That is a seriously shit quote for an ASIC Bitcoin Miner  

My thoughts exactly. I wrote some great ones for their slogan competition.
But the fact they liked "bitcoin makes the world go round", I figured they'd go for something twee in the end. And they sure did.

As they are a European manufacturer, annoying to see they used a pun on the Americanism "block". The streets ain't in blocks in Europe.

There were much better slogans, they should have done a short-list and allowed us to vote. But democracy isn't very popular these days - US or Europe...

That's one way to read into it, if you really want something to be offended about.

Was "block" used as a pun? Looking it up... Drat, being a European, I didn't notice, so I took the word "block" at its literate "bitcoin block" value.

Probably more of a double-meaning than pun. American cities are built in blocks, which are roughly 80-120 metres. So being one block away from something is not very far. If you were walking to meet your friend, you might text them and say "Be there soon, I'm only one block away". So saying the whole world is only one block apart is saying it's a small world. The word play is also on the "bitcoin block" value + blockchain connecting everything in the bitcoin network. One block leads to the next etc. Well, that's what I read it to mean.

Sorry you guys don't like my slogan. The contest was open to everyone. Which would you have selected??

6-pin PCI-E should be 75W.

8-pin 150W.

[tolip_wen]

> 600 GH oc capabilities? Is that what I picked up from the hints?

You will need some modifications then. The four pcie connectors can deliver 150w x 4 for a total of max 600w. A standard 4pin molex can deliver 132w per atx specifications. If you rely on the rumored 1.4w/GH, that would give your miner a maximum theoretical of 732w/1.4w = 522.85 GH. If you want more, you´re going to have to solder some extra 8pin pcie connectors in there somewhere.

If you look closely at the pics you can see that each hashing modules already have mounting holes for an additional 6 pin power connector. They have not shown a board with that location populated with a connector though.

The PCIE 6 pin or 8 pin connector only has 3 current pins.  They both use Molex Minifit Jr connectors rated at 8 amps per pin.  3*8*12 = 288W ea.

The 75W & 150W limits are part of the PCIe standard which no miner is using, the connectors and wiring can handle much much more.  How much really depends on the PSU itself and what it is capable of delivering TO the connector.

I just realized they are 6pin and not 8 pin, took for granted they were 8pin.

Here I see 6 sockets in the PCB

https://www.kncminer.com/news/news-39

These sockets are for Serial data (SPI probably), nothing to do with current. That specification 1.4w per GHs is actually KnC's weakest point, Bitfury proved <1w/GHs and HashFast & CoinTerra declared 0.6-0.7w/GHs.

CoinTerra hasn't even taped out yet...

[pacojones]

I like the quote!  American or not 

[DeathAndTaxes]

6-pin PCI-E should be 75W.

8-pin 150W.

You can do > 200W on a 6 pin connector.

The 75W and 150W aren't the technical limits they are part of the PCIe STANDARD.  No miner is using PCIe slots, no miner is doing wattage interogation on the PCIe bus, no miner is doing a ground sense on pins 7 & 8 to ensure they are compliant. 

75W and 150W is utterly irrelivent to mining.


Hint:  Have you looked closely at a 8 pin connector.  What are the extra two pins connected to?

None on the shortlist either, there were 100's of suggestions.

Enjoy your piece of bitcoin history by being on the boards. And your prize, which was a free ______ ?

Which once again means absolutely nothing.  No miner is following the PCIe power standard.

They connect directly to the ground.  It allows a PCIe compliant device to perform a ground sense to ensure the proper connector has been attached.  All the power on both a 6 pin and 8 pin connector come from the exact same 3 12V pins.

I was just looking at the specs. I'm sure there is some definite practical use-case for this, but my first thought was "And there I thought there was some actual use for them, not just a way to sell more connector types".

Anyways... thanks for the clarification

Six IDC connecteros are for communication. Extra two will be propably used in hosted datacenter units. Extra savings on controller boards and cables

I don't think Sam would mind if I post this picture he sent last month that shows the controller board not yet populated:

What are the additional 2 wires on the 8 pin then?

They connect directly to the ground.  It allows a PCIe compliant device to perform a ground sense to ensure the proper connector has been attached.  All the power on both a 6 pin and 8 pin connector come from the exact same 3 12V pins.

To be accurate the power comes from the difference of potential between the 12V pins and the ground. If you consider what is transmitting power (electrons), they are in fact coming from the ground pins into the device and going out of the device in the 12V pins (electrons are attracted by higher potentials).

What defines the maximum power is the total current supported by the 12V pins and the total current supported by the ground pins. If the minimum of these two is below what you need to power your device, smoke will happen.

As the 2 additional ground pins on a 8-pin PCIe connector are connected to 2 of the 3 other ground pins they don't rise the power available. The 3 existing ground pins and the 3 12V pins having the same properties DeathAndTaxes is right in practice : what matters are what the 3 12V pins can handle.

Birkenstock's and socks... Wow...

lol, glad I wasn't the only one to notice that. Many assembly plants wouldn't let you in the door with sandals on. And not just on grounds of taste!  

The guy with the Adidas at least have some ESD straps attached to the shoes. The guy with the sandals probably have to stay out of the ESD safe zone.

Guys, We got an important question here... Where's our little buddy Eve? .....

You would think with all the props that KNC is pulling out to sell us Vaporware he would be here warning us more feverishly...Kinda miss the little guy
