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 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 webmaster@bitmaintech.com 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.

"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 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.

I use teamviewer on my local subnet and never had a security issue in two years.
If you hook your miner straight to the internet you will get hacked.
I would notice my Linux machines getting hacked pretty fast, it would overload my internet connection when they started using it to push a crapload of data and Comcast would just block the ip.
TeamViewer all the way for me.

I've heard of people having their wallets stolen while having Teamviewer available on their machine, not sure I'd trust using it with my equipment ( or at least not with the default configuration - short username/password).

Like I mentioned a few pages ago in this thread, a home VPN is so easy to set up with a Raspberry Pi, and most modern routers even offer the feature to enable a home VPN. Much safer than just port forwarding and relying on your username/password being secure to avoid hacking, at least with key-based VPN authentication. Plus, if you have multiple miners to monitor you just navigate to their IP addresses, rather than trying to set up different ports so you can access each miner over the internet.

Most of use really don't NEED to access our home network while out of the house. Some guys are just so geeked out they have to have access to  their home network and files, really for no reason but just to have the access. The best solution is to not have any of your systems facing the public internet. Block ALL your devices/systems. Hackers can get through a simple print server if they wanted to. Having Teamviewer running all the time and other remote software is just silly.  "But then I can't support my friends or help my grandmother out". Then teach them how to run Teamviewer or whatever program when needed and then teach them how to turn it off. I have been hacked many years ago and have decided to just remove the possibility of it ever happening. Port scanners, sniffers, tracers are all out there. Just have to be careful.

BTW this forum software was "supposed" to be updated years ago. The forum operator which I think is sitting on a few hundred thousand worth of BTC never upgraded the forum software so you'll see back to back posts from users "like me" who respond to what they read and then have to go back to the thread to read on. There were threads out there on how much BTC the forum operator was hoarding. Users just keep donating I guess but don't pressure the operator to update to a modern browser. I mean seriously, SMF 1.1?

EDIT: A good read.  You'll read a lot of good stuff in there about updating this forum, which never took place. Why users lied outright puzzles me, but I think it was just to get more donations.

Here's another. Looks like the forum has over 2 million USD worth of BTC. Of course we don't know the real transparency and that post was from two years ago. Slap on another few hundred thousand for donations. Just very interesting stuff. What's real funny is the topic number.

https://bitcointalk.org/index.php?topic=155000.0


Just want everyone to be aware. Throwing lots of money into BTC which in my opinion its value is tied to a dozen or so people. Unfortunately BTC got its good start in the drug market. Do some Googling and you'll have some good reading.

You realize you can check the progress they're making on the new forum right?  I'd also like to know when you think the last donation was received.  It appears you are very confused.  This forum makes BTC from advertising and very little from donations.  

EDIT: There's an entire section dedicated to it in the Meta section.

I was looking for a status update but could not find it. I found the posts from several years ago easily though which indicated the forum had over 5000 BTC in donations so I was only basing that donations kept going. I really did think development on an updated forum ceased since it has been a few years from the original offer and we are still using the same stuff.

EDIT: I did find it. Was in the META area.

My order status for batch 7-sold out is now "valid" and I got e-mail also, so resale was not a program error or something.

I got also mail that China customs demands values at invoice USD even when sale and price is in BTC. This is going to give me some hard times when I have to pay Customs fees and proof what I have paid for the mainers.

I just put in a 20amp breaker in the breaker box, ran a 12-2 wire (all 120v) about 2 feet and I have a nice 20amp plug in the garage.  1600w power supply, (evga), warranty 10 years.  I wouldnt trust the bitmain psu, but hey the main reason i dont buy those server psu is the noise level.  I dont see what can go wrong with the setup.  even if the miner "burns", its on concrete floor, about 3-4 feet away from walls, ceiling is 8ft.  Home mining will never be over as long as we get -30 celcius in winter.  if you live where you need to cool your miners...well thats a different story.  For example in summer it does get very hot, so when it does I just shut it off.  Free heat.  Some btc.  Re-sell miner when the new ones come out, buy a new one.  ain't going to be rich but at least I wont be cold.

Does anyone else think that Bitmain may have oversold these S7 units. By oversold I mean selling so many units that the diff will go up by stupid amounts, killing their ability to sell more batches of S7s pretty soon. At least at the current price that is. I'll admit that I contributed to this problem by jumping in at batch 1 and again at batch 3. For some stupid reason I thought that the diff would stay under 5% per jump as my ROI calculation.

Between the S7 and Avalon 6 (not to mention Bitfury's new miners in its 100 million dollar mine that's now coming online) I think the market might be dead soon. I see that batch 8 has been up for a while and I have a feeling that it may not even sell out if we get the kind of jumps that have happened in the last day or two again when the next few batches actually ship out. Avalon 6s are just starting to come online this week. Most sold on the secondary market are just arriving or in transit to customers right now.

i still calc roi using : current diff + 50% current diff

market won't be dead yet . . . still many have high hopes. miners will be sold out when btc moves. 1 of the main issue is that s7 are still pre-orders, bmt might be doing some r&d + testing while the btc are being sent to them.

s7 is a pretty neat miner besides the 9+1 pcie's .... just my 2 cents

i'm gonna post this again, to those who have "merged" 2 in 1 s7 using single controller, withouth changing any settings, have you noticed that the hashrate is lower than 1 single controller ?

Is decreased, but not significantly.
I use only the very best miners in pairs.

Some of them are working at a frequency 625 (from batch 3)
2d17h       GH/S(avg)   10,063.61
1d21h       GH/S(avg)   10,107.83

Speed is more dependent on the ambient temperature and the PSU. 


Waiting for the current six miners.

thx for the answer !!!

i've already received my batch 5 ... u haven't ? i was really surprised they shipped out early.

did you upgrade your FW to latest ?

just DL the tar.gz file then flash direct ? have to unpack ?

[RichBC]

Very interesting and not what I had expected. They have got rid of the bottom 9 chips in the chain, as opposed to 9 out of the middle I had predicted. What I do not understand is what and why that additional component (Large Inductor?) and the additional capacitors are for? Unless perhaps there is a buck converter chip on the other side of the board & we have moved away from the string design? Need a Sidehack opinion here?   Or perhaps it's a hybrid with a buck converter to a slightly lower, Adjustable?   voltage & then still a string for the chips?

Also a picture of the other side of the board would be great?
