Mostly 3 phase 60 Amp and 20 amp breakers. All in refrigerated server room. That's what I've been thinking about. In addition to 240V/50Hz single phase we have 400V/50Hz three phase (= 3 x 240V) here in Europe. How did you use three phase current to cable up mining rigs? PDUs? Or just all three single phases for discrete circuits (which shouldn't be a problem as long as load is equally spread across all three phases)? Basis Distros which have 3 20 Amp Breakers. We also have a few UPS systems that accept 3 Phase and output on 15 and 20 amp circuits with UPS. Our space was custom designed for film and video production, so the power lines were chosen to run the lights... 15kw, 10kw etc. Strato |

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, which will follow the rules of the network no matter what miners do. Even if every miner decided to create 1000 bitcoins per block, full nodes would stick to the rules and reject those blocks.

Wow, the timing of the S4 release could not have been worse for Bitmain and miners looking to buy a S4, and it's mainly just bad luck outside of their control. The price of BTC is down to $400, and we're also looking at another 15%+ difficulty increase in 6 days.
I expect the price of a S4 to be between 2.5 and 3 BTC ($1000 - $1200), which will make ROI in BTC very difficult...

Which might mean that the next time the difficulty might stall or maybe even *shivers* drops! |

BTC price is still going down, no ROI in sight at these prices.

No need to worry OR sell He always does it...so was turkey thinking when that nice human was giving it food twice every day... On a more serious note, peak in 2011 was ~$35, then it went down to $2. The equivalent on Bitstamp would be from the peak of $1150 to $66, but since at the peak of 2013 bitcoin was not as technically overbought as in 2011, there is a good chance that we stop either at $340 or at $250 (april 2013 peak). |

This is what I saw also at $520 and bailed out of the game while I was still above water. The ONLY reason that(a profit) happened is because I sold my equipment at a price that still wouldn't ROI. On Craigslist in on day btw. There will be a point when that bonus is gone do to a broad and sudden shift in mining perception. The mind tends to fill in the missing pieces optimistically when it comes to this type of thing(lottery mentality) yet keeps a blind eye toward the facts. Every facet on the btc diamond is ugly right now. Falling btc, increasing hash and difficulty, no game changing hardware jumps on the horizon, lots of hardware in the pipeline, bad btc press, lackluster adoption rates.
The only equation I had to work out was how efficient of a room heater my S2's were. Take the $1000 each on the S2's (Aug 31) and just heat with space heaters or run S2's continuously and dip into my solar net meter credits. Even at <10% diff increases and no btc value loss the sell option was still the best.
I'd only get an S4 at below $750 per, and that assumes btc>325 and a typical diff increase. Even then I'd only expect to have a free miner and $130 profit after a 140 day max ROI.

Please sell your equipment! If you can only think in BTC terms then you are better shut down your machines! I made 0.025BTC/day with 500Ghs this month! Thats 0,75BTC/month! If you know how and what to mine then the possibilities are infinite! |

Well, end of month is next week so they are not late... LOL, but it doesn't bode well that they would be late just providing us with the sales info... Maybe end of the week for them means Sunday, not Friday. Of course they seem to update their site during working hours in China, so maybe we have to break out a world clock app or site and set an alarm for 8 AM Sunday Beijing time  |

What will the potential noise level be on these S4s? Anyone have experience with the S2s for comparison?

I contacted Bitmain to ask the price on the S4, they gave no answer but to "keep checking the website this week".
