Well, after I am been thinking whole night about PSU to fire up S7, I have decided to call up and electrician and get a 240V dedicated circuit installed at my home for my S7 Batch 3 and APW3-12-1600-B2 PSU. Any suggestions?
You will be happy you went this route. If you are getting a 30 amp circuit, you can have 5 x S7's on that one circuit. A 30A 240V circuit takes 2 lines/poles of 120V 30A connections. This would mean its using 60A of 120V. 60A at 120V would also allow for 5 x S7's. Why pay loads of cash to change existing electrical layout if you can avoid it? ROI is already hard enough to achieve no? So you mean, I shouldn't change existing electric layout? If no, then what are my options? Contact a Datacenter and request Quarter Rack? What should I ask them in terms of POwer? 1 X 30 Amps 240V Circuit? Can I power on 5 X S7 with 5 IBM PSU's? You got a good answer already:
If you have a 200 AMP Main Service Panel, you are limited to 200 Amps REGARDLESS of whether it's 120 Volt or 240 Volt. A 30 Amp 240 Volt circuit does not take away 60 Amps of 120 Volt. A 30 Amp 240 Volt circuit has taken 30 Amps of 120 Volts [When measured in amps]. The main service panel is limited in "AMPS" not volts! Yes, it's limited in volts in the sense that your main service panel in you home is rated for 120V/240V. Other panels, especially for industrial use, can be rated at much higher voltages.
So, again, your main service panel is limited in amps NOT volts. A 30A/240V circuit does not mean 60 amps worth of 120 Volt circuits have been kept from installing in the main service panel. I will say this: 60 amps worth of 120 Volts has the same power (watts) as 30 Amps of 240 Volts. You could have a 30 amp/120 Volt circuit. However, it would not have as many WATTS (POWER) as a 30 amp/240 Volt circuit. The main service panel is not limited with a measurement in watts. It is limited with a measurement in AMPS. Your amount of watts (power) used in the main service panel will be determined by what voltage or voltages used in the circuits wired to the main service panel.
You need to know how many amps you have in your main (this is the term for main breaker, some have sub panals where more then 1 breaker but the house should all go through the main). You are limited to this amount of amps. It would take a big job to go above what main is. From what you are saying I highly suggest you get a electrician to come help. As I hate to send you to a electrical box. |

IMO, mining is still live, perhaps laptop mining is dead. Because of difficulty and electricity. isn't it?
Laptop mining was never really a thing. Even during CPU/GPU day's running a laptop 24x7 on high intensity was a bad idea. Most built desktops for the mining. But yes GPU/CPU is dead. It brings in very little you would need "free" electricity to not loose money. And even then I don't think you will ROI on a GPU card at this point. |

I really do love this machine. Hit 30 day's again. Set it and forget it... that is a nice concept in mining. |

I think I understand the basics a bit better now. Get a desktop wallet sounds like good advice.
Thanks to all who replied.
Very important is that you read and research very well everything. With Bitcoin there is no much room for a mistake. For example, transactions are irreversible which means if you send your coins to the wrong address, you pretty much have lost them. So before you do anything, make sure that you understand it. It you don't understand, always ask questions and we will help you. Yes, try Multibit wallet or Electrum wallet. These are light wallets, the, don't require that you download the whole blockchain. Make sure you understand the wallet before you send all of your coins to it. And make sure your computer is relatively malware and virus free. You also have great tutorials online on how to use these wallets. Another thing is, when you set everything up, always test the system with a little amount of your wealth. I do this all the time when I do something new even though I have a lot of experience. So send 0.01 BTCs to your wallet and then try to resend them back so you see that you control your wallet and not other way around. Hope I helped! Cheers! Also he really needs to read up on wallets. I'm not sure how much BTC he purchased but if a lot .... please read about cold/hot storage. If you use a everyday computer to surf do other things, and keep a wallet.... not a good idea. I suggest reading about wallet security before ever taking the coins out of coinbase. It might seem like a lot at first but its worth it to be safe with your coins. |

Sidehack's usb stick is pretty sweet and not very expensive.
It is by far the best stickminer on the market. OP sounds like he want's to mine alt coins... there just are not a whole lot of sha altcoins. Bitcoin is pretty much most worthwhile to mine. As far as altcoins LKETC has a usb stick for scrypt but it's pretty small power overall. It would allow a lot more altcoins but I would just mine BTC for fun off a compac if i was choosing what to do. I predict compacs hold value better then the LKETC scrypt usb stick miners. |

No mining could ever be profitable with those rates, now you could mine with a couple set ups but nothing highly profitable. You could get a micro windows pc (80 -100$ depending on style) and a powered hub (15-20$) , a 20w solar panel ( http://www.amazon.com/X-DRAGON-Efficency-Technology-Smartphones-Foldable/dp/B00NGKPX4Y/ref=sr_1_6?ie=UTF8&qid=1445956041&sr=8-6&keywords=20+watt+solar+panel 57$). A battery backup to make it through the night (13$) For a total of 170$ you could have : Full windows pc that uses 5-6w Powered usb hub with a dc 5v usb cable Battery backup 14$ 20w Solar panel Now for 25$ each you can get 9gh/s at 3.1w, you should be able to easily run 3 of these without any power constraints. So this may sound nuts but buying any miner would just be throwing money away and with this set up you have many things you could reuse for other projects and you could stake off the grid making money on POS coins. Unless he's just wanting to throw away money he should stick to like compacs if he is wanting to mess with gear. Anything big just will never work out. Compacs use so little he could play with one for cheap. But on really mining he would have to look into hosting or cloud. As it will be less then 1/5th of his electricity which is crazy but most will beat it by a lot on price. Compacs are still going to require him to get a powered hub and then to run them all on his desktop will probably use 100w min an hour and if he runs them 24/7 for a month that's 38$ a month just on his pc power, I know my method sounds crazy but he is getting a lot of hardware that is fully reusable and can also stake while he adds more miners or just run as many compacs as he wants off an ac adapter connected to the wall while keeping everything else off the grid. I would suggest using a RPI with it, it can be ran at much lower costs. And a powered hub for 1 or 2 is not expensive. He just will not be able to home or hobby mine. He is to high on electricity. His only option left is mining for fun which the compac does for cheap. And he can always reuse the RPI down the road for another project if board. Yeah this is totally an option, I haven't used a pi 2 so he may have enough power to also stake at the same time as well. I have a PI2 sitting there I played with a little. I have a few projects I haven't got to yet. But it should be able to stake and do a lot more. They really did give it a lot more power. Just seems much more snappier. Runing compacs on RPI 1 B, it's not bad just at points when starting to run I max out CPU so slower. The PI2 has no issues. I suspect if you stake it's a pretty good option for it. I was very impressed considering it is like 35 bucks, which would pay off quick at OP's electricity level. |

The prospects for the home miner is not good. Centralization is increasing along with the infrastructure requirement (case & point - SP50). I think we will see a rise in the private funding of mining cooperatives or mining royalty trusts. KNC I believe is no longer selling to the public and I think Bitfury followed the same path. I think the year for home miner will have some, but lower and lower machines for just home on 110/120. A quick question there I know 220/240 is cheaper electricity but would that mean most North American users would need to use converters on 110/120 lines presuming home mining goes the route of building units that cannot transform electrictity voltages both ways? They actually don't need a "converter" it is more equipment then say a plug you put in wall. You need to actually get better guage electrical wire to handle the higher amps. Also need a different circuit breaker that is set up for 220/240 depending on electricity. It's actually not that uncommon in US a lot of dishwashers and a few items use them. But most houses don't put in extra 220/240 in us for items. So you have to get it installed or install it yourself (depends on local ordinances and your knowledge in the area). |

I'll take a delta over pretty much anything else on the market, 8 out of 7 days of the week. There aren't many others I would trust to keep a $2k investment from burning itself down.
Seriously? There are plenty of good fans out there that are reliable and quieter, Noctuas like i said earlier are pretty damn prestigious in the fan world, I haven't heard of anyone having issues with them. Personally with my mining area I don't care about quiet. I just want a fan that pushes a lot of CFM's and keeps it quiet. Deltas do this (some models more then others). If you put it in a living area yes you need to get a different fan. But overall I think deltas are pretty good. It's just some people are not set up to have a miner that is loud. But I don't predict any of the new miners coming out (whenever it is on the 2 or so were waiting on) to be quiet. |

If you want quiet look at Avalon 4.1 for example it comes quiet, no mods needed. I wish you would have asked on the S5 before buying, and also before selling.
The S5 run's hot and loud. That is just how it was made. There are some who modded it. I think most likely is you modding with much quieter fan's can do push/pull even. But you sold it... so would be a shame to buy another S5.
There are rumors of a new S7 that no one knows much about... so if you wait it is possible it's smaller but no one knows for sure. But chances are it will still be loud, even changing fan's out voids warranty though.
Great information! Can you tell me a little more about the Avalon 4.1? How much is it? Looks pretty cool! https://ehash.com/product/avalon4-module-1t/Its very hard to get, i had a buying thread opened for months saying i'm interested in buying one and i never had anyone PM me about it, ever. Its more expensive than the S5, its a rare unit, not many were built and the price did not really drop. In term of value i'd put it around 1BTC shipped in term of ROI, a bit more expensive than a S5 but its actual sale value is definitively higher, probably close to 400USD or 1.5BTC~ Alavon 4.1 Will be valued at closer to the 400. The were expensive when they came out and the value has came with stayed with them. They are the most quiet stock miner there is. S5 is cheaper but runs hot and loud without mod. I wish you would have asked on here before selling it. As there were some good options left to try. Yeah 2 Antminer S3+ , they are 453gh/s each so 2 would give you around 900gh/s and cost you probably 200$ while being quite while stock.
On S3 or S3+ I would avoid at 10 cents currently. Unless he gets just a huge bargin. The S3's just are not near as efficient as they once was. Cheap and "free" electricity are market for S3's currently. There are two on the marketplace right now for 75$ a pop, definitely in his price range and could have a possible resale on them locally and use them as heaters during this very soon winter covering most of the power cost until spring. The reason they are so cheap is the power it uses. Even at 10 cent's I get at current difficulty they are going to lose money even at 75 dollars each. I personally don't believe in losing money and running as a heater. I run ones that I bring over cost of electricity. But I know there are some that do. I just think makes more sense to get free heat and one you are not losing money to run. So at 10 cents yes you could use as space heater, but you lose money and price is just going to continue to dip. I would have him go for S5 (which sucks he sold) or better as far him running during winter even. |

Here is my dislike!  that crap fan that bitmain uses? Delta fans are crap? You have a very interesting definition of "crap". I think he probably doesn't like them due to noise, they push a lot of air but they aren't Noctuas and could definitely be a lot better, especially when paying for an expensive device (like an antminer S7). I'm sure it's due to noise delta's are pretty great fan's as far as CFM's. I did find I liked the sanyo better on testing with S4 on recommended fans. It just had even more CFM's going through the machine. Miners are really not that quiet anymore. You either have to older older gear or mod new gear it seems. I do expect power and cost to be bigger factors then sound as far as a business standpoint on most miners sold. |

I bought a used SFARD from ITOPSHOP, the price was good but very high to roi easilly, and i don't know where is another SFARD on sale...
It was a release a very very small number of resellers that each got 5 units. I would say not a huge launch on it at all. The price actually was pretty high on ITOP i think it was suppose to sell around 1.2k at release and ITOP was around 1.5k. So they set on them for quiet a while. Most sold long ago on what was available to public. ITOP sit on ones that didnt sell and mined them. So you got lucky to even find one. Chances of finding another store just mining with these is rare, so you chances are will have to get from 3rd party that also bought one if you want another one. I might suggest doing some ROI math though before going in deeper with them. There was a reason they sit there for so long at 1.5k |

A cold wallet that runs bitcoin-qt....
Because cold wallets are almost unhackable, and qt is the safest.
then how you do a transaction, you must be connected to the net to do it my suggestion is a hot wallet that run on a dedicated server for Core only Leaving a dedicated server running (I assuming connected to internet) does not sound like a great idea overall. It is better then those running hotwallets on machines they surf web and do lots of things on. I think cold storage is the way to go with sizable amounts. If spending money only sure hot wallet is not to bad for that amount of BTC. |

I currently make around 50,000 a day.
Is anyone out there also using faucetbox?
no because signature campaign are vastly better, but faucets for newbie like you that can't afford account, nd maybe don't have a job, or a student can be good if you can find someone that is willing to sell a bot it cna be better A bot would not last long though if used a lot. It would drain a lot of the hot wallet. And chances are if there a bot being sold for a site they would buy a copy to fix the issue. Most pay so little even if there was a bot, a lot would need to send capatcha to be done.... and the faucet pay's less then capatcha. So for most part I don't see it as a bot able region as it pay's so little. Faucets honestly are not worth a whole lot as a user, just to little pay. |

The project failed.
Their chip yield is very terrible and nearly 0% yield if you SMT several these chips in a PCB.
In this situation, they could not mass production the miners and sell them to the market.
If they successfully manufactured thousands of dual miners, how come the LTC hashrate still no raise?
Yeah....conundrum...the only thing that 'could' happen would be they are selling the chips to 3rd parties and they are running them as full out BTC.... from what I understand doing both BTC and LTC at the same time is not very efficient ....either electricity or mining wise (somewhere on this thread I think I read that) So probably they are 'recouping' their development costs in house with data hall either btc or ltc miner wise...so maybe the shoe has yet to fall I do know they probably have to 'do something' to get their (or try too) their development price back..data hall for exclusive use only would be 1 way and then when they have got what they got out of that with whatever coin they are mining (btc or ltc) difficulty wise..then I would suspect it would be the old 'bulk chip sales to china' route ..as we have seen in the past but they really are not 'tooting their own horn' like it is any kinda success thats for sure!  By the By the last time the SFARDS OP on this thread was active and posted anything was Sept 1st 2015....so yeah....its not looking like a barn buster! Hi, my SFARD unit is running in dual mode, it's draining 985w and does 1500gh/s btc and 51mh/s ltc, at same time. IT is running very fine on f2pool and does a regular 0,0124 btc/day and 0,5115 ltc/day at this difficult (60883825480 for btc and 49247 for ltc), so i only can say good things about it. BTW i was seeking to buy some scrypt miners, but is a very hard task, because the halving (last two months, i think) and because there is a lot of stuff with no profit (unless you have a very cheap electricity, or free). I live in Spain, and i have a very cheap electricity to be in Spain (0,089€/Kw or 0,081$/Kw), and i cannot run a lot of scrypt miners (i need 13w/mhs to make some money, but i only have 0,8% of profit), so i only can buy A2 chips, SFARD, KNC Titan and Alcheminer. And KNC Titan are very easy to broken, so i think there is less KNC TItans hashing now. So someone is replacing the hashpower atm (i don't know how). I don't think folk are shutting their machines off yet...mining at an 'elec loss' imho hoping btc will pop and/or take ltc with it...it may have flat-lined already...and the titan(s) will be the last to be shut off ..i have 2 of them (one orig one used have made roi) and am making 600 usd a month at 13c kwh elec at 645mh or about 200 ltc a month anyway it has not shook out yet..if there is more of a spread between ltc to btc (below 0.0100 ltc to btc) and/or the $$ for btc goes up faster then that relationship you will see difficulty drop imho dramatically...from difficulty that last couple times (9 days) it MAY already be flat-lining difficulty wise again this is for LTC to BTC conversion (my use of this mining) so anyway how it is working till my titan(s) too...eventually go to doorstops as well Just look at all the old gear that is being ran. I can't figure it out but a LOT seem to still run old gear. And there is a lot of it for scrypt. I never could figure it out on why people did if they do not pay electricity, or believed it would go up in value. Either way look at Zeus/Gaw/Hashra all pretty much the same and unless "free" power and people will lose money on most of them. But posting in here trying to buy more SFards gear will do no good. They have not been answering questions for a LONG time. And I don't expect that to change. |

initramfs.bin.SD-20141016.tar.gz is the last firmware that supports adjusting voltage. Everything after that is sabotaged by bitmain.
None of smit1237's available firmwares have voltage control, as they are based on initramfs.bin.SD-20150129.tar.gz.
A good S4 will run 225MHz at 0710-0720, average S4 will need 0725, bad S4 will need 0730 to be stable at 225MHz. The lower the better, of course. Proceed at your own risk if using the stock S4 PSU.
With the stock PSU, i'm doing 0717 @ 2.05~TH/s, its not glorious but it does put the at the wall draw at under 1400watts, not sure how much i should push it, even though it should be able to feed 1440Watts so 1600Watts at the wall. I'm not sure i trust it. Its not the stock PSU but its a replacement of the same, so... I really never did much OC on the S4's. Never went to high since I was afraid of PSU's after hearing about some having such bad luck. I had ordered during different batches so some of the bolt power and some of PCIe I always had a 15 amp 120 for each machine though. So it did not have to share with other items. I never burnt one up with regular clock so I feel pretty good about that. |

Blockchain.info is down currently, so payments will not be made automatically until it is back up!
An updated bot (likely with a different blockchain service API) will be released in the next few weeks.
I see, thanks Marco, I hope it will solve soon. It's already back up and going. It was stopped from working since blockchain was down. So not fault of bot, but luckily blockchain is up now so bot is functioning. So that is good news. It really is a pretty good bot. Really? I see on bitsig stats, my payment is not make it process yet. the stats showing my next payment is 2015-10-26 but until now it's still counting my post. Blockchain has had a few times it show to many connections to me. So if bot is getting this it would effect it. Some have worked though after it got brought back up. If it did not hit up macro or bitcoinboy. No need to worry they always make it right. |
