you have some eligius stats now ? |

I can't imagine letting one SP10 running around me. If you put it on your balcony, the neighborhood will hate you.
can anybody post decibel reading of SP-10 at 1.4-1.5 th/s within a feet or so? There are free android and apple apps that do it. I am just trying to see how noisy (or not) it is in comparison with S1. What ambient temperature would Sp-10 tolerate? i have an extra room, but when i put 3 S1 there and closed the door, temp rose to ~35 degree celsius, so I had to open the door. obviously, if SP10 is like a rock band, it would be difficult. I figure that heat-wise 1 SP10=3 S1 (with much higher productivity for Sp-10, of course) it's max 35°C ans as said by SP-Tech it can run with ambiant air @45°C (they said it worked for them). Don't go to hot or you will lose a lot of hashrate. Plus, I want to say that if air go in @ 22-23°C it comes out @45-46°C. You must evacuate all of this hot air. I bet you can do something fancy with this hot air like powering a Stirling engine  The noise is about 70 dB within 3 feets. It's like 3/4 vacuum cleaner at the same time and I underestimate the reality. It's a high pitch fan noise. |

Bitcoin is supported by bunch of what(college kids?)
No, the average age of Bitcoiners is over 30 years. What Bitcoin is supported by is a decentralized open-source network capable of over 60 petahashes per second, the most powerful computer entity in history. As trolls go, you're pretty lame. Try again. all that power and it's only capable of a limited amount of transfers per minute and has other scalability issues as well when I wire with the banking system it takes 2/3 days and for some people it can cost up to 1$. wow, such speed; so cheap ! |

Yes , that would do the job for sure, but your bill would go high to the sky. It consumes alone around 3kw. I would suggest to build a nice small insulated kiosk and use fans with filters to circulate the air. You can leave it at the balcony. I can't imagine letting one SP10 running around me.

you're wrong about your line. you need to use a logaritm function in order to stick the market history... hint : weight the historic market for a given period then you have a "dot" wich will represent the price of btc. With all the dot you can generate a log function on excel. magically, you have a trend. long or shot trend depends on the period each dot represent and how many dot you have from then to now.
you can now speculate. have fun and go burn in hell.

Big finance will jump when it'll be worth it mean that the price of btc will need to reach the price of gold for good speculation. It will be also needed that important retailers use bitcoin as a payment system such as Amazon, Wall Mart, ebay, Paypal, etc. I believe that France will also make the price go up : Monoprix wants to implement Bitcoin payment till the end of 2014. We are talking about thousand shops... with million customer each weeks... http://bitcoinconf.ru/en/french-retail-chain-monoprix-accept-bitcoin-payments-yearbelieve it or not, mine or speculate, the bitcoin is on the way... devs just need to lower the fee (1 or 10 satoshi) to make it viable. |

Never mine at ghash.io, too high maintenance fee (29%) currently. Btcguild, eligius and slush are the best.
[edited for spelling]
elaborate on maintenance fee ? I've 0% fee right now and I withdraw@0.001 |

Those guyz are posting in mining speculation and they tell you to don't mine. Don't listen to them. Do your maths and enjoy.

FYI, I noticed a drop in hashrate. Thought it was bad luck but the hash rate dropped a bit everyday. After a reboot, I'm back with fantastic hashrate : quiet mode runing @ 1.4+ TH/s and normal mode @1.55+ TH/s (one hour stats).
I advice a reboot -done in 60s- everyday for optimal hash rate.
Running version 1.2.35
I didn't see such system behaviour. It can be related to the way the pool computes hash-rate. Can you send me image of your hash graph to zvi@spondoolies-tech.com? Regards` Biffa was right, i have bad stats again on the pool... the graph on miners show that the units are definitely stable and there is just a variation of few GH... I'm waiting for the power consumption graph from the DC tech team to confirm but I'm pretty sure that I'll switch pool. However I'm currently mining on ghash.io and I tcp ping @ 100-170ms. On eligius I tcp ping @80-90ms. I'm gonna try eligius and confirm to you. for now, much much better : http://eligius.st/~wizkid057/newstats/userstats.php/13NWuCfiWzNxku12tJ2z6hRWVW2pZhUBpZ |

last diff : ~0.3 BTC / day @ 4.2 TH/s (real experience)
new dif : ~ 0.28 BTC/day @4.2 TH/S (estimation from what i mine since the new diff)
hope it helps

I like these stats sir.
Do you own an SP10?
Is TURBO mode an overclocking mode?
Does it require extreme low temps to operate properly?
Thanks again for the post, I like POSITIVE info on equipment
THEY HAVE SHIPPED and so far anyone Ive seen post on the
SP10 is higly praising their product. Im impressed so far sir!!
TURBO mode is the most powerful firmware setting, which can easily be chosen via the webinterface. It will get the most hashing power out of your unit, with a slight increase in power draw and noise levels (fans run at max) The sp10´s firmware does dynamic frequency control for every chip, based on that chip´s temperature. This ensures every chip will perform to its maximum without getting damaged. The lower the ambient temperature is, the higher the chips will be clocking. Very good results can be achieved at normal DC temperatures of around 20°C intake temperature. Therefore i would describe the cooling requirements as quite reasonable. If you somehow have a facility with free aircolling like a forum member in Scottland, and can achieve 5°C, that really puts the "pedal to the metal". However, you will typically get very good results with standard operating temperatures. @wanna4fun: What is your intake temperature (and where is your DC located?) Did you switch the PSU for a 1250W model? @hardhouseinc: Yes I own 3 SP10 and i'm really happy with it ! @collider : intake temp : 21°C +/- 2°C from a cold corridor (I came with my thermometer). I believe I have a standard PSU. |

Stat from pool (ghash) one hour stats : SP10 with proper cooling quiet mode : 1.30-1.4 TH/S, normal 1.4-1.5, turbo 1.6-1.8 Th/s (depends on luck). Edit 24 hour stat quiet : 1.3 TH/s normal 1.4+TH/S turbo 1.7 TH/s stats from datacenter's PDU @235V : quiet : 1.2+kVA normal : 1.4+ kVA turbo : 1.6+ kVA This stats are an average of 3 different units for 24 hours. use this tools to make the math to convert in kW : http://www.olympianpower.com/tools/kva-calculator1 SP10 turbo mode = 1 Cointerra IV ? please confirm  |

pics, vids, review by dogie (to quote only him) and i will look further |

I've been shipped ! I receive 3 SP10. They said mid-april starts the delivery, i received the DHL tracking the 17 or 18th of april. I trust this company. |

Hi timmah,
i've done some temp measure at the bottom, it reach the 65-75°C very easily with an ambiant temp @ 22-23°C.
Without any heat sink or expensive add on to the miner, just think about a wind corridor which will extract the hot air outside.
On one the side of the box (the "in" air) you'll want cold air to go inside your miners. You can mix the air from your room + the air from an AC to cool them down.
You'll also use check valve to be sure the air is properly sucked into the units. not easy to make but worth it. I believe it can cost you 500/600$ to achieve this (a lot less than immersion star treck things).
I tried to do this but had issue with the space in my apartment so I couldn't make the wind corridor and i had to change my mind.
If can enclose the miners well enough you'll be also able to kill the noise with acoustic foam. Btw, don't hope to do this into your living room, but an empty room (far from the center of the house) or a garage would be the perfect place (if secured enough...).
