Its worth it is you know how to build your own ASIC, but don't risk buying if you don't even know where to start..
Well, I got this reply from Liam when asking if anything other than the low res ball map would be published.

A high resolution image of the ballmap and all schematics will only be provided to those have purchased the chips.
Thanks

So we have to lay down 5.5K just to even be able to design for them.
That blows. If a GB gets started it only needs to be bought once to be in the wild
Strange I got the same answer from both cointerra and hash fast 3 months back.
A lot of people are mad @ Avalon , but in terms of chip info the thing were always ok.
Black Arrow and bitmine.ch doc were good written and available before chip release.
Bitfury was ok.
And spondo documentation and engineering support is outstanding.
All this from board design perspective

However if the chip can do 190GH and it was downclocked to 133GH in the 2013 deliveries, while being shipped with both cooling and VRMs with room to spare, does that mean that KNC used them in their DC "overcooking" them? (KNC would have unlocked the firmware). That way they had 190GH out of each chip and not the 133GH they shipped to their customers...
If that was true... Well, it's interesting.

Is that with four chips?
Yes (can't be otherwise). 133GH/chip, if every chip requires $150-250 in VRMs alone it's out of the market already.Which is why the chips have been sitting on the shelf and are being sold. KNC have the scale, all the design done and just need to press the button to have them made into more Jupiters, but they're not.

You could probably find some cheaper design alternatives at those loads however, remember they only used half the VRMs for most of the October units. Then again why would anyone bother trying to get these on boards even if they were given the chips for free, considering the hardware will be obsolete by the time you have something working. Wouldn't mind one for a key chain though!

That's a lot of Amps. Is that the reason why it isn't being done? (or is it feasible?). I hope they can run at something near 1W/GH or they are useless for most of us.
The point is what hashrate will we have @ 1W/GH

Got my October Jupiter running at 535GH/s@550W (at the wall) for the last 2 months

this would reduce the BOM for the VRM from ~ 250USD to about 140USD
Are you saying that KNC likes to pay more? Edit, ok, it's because KNC likes to over engineer it.The gerber files from HashFast Evo boards are free from months and yet by this point only peppermining manage the make a working board for the GoldenNonce 700Gh Chip.
I've never found them publicly. One doesn't really need to be a genius to take the blueprints from HF and make their boards. They are only expensive, but still almost competitive. I'm also sure that HF would be happy to sell everyone chips at $0.2/GH.
I'm not going to read through the whole KnC thread, but my understanding is the FW is closed and no voltage adjustments are possible.
Is any hacked FW available, and has anyone made posted any information on max frequency and power draw at various voltages?

Hope that Mr. Teal find out more about the chips and the original KnC board, build his own version and see some 400Gh mining board at 200 USD 
( like he did whit the HF Evo Boards)
( like he did whit the HF Evo Boards)But at 1.5 to 3W/GH, I don't think the market would appreciate even $0.5/GH. Assuming these can get turned around in a month, the rest of the market will be closing up on that price.

I actually asked him earlier today on advice for the power stages since he has more experience with the IR3550 ( like he did whit the HF Evo Boards)

Is that it?
No documentation on the pcb design they have?
No in depth chip information?
Just those three pictures?
If so that is woeful.
they've publicly said only documentation on the chip will be made available.
but to be honest i think this is only interim docs while they scramble to prepare the formal ones.

I did the same thing asking of only documentation on pinout and protocol
And received an almost word for word reply.

Yeah, that's a pass (not that I was going to anyways). Seriously though, why don't they do what the rest of the world does and offer at least partial documentation contingent on a proper NDA being in place?
