimes take a few seconds to fit them. Both are 18 awg, which is enough for the task.
Startech-$6/cable
Jacobs parts-$3.95/cable on amazon -search for "PCIE split cables"

 I never have luck getting an order through Bitmain before a batch sells out so I spend more and purchase some of my gear off Amazon. Recently I pre-ordered two Batch 5 S7 from a seller named BitVet who assured me he had plenty units secured from Bitmain. Well as of yesterday he cancelled both of my pre-orders and will not respond to my messages. Just wanted to give a heads up so nobody else here has their time wasted by this dishonest seller. Looks like other buyers had the same thing happen to them as well.
