ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH

[TrevorS]

How much units an Antminer S5 & S3 consume in a minute or an hour with normal , bronze & gold smps?

Please hep me guys.

As I understand, the S5 is on the order of 40 to 50% more efficient than the S3.  The S3 is rated at around 360W at the wall and the S5 around 590W at the wall.  Expect a 2 to 4% greater efficiency with Gold Vs Bronze supply.

I have two Delta fans in a push pull configuration.  SO MUCH QUIETER.

I am running 2 S5s and an SP20 off the same circuit in my garage and it keeps tripping the breaker.
What underclock settings should I use until I can get a dedicated circuit for my mining?

On my SP20 right now I'm at .66v (max .665) and 188W per loop.. Getting steady 1.23 TH/s

On my S5s right now I'm at 312.5M Frequency .. Getting steady 1.15 TH/s

What adjustments can I make to keep that circuit breaker from tripping w/out giving up too much hashing power?

[lex_minutor]

How many Amps is the circuit? If it's 15A it would give you a max of 1800W but you should never run at 100% for a long time, 80% is recommended which on a 15A breaker would be ~1440W.
You should get a power meter (such as the popular Kill-a-watt) and check what each machine is using.
But I would not run 2 S5's and an SP20 on a 15A circuit, even on a 20A it's iffy (on 20A, 80% power is ~1920W).
Those S5's are probably drawing at least 1000W and then the SP20 is probably 700W-800W at the speed you mention, if not higher.

Wow , are you on an old fuse system or 10A?

On a 20Amp fuse I can run 4 SP20's @ 600-700 watts each and 2 S5's at stock speeds with the fuse only getting warm.

Check your wiring.

Check your wiring.

2*650W+2*590W=2480W  2480W/120V=20.7A  Looks like you're at the edge at best.

My 15A breaker supports 1 S3 and 2 S5 or 1540W/120V=12.8A which allows it enough margin to be happy.

I believe it is 20A.. hmm.. could also be the refrigerator on the circuit when the compressor kicks on?

But I would like some clarification:
-For the SP20 what role does Watts play vs Volts (yes I know one is power and one is potential but how does that translate into performance)
-For the S5 what role does Frequency play?

Very doubtful your safely running that on a 20amp circuit.  I'm sure you meant to say circuit breaker.  For the kids at home don't touch any circuit live or dead to see if it's warm.

I want to know exact unit to calculate electric bill. 1 unit = 1000 watts so how much time it will take for antminer s5/s3 to reach 1 unit of electricity with normal smps.

Yes, refrigerators, microwave ovens, stereos, etc, all have an impact on a shared circuit, they all draw current, just as do miners!  If you didn't pick it up from my above calculations, Power = Volts(roughly constant) x Current(depends on load).  For any miner, the higher the clock setting, the more current draw and hence more power consumption.

An example:  My electricity cost is 14.5 cents per KWH (KiloWattHour). To run an S5 at 350MHz for one day costs me approximately (0.145USD)*(590W)*(24hours)/1KWH = 2.0532USD per S5 per day.  I'd probably round it to 2 USD/day.

Check your box to see if you have room to have either an other 110 20 amp or 240 30 amp, have one of them installed for peace mind. on the 240 you can run all three and no breaker should pop.the cost won't be much if you can do it your self  or get friend to, for the 110 it might be 40 bucks for parts, the cost for me to have 2 110 was 60 bucks in parts . my friend wired it free.

Check your state also make sure they don't require the home owner to get a permit,in my state the home owner can do whatever he wants to the existing service with out applying for a permit or needing one . but if you decide to change the service from 200 amp to 300 amps lets say you need a permit and have to let the power company know etc but can still do it your self.

You won't be sorry you added those lines if your breaker box has the room.

but you are diff over loading that breaker as they are telling you, not much else you can do, till, you run that line, other then put two on one breaker, then put one another breaker.

There may be more on that breaker then just those miner as well by the sound of it,  even worse and  unsafe .

Where I live I am not legallt allowed to do wiring and, if caught, it could void my house insurance. Chance to get caught = zero unless I fuck up wiring and investigators discover that as source of a fire. I just pay the electrician and be done with it. I had a 20 AMP 120V put in 1 week ago for $100.

[In words]

A unit's power consumption in KW * hours it runs for (ie 24 for a day) = KWH of electricity used. KWH * price per KWH = price per day.

That is exactly the right approach, it doesn't even come close to risking all to save a few $ upfront. Even if you think you can do it youself, you can't issue yourself the right paperwork and probably aren't legally qualified.

All i was saying was if you can do it your self and know you can, not think you can . why not save that few bucks. but by all means make sure what you do is covered . if you don't know any one that can then pay to have it done but be careful there to , don't trust them either idc how many permits they have or even the insurance.  Make sure even the ones your paying to do it, are doing it right. trust me, i just went thu being charged for some work in my basement and was over charged for work i found out after the fact should have had been inspected by the state they should have got permits to do over and above what they had permits for.

 but DIY if you know how because most of them doing it for a living will over charge you they are out to make a buck off you and any one they can and most will.


I agree keep is safe and legal.

I have actually written up a commodity cost of production model for Bitcoin (You can download it here: http://papers.ssrn.com/sol3/papers.cfm?abstract_id=2580904)  -- But anyway, the idea is if bitcoins are more similar to a produced commodity than a money currency, their marginal cost (say over a day) should equal their marginal product (say over a day).

If the daily cost to run an S5 = 2.0532 $/day and the expected daily production for 1.1 TH/s = 0.011188 BTC/day  based on current difficulty
These two should be theoretically equivalent since marginal cost = marginal product .. so dividing one by the other simply gives you one because dividing anything by itself is one.
However -- since the numerator (cost) units are in $/day and the the denominator (product) units are in BTC/day the "1" is scaled up to accomodate the resulting dimensional space of $/BTC .

So:     (2.0532 $/day) / (0.011188 BTC/day) = $183.52/BTC  <-- this is your breakeven price (given the same difficulty) where below which you should stop mining.

Ok great! But, not everybody mining in the BTC network has a 0.51W efficient S5, the average mining efficiency across all miners seems to be closer to 0.775 J/GH right now - and the expected daily production for 1 GH/s is -- 0.01017 BTC/day. 14.5 cents per kWh is about the worldwide average.. so  taking that into account the cost becomes .145 x .775 x 24 = $2.69 and   $2.69/0.01017BTC = $264.50/BTC which is pretty close to the current market price.

And knowing is half the battle..

Most states in the US can not stop a person from doing their own electric on their own house that they live in. But if a person really is not sure of what they are doing it is best left to someone that does understand it.

If I was an American I would never refer to btc as a commodity nor refer to trading it for cash. Refer to it as currency and when you exchange BTC Currency for US Currency it is not a trade. With civil forfeiture laws you are exposing yourself to confiscation of the assets of yourself, wife, and kids. Don't believe me? Its just happened because a dude did not get licensed to turn his btc into cash and vice-versa. According to the government, you must obtain a Federal trading license to trade with YOURSELF or you get SWATed, jailed, and destroyed financially.

I believe it but how much of that is the truth as to what he or they are  telling us . how much did he or they try to get a way with with out reporting it in the US any income it income and should be reported, that so called 600 dollar rule is not what most think. I 'm seeing a lawyer tomorrow to cover my but i need to fine out more about the law in the US on btc  no disrespect intended > not what some one tells me on the WEBB. I am starting to make more then i ever expected i would , i now have to watch how much i make due i am on SS disabled, my Dr wont let me work that's even worse for me on top of reporting it. but that law i will ask the lawyer about I only know of one state right now that has such a law that is new york. and the FEBs have all ways been that way  they just pop on you , you never know when, how else are they gonna catch the bad guy if he knows when hell run or hide it .I'll bet they were dong more then what meets the eye , that's coming from one who doesn't trust the GOV at all or talking against them. I know that feeling with guns in your face telling you to shut the fuck up , get  held up in the middle of nite same feeling but worse the FEBS have some rules to follow the guy who puts a gun in your face does not care nor due the FEBS . you did say SWAT not FEBS my bad so that's more then likely a state thing so I'm guessing  those three live in NY.

but were OF topic so lets let that it go at that thought your GOV Is same way etc.  just more under control .

The thing i fine funny about that is they just auctioned off a lot of BTC for the BFL ordeal and other illegal actively that goes on with BTC which gives BTC a bad name.

 i wonder if the ones that bought won it  even had such a license.

[Meech]

As I understand, the S5 is on the order of 40 to 50% more efficient than the S3.  The S3 is rated at around 360W at the wall and the S5 around 590W at the wall.  Expect a 2 to 4% greater efficiency with Gold Vs Bronze supply.

Thanks for reply

I want to know exact unit to calculate electric bill. 1 unit = 1000 watts so how much time it will take for antminer s5/s3 to reach 1 unit of electricity with normal smps.

An example:  My electricity cost is 14.5 cents per KWH (KiloWattHour). To run an S5 at 350MHz for one day costs me approximately (0.145USD)*(590W)*(24hours)/1KWH = 2.0532USD per S5 per day.  I'd probably round it to 2 USD/day.

I have actually written up a commodity cost of production model for Bitcoin (You can download it here: http://papers.ssrn.com/sol3/papers.cfm?abstract_id=2580904)  -- But anyway, the idea is if bitcoins are more similar to a produced commodity than a money currency, their marginal cost (say over a day) should equal their marginal product (say over a day).

If the daily cost to run an S5 = 2.0532 $/day and the expected daily production for 1.1 TH/s = 0.011188 BTC/day  based on current difficulty
These two should be theoretically equivalent since marginal cost = marginal product .. so dividing one by the other simply gives you one because dividing anything by itself is one.
However -- since the numerator (cost) units are in $/day and the the denominator (product) units are in BTC/day the "1" is scaled up to accomodate the resulting dimensional space of $/BTC .

So:     (2.0532 $/day) / (0.011188 BTC/day) = $183.52/BTC  <-- this is your breakeven price (given the same difficulty) where below which you should stop mining.

Ok great! But, not everybody mining in the BTC network has a 0.51W efficient S5, the average mining efficiency across all miners seems to be closer to 0.775 J/GH right now - and the expected daily production for 1 GH/s is -- 0.01017 BTC/day. 14.5 cents per kWh is about the worldwide average.. so  taking that into account the cost becomes .145 x .775 x 24 = $2.69 and   $2.69/0.01017BTC = $264.50/BTC which is pretty close to the current market price.

And knowing is half the battle..

If I was an American I would never refer to btc as a commodity nor refer to trading it for cash. Refer to it as currency and when you exchange BTC Currency for US Currency it is not a trade. With civil forfeiture laws you are exposing yourself to confiscation of the assets of yourself, wife, and kids. Don't believe me? Its just happened because a dude did not get licensed to turn his btc into cash and vice-versa. According to the government, you must obtain a Federal trading license to trade with YOURSELF or you get SWATed, jailed, and destroyed financially.

NOTE: You will not get a letter from Uncle Sam saying you must get the license. You will just get a SWAT Team desceding on you exercising a no-knock warrant with guns in your face telling you to shut the fuck up, get your hands behind your head and lay down.

It's not that critical here.  Just like every thing else if your not trading in high volumes the gov. could not care less.  When Btc goes back up or is backed by larger firms is when we need to hide.
