Bitcoin Forum

Has anybody heard of or purchased from this website. They constantly have advertising banners here, just wanting to know if its safe to purchase from them?

Yes lots of good comments...  Though they do seem pretty busy, if anything goes wrong fixing could take some time.

https://bitcointalk.org/index.php?topic=417159.0

I just received my order from them this week that shipped super fast.  I'll keep buying from them until someone else decides to actually compete.

Bitmain is pretty great.  Their produces are delivered on time or faster (± normal noise that happens with international shipping), and their products are exactly as specified. Their products are industrial workhorses. They do not come in a sleek plastic case with useless decorative lights, instead— they actually work.

I don't get the impression that they have a bunch of fluent English speakers around, so communication is sometimes a bit spotty. Some people who've had packages get stuck in customs or received the odd defective part have reported it taking a while to get it resolved.

Like all current mining hardware companies their prices are so/so in that you're making a gamble on future difficulty, though they've been diligently lowering the prices as the expected future income goes away.  But the fact that they deliver on-time and to-spec— what really should be table stakes— makes them stand out in the business of Bitcoin mining.

Bitmain sent me a 90GH/s prototype unit before they started shipping, with the current firmware antiminers are awesome on P2Pool. Subsequently, I purchased a couple more on my own as a regular customer. 

I've recommended the antminer S1 to friends, and if you're thinking about getting into mining for fun and to support the network, I'd still recommend them. (Actually looking to turn a profit at it— well, thats a more complex question)

So i 've  had fun with the u1's I bought from a us supplier how much more complex are the s1's.  If I order the miner does it need a seperate power source I think I read this somewhere, and does the power source have to be custom built? Thanks for the replies guys!

You can use an ordinary computer PSU, with some care in selection for one that provides enough power on the pcie power connectors. Beyond that, they're basically self contained— a little embedded mips computer running linux and an ethernet port.

What about too much power?

I've found a guide on coin miner.ch  gonna. DL this and read it

That's subjective.  If you're concerned with efficiency just underclock them.

Ordered One 3/15 @night for 1.11BTC - Got a confirmation email this morning that it has shipped.
I'm pretty certain that you have to provide your own power supply (lots of support on this forum on which to buy and how to set up)

I'm happy so far...will be happy to update you.

Bitmaintech.com great manufacturer
i ran S1 in my home

Bitmaintech.com is the official site of the Bitmain Technologies Limited, which is the vendor producing the ANTMINER Bitcoin mining rig. Thanks for your interest.

I got 5 antminers from bitmaintech with delivery expected tomorrow from what tracking says. Vary good service answered my email questions within 24 hrs and the process from order to at my door in under 7 days !!! You also won't find a better price. I wouldn't be suprised if they sale out fast ...

They are also good for giving out discount coupons to existing customers, I got 5 ants for 4.72 BTC today :D

I mean the psu having too much power frying the circuits? Is it possible?

3$ and some cents a gig hash that's on par with some preorder miners isn't it?

The new 28nm hardware with the A1 chip is running at half the power consumption of the ant. But you can get the ant now for less so personally I will run them for a bit until the A1 stuff comes down in price. Piece out the old farm and build the new.

No. Think of it the other way around. The devices pulls only as much power as it needs from the power supply. The power supply does not force power into the device.

Agreed... why hope for tomorrow when you can mine today?  :D

Ahhhh k  makes sense thanks

Bitmain rocks. I have 20 pcs in hand. They have communication issues , though.

So  a 450 w PSU with two pcie connectors should be sufficient , considering bitmain's 360 watts a the wall statement, and do I need to understand the 3 +12 v DC input  statement  or will the two pcie's sort all this out?

I'm terrified to buy the s1, I was reading the set up and trouble shoot and now I'm worried I won't be able to set it up....

Its not that bad to setup, if your really worried about it and order  your unit from minersource you can purchase a config to go with it and just plug it in when you get it and it will start hashing.

Sorry for my lack of knowledge with Bitmain, but about how long does it take from the time to order to receive it at your door? And are there faster shipping options?

Thanks

Just ordered 6 Antminers from Bitmain and 3 850watt power supply from Tigerdirect.  Do the Antminers need the wifi antenna for the wireless function or does it work fine without it?

Shipping depends, to the USA it takes about 2 business days in transit + the time from when you place the order to it leaving the factory (could be same day to 1 or 2) and also depends on where you are located. I'd say about 3 days but it would be different if your located elsewhere.

Its one set shipping method, using a different carrier might speed up shipping if you are near one of the hubs.

It's really easy now.  Early models required some custom wiring for the power, but no longer - the power connectors are just standard PCI-e connectors.  Your Power Supply (which you need to buy separately) will come with plenty of PCI-e power cables, the S1 needs two of them.

The setup of the S1 is really easy, I had about 15min. I used https://bitcointalk.org/index.php?topic=355387.0 (https://bitcointalk.org/index.php?topic=355387.0).
The shipment from Bitmain took 4 days to Europe.

Very easy setup, I have purchased 4 units recently and just plug them into your network and most by default are set to 192.168.1.99 that I got and if not use a network scanning tool to find them and mine show up as Paragon Technolgies Inc. or Shenzen SHX Technologies Inc. as the vendor so they will be easy to find on your network if they are not that IP I mention.

For Windows you can user Angry IP Scanner or for OSX use Lan Scan Pro and you will be able to find them rather easily.

After you find them login with username/password which mine were all root for user and root for pass and then go into miner configuration and set your pools and worker names and your good to go, to overclock user Google and you will find the info.

Good luck!

Ok mabye not so scary  :)  I guess the scariest part is telling my wife I'm buying one........

450 watts is cutting it close if you're going to overclock... which you will want to since it's so easy.  Why not buy a 1000+ watt PSU?  You're going to want a second S1 anyways.  ;)
But seriously, don't skimp on the PSU and buy cheap.  You'll likely regret it.

I'm not sure about overclocking  my u1's get lots of hardware errors and rejects but will get 500w  or more PSU  maybe will get the 1000w ?

Is it possible to mine alt coins with the new U2?

Any sha 256 coin

So it can't mine scrypt. Well that sucks ass. Oh well.
Still better then my current setup.

Has anyone had issues getting S1 through customs and having to pay import tax or duty?

Remember, don't invest what you can't afford to lose because *anything* could go wrong, you may indeed reach ROI but you may not depending on when you actually buy, the pool you use etc etc....no guarantees at all and if BTC goes down to half the price it is this morning well you can already imagine what that means.

Personally I don't trust the mining profit calculators and don't find them accurate compared to my actual real world results but again do NOT spend what you can't afford to lose as things are getting late in the game and soon 200 GH/s will be worthless. I have four of the Antminer S1 and can't see them being very profitable after another 60-90 days and their will come a point where power costs more and it will be better for me to sell them all and hope someone with a larger farm that doesn't pay power will want them. I may be wrong and perhaps they will last a bit longer but nobody really can be 100% accurate and if we get flooded with 2 TH/s miners soon that will affect things.

Don't forget the cost of power! I have a power monitoring system and can tell down to the cent what each watt cost and overclocked my Antminer S1's for two of them in my home are using 864 watts and I pay 6.99 kWh this month so I am paying about $1.40 for two units per day and $2.80 for all four of mine per day to run 24/7.

Simple math says all 4 of my units will cost me $84 in power this month but what if next month my power goes to 12.35 kWh which alot of times does happen, well then I pay double the cost for power. I am currently making about $60-80 per day on average from what I can tell however difficulty is increasing and this will get less and less so I don't need to say it again because I already warned you twice about your investment. :-)

I cannot post a image and get an error "invalid proxy" when using imgur otherwise I would show a capture of my power usage for two Antminer S1, I'm sure others get the same numbers as I do in regards to power usage etc.

Good luck!

Geez don't be such a bummer dude. If I couldn't afford one I wouldn't buy it  ;) besides I see it as a hobby so instead of a thousand dollar remote control boat this is what I choose. Cash rules credit ruins.....

Yep, I had to pay 273 € of import duties and VAT to belgian customs for 2 units, shipped direct from China.

I second this.

I ordered on Monday and they are already enroute via UPS to NY

Tell her she gets the first BTC ;)

Man, you are too serious about this :)

For me, BTC is pretty undervalued right now (limited 22M supply; still widespread mainstream skepticism, even more after Gox; less than 400K wallets with > 1BTC as of Jan/Feb etc etc). Actual daily volume of BTC is also pretty low since most people who hold bitcoins are pretty stubborn holders, so the low daily liquidity is not reflecting the true value. So in all my ROI calculations, I assume a much higher floor than the current $600-ish value, but that's 3-5 years out and I'm really patient (have yet to even sell my Amazon stock from 1999).

But you may have a different time horizon.

My Ant S1 came today, also delivered was a bookcase that I'd ordered from Overstock: One of them was a pain in the ass to set up.
Thanks in large part to this forum...it wasn't the Antminer ;-) < that went smoothly. If you are a (slightly above) basic user of computers and can follow directions you'll be fine  :)

There were no duty or other fees for me (I'm in the U.S.) Shipping was included in the Bitmain price

Does bitmain also charge you for shipping? I didnt want to place an order just to find out

+1 for bitmaintech!! ;)

I ordered my S1 from bitmaintech on March 6.  It shipped on March 8.  Arrived at my door in the US on March 12 (that included a one day weather delay by UPS). 

As already stated, +1 for bitmaintech!!!

Nope.  Shipping is included in the purchase price.

shipping is included as well as support and return shipping within the 90 day warranty period if something fails.

Awesome thank you. I had 1 more question. I know what kind of power supply i would need (i actually had a cx650 on hand) but the wording on bitmaintech sounds like it comes with a power supply

I thought the same thing

Here's the wording "Power effective: Saving the investment of PSU, cable and the cost of electricity bills."

Is anyone selling these directly in the UK, i'm sure i went to a site 2 days ago who were but can't seem to find it any longer

No they dont come with power supplies i recomend this one for running 2 antminers not over clocked!!

Dont buy a cheaper one I have a cheaper 850 watt power supply and it kicks out twice the amount of heat !!!

I just bought an S1!!!!!!! And I don't care what my wife says ;D.  I'm stoked can't wait to get home from working in the frozen north to set them up. Should get back just in time, the wife will be over her shock and should be able to set it up with out the feeling of piercing eyes  thinking about strangling.....

I'm running 10 off 5x CX750M, no issues.
Swapping them all out to have 3 on 1200W HP Server PSU's though... Can't beat it for $20/1200W

Oh no my order expired even though the bit coin went through  :o . Fuck I hope my wife doesn't get the last laugh  :'( .
Anybody have an thoughts on this?

What do you mean by "expired"?   Bitmain is very reliable.  Be patient. My last order didn't show it was "shipping" on their website until 2 days after it shipped. Good luck!

Its never easy to watch your money in limbo , the order expires after an hour if they haven't received payment, even though I sent the bitcoin immediately it expired and show unpaid, was a long night thinking about my wife telling me  " I told you so" , but this morning it says paid. So everything good I guess they will manually send the order is what I  got from a prompt message return here in the forum from bit main.

How do you set these up? Saw the interface boards over at gekko science but IDK how to config the board, load balancing, and all that.

Yeah same thing happened to me with the expiring, and was sorted out with tracking - minus the wife telling me I told you so :)

I've bought a few S1's from them, always professional and prompt, so I wasn't worried at all.

The S2 model is on sale now on bitmaintech.

Yeah exactly. I always had faith, read so many good things. Cheers to Bitmain!!!

My S1 is on my porch according to UPS.  I'm at work though. :(

Got home.  Plugged it in.  Powered it up.  Configured it.  Mining. :D  (Dinner.)

Will let it run over night and then do some overclocking tomorrow.  I have to go back to work in an hour though so the fun will have to wait.

pictures?

Of me or the S1?  The S1 looks just like any other.  And if I showed you a picture of me you'd just be jealous. :D

Haha lol   :D

I bet we'll see many S1s' for less than 200$ in the next month on ebay.

Was there any cable cutting or needing to use a paper clip to trick the PSU into working? I have one route today!!!!

No cable cutting assuming you've got two 6 pin PCIe connectors.  You will need a paperclip or something to jumper the pins on the ATX plug to turn the PSU on, but that's standard ATX - they all need it.  It's been running rock solid as expected overnight at 180GH/s and 47 degrees.  Mine has the latest firmware, and was preset for 192.168.1.99, (not .2.99).  Conceivably you could just plug it in, hook it to your network, put in your pool info and be hashing.  I'll be looking at overclocking it today.

correct it is now configured to 192.168.1.99


you can just hook it up,  turn it on,  set up the pool info and away it goes!   time from opening UPS package till mining about 3 minutes :)

Hellz ya

But it is a good idea to change it to 192.168.1.100 or anything else , so that you will not mess it up with your next S1!  ;D

I suggest you also to buy a server psu (ex. IBM x3650, DELTA DPS835.etc) for MUCH less, which is also much more reliable than any silly pc psu.

Each will cost as low as 10$ and can supply TWO overclocked S1s'.

Just my 2 cents.

I was considering that, but idk how to wire it up to an interface board....

Thats the magic.... They will sell for at least double that on ebay in late April.  

what do you mean?

http://www.gekkoscience.com/products/D750_supply_breakout_board.html

The psu costs 10$ and the breakout poard 70$ ???? ???


many lessons here:

http://www.rcgroups.com/forums/showthread.php?t=1766215

You need a soldering unit and little practice.

Dont spend your money.

Jesus Christ those pictures scare me, looks like an awful lot of fucking wires. Lol good luck to anyone who tries its probably simpler than it looks but I'm just gonna buy a PC PSU.

The thing is that they are server psu's, meaning they are designed for 24/7 operation at near-full load, some even rated for over 125% spec. All at 90% efficiency. Plus theyre cheap. Yeah but for the reason you stated, im going with a tier 1 or several tier 2 psu's for my antminer ambitions xD

well, for those wondering whether it is safe or not, i purchased my antminer on a saturday... sent an email and received no response (no email from purchase nor when its shipped nothing), however, monday was shipped, and by wednesday/thursday was at my house.

it's been working for the past 2hr~ at steady 178GH/s (no overclock) w a 750corsaircm... all good, recommended...

  Purchased from whom? Bitmain? They are kinda slow with responding to e-mail but pretty good at getting merchandise out the door. But I am curios in case you got that from someone else.

bitmain, i bought it directly from them-

cant connect to s1 at  http://192.168.1.99  Trying to connect from my laptop; Ethernet cable is pluged into bell 2wire gateway. when I type in ip says page cant be displayed

Is your laptop and router on the same network as the Ant?

From your laptop, do an ipconfig, and confirm it's also a 192.168.1.x address first.

Its not the same how do I change it and should the Ethernet cable be plugged in the router or my laptop

First take note of what your Laptop IP is and what your Router IP is(Gateway usually ending in .1) by doing an Ipconfig on the laptop.

Connect an ethernet cable directly from your laptop to the Antminer.  On your laptop, change your laptop Network Adapter setting(not wifi adapter) from automatic to manual or static IP address on same network as Antminer.  This is usual in Network and Sharing, Network connections, Local Area Connection, Properties, IPv4.   Make it like 192.168.1.123 or something, Subnet mask 255.255.255.0, and Gateway 192.168.1.1 then hit OK and OK again.

Give it a few seconds to connect to the Antminer network, then go to a browser and go to 192.168.1.99.  Log into the Antminer then go to Network, Interfaces, WAN, Edit.  Change the IP to a free IP on the same network your laptop and router is on, make sure the gateway is the same IP as your router IP, leave mask alone, then make custom DNS 8.8.8.8
Click Save and Apply, give it a minute or so, then unplug ethernet cable, set your Laptop back to Automatic IP.

Once your laptop back on the same network as router, open browser then go to Antminer new IP and login, configure Miner configuration with pool address and worker info, and you should be on your way.

Good luck,

Chuck

Laptop can be wireless, that's fine.  So can the Ant, but for stability purposes let's keep the Antminer on Ethernet.

Were you able to connect to the Ant and configure?

no

says this page cant be displayed

send me your bitcoin address. I'll send some your way for your troubles.

zero hash rate??? saw a green led on right side of board after a reboot  (right side if your looking at fan directly) but gone again after shutting down miner and turning it on again. miner status says pool alive some getwork some discarded, antminer stats nothing.... anybody ?

Hey Angus,

Post a screenshot of your miner configuration and wan interface configuration so we can help you here.

Chuck

Yo angus!

Try to ping 192.168.1.99 WHILE you are connected to the same internet network as the  s1. This will(hopefully) tell you whether your s1 is on that ip or not.

You can also try resetting the s1 to the default ip (there should be a sticker above the stock fan...). To reset, there is a small black button below the ethernet board. press that for around 45 secs while it's running.

or... you can download a ip scanner to scan ips in your network. trial and errot test.

Hope this helps!

how do post the screen shot ?

 I don't think its the config pool says its alive but no hashrate and the green light on the side of miner is not lit up.

my wan set up 192.168.2.35 ipv4
                255.255.255.0 netmask
                 192.168.2.1 default gateway
                   192.168.2.255 ipv4 broadcast
                      8.8.8.8 custom dns server

miner config  stratum+tcp://pool.webcoin.us:3388
                    AngusCanine.Jason
                     1234
             

Looks like your router is set to 192.168.2.x

Do you have access to your router? You have to change the router to 192.168.1.x in order to access to the antminer.

I have access to s1  those values are the s1's new address and my mining pool, funny enough ive switched pcie's and the green led on out side of miner on the board came back on. but still not hashing pools alive, zero hash rate

NTP problem? maybe...

define ntp im not familiar with it?

Hey Angus, try taking out the stratum+tcp://

Just enter pool.webcoin.us:3388 then hit Apply and Save.

stratum+tcp:// is irrelevant to the problem. I think it's his internet's problem. My assumption is that the ant lost internet connection -> causes the green light to blink.

I have stratum+tcp:// on my 3 pool addresses and my lovely little ant works fine!

Looks like pool settings/issue or something if he has getworks.  I think Angus should try a bigger pool just to test.

Try BTCGuild or Eligius to see if it makes any difference.

NTP is the time syncronisation. If you go to system -> system. You will see the time syncronisation box. Try disable it.

Pool could be a problem.

works either way

I tried slushes pool , I reset the miner and tried letting it mine the antpools from bitmain its all thesame

Try BTCGuild or Eligius.

wifes hijacking computer for an hour but wil try one of those after

Have you disabled the NTP?

disabled now what to do?

ok I figured out how to take a screen shot but cant figure out how to post it I copy the img from pictures then select insert img but no option to paste its like I didn't copy it

After taking screenshot with your laptop, upload to imgur.com, then post image link here surrounded by the insert img link.

I ordered an Antminer S1 this past Saturday (3/29) and today (3/31) my status shows as "shipped." UPS tracking shows that it should be here Wednesday from China. That's pretty fast!

posted those configs here https://bitcointalk.org/index.php?topic=344970.msg6011060#msg6011060

Is it normal that orders is marked as expired an hour after payment?  ???

What's going on with U2 purchases? I am trying to place an order for them, and they aren't letting me buy.

Yes, blockchain.info is the API for Bitmain, it is slow in reporting to Bitmain's payment site and often product ships before the site ever updates the status.

Don't fear to much, just e-mail them.  Issues with their automatic update I do believe, I have boughten from bitmain twice, both times items shipped in two days after payment and I recieved in 3 days and 2 days after shipping.  Last week I bought monday, had them friday at noon :D.  I <3 bitmain.

After reading trough this thread, i`m no longer worried.  :D And also, i belive the good people at bitmain is sleeping atm.
