Time to answer some questions!

Quote from: suchmoon on September 11, 2015, 12:30:21 PM

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 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.

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://bitcointalksearch.org/topic/s7-controller-has-nine-18-pin-jacks-so-what-can-we-do-with-it-1173573

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:

Quote from: guitarplinker on September 11, 2015, 09:50:24 AM

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:

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.

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 .

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

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

What's with all the whining?

Even at $.10 per kwh, it profits $275 at current prices. Diff will affect it but so will higher btc price.
Should be able to ROI within a year. Or sell earlier and still be well off.
Same as before.

You haven't taken into account of the difficulty increase. As it increases, the profit decrease.
So it's not possible to break even in a year, unless the difficulty drop.
See the calculation:
https://i.imgur.com/g7xEqnw.png?1

I don't think anybody is claiming that this is guaranteed easy money and Bitmain surely won't price their miners to make it easy for us to make money.

Some people treat it as a hobby, some have really cheap power, some expect the resale value to outweigh difficulty increases, lots of situations here.

Yeah, I take it as a hobby. I know I will never ROI at least while on SoCal Edison Tier 4 rate, there is a slight chance of breaking even after reselling the miner. Still I ordered 3

.

despite knowing that roi is near impossible there is something addicting about mining bitcoin. (and I'm sure Bitmain is very well aware of this)
anyone who claims its a hobby is code for "yeah i started mining bitcoin, caught the bug, now im hooked. roi? ahhh who cares, like i said its just a hobby!

I treat it as a hobby with goal of ROI. I do run ROI and if it's no end in sight I will not buy (exception is lotto mining). But all hobbies cost money.

The difficulty though I think is going to be a little scary. If they keep pumping S7's we can likely see it going up more and more. No more 2 percent changes for a bit.

Difficulty raising right now is a little scary. Looks like a second week with around 5 or so percent. This will kill a lot of ROI's.

I also compare buying BTC to mining when I decide what to do. For example if you hold the 8 or so coins and lets say they go up to 260, you are competing against that too. Holding sometimes wins.

I do love mining and will keep mining though.

Careful with only running 1 fan. I had an AM Prisma that only had 1 fan. The miner was using ~1100 watts and the single fan failed. In a short order, the miner caught fire and was destroyed in a nice flaming bunch of expensive electronics.

Quote from: notlist3d on September 11, 2015, 11:50:25 AM

Watch air closly as you dont want to get to hot. Warranty has changed a lot on what you can do at this point.

Open up a RMA with a ticket and hopefully they send you one for free. If nothing else it documents you had permission to mess with fan.

Did you not read at all

Quote from: guitarplinker on September 11, 2015, 08:23:41 AM

Turns out the second fan was working the whole time, it was just the fan grill that made it look like it wasn't working (derp). So my previous noise level estimates were taken from the unit with both fans working.

Also, I just took a power reading and it looks like this miner takes 1200W exactly for me, using a LEPA 1600W PSU.

Nope. Not at all. Thanks for the helpful comments

How you miners guys making money?
Do you have better luck with pooling with other miners?
or maybe waiting for price of btc to go up in the long run?

I still don't see how running this can be profitable even in a state like Idaho or Washing where electricity only cost 8 cents. Huh

It's not possible to break even in the first year.

I wouldn't be surprised if you are correct. Is that a surprise to you? If so, why?

I don't have any reason to believe that the pricing is set so that YOU can make profit in a year, if ever.
