Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order

[AriesIV10]

if i order s9 from bitminer now iget it in 15th July? (Shipping: 5th-15th July)

That sounds logical.  Although, I have found that if the advertisement just came out and you are early on the purchase, the delivery will be closer to the original ship date (5 July).

I have no idea how to quote a comment so please forgive me.  I am also not the best at electrical but I can tell you what I've learned and if someone wants to correct me, that would be great. 

200 amp 120/240 single phase service is probably common for a house, my house is 200 amp 120/208 single phase. 

I started with 1 miner about a month ago, plugged it into a 120v 20amp dedicated circuit and exhausted it through the basement window.

The only reason that I mentioned voltage is because your miners will draw different amps depending on the voltage.  As an example, the Antminer S9 is pulling 1323 watts from the wall.  The calculation is V x A = Watts, so to figure out amps, just divide watts by the voltage.  So, on a 120 volt circuit, it will pull ~11 amps.  That same miner connected to a 240 volt circuit will pull ~5.5 amps.  The miners are also continuously running so per NEC you have to derate the power by .8.  So as an example, a 50 amp circuit x .8 is = 40 amps.  I'm running 6 miners on a 50 amp 240 volt circuit so my miners are drawing 6 x 5.5 = 33 amps which is well below the NEC recommended 40 amps.  My PDU is also rated at 40 amps, so I am well under what that is rated as well.  If I was to plug that same 40 amp PDU into a 30 amp 240 volt circuit I would not run more than 4 S9s on that.  That would draw ~22amps, 80% of 30 = 24amps, so I am safely below the guidelines for that as well.

At this point, I am investing into miners.  I should have invested into bitcoin for the last month, but I didn't .  I have a larger project in mind that I talk about here: https://bitcointalk.org/index.php?topic=1920614.0

Ok So I just ordered 3.... My goal is to have 10 but I figure I should start small. Maybe with 1 on a 120v with the 1800w evga to just test run it

Then I figure I could buy

The "Pimp Daddy" Package - $710
(Add a 50A circuit and go big, with PDU included for clean, simple & safe install)
 - 3x 2880W PSU
 - 3x Breakout boards
 - 1x 40A 4-port PDU with breakers for each circuit
 - 30x 24" PCIe cables
 - 30x 36" Deluxe PCIe cables
 - 3x C19 power cables of choice (see below for stock)
Order components without PSU's for $450

From Finsky so I can power 9 total when I order the 7 more I want and hopefully power that all off the 240v if I can get a 50 amp 240v. Otherwise I will need to run it on a a few 240's? Correct?

[Hockeybum]

I would really want you to verify that you have 240 v and not 208 v at your house before proceeding.  I believe (and Finksy or others can correct me if I am wrong) that the PDU can only handle 12A per switched port and is rated for 40A total power.  The 2880 watt PSU is capable of powering 2 Antminer S9s but only if you have 240 volt power because if you have 208 volts then you are drawing 12.6 A to power 2 Antminers, which may be too much for each port of the PDU.  The "pimp daddy" package will allow you to run 6 Antminer S9s from a 50 amp 240 volt circuit using 3 ports of the PDU, I think in theory you could add a single Antminer to the 4th port, but I wouldn't do it.  Assuming 240 volt power and Antminer S9 13.5 THs I would only run a total of 6 miners on each 50 amp dedicated circuit and a total of 4 on a dedicated 30 amp circuit.  I hope I answered your question.

Sorry yes that is what i meant running 6 s9's not 9 off the pimp daddy setup. I would probably get one more 2880w psu on another circut for the other two S9's and run 1 on a 120 with a 1800w evga psu. Does that sound feasible? I would have to have a 240v installed by an electrician so I would hope they put in what I ask for.

I guess if I want to run a good 20-30 of these down the road I should rent a place for them since 30 would be 150 amps itself and well aren't most houses on 200amp lines?

[Hockeybum]

I think that you would probably not want more than (3) 50 amp 240 volt circuits drawing continuous power at your house.  3 50 amp circuits will allow 18 Antminer S9s drawing a total of 100 amps.  That will allow you 100 amps for other items around your house.  I don't know what your additional loads are at the house but you probably have additional 240 volt circuits for things like air conditioner, dryer, oven, hot tub, etc.  An electrician can do a quick load calculation to let you know if you can draw 100 amps continuously and allow for normal operation of your other appliances and electronic equipment.  30 S9s would be 165 amps, (30 x 5.5), and you wouldn't have enough power at a house to run normally.  If you think you are going to run 30+ I would look to get a space that has at least 400 amp service and 3 phase power.

does this come with the http://www.antbleed.com/ feature still?

A. "Antbleed' was a tempest in a teapot and really a non-issue. However you tagged it correctly - it was supposed to be a (never implemented) feature. for us users to have a back door into remote hosted miners. Understandable intentions, terrible real-world idea on many levels.

That is removed from all current and future shipping miners. Just got a new t9 on Monday, yes the never-activated code is gone.

I would hardly call being able to remotly shut off a device and manipulate the entire mining community a "tempest in a teapot".  How much bitcoin per day do you make running one of these 24/7? at current difficulty and next soonest difficulty.

[NotFuzzyWarm]

This has been discussed to death elsewhere sans tin hats.
What part of NEVER IMPLEMENTED not to mention that the option was user-selectable yes/no/from where have you not paid attention to. Not to mention that is is easily blocked even if it did operate.

link to elsewhere chat?  Did you read the site even?  It seems to me it was non-select-able, built in, and no way to remove it without overwriting that part of the firmware.  Just as a note you do know tin hats are made of metal , right?  Guess what antenna's are made out of?  Better to be a Faraday cager than a tin hatter.

[NotFuzzyWarm]

Yes I read the article and the sh*t ton of babble about it and AB here. It was nothing new.

The early s7's had it as a user selectable feature under the network tab. By default is/was OFF. To turn on I had to both tick the box and enter address and credentials to activate the remote access. When Bitmain decided to drop the idea the code remained OFF and unused. Should they have left the code in there? No. Especially since it was a stand-alone subroutine that did not always interact with other processes. To me it is no different than code in smartphones/tablets to remotely brick them when stolen, just poorly thought out and thankfully never implemented.

Since updated firmware sans the potential back door  is now available for all miners that carried the code - is a moot point.

Tip 'o the visor in Faraday cages. Decades ago my initial work was with long-haul microwave and still do a lot of EMI testing as part of my design work.

[joeyjojoshb]

lets just agree to disagree.  if you read the antbleed.com you could easily test any S9 by putting the etc/hosts file (without changing any settings) to their server to see what it can do.

Anyways, please answer this Q for the miner if you are running it and have gotten some stats on it throughout time at current difficulty, per S9.

so How much bitcoin per day do you make running one of these 24/7? at current difficulty and next soonest difficulty.

[VRobb]

Has nothing to do with "agree to disagree" when joeyjojosmh is wrong...! You'll be hard-pressed to get one up on notfuzzy, and you didnt, and the ignore button is your prize! Nice job, noob...

Now ya gotta know what the answer to that is going to be... For 1, if you are in it for money then miners always run 24x7x365.

Literal income per-day? Anything from zero to good money. Gotta think at least per-month to even out variance and work back from there to get average.

Case in point, I'm running 240THs on Kano and as of late been getting on average 0.0515110BTC per-block we find. The past 2 weeks had some days with us hitting between 2 to 5 blocks per day and a couple blocks that took almost 2 days.

[Sandal_Hat]

Did i see right, antminer s9 is sold out too?

To hopefully wrap up this bit of OT, in this thread the back door hubbub start at pages 209/210. For threads specific to the topic ref my post https://bitcointalk.org/index.php?topic=1493601.msg18762696#msg18762696 for links

guess you never read the antbleed disclosures either.  Try setting your etc/hosts file to the test ip to see if it gets shutoff.  Try taking an S9 that has not had anything done to it from April 2017 and see if it does it.  You would be suprised.

Again, this is not only a dead issue corrected by simply updating the firmware it is also OFF TOPIC for this thread. The offending code is/was in all of their BTC miners from s7 on up and all their Litecoin miners, not just the s9.

If you must insist trolling this dead issue at least have the courtesy to do so in the right thread dealing with it. https://bitcointalk.org/index.php?topic=1888573.msg18761210#msg18761210 IMHO achow101 nailed it. Of course they are just part of the staff here so what do they know right?

[cloh76]

What is the ROI for an S9 on Hashnest?  Is it at most 4 months at current rates?
