The voltage doesn't matter...
There are usually 15 and 20 amp circuits... 15a = 1800w 20a = 2400w
This machine will probably trip a 20a circuit... If I end up getting one I will have to use one plug from two circuits
Voltage matters (higher efficiency and more stable power). Its not just about the amps. I recently had my house updated to 300A total due to a recent fire caused by all my mining gears (overloaded the main meter) and I had six 20A breakers installed just for mining. The SP30's come with two server PSU's, so you can split them between two circuits, but the voltage has a big impact. You can check the SP10 threads, no one on 110v get's anywhere near 1.4TH/s. I believe the highest I remember reading about was 1.3TH/s, and that was with someone blasting the a/c right in the intake fans to keep everything very cool and stabilize the voltage so some doesn't get lost as heat, and with a lot of fiddling around with the settings. EDIT: Also, you should never max out your circuit breakers. Treat a 20A breaker as a 18A breaker. It's best to leave at least 10% headroom. So it would be more like 18A * 110v = 1980w per circuit. The SP30's have two 1200w PSU's, presumably pulling 1300w each (they advertise 2500w total, I highly doubt that). So as long as you split between two different circuits, the amperage won't be an issue, but the voltage still will be. In hindsight, I wish I had those guys install at least two 220v lines, I regret that -_-' It would've only cost me about $75 more at that time, now I would have to pay about $800 to have everything redone. The first versions of the SP10 firmware limited the PSUs to 1100 watts on 110V power. I own an SP10, May batch slow corner and I get a consistent 1.4TH/s out of it with the 1.5.2 firmware, and the tweak to remove the limiting of the PSU. Believe me, I would love to have gotten one of the earlier ones that got anywhere from 1.5 - 1.6TH/s, but no such luck. As for the SP30, if I do end up purchasing one, it's going to be hosted. I've got a full breaker box, so if I wanted to get more power, I'd have to get the entire thing redone, and up my service from 200A to 300A, and then put in a few extra 240V/30A circuits and the Nema outlets. Way more than I'm willing to invest for my mining gear. Maybe in the future I'll consider it, but for now... EDIT: By the way, bitmadrid, it's the 15th. What's the final price you've negotiated? |

Whoa.. how the hell did I get four of these... Perhaps an error cause I am a B1 S3 customer... I chose the refund soo I'm gonna way a day or two to see what happens.
LOL... nice error  . I'm B1 S3 customer as well and chose the refund option, too. My S3s are on the way and should be here by Thursday. No extra coupons for me. I've got a couple that expired on May 30th, though... hehehe. |

I have a second minute batch 1 order and I havenīt received tracking yet, so I doubt they have shipped in quantity yet.
However, it does take some time to update all the tracking info, so I might be wrong.
Go to ups.com. Go to "TRACK BY REFERENCE". Put your order number in the reference field. Put in your zip/postal code and country. If your package has shipped, you'll see something like this: Shenzhen, China 07/15/2014 10:52 P.M. Departure Scan
07/15/2014 9:45 P.M. Origin Scan
07/15/2014 8:32 P.M. Pickup Scan
China 07/15/2014 10:19 A.M. Order Processed: Ready for UPS Mine are en route and scheduled for Thursday delivery. |

In my opinion, even if they correct it 504 will not be achievable due to ASIC chip limitation.
As of now max we can achieve is 441Ghs.
If we take the risk and we are lucky enough to overclock to 478Ghs, take it as a bonus.
Efficiency wise, as per Bitmain's statement, we are still at 0.77J/W that's a good thing.
Do we even know why the limitation is present? I was of the understanding it had to do with the DC/DC regulation, not the ASICs themselves. Although, perhaps you're right and the Eng. Sample ASICS were higher quality than those of the first production lot. Could be either or both. From Bitmain's description, it is the DC/DC component that was the limitation, but I imagine the ASICs could also be something like a slow corner and inherently have less performance than their initial samples, and the DC/DC couldn't be tweaked to compensate without issues. |

Guys, I just copied my ORDER ID from BITMAIN website to UPS -> TRACK BY REFERENCE and it worked!
S3 were shippied earlier today and will arrive to my house at Monday
Package, Freight or Mail Innovations? Did you fill in the destination country and zip code? Order I'd doesn't work it says enter a valid tracking number You have to click on "TRACK BY REFERENCE" Nice! Track by reference worked for me, since I couldn't sign up for UPS My Choice. My shipments are on the way with a scheduled delivery of Thursday. Shenzhen, China 07/15/2014 10:52 P.M. Departure Scan
07/15/2014 9:45 P.M. Origin Scan
07/15/2014 8:32 P.M. Pickup Scan

What do you need for registering in my ups my choice? And where is the tracking number on the order ?
Just go to the UPS website and sign up. It's free. Put in your info and UPS will tell you what packages it knows about that are headed to your address. |
|
|
|
|
You can use 1 coupon per S2 that you purchase. You can also donate your coupons to others.
|
|
|
|
Can you guys elaborate? Did you get a shipping email? Did you see at tracking number on the website?
It appears that people who are signed up for UPS My Choice can see that their packages are en route. Unfortunately, I cannot sign up as my address is listed as a commercial address, so I have to wait until Bitmain updates the website (or I get an email from them) to have any tracking info. My order was placed for batch 1 at 14:01:44 (yes, that's 1 minute and 44 seconds after orders were opened)... so I'm hopeful that I'm one of the folks included in this batch of shipments. |

I guess you are both right, it is a risky business, both, mining and holding, but by mining you also have chance to see how things work in details. With luck you can get maybe a bit more, but nothing to be considered final. I'm sure there must be hardware out there that is having positive ROI, otherwise nobody would be minig these days. Maybe 20k$ as i suggested is not enough for a decent mining rig (as i said, i don't know much about hardware).
It is indeed risky, which is kind of what I was leading to in my earlier post about mining being a finicky business. By mining, you are seeing the process in detail, and also helping to support the Bitcoin network. With $30,000 are you going to make a significant impact on the entire network's hash rate? Not at all. Even if you had 6 of those SP30s in hand right now you would be about 0.03% of the total power of the network. If you look at the expected earnings, if you did indeed have that 36TH in hand right now, you would expect to crack a block every 24 days or so if you were solo mining. Again, I'm making the assumption that you have it in hand right now and difficultly doesn't change. Obviously an incorrect assumption, but for the sake of a simple discussion, it will do . Using a calculator, assuming a 20% difficulty increase and ridiculously low power costs of $.02/kwh, and also assuming you had that same 36TH in hand right now, you could expect a profit of about 24.57 BTC before the costs to run the hardware were more than the coins it produced. Realize, this is speculation, not reality. Maybe the difficulty increases are greater than 20%... maybe electricity costs go up... etc. For example, if I push the start date of that 36TH/s out 60 days (so mid-september), and keep everything else constant, you're negative ROI. The biggest problem is actually laid out in my last sentence in the last paragraph "...keeping everything else constant..." because this whole crypto-currency thing is anything but constant. This is what makes it so much fun . Totally agree with you and one more interesting thing here: when miners will start cutting off power for their miners, there will be less BTC available, so the price of it will go up, what will cause more miners to start mining and there goes the cycle. I'd love to see chart of BTC price related to mining ROI compared over last 2 years, so it will be clear for everyone that price of BTC now is very low based on difficulty of mining. Yet another aspect of the whole speculation. Also, don't forget that block rewards diminish as time goes on. The next halving from 25 to 12.5 should occur some time in 2016. There are so many variables... |

I wonder how much each miner has generated so far.
I know the hash rate of each miner and when I installed them, but I do not have statistics of how much each miner has generated. Is there any calculator that shows this based on historical data?
If you use the Bitcoin core client, you can export your transactions to a spreadsheet and figure it out from there. Some pools provide historical stats on how much you've been paid (Eligius, and some p2pool nodes for example). Any calculator you use won't tell you how much you've actually earned, they will only tell you approximately what you *should* have earned. |

older people. Tried to explain to my parents, they just don't get it. Let alone grandparents. It's a waste of time it seems.
But that's not the problem. Even regular joes just don't get it. "Where does the money come from?", "whats the intrinsic value?", and so on and so on.
What's your experience with this?
Just tell them it's magic internet money and it comes from pixie dust and unicorns. In all seriousness, I've had success explaining it in terms of accounting and ledger processing. People seem to understand, at least in general, how credit cards work. In terms of storage and usage of the money, the concept of safety deposit boxes, account passbooks and wallets works well, too. I've also been successful in just explaining it as a foreign currency. If you go to Japan, you convert USD into JPY. BTC is just another currency into which you can convert your dollars. Finally, talk to them about investment vehicles, and stocks. If you can relate BTC to things they know and understand already, they'll get it. |

So I need some help here peoples. I do fly in fly out work with a 3 week on roster. So im going to be away from home when the miners arrive. My girl is home but is absolutely computer illiterate. I have setup the power supply ready for when they arrive with labelling for which cables go where so she can just plug them in. But as far as setting it up goes would i be able to setup the miners remotely with teamviewer with another computer set up at home? Reading about the S1 seems the internet has to be disconnected and then connect the compter directly to the miner. Is this true with the s3 do you think? Does anyone have any ideas how I could set up the miners remotely? Thanks To answer your question would require a bit of knowledge about your home's network. Are you running a 192.168.1.* system, or are you using something else? I am guessing (and this is going on Bitmain's usage of that network in the S1 and S2) that the S3 will follow the same pattern and use that type of address. Assuming that Bitmain continues to use the 192.168.1.* addresses, and your home network is on that same network, then using Teamviewer to setup the miners remotely shouldn't be a big deal at all. My home network uses 192.168.2.* Is that configurable? Could I just change the router to assign the DHCP setting to 192.168.1.*? Absolutely. Changing your network is usually pretty easy to do in your router's config. Thanks for the help. Network has been changed to 192.168.1.* Had to re-cycle all the devices on the network to get them going but were all sweet now  As was posted above... take some screenshots and print them out. Show your girl how to handle making the changes to the router in the off chance that the S3s come with a different address range. This way, you can call her from the road and walk her through the process should it be necessary. My guess is that Bitmain will stick with the 192.168.1.* range. Also, make sure you have statically assigned IPs for your current miners so there isn't a conflict. Do something like 192.168.1.201-210 depending on how may miners you currently have hashing away. |

I've been thinking about getting a small miner just to feel like I am a little bigger part of this movement, and was wondering if anyone would have any advice on what hardware to buy. I don't expect a ROI, though it would be nice, but am looking for something < $500 if possible. Is there any hardware on the market worth buying at that price point? I'd consider both SHA-256 and Scrypt ASICs.
The one's I've given the most thought to are the Antminer S1 now that it's on super sale, and the Zeusminer Blizzard. The antminer seems like a safer bet with all the huge Scrypt asics coming online soon, but I was wondering if anyone had any input and if I had perhaps missed a better hardware deal.
Thanks!
The Antminer S3 would be the best bang for your buck but currently they are only selling them in sets of 2. You could try emailing Bitmain and petition them just to sell you one. There are resellers that will sell in single quantities. As for the original poster's budget, I'm not sure you'll be able to sneak under that $500, however. If you truly are capped at $500, your options are to pick up a few (3 or 4) S1s (try the market here, Amazon, eBay, etc). You might be able to pick up some of the Rockminer rigs as well. If you want scrypt, check out gawminers, zoomhash, minersource, etc to see what they've got on sale. |

I think most of people here are just wrong. They all asume price of Bitcoin will remain at 600$. Cmon we all know that is bullshit and there is a big bump coming really soon. If i were you, i'd invest 20k$ in mining hardware, and 10k$ in BTC, i'm sorry that i can't help you choose hardware, i'm not following that scene to be honest, but i'm really sure price of BTC will rocket till the end of 2014. Trust me, you will be sorry if you didn't buy at 600$.
cech4204a, you have a different notion of ROI than what most miners envision. Buying a miner for 10 BTC of fiat funds and mining 8BTC on it is a net loss - even if the coin goes to $1,000,000 per coin. If you buy the miner for 10BTC and you mine 12BTC that is a +ROI, but very few miners did/do that. Once the growth slows down for a sustained period, ie 3 consecutive jumps, then it will be easier to gauge which hardware might turn a true ROI. Until then it's all just guesswork and hoping other people fail at getting their miners so that you can make a profit. Mining is a zero sum game. My notion of ROI is dependent upon the currency I use to purchase the mining hardware. I wholeheartedly agree with you that spending 10 BTC on a miner to get 8 BTC back is a negative ROI. However, if I spend $3000USD on a miner and that nets me $10000USD from converting BTC to dollars, then I've made positive ROI. Granted, I could have just bought the BTC straight out with my initial investment, but I didn't. Now, do I think that there's a lot of hardware out there that will return more BTC than you could purchase for fiat? Well, my S1s did. My SP10 I purchased with fiat, so the BTC I get from mining with it I convert back to fiat until I recoup the initial cost. Any more that I earn after that is positive ROI for me. Would it have been better to buy and hold? Yup. Had I purchased BTC with my initial investment in the SP10 I would have spent about $510 per BTC. So, I haven't made as much with my SP10 as I would have with a straight purchase - in terms of fiat ROI. |

Turns out it was an IP conflict with my laptop.........., guess I should have thought of that before.
Thanks for the help though.
Does anyone know anything about updating the miners? I want to be able to tweak them for optimum performance, but the only things I've changed so far is the basics to get it mining, and then overclocked them via Putty. Do firmware/software updates exist for these type of products?
Thanks again,
Congrats on finding the resolution. Hope you get to feeling better, too. You can find the latest Bitmain firmware here: https://github.com/AntMiner/AntGen1/tree/master/firmware_S1Also, Kano has created a cgminer binary for the S1. You can find it here: https://github.com/kanoi/cgminer-binaries/tree/master/AntS1Make sure to follow the read me on Kano's github to properly install the new binary. |

So I need some help here peoples. I do fly in fly out work with a 3 week on roster. So im going to be away from home when the miners arrive. My girl is home but is absolutely computer illiterate. I have setup the power supply ready for when they arrive with labelling for which cables go where so she can just plug them in.

Does anyone have any ideas how I could set up the miners remotely? Thanks To answer your question would require a bit of knowledge about your home's network.

My home network uses 192.168.2.* Is that configurable? Could I just change the router to assign the DHCP setting to 192.168.1.*? Absolutely. Changing your network is usually pretty easy to do in your router's config. |

Any news on when Batch 4 will open ?
My hope is that bitmaintech sources new dc2dc components that can properly handle the load and batch 4 is released with the originally promised specs and can be safely overclocked. If not I will likely go the opposite route and under clock them and see if I can get 4 running on a single EVGA 1300. |

Over 1Ph/s!
We've been flirting with the 1PH/s rate over the past week. I've seen it go up to 1.1PH/s, then down to 450TH/s. Right now, I show 743TH/s. What really needs to happen is that the pool rate drops to like 50TH/s... the share difficulty drops to like 250k... I get about 1000 shares... then we shoot up to 2PH/s and solve 10 blocks in a row Haha but the value of each share is adjusted anyway when that happens right? Yeah... The shares are weighted. It would be much better to find above average number of shares at the current difficulty. |
