It may be possible to keep ahead of the ROI curve if you resell the miner for maybe %40-50 of its original price and buy the newest model when it's released.
How often does bitmain release a new s-series? and how much does the resale value drop of the previous generation drop?

There is no stable timeline. Last year they were releasing new miners every 2-3 months. This year the S7 is the first true new miner, so that's 9 months since last release (S5+ doesn't really count). Pricing is also all over the place. Depends mostly on difficulty, exchange rate etc, i.e. the same things that affect your profitability.

Likely they will have competition from other companies before 9 months.  And the other companies likely will have  lower NM, even more efficient miner.

But when?  We don't know.

I don't understand why people say this is not a hobby. I started making PC hashing rigs couple years ago. I had fun building the cases to hold six video cards. Then tweaking all the configs to get the best results. I got up to three rigs running before I started selling off parts. I used money I made from selling off computer parts and the LTC I earned to buy ASIC devices. I used to keep track to see how much profit I made, but got tired of doing that; that is not the fun part of this hobby.

I used the PSU's from the computer rigs to power the ASIC's. At this point I am definitely in the profitable range, but its not like i am getting rich doing this. It is a hobby and I really enjoy it. I have ordered one S7 and looking forward to playing with it too

I think it depends on the scale.  If your largest monthly expense is your electric bill; its not really a hobby any more.

well, then if a better and more efficient miner comes along that offer the best bang for my  buck, I can just sell my older one and use that money to purchase newer model. So I will probably be paying 50-70% purchase price of the newer model .

Time to answer some questions!

Can you try to run it with two PCIe connectors per board? It would be interesting to see if it needs all three.

The miner won't operate with two PCI-e connectors per board, according to Bitmain. See this image: https://i.imgur.com/OV3f8Ql.jpg - Read point #1

Thanks in advance for the sneak peek!

Can you confirm that the controller has 9 18-pin jacks, the same as the S5+? There are a number of us interested in trying to control multiple S7s from a single S7 controller.

I assume that it's the same controller, given the pictures from Bitmain. But it would be nice to have actual confirmation from someone with an S7 in hand.

Also, how long are the controller ribbon cables? Any chance that they would reach to an adjacent S7 next to a center unit?

Note that there's there's already a separate thread around obtaining extra or longer ribbon cables:

https://bitcointalk.org/index.php?topic=1173573.0

Confirming that the controller has 9x 18 pin connectors. See this image: https://i.imgur.com/JzUJsN9.jpg (just zoom into the connector area, the image is pretty high resolutions so you can count all nine)

As for the ribbon cables, they look fairly short. I don't think you'd be able to reach an adjacent S7 with the included cables. But I'm sure some longer ribbon cables would be able to reach the controller from a foot or two away.

How is your power setup for the G1600 on the S7 each blade on its own 12v rail ? (For others reading this the lepa has 6 12v rails which makes this a little tricky set up)

I mentioned my power configuration before:

I'm using the GPU/CPU/RAM rails on the LEPA to power the unit. I have four PCI-e connections on rail 12V5 (three connectors powering hashing boards and one powering the controller) and two connections on each of 12V3,12V4 and 12V6. So in total there are 10 PCI-e connectors on the miner and that's how I split them up.

I took a video of the unit as well, just going to render it and upload it now. Should be up in less than an hour! (Slow internet ftw!)


Some images I took of the miner for those interested:

Thanks for posting this, but i find Bitmain's instructions on imgur's image ^^^ incomprehensible as it is a mishmash of S5+ and S7, especially point #5 where it mixes S5+ and S7 together. Also, why 16A for S7 when it is 1210W, which is 11A even at the lowest 110V. This is a question to Bitmain, of course.

I saw the same mistake (the S5+ instead of S7 mistake) as you, it seems like they through those instructions together very quickly without even proofreading.

They also claim that most residential lines supply only 10A. Here in Canada most residential 120V lines supply 15A. Hopefully they'll fix up these instructions before mass-shipping the units out.

Thanks for the pics! Can't wait for the video.

Looks like I'll have to dedicate 3x power supplies to connect those 9 PCI-E cables. LOL

I know it says that but what happens if connect only two? Does not power up at all? 1/3 of chips on the board don't work?

Thanks for the pictures, looks great.

Video should be available at this link in two minutes or so: https://www.youtube.com/watch?v=5UFGEXyduSA

I realize there isn't a great comparison for how noisy this miner is, but it sounds about the same as your typical vacuum cleaner on high speed.

Be sure to let me know if you have any other questions I can answer, or want any more pictures of the unit.

@suchmoon I can test that out in a minute and get back to you on what happens, but yeah I suspect it just won't power up.

one would sincerely hope so as it is total gibberish right now and would cause quite a few angry or anguished calls/emails if left as is.

Please test all three possible combinations if you can (1+2, 2+3, 1+3) - just in case.

great video, thanks, man
if you want to be a little more detailed, can you measure noise in dB with your Android/iphone from 1ft or 1m distance?
the app is called "dB meter" on iphone
there is also sound meter on android

Yeah, that would be great. Although it's pretty clear that this is not a bedroom miner

my hope is that adding a PCIe split to just two (out of four) of EVGA1300 single red cables will do the trick as you'll end up with 10 connectors (9 for the machine and one for controller)

That is what I did for my S5+.  It works fine.

Sure thing, just tested that out for you.

Phone right up to the miner: 100dB
Phone 1 meter from the miner: 70dB

Thanks for all the work.  Seems like it's pretty loud!  Definitely not a home miner.
