WEll, everyone have fun with their overpriced 20nm miners, i don´t think you will ever make it to ROI city.
The only one getting anything out of this is KNC, as they can now deploy 20nm on a large scale in their Data Center.
They will probably set up the chips at a lower clock speed and higher efficiency there, as i don´t really think that they have managed to build SUCH a shitty design on 20nm that it only gets 0.7W//GH.
If they had, well it is purely a waste of Silicon.
I bet Bitfury is laughing at them right now from atop of his mountain of 55nm miners on 0.78W/GH and 1/5th of the NRE.
Yup. Free mask set and better chips with better power consumption and better density for them at the cost of the customers. Great play KnC! I hope they go down same as Avalon and BFL! |

The Bitcoin software, network, and concept is called "Bitcoin" with a capitalized "B". Bitcoin currency units are called "bitcoins" with a lowercase "b" -- this is often abbreviated BTC.

Each Neptune Cube uses a high-quality PCI-E connection and draws approximately 300 watts at it’s port300 x 5= 2100?  |

OK, so these Dumb Fc*** only included one power port on the board.
6 pin at typical 18 awg wire is probably maxed at 300 watts, 20 awg wire is less.
If you have a nice aftermarket set of 6 pin pcie power cable like by Maxfinder those are 16 awg and can handle probably 468 watts on good Molex connector that is rated 13 amps.
Solution would have been for KNC to make 2 power ports or include custom 16 awg power pcie cable. For 12k a miner they can afford it to give their customers.

These ports are fan-cooled and can handle the power, but make sure you’re using high-quality PSU:s, connectors and cables. Be careful when inserting and removing connectors as wear and tear may damage connectors. The act of inserting/removing cable connectors into ports degrades connection surfaces every time it’s done and should be minimized. That should really help the fires to grow quickly by feeding air directly to the hot spot.  |

I think many things at KnC went very wrong. THey have built their DC, designed the chips, are facing a mounting number of refund request plus who knows what else. I think they are going down the slope and customers cannot expect anything good from them. It is not possible that in todays modern market a company which had promised success to it's customers and has the technical capacity to make ensure at least figures very close to ROI are simply cheating abusing the trust of their customers. How many times they have failed? With the Jupiters, extra modules then super Jupiters now with the Hash While You Wait.
THey are just milking their customers.

Have you ever touched the Jupiter controller board? Not even lukewarm. So it's probably using far less than 100 watts (wild guess). Now touch a VRM on an ASIC board. Scorching hot! |

What do I win? [BTW, I want to go on record predicting KnC will turn in to another Avalon, with general praise for their first batch/gen being roughly on time and more profitable than hoped for, yet failing to deliver on the next batch/gen in time for any chance of profit.
[..]
Its not gonna happen in Q1 and most likely not before the end of Q2. And it wont be profitable (btc denominated).

It's definitely sketchy, and perhaps in some countries illegal since they are formally asking their customers to run a Power supply significantly out of spec to the point where it is a fire hazard. Perhaps they ran through things with legal and have confirmation that they will not be liable if there are issues, but it puts customers in a tough position.

I have it running now (I guess I'm the first...)
It does: about 3.3 Th and 1950W at the wall (the internal ASIC-monitor gives about 1440W...I have no idea where the difference is going to).
The chip is running on 475 Mhz (and can be set to 500 {not tried yet}).
There is one new thing on the controller-board: on plug-6 there is a small display-board which gives info about the IP-address and Hash-speed (very nice)... but this means as well that 5 boxes is the maximum.
The one PCE-power plug isn't running hot {the fan is indeed pressing air through the hole}, but the cables are 44 degrees Celsius.
