ANTMINER S4+ Discussion and Support Thread

The included PSU cannot be used in countries with a mains power voltage lower than 205V. The PSU will not start below this voltage.

Does this mean a Home in the USA can not use this as its only 110 service?

That's exactly what it means.  Unless you've got your home wired with some double pole breakers that'll give you the 240V, this product is not for you.

Aren't American Dryers 220v?

Good luck convincing the little lady that she's got to hang your clothes out to dry because you're replacing her dryer with some miners .

Electric Stove is also 220... Whats the connectors for 220v to the back of a S4+??? L6-30P to C13 Right?

Yes, so you might soften the blow by telling her she no longer needs to cook anything.

The point is, the double pole breakers you've already got in your panel are already being used for other purposes: stove/range, dryer, central AC, etc.  Virtually every other circuit you've got in your box is a standard 120V single pole.  To use an S4+ at home, you're either going to have to do something silly like replace your appliances with miners or install a dedicated circuit or two (and likely get your total amperage increased to handle the additional load).

How many amps is a 1500w Miner going to pull on a 220/240v Circuit?? my math says like 6.25... thats nothing

 (meaning I can safely run 3 S4+ on a single 20A 220)

At 240V it's 6.25A.  Meaning you can safely run 2 on a 240V/20A circuit.  You only load a breaker to 80% for constant draw.
At 220V it's 6.82A.  Again, you can safely run 2 on that circuit.

Anyway, Bitmain choosing to basically abandon the typical US consumer is an unpleasant reality now.

Because this product doesn't fit your situation doesn't mean they've abandoned you. The S4+ might not be for you and that's okay.

What it does is set a precedent.  Until the S4+ every single product Bitmain released was usable by everyone - from the home hobbyist to the industrial scale farm.  With this, they have completely alienated the entire US home miner market.

To be fair, I had no intention of buying a revamp of last-gen tech, so this product was not for me to begin with.  I'm hopeful that Bitmain will introduce an S7 or similar that will still cater to those of us who continue to mine at home.  However, I also understand the economics of it and realize that unless there's a dramatic shift in the Bitcoin ecosystem, home mining is effectively dead.

during good months of home mining 5k to 7k power earned me 3 thousand a month. Not most months 4 or 5 of  the last 35 months.

this past Jan 2015   6k of power and 12th of hash I got 4 coins and spent  600 usd on power a net of 200usd.

I will not expect to earn 1k a month during any month of 2015. 

The most power I can use is 6 or 7k during cold winter months. If I could buy 2 10 th machines that use 3k  watts each I would buy them as far as i know they do not exist .

I am not particulary happy with the fact that Bitmain decided to not build in an LCD screen.
Even more so, I just hate the fact that there is no "buzzer"
Why would they do that, it was convenient and a good thing to have. The buzzer is just important to have.
Does anyone know WHY they decided to not include an LCD and an buzzer in this model?
For the price and especially the power usage they could at least have placed(keeped) the buzzer..why did they remove it, where they did have it in the "normal" S4..?

Few things:
1) Stock moved from static to DHCP so it can't get stuck on random IPs, which was the main purpose of the LCD.
2) Its got a quick setup button for minerlink, which works similar to WPS devices on a router.
3) Almost no overclocking (overheats) and no underclocking (fixed voltage so constant W/GH). Makes reporting GH/s rather pointless.
4) The buzzer annoyed people more than anything. In small farms it was annoying, in large farms it was often difficult to locate.
5) The buzzer often wouldn't disable properly which was exceptionally annoying.
6) Did I mention the buzzer was annoying? Maybe it will reappear in another model though.

[hmkey]

Thanks for the information dogie.
I would personally still prefer the LCD, and, a working, buzzer tho, even if you dont overclock the GH/s rate would be gr8 to see in my opinion.
So u can see if it still runs at the speed in GH/s u want, meaning no hardware failure probably and most likely, and there are difficulty raises in Bitcoin of course. And IP adress just like the max temp is good to see as well, convenient, in my opinion.

U also know the answer on what the MTBF, Main Time Before Failure, on average, in good environment conditions, would be?
(Since the warranty is short, just like on all other miners tho)

I don't know, and don't know how much data we'd need. Perhaps it could be done on other miners, the oldest Bitmain hardware should be about 15 months old by now.

Our first generation Miner S1 produced in October of 2013, are still hashing!
S2 released in April of 2014 are still hashing!

Warranty is 90-days, however, most hardware do last well over 1 year and S1 as an example, 18 months and still hashing!

Ok thanks!
Im glad to hear that!

[marvykkio]

But strange, at least here in Italy and Europe guarantee of any product is at least two years, I do not know why you bitmain of dates only 90 days warranty. This and a mystery

Miner's do not have near this long of warranty.  It's not bitmain who only does this, but 90 day's is pretty standard for asics.

This gives you enough time to set it up, make sure not DOA.  Also time to set up and get it working properly.   So within the 90 day's you have a lot of time to set up and make sure miner works right.    With how miners switch generations there is no way to do a warranty of near two years.

They stop making the parts way before 2 years.  They move on to next machines, possible different generations.   So even if they wanted to there would just not be parts to do it.

*Please read comment below it appears they have some parts for each generation

Do remember that products sold from a non EU seller to an EU buyers don't have the same rights as EU sellers to EU buyers. Although KNCMiner's legal team seemed to conclude they could sell with 90 days with EU to EU.

Bitcoin Miner is a Specialty Item at the moment.  (Fortunately or Unfortunately)

Bitcoin Mining Hardware, the life span can be very short.

At least Bitmain Hardware sold directly from Bitmaintech.com is sold from Hong Kong, SAR, China.  A special district within China.  

You can certainly buy from some resellers in EU.  Some of the person resells Antminer even post comments here time to time for Antminer products and also provide technical assistance.  They may be held on the EU standard but not when you buy direct from the Hong Kong Company.

Direct Sale only covers the original buyer for the 90-day warranty.

Bitmain is strive to make better and long lasting hardware every day, however, bitcoin mining hardware is still a very early stage mathmatical system that is specially build for a small nitch of market by special demand.

Please be patient with us and we will try to remain the best in Warranty when it comes to the industry standard.


P.S:
We do have S1, S2, S3, S3+, S4, S4+, S5 and U1 and U2 parts are held for Special Request from EU customers for the units that were sold from some of the local warranty centers of Bitmain USA to be compliance of the EU Consumer Protection Regulations as well as the regulations in USA.


Hope this helps a bit

Replace with LED Strobe..

You missed out U3, poor U3

I wouldn't be against some aggressive LEDs at all. If someone's walking round the farm looking for the unit which is down it should be pretty obvious, although the tradeoff is that it won't alert you to a downed machine. You'd have to know there is a machine down.

@dogie,

We do not carry any U3 for RMA in USA, EU, SouthEast Asia, and Ukraine centers.
