it would increase the aftermarket value of B1-7.

One positive way of looking at it I suppose.

Always hate it when manufacturers start saving a few cents in this way. I am assuming it's been driven by the Bean Counters rather than a deliberate attempt to stop people plugging up multiple S7 to a single controller?

Or could mean there is an S7+ on the way?

personally, i don't care anymore...it is not the time to spend BTC, but the time to harvest 'em.

I agree just mine and save btc don't spend any btc.

Yeah i'm guessing an s7+ is coming end of january/feb, will probably be a monster at 4000w, and you will need 30 pcie cables Tongue

If watch the number Antpool Active Workers , then the monsters are already mining in antpool.

165 PHs and 188839 Active Workers .

With 140PHs was over 206000 Active Workers.

Interesting re B1 S7.
It suddenly went from 4.79 Th to 3.65 Th for few hours (before I noticed) without any zeroes or temperature extremes.
Soft reboot fixed the problem.
two possibilities: some chips dropped out, but somehow boards did not show it or miner "got tired' and "decided" to take it easy

This is one of the earliest B1 machines ever delivered (on day two of B1 delivery-9/24 or so)-hashing close to 3 months already, so it would be interesting if someone else observed the same.

Happened to me once for a B1 delivered early too. Hashrate dropped to 2/3 for ~6 hours then it got back up to normal without me touching anything. I just saw the dip on the antpool website and the lower average hashrate on my S7 webpage. I thought it was the PSU acting weird.

2/3 is probably 2 boards out of three (should be ~3.19 Th), but 3.65 Th is a weird number.

So as they said on Batch 8 this looks to be the Final Spec and we have exchanged Spec Changes at every batch for Price Reductions at every Batch.

Has anyone got any more info / pictures of the controller board, with reduced number of Fan & Hash connectors that was reported?

Rich

Here it is:

http://prntscr.com/9ej2n9

Hmm what a load of meanies... Sad

They have depopulated the board, removing the additional Fan & Hash Board sockets. There may well be other components removed as well, but cannot tell at the moment.

Rich

WOW, I don't like this at all. This makes things more difficult and leaves little options in the future if things should go wrong. I understand all of the components used for each unit adds up with multiple units and getting rid of components reduces cost but geeeeeeeez.

No idea thanks to bitmain's legendary incompetence.

Does anyone have any info on the life span of Antminer S7 Batch 8 or Batch 9?
Or at least approximately

Lifespan in terms of making money or reliability?

I am asking because this is going to be my first miner ever. I am planning on running it 24/7 in a really cold room.
Noise is not a problem. Electricity is $0.089 kW/h.
In my country the average monthly payment for a job is $220... Cheesy

With my calculations this machine is going to be bringing me around $415 per month and around $330 profit. Break even in 3 months .

Break even will be longer my friend. But "free" heat is always good no ? With the difficulty rise, you will make 400, then, 350, then 300 per month (im pulling numbers out of thin air), etc. But you will make a profit even after halving hopefully, you electricity isnt too bad. Also consider that you will sell the miner after a while. How much will it be worth after the halving ? Hard to say. Judging from experience, it will retain much of its value. Its a lot of money (even though some people here dont hesitate to drop 50k on miners...but then again its all re-invested money). Also dont forget customs and taxes, I had to pay over 300$cad (god damn...).

I have revised my old hardware return vs network difficulty increase chart to shine some light on this.

This document has been shared for anyone to use.

BTC at $150 USD power costs at $0.03 kWh.

BTC at $450 USD power costs at $0.03 kWh.

https://docs.google.com/spreadsheets/d/1ZphwgPk2lySm3sNlHnow6tuwx6YUV0G7qGDtRZ2xFbk/edit?usp=sharing
You will also find other sheets that contain estimated returns that only factor in power costs.
Please note that this does not take into account hardware or other overhead costs.

Well in my experience miners run a very long time, 24/7. Some people have problems, but it seems to be hit or miss. I've run mine (s1 to s5) for more than a year no problems. Macedonia eh? Cool, I've been there once...road trip...nice place, I remember eating at a 5 star restaurant next to a lake, for a couple of bucks...awesome country. The price doesnt go up with difficulty, but right now it is. Buying mining equipment is a bit of a gamble, like buying bitcoin I suppose.

You've probably been to Ohrid. It's where I live.
So do you think the bitcoin will rise in the next couple of months?

Yeah I believe we are going into another massive pump...to be followed by a massive dump

One last question. I just realised the new Batch 9 on the website. How is it any different than the Batch 8?

As Rich said, batch 8 is pretty much the final version of the s7, so batch 9 seems to be the same as batch 8. But thats a "pre-order" for one month...a lot can happen in one month.

Thanks a lot for the answers.

Spec wise it's the same. Price is reduced, delivery is later.
