Topic: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH - page 90. (Read 527798 times)

If you haven't already, send an email to [email protected] (the email address on the flier), write order number on the subject line. Did you order a B8 or B9, except for B1 later batches were shipped on time and even earlier, so I don't know why it took 20 days for you to receive your miner. My personal experience, Bitmain has replaced my B1 boards twice already (2 boards the first time and a fan, and 1 board second time). I like the S7s better than other available miners on the market, cheaper and more hash.

Thanks hawkfish007, I did try that address, but I will try again. I didn't try their skypes, I will also try their skype's when they are open Monday / time zone.

I have not tried this yet either.

Ugh, you are totally missing the point.  -- I am looking for first hand experience, someone who has worked with bitmain, more than just a single unit. Just asking questions.  If you have experience with these units, ordering, and live in NA, maybe PM me or something. I can ask you directly. Otherwise, just stop being a dick. I obviously have read this thread extensively, so you linking me to the root page is like me sending you a link for something you already know, like this:

Thanks, bingo. That is what I am trying to ascertain. At the end of the day the difference is 100,000 Gh/s.. Which, really in the big picture isn't a lot. Especially if you order 100 units, and only 89 or so of them work.  Then you get no support, or are waiting for a while and they are offline.. I would rather have 100 units that are working with support from Avalon, then a big 'maybe' from Bitmain...


Just wrestling with what to do.. Thanks though. I'll keep reading....

I know that this isn't the right place, but what do you think about the drop in bitcoin overnight?, Do people think it has to do with the Mike Hearn post & leaving in a loud way?

LoL it's all right here ...let me help you ...just read it https://bitcointalksearch.org/topic/antminer-s7-is-available-at-bitmaintechcom-with-486ths-025jgh-1165628

All I know is what I have experienced so far. I have an single S7, my first item from Bitmain. It took a very long time to acquire, 8 weeks. After 20 days,  it has a dead board (board 2) I have reached out since Jan 9, and everything I have sent to them has been ignored. I have had no reply at all. With the BTC price being so low right now, it makes me want to pounce on the S7's but I am worried that A) I will never hear from them again and B) support will be an issue.

Makes me want to just cut the hashrates, and go with the safe bet of Avalon units.

With that said though, I do like the interface, the setup was easy, and the PSU was really nice too.. So.. There are pro's and con's for sure. Mostly, if there was a support channel I could trust, this would all be moot.

But I see what you are saying, some people are saying that they are getting great service.. It's just hard to do business with China I guess. Especially in a volume like this. It's a big risk.

A lot of people come in here, completely clueless and ask help for a startup and its typically a waste of time. Eventually it is found out that the user in question is way over his head and it gets more pointless and pointless each time, because the same questions are asked and the same answers are given over and over. And it always end with the user in question not having realized that its not feasible in the first place. Which means there are about 100 startup thread with all the information you want.

Imo Bitmain is a pain to deal with, if you are in the US, i recommend the Avalon 6 instead. If you want to deal with RMA with a Chinese company, then sure. But you won't be covered for anything that breaks after about 85 days after you received the miners.

However the S7 is cheap and not as bad as people try to make it look like.

https://bitcointalksearch.org/topic/m.13530166 and there are plenty more.

I am doing research. That is what this is.

Show me a thread where someone says Supoort is good, tells you how long it took their units to arrive. Explains customs and shipping cost.

Don't be a dick. It's a rule on this forum.

Just wondering if you are new to BTC mining, since you are ready to order 100+ units but never ordered from Bitmain.

Shipping by UPS is usually $55/S7 anywhere in US. Once shipped it takes about 2-3 days for delivery. I have probably ordered over 60 miners starting from S3 but some people here ordered hundreds. Their may be a one time brokerage fee from UPS if it is your first overseas purchase and there is no custom's or tariff on miners.

I find it hard to believe someone that is willing to drop $100K does not do simple research into what he is buying. All the answers you want are either here in this thread or on Bitmains website.

Thank you for your note. More questions for you.


Did you order units from them ?

How much was shipping ?

Are you in the USA or North America? Was shipping difficult ie. Brokerage or customs etc?

How many units did you order from them ? I find it really hard to believe they arrived in two weeks. But if that's true. That is amazing

My compensation was for delayed B1 shipping which was scheduled to be shipped between September 21-30, but Bitmain was more than 10 days late. Bitmain sent an email for BTC address verification to me on Dec 28 for this.

same here.. and bitmain seems to not care about my request for compensation..  i wonder how the others are getting theirs

They are the best units on the market.  From order to delivery is usually about 1-2wks unless specified on the site says something else.  They do stand by their products for 90days, but put you through all of the troubleshooting yourself if something goes wrong with a unit.  They email pics and procedures on how to test and evaluate the problem unit.  If you cannot resolve the issue, they have you mail the hashboards or control board back to them without the metal housing.  You have to pay the shipping.  The turnaround from problem to getting the repaired parts back to you is about 3-4weeks.  Hope this helps.

I asked this question a few pages back.. I am thinking about ordering between 90 - 140 units from Bitmain S7 the batch 9, but I am asking. Has anyone ordered from their site before? How long do they take to arrive, how is their support?

Does anyone know? Or are most people here just buying one or two second hand from EBay?

Phil it's been a while since batch 1 but I thought I also remember once Bitmain knew they had a problem with under preforming miners they started asking people if they wanted the miner with a small refund to make up for the lower hash or wait for a miner that will mine at the advertised rate? It seemed to me there was a few days that people ended up with lower preforming miners before it was caught. Without digging thru all the old post that is the best I can remember, but I just assumed those first slow ones would get also compensated like they did for the others that were asked if they wanted them or wait.  I really didn't follow much about the S7 dog miners because I was not effected by it.

let me check and see how I paid them

here is first order

My batch two is a really good machine so I do not complain
One of my batch ones was good so I do not complain.

but one of my batch ones they owe me coins.

I asked them 10 times for a few coupons for later orders nothing.

and now they are paying others for the batch one.

I do no want to burn bridges with them but  I need compensation.


I should get .47 btc to this address  1JdC6Xg3ajT3rge3FgPNSYYFpmf53Vbtje




they gave lee's group  hosting 67 usd a miner for low hash batch 1's  I got 67 usd back for that batch one

but the one in my house nothing  I have posted on this 20 or more times.

 I even purchased 7 or 8 more units asking for some coupons to make up for this.

I still have hash at their hashnest .  So to give comp would have been simple and easy.



I sold this batch one unit for a discount price to buysolar.

  I dropped my price 150usd  so my loss was 150usd and 2 months of under hash  so even at that number it is about a 0.4 btc loss.

Phil our comp was for being late not for under hash. Not sure what to tell you on that.

how did you get it? 

My batch 1's were short hash  like 4500- 4600  vs the 4860 I paid for.
