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

What exactly do I put in there?

When I look at my old shipping labels on recent packages I received, I do not see my company's EIN number on them.  I would still put "HST CODE: 8471.41.0150" next to your SSN or EIN number.  However, It is more important to put "HST CODE: 8471.41.0150" next to your street address.  I believe you also are allowed to give a special note to the carrier when you place your order with bitmaintech.com.  I recommend also putting "HST CODE: 8471.41.0150" in the special note to the carrier when you place your order with bitmaintech.com.

EDIT:  You see my address covered up in purple.  I put "HST CODE: 8471.41.0150" out to the right of my street address and out to the right of my EIN/SSN number as well.

EDIT #2:  When looking at the address label on each package sent to me from bitmain; it does not have my EIN (Employer Identification Number) or SSN (Social Security Number).  Which means by putting the HST CODE out to the right of the EIN/SSN number will not be on the address label.  However, there may be some other piece of paper accompanying the shipment with that info.

After you have chosen a carrier [I chose UPS as an example] here is where I was talking about adding a note for delivery with the same HST CODE I mentioned above  "HST CODE: 8471.41.0150":  You can even go as far as to be more detailed in that NOTE to the carrier for delivery by stating the following:

8471.41.0150

Which is:

8471
Automatic data processing machines and units thereof; magnetic or optical readers, machines for transcribing data onto data media in coded form and machines for processing such data, not elsewhere specified or included.

41
Comprising in the same housing at least a central processing unit and an input and output unit, whether or not combined.

Already ordered some batch9 can I still change it?

Already ordered some batch9 can I still change it?

I would think you can if it's not marked "shipped" yet.

However, I'm not sure if you can make a special note now.  You may have to go to the order and click it to see if you can.  If you cannot, I would at least make the addition to your address with that HST CODE included next to your street address and in place of your EIN/SSN number.

EDIT:  Probably not a bad idea to go ahead and call UPS and tell them you need to add an HST CODE to a shipment coming in from China and they will transfer you to the proper department to take care of it.  I'm telling you this because of this episode I went through:  https://bitcointalk.org/index.php?topic=1165628.msg13432585#msg13432585  I have to wait 6 to 8 months before I find out if I have to fork out almost $900 because of a mistake an agent for UPS made by applying the wrong HST CODE to my shipment that resulted in charging me a 2.6% tariff.

Now there is always someone who opposes you, you will never do this,
I'm fighting just to eliminate these mistakes, and I also opened a poll, but here people are afraid that bitmain not send more miners to end users,.
these people are the classic form of chickens, but by man have nothing, and the world goes to pieces for these people.
cmq you did a great job to specify these things, let's see if people wake up and pull out the balls.

With an s7, rule of thumb is :  overclock if you want, underclock if you want, find a good setting with sub 0.01% error, and then - DONT TOUCH IT EVER AGAIN.    Also check out the luck we had at Kano.is pool

Only thing is if bitmain catches you doing overclock it will void warranty.  Current batch 8 I have not seen a overclock to make it worth losing warranty for.

Chances are they will not catch you.  But it is possible they might depending on problem you have. (Which hopefully there will be no problems and not need warranty)

It seems they won't warranty the product anyway.

I lost another b8 hashboard today. It was underclocked at 675.
Guess I shouldn't have moved it above 650.  Still no word on the 2 batch 5 boards I sent to Bitmain.
Will be 4 weeks on Monday.  This batch 8 board had been running 3 weeks.  Lost another batch 8 board running stock 700 about 10 days into mining.
Emailed Bitmain about it and again - no response.

It should be good for 3 month's.  I have luckily not dealt with RMA since S3 day's.   Honestly on batch 8 you should leave it at 700.  If you mention over/underclock that ruins warranty.  You have to get permission to do pretty much anything now.

I would email/send ticket/possibly contact US support if you are getting no where.  But they should respond to email.  How many units did you buy and how many had issues?

I posted info about how many purchased and how many had issues a couple posts down.

As for Underclocking the batch 3 - I'd rather have some boards functioning than leaving them at 700 and having them fail - especially if support is not going to live up to warranty replacement.
I don't see how underclocking would do any thing to void warranty - if anything it should rather extend it.

I have sent 4 emails via support page and a couple to info@bitmaintech.com directly.  No response for 4+ weeks.
I've tried calling the Denver support line today, got voice mail.  Been trying to call the 3-phone numbers in the AUTO Response email that emails result in.
All say - Sorry, the mobile phone you are trying to reach is currently turned off.  Should be about 2pm in Shenzhen right now.

BITMAIN,

WHAT IS UP WITH THE LACK OF PROPER SERVICE OF LEGITIMATE CLAIMS?  

WILL YOU PLEASE RESPOND TO ALL LEGITIMATE CLAIMS IN AN EFFICIENT AND TIMELY MANNER.  IT WOULD BE APPRECIATED GREATLY!

KIND REGARDS,

DAVID

Thanks for chiming in David.
I would love to be PRO Bitmain, and have been in the past given my past experiences.
I bought around 30 s5's early last year and had one fail - controller and boards.  I sent them in and had replacements 2 weeks later.
I did send an inquiry email after they had it for a week, and they responded and asked for patience but that it would be soon.
Too me that was acceptable.  These past 3 weeks however have been discouraging.  Without any feedback at all - not so good.

I did finally get through to one of the Mobile phone numbers for support and spoke to a pleasant sounding lady.
I was disconnected 3 times, and kept calling back and getting her again.  I'm not sure if it was bad connections or what. In the few minutes we were connected it was hard to make out everything she was saying.
Her English was quite broken and connection wasn't the best.  I think I'll have my fiance call in as she speaks fluent Mandarin, but don't really want to bother her as she's busy teaching at Penn State.
I did kind of make out that they could not access the bitmaintech support tickets online, so that might be part of the problem.  I told her I also emailed direct to info@bitmaintech.com too.
She told me to email again and they'd respond by tomorrow.  I hope so.

Thanks for the update.

I'm about to spend a lot of money on power upgrades.  I'm not following through with it if I can't trust my supplier.  I just sent another email to info@bitmaintech.com.  I've always been kind and respectful in my emails and taking up for them in the forums.  I cannot continue to do so if this continues. 

Maybe someone will send the replacement blades I'm suppose to receive soon.  I say this because I'm beginning to have second thoughts about upgrading my power now.  If they were in my situation, they would feel the same way.  Wouldn't you?

I most certainly would feel the same way.  In fact I was going to purchase 4 more s7 units and offload my remaining s5 units, but that's not going to happen unless I know the products are being supported.
Ramping up power service and purchasing loads of miners.  I'd want 100% certainty support would be there in case of failure.

On a positive note - I did just receive an update from sherry

hi
Sorry to keep you waiting
Something wrong with our ticket .
We  have received the parcel and i'll push our shipping team to arrange the shipment asap
Infirm you the tracking number once ready

I just received an email from them as well.  They forwarded the email to Sherry and are asking her to check the status on the package that UPS says was delivered on January 4, 2016 and signed by MS GAO.

It looks like they are getting on top of it now.

Thanks for the re-assurance.  I was getting rather worried about all the plans I've made with the engineer from the power company, county inspectors office, boring contractor to bore underneath the road across the street to the transformer pad and electrical contractor.

EDIT:  I will delete my previous post in red ink above.

I'm seeing a lot of problems on batch antminer S7 8
believe me I'm about to throw up

[marvykkio]

I trust in a company more serious, and that sells good quality products, yet there is this company, but I think that within one year, perhaps two, someone gets in the game,.
the material they use to build S7 and too low, this is the truth.

Today I deliver the first 3 x S7, we see how long they last



there was someone who told me that I am a hypocrite,
because I'm complaining, but I buy from bitmain,
surely this person is a moron who does not know where he lives, and speaks only because he has the mouth.

However, I confirm.

poor customer service.
poor material
poor customer support RMA
