Topic: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order - page 136. (Read 531168 times)

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.

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.

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.

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.

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.

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.

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

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.

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?

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.

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?

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://bitcointalksearch.org/topic/delta-vs-wye-3-phase-electrical-service-1920614

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).

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

Oh wow that is really neat cg miner is on it just a little computer managing all the processors. So S9 it is I was semi sold on t9's reliability since I was reading about warranty stuff back and forth. But a new one from them has a warranty while the ebay ones are warrant less and cheaper. I think the warranty is worth buying new. Am I better off waiting since the S9's were last years asics won't there be a new one coming out soon?




If it was a true 240v can't you run 3 s9's off it? I think my house is only capable of 200 amps does that even sound right. There are about 25 15 amp circuit breakers but of course they are not all maxed out or even close for the most part. I am thinking I should start off in my house or maybe running an s9 off a 120v just one to figure it out and configure it and what not and then once I know how to set these up then get a place or put it in a friends place if my house can't power this (sounds stupid I think it easily could) but I also found some workshops for rent with lots of power! I found Finskys thread earlier and I think that is the route I would go over doing the evga psu route many people go.

You have 13 more S9's coming in? Is this you investing money or the previous miners paying for the new miners? (Not to be a personal question but the profit in mining is very different from what it once was when I was big into this (granted people are putting up a decent amount of money on the hardware like I am thinking about doing).

If I was to spend 10 bitcoins on this project I figure 7 coins on S9's which means I can get 15 s9's but I will probably start with a few then get 10 then evolve into 15. Then use the other 3 bitcoins aka $7,500 for shelving wires pdu's power supplies and wiring for the house/rent of place/paying a friend/first months electricity.

The major draw back I have is I am not that tech savey with Electrical stuff. The 240v at how many amps and what I would plug in where is what is confusing a bit too. I understand what a pdu does. So in theory couldn't I plug a pdu into a 240v at 30-40 amps and run 3 or more s9's? I can't figure out how many amps these puppies draw on full load and I really don't want to be flipping breakers. Sorry if I am asking a lot but the one thing I learned in this community over the years is just ask and people are generals more than willing to help. Hmmm I think if I carry through with this I might do a nice picture tutorial/setup of what I did and why.

This is very much appreciated as a long time bitcoin user but an even longer bitcoin lurker on these forums

Make sure that your 240 V is really 240 V; at my house I have 120/208, so I am just running 2 13.5 THS S9 Antminers each on a separate 20 amp 120 v circuit, each with a 1600 watt power supply.  I am also running 6 S9 Antminers on a 50 amp 240 V oven circuit from a 40 amp PDU, I believe the miners are pulling around 5.5 A each.  On a 208 circuit the miners will pull 6.3 A.  The three car garage where I have 6 miners in gets really warm during the day, so you have to really think about ventilation.  Finksy sells power kits for bitcoin miners, I would highly recommend his equipment. There is a thread from him here https://bitcointalksearch.org/topic/ibm-2880w-psubreakout-boards-new-package-deals-for-t9s9-a7-966135.  I did not see on the Bitmain site where T9 is for sale currently, maybe I missed it.  The S9 is sold out and won't be shipping until July 5th.  I have 13 more S9s coming in Friday, just waiting on the electrician to install (2) 3 phase 60 amp circuits at the shop.  If he doesn't do it soon, I may sell these S9s and order more from the July 5th batch.  

If you do read back, you'll see that I'm all about the economics when making choices. I can't see any situation where T9s make sense (and I'm a guy that bought S7LNs [after S9s were released] and turned them into 5.1TH "S7"s). I'm sure you'll find those that are anti-S9 and will say that the added expense of the T9 is "worth it" for the "reliability"; however, if you do the math, every "bad" S9 found on Google, found on Bitmain's forum, and found on some random blog/forum added together likely equals less than 0.1% of units sold.
Given that you have the background, my suggestion would be to get the place (rent, buy, etc.), get it set up for what you think is your max (i.e.,most watts you can pull, most air you can move, etc.), and then, if you envision running 10, buy 10 S9s and let them do their thing. The only real difference between GPU mining and now is that ASICs have cgminer already on them and it's accessed/"controlled" via a browser (in over-simplified terms, an S9 [or the like] is a self contained PC and the ASIC cards themselves are the equivalent of what was, then, the GPU).

I figure I will start off with 3 in my house off a 240v and if it runs smoothly quickly get 7 more or so and rent out a place or find a garage to put them in with the right electrical setup and create some shelves and design some cooling methods to pipe out the air. I think it would be smart for me to run a few and get the hang of it before I buy all 10 maybe I just buy 1 then if I understand it but 9 or 10 more? I was really big into mining back in 2011 with my computer and gpu when that was first a thing but stopped after it was no longer feasible. I have come a long way from losing 100s of coins in a dead hard drive years ago (was like 500$ it was the $5 bubble haha) but there is no reason to be salty about losses and what not. I always was a believer and I now with the coin value so high I figure why not spend 10 coins or so and do what I loved when I first got into it.

Would you have any recommendations for the t9's or any reason I should not buy them? Do I buy new or used? There is so much info out there lately and I feel I can't read it all and asking questions is the quicker and faster approach
