I opened a ticked on their site and i asked them to send me invoice that is calculated in USD. I hope they will respond early because the expected arrival is on 21.12.2015

Well i'm not sure it matters. At least here, it does not matter what i show them at reception. If the amount is wrong, you need to fill a form and mail it to a sub section that deal specifically with this. And only then if you have enough proof, will they refund the difference.

What country are you in I was looking at past posts?  I was suprised you were going to try to get around import tax it sounded like:

As i said i found people that they helped me to confirm that i need them for personal use and i was explaining that this gear will help my software project to calculate faster the matematical calculations, and also i explained that they stack with another, that means that if one can solve the matematical problem in month, five of them will do the same job in mater of days

Does this mean your country told you pay tax? I was surprised you  were going to even attempt that.  If you would have went to them yesterday it would have caught them on Friday vs weekend.   So maybe honesty sometimes pays off.

Go to your Bitmain account
Under your orders click on option right side for that order.

You are right on S5, price was in USD because Bitmain priced them in USD.
My S5 order shows both, but since they priced S7 in BTC, my batch 8 order only shows BTC price in the "options"

Batch 1 S7 was priced in USD so I guess that is the difference between B1 and B8

Does this mean your country told you pay tax? Or did you decide to not lie to get them?

i was not trying to get around tax, i wanted to pay the tax that they were looking from me, but they did not let me to pay because the price was high for individual person to buy 5 machines you must have company for this mater. After week of explanation i payed the tax and also payed for the documentation and they released my gear. The people helped me just to get in  contact with the right person for releasing the gear.

Just got my first S7 up and didn't realize it was such a noisy beast. I customized the fan to 40% and that helped a lot but now of course I'm running hotter. Went from about 62 to 72 C. It's a batch 8 pushing 4.8 Th and still well below the 80 C upper limit and getting very low HW errors (0.0002%), but I'm wondering if causing damage.

Has anyone reviewed the specs and done a study of temperature vs. efficiency?

Has anyone ever noticed that running hotter was better?

Has anyone running in the 72 C, or higher range, ever noticed a problem due to overheating?

Is there a "best" temperature range?

[Subw]

what is your ambient?

Sounds like the later batches are utter sheyt.

My Batch 1's (That Bitmain still owes me and everyone else $$ for compensation on) ran at 35% fan speed, and 48-51C across all boards.
My friend's Batch 6's run overclocked at 4.45TH at 40% Fan speed @ 54-59C. (And he's heating his house with it. Too funny)

[Subw]

Sometimes I only get one or two boards to start, if I kick the clock down a notch they all pop up without rebooting. Touchy.

That's about B8 also or earlier 600Mhz batches?

It's 32 F outside and the ambient temperature in the basement where I'm mining is 74 F. And, I also bought to help heat the house and it's helping along with some S3s that I've undervoltaged to increase efficiency. Without knowing your ambient temperature can't really make a comparison and whether one is running colder or hotter is not really the issue. I'm pleased so far that it's running so great. Just wondering if anyone has had any problems running in the 72 C or hotter range for a while.

When I had my Batch1's in my basement, the ambient was about 65F, now the ambient is about the same as I have an S5 heating the basement by itself. Outside is in the 40s.

I should clarify, I have extra EVGA G2 Dual PCI-E cable from another G2 PSU that went bad so my available cables are not the same as what's originally ship.  This is what I have now

4 x Single PCI-E
4 x Dual PCI-E ( 2 extra than OEM)

you are fine, then, with 12 connectors available (only 10 needed), just use more of the double headed ones.

It is somewhat ironic that they finished the design on what seems to be the somewhat less stable model (B8) according to first reviews.
It probably should work better at 650.

I have a S7 with a bad Hashboard.  I am sending the bad Hashboard back to Bitmain.  Has anyone run the S7 with only 2 Hashboards?  If so, What did you plug the opening in the place of the missing hashboard to make the air go through the 2 running Hashboards?

I have 2 units running 2 hashboards as the 3rd unit failed in both.
I made sure to run the 2 hashboards spaced left and right and put a strip of duct tape over the middle port on the s7.
Seemed to do the trick with keeping airflow through the other 2 hashboards.  One board does seem to run 2-3 degrees c higher than if all 3 hashboards were in though.. 

Out of all my orders

19 batch 1 - all hashing good (2 units running 4780 ish others around 4850)

20 batch 5 - 2 hashboards failed and have been sent back to Bitmain for replacement. - failure occurred after 2-3 days of use.
                 (all remaining units hashing around 4850)

10 batch 8 - just arrived.  Have only 1 running - 20 minutes now at 4580.  Waiting for more PSU's to arrive for other 9 units.

Hi, I ordered last week and paid for shipping via UPS.
Apparently, they want more money from me now before they deliver it.
Can someone tell me what the fee UPS want now is for?

Here is the message I got from their site:

The driver was unable to collect funds on the first delivery attempt. A second attempt will be made.

Custom and taxes fees

Oh, did you have a shipment where they required that as well?..

I've bought dozens and dozens of miners from Bitmain before. This is the first time UPS asked for money.
Previously, I paid Bitmain for shipping and everything was included. Oh well. Thanks for the info.

What were the values of the other miners?  I believe that customs wants their import fees if the value is more than $1500 or so.  UPS is just a carrier and they have to play by CBP rules.

Sorry Chris, just saw your post.

Previously, I'd actually ordered several thousand dollars worth of miners at a time.

This time, I'm only ordering 1 S7... it was about 1330 + $40 for the UPS shipping, or therabouts (it was in BTC)...
So, for whatever reason, something changed, somewhere. I'm also pretty sure I've ordered 1 or 2 miners from them before, and not had to mess with this extra charge from UPS... Just wondering if anyone here -or perhaps anyone from Bitmain might know something definitive.

Just Duct-taped down the center of the S7 and here are the results:  (Thanks cryptichermit) IT WORKS:
