I don't know diddley, but from what I remember, these guys programmed their software, I imagine they have a "turbo" at your own risk button, jumpers  voltage setting something.....

Thanks, since you want to be helpful, but why speculate if Bitcoinorama could clearify it. (edit: 'not allowed to disclose' is ok with me, too)
I'd be happy about a short yes or a little disappointed about a short no from KnC or Bitcoinorama - but unlucky with an ignore of my serious question.

I assume I'm not the first one asking and not the only one asking as it concerns the ROI of all customers, no?

Possibly with some soldering overvolting is possible. Or if it's got external clock...

> 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.



Something about this doesn't make sense.  Why would KnC cap their ability to 600w?  Back when they knew their chip was at least 100GH and the assumed rate was 1.6w per gh, that would be 640w needed for four chips.

KnC isn't dumb, before they ship I'm sure they will use 8-pin connectors if they need them.

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.

They didn't.  The power circuitry can handle substantially more, the 6-pin pcie connector rating is *worst case spec*, which doesn't mean that connector manufacturers can't exceed the spec.  There's also an unpopulated spot for another 6-pin connector on the PC board.

Sure, all they have to do is plug one up and read the numbers for 5 minutes... is that it?.. no

My guess is They are getting a baseline from multiple rigs to ensure that when they announce the speed that the Crumbs of the world don't criticize them of lying due to speaking too early about the average of their machines.

If one thing this weekend should have taught is that alittle patients goes a long way..

Patience even

Damn you Google swipe...you fail me again!

That is a seriously shit quote for an ASIC Bitcoin Miner  Huh
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??

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.

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?  Smiley

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 ______ ? Wink

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

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