still looking for the db meter. getting too much gear in the house.
I am running 10 s-3's and 1 sp20e
I have 9 s-3's in the garage near the work bench and I have the sp20e
Figures I set the gear all up and temps jumped to 74f . making the attached garage 92f and making the house 85f had to shut gear off over night to be able to sleep.
Today is cooler around 62 f house and garage are both better.
I will photo setup.
@ sbogovac raskul was helpful in selling it to me.
@ raskul thanks. and I am send some more hash at mmpool
3 s-3's and 1 sp20
they stack well and air is feeding out my garage's back door 2 quality psu's the egva 1300 g2 and a seasonic 1200 watt plat.
my garage can safely do 5k watts I have 5 20 amp 120 volt circuits into it. when i am running all 10 s-3's and the 1 sp20 I am at 4.kwatts
for now the issue is heat since it is about 57f the garage is warm but my entire home is also warm. So realistically I am close to max. my hashrate is 5.5th .
I could fit 2 more s-3's or try to arrange a few more sp20's . my 10 s-3 to 1 sp20 = 5.4th 4kwatts
should be 5 s-3's to 3 sp20's = 6.5th same 4 kwatts.

I wonder if someone had adapted a garden box (wooden or plastic) or a small shed to put miners inside. If you have done this with any miner-let me know, I would greatly appreciate it. I am looking for a solution like this so I can enjoy Sp-20 or some other miner(s) outside of the house-I have small patch of a garden, so I cannot put a large shed in. Garage would not work for me because I live in a 40-50 house gated "community" and I don't want people who walk around to peer at my equipment constantly. |

With all due respect to Guy, this will never work for a simple reason that there is absolutely NO incentive to EVER use mining contracts vs buying bitcoin outright (in OECD countries). With the price of bitcoin approaching the cost of production for marginal players, all profit of such contract will be retained by the cloud mining company. I looked at every single cloud mining operation, and basically it is just a license to lose money (for buyers of such contracts, of course).
In theory, cloud mining has to prove that buying such mining contract will result in the GUARANTEED lower price per BTC acquired than could be obtained by buying bitcoin on the open market. However, such proof does not exist at the moment and is unlikely to exist in the future as well. Case closed.
People say the exact same thing about buying miners and have been saying it since GPU mining. Cloud miners have lower up front costs involved due to not needing to ship all around the world and they generally have cheap electricity decreasing running costs. In that scenario, if cloud mining is unprofitable, then buying miners is even less profitable for the majority of people. Cloud mining will attract a different breed of people than mining with physical hardware. Cloud miners will be less hardcore and more likely to jump ship at the first whiff of unprofitability. They would probably have no notion of the concept behind p2pool and would have no qualms about pointing their hashes at the most profitable pool even if it were the largest pool with over 51% of the overall hashrate. While I agree with you about cloud mining and I think it is bad for the industry it looks like it is the same as the weather . We can talk about it as much as we want but we can't change it. I don't see anyone refuting my point that cloud mining (as is) cannot provide any advantage over simply slowly buying BTC. Mining is fun at home, much less fun at a hosting site or colo and completely meaningless in a "cloud mine"-it does not reward either your soul or your pocket. |

Here's some quotes from Guy: Home mining is not going to be around much longer though. The big mining farms are making it so you cannot compete or get ROI. Whether we like it or not mining is moving to the cloud. There will still be some home miners, but not many and most will be in the cloud. We believe that 2015 will be all about mining contracts. Mining contracts backed up by real hardware. I agree with Guy. With all due respect to Guy, this will never work for a simple reason that there is absolutely NO incentive to EVER use mining contracts vs buying bitcoin outright (in OECD countries). With the price of bitcoin approaching the cost of production for marginal players, all profit of such contract will be retained by the cloud mining company.

Is it really 60+ db?
not under clocked see my settings above I spend 746 watts and I am getting 1350 gh or 0.55 watts per gh this allows the lowest fan setting 40.. give me an hour to find my db meter. right now I love this piece of gear……….. 746 watts for 1350gh out fucking standing. That is pretty damn good my friend. Yes it is, but it actually matters most at the "final stretch" of the miner lifecycle. Unless it is a hobby, which it IS admittedly for most of us at current BTC prices, then don't you want to try to produce as much as possible as soon as possible? |

Is it really 60+ db?
yes, what is db reading when at various watts, including default? In addition, please post about what kind of pitch it is (low, high, etc.) and, if you can, compare the noise of S3, S4 and Sp-20 if you don't find the db meter, just use iphone or android phone-there are free or almost free apps that do it Thanks |

The SP20 can be under-clocked to ~0.5 J/GH, depending on cooling and specific ASIC batch.
Cooling? Ambient temperature. any specifics? it has to be hot (>25C), cold (<18C) or in a specific range? |

Due to a technical issue, some eBay customers may be having difficulty selling on the eBay website. We're working to resolve this issue and apologize for any inconvenience. Please try completing your transaction at a later time. Thank you. yeah, right, website where you supposed to sell does not allow you to "sell" I speculate that this has something to do with their eagerness to embrace bitcoin...no? |

Pm me if they still good. i will get them all
These coupons are good until 11/30 |
|

I predicted 160 days I will change to 200 days.
It would be interesting because at ~100bil difficulty my electrical costs would =mining revenue from S3, assuming BTC at the same level and NOT counting savings from heating, which is probably a correct approach since we are talking about April-June 2015 period. |

Ok, it looks like I was wrong. Thanks for the links.
Ok, glad to help. |

“It has to have intrinsic value. You have to really stretch your imagination to infer what the intrinsic value of Bitcoin is. ”
It is such a nonsensical statement. What is the intrinsic value of internet www or TCP/IP? The ability to send money or other value eventually anywhere anytime for a small fee and have it confirmed in ~10 min has to be worth something. |
|
|
|
The point is that you need to give them free the cupons.
I don't "need" to do anything. coupons are free, but my time looking at messages, etc is NOT, hence a small $$ fee. If not, fine, they will go to waste. |

Contradict what? You were saying how they did not have access to Atlantic....because it is "frozen shut for much of the year"
I showed you a link that says..."ice free year-round" in Murmansk and Atlantic is "around the corner", so grow up and say "thanks", buddy...
And I showed you a link that says under common usage "ice free" does not mean that there is no Arctic sea ice. "Ice free" regions can contain broken ice cover of varying density, often still requiring appropriately strengthened hulls or ice breaker support for safe passageHow can the entire Russian fleet navigate from Murmansk to the Atlantic if most of its ships are unlikely to have appropriately strengthened hulls or ice breaker support for safe passage? <TL;DR>snip You have to check correct wiki articles. http://en.wikipedia.org/wiki/Northern_Fleet"The Northern Fleet includes about two-thirds of all the Russian Navy's nuclear-powered ships."
"The Northern Fleet was considered secondary to the Baltic and Black sea fleets until operational responsibility for the Atlantic Ocean was shifted in the 1950s because of more direct access."
"The Bellona Foundation indicates the Northern Fleet main base is Severomorsk with six more naval bases at Polyarnyy, Olenya Bay, Gadzhiyevo (Yagelnaya/Sayda), Vidyayevo (Ura Bay and Ara Bay), Bolshaya Lopatka (Litsa Guba), and Gremikha. Arktika nuclear-powered icebreakers are based at Murmansk. Shipyards are located in Murmansk, Severodvinsk, Roslyakovo, Polyarnyy, Nerpa, and Malaya Lopatka. Spent fuel storage sites include Murmansk, Gremikha, Severodvinsk and Andreyeva Bay." Moreover, here is something else: http://natocouncil.ca/russias-resurgent-navy-assessing-the-northern-fleet/Moreover, unlike the American and Canadian navies, the Northern Fleet’s surface vessels are able to navigate through Arctic waters. Russia has the world’s only nuclear powered icebreakers, with five currently in service and one being constructed. These icebreakers can clear a path through floating sea ice for the Northern Fleet, allowing Russia’s fleet to operate freely in Arctic waters. |

Putin is Evil but not stupid. He knows he can get away with annexing Crimea, there's nothing the West can do about it. Ukraine has always been under Russia/Soviet's Sphere of Influence. It's their backyard/frontyard/sideyard or whatever. Ordinary people be damned. Ordinary people are stupid, have you heard that majority of Russian people are supporting their dictator right now?
james, can you explain to me the motivations of the US and Russia's involvement in this situation? I've so far had a hard time wrapping my head around that part. Your post indicates a perception of Putin acting out of greed (a trait of being evil) and I just want to know how it's different from what everyone else is doing there. I am not James but I can try to explain Putin's motivation. The Crimea was part of the Russian empire for hundreds of years and part of the Soviet Union after that. It wasn't until 1954 that Khruschev made it part of the Ukranian S.S.R. After the break up of the Soviet Union, the now independent country of Ukraine agreed to give up its nuclear weapon arsenal and the Russian navy was allowed to keep using its base in Sevastopol on the Black Sea (in Crimea). Thereafter, NATO expanded to include certain Eastern European countries. Ukraine has been split between the western Ukranian part of the country which is majority ethnic Ukranian and Ukranian nationalist and southern/eastern Ukraine which is majority Russian ethnicity in many areas and more pro Russia. Putin's actions may be based on mistrust of the west/the new government that just took power in Kiev as well as a desire to protect Russia's interests in the Crimea. A desire to look strong also probably plays well on the home front. I don't think all out war is likely however. Years ago I heard the Russian navy's base in Sevastopol on the Black Sea (in Crimea) was the only easy way the Russian navy could reach the Atlantic. Russia cannot give it up without giving up it's only easy route to the Atlantic, so it's unlikely it will back down. Russia has no direct outlets except on the Pacific Ocean and the White and Arctic Seas. To reach the Atlantic, the ships must travel along devious routes: in the north via the Finnish Gulf, the Baltic Sea, and the North Sea; in the south through the Black Sea, the Dardanelles, and the Mediterranean. In its early history, Russia's only ports were on the Arctic Ocean and frozen shut for much of the year. I don't know about anything else, but you need to freshen up on your geography lessons. I have one word for you: Murmansk "The port of Murmansk remains ice-free year round due to the warm North Atlantic Current" "Red october"... http://www.youtube.com/watch?v=AWPBr4L1eyEThese Wikipedia links contradict you. <TL;DR>.
