1) The SeaSonic has two PCIe connectors one one cable.  Don't use two on one cable.   You should have 4 connectors plugged into the power supply itself (plus mother board and molex connectors).  That means you will have 8 PCIe connectors use only one from each pair.

That did the trick, thanks. The SeaSonic cable has 6 separate 12V lines coming out of 1 modular connector, which splits into 2 separate PCIe connectors with 3 12V lines each, so I had assumed it would be ok (the 12V lines are not shared). But apparently there is a power limiter in the individual output connectors coming from the PSU.

32 neptunes left - I hope knc deliver in q1 and rain on all these mfs parades.

I hope they don't deliver until August or May. OR NEVER! I couldn't bring myself to even spend 10k when I had the chance on such a big delivery window. If a company can't boil down to at least what quarter they will have a product, then it clearly was a rushed advertisement and they just wanted to stock up on big money before the year went out. I'm a hater today.

[Biffa]

I'm just going to put this out there, but I got a gut feeling that if Hashfast deliver in December, and its looking like they will, depending on how "substantial" it is then KnC may do another batch of Jupiters.

Their policy was not to produce any more batches in December 2013, January 2014 or  February 2014 unless any of their competitors add large amounts of hashing power to the network during the same period.

Hopefully, if they do, they will be comparable in price to their competition i.e. <$4K

Let's be honest - the only reason knc are doing 20nm is to justify the ridiculous price.

I was thinking today.. I wish I'd had the spare funds a few months back to buy in when it was $100/btc.

Neptune would've cost me a grand ...

This is one reason why I enjoy the possibilities with bitcoin. Sure, the value fluctuates, but that can create some great opportunities for those already in it.

Not really, since KNC still puts the price in USD prices and still requires bitcoin. A company truly accepting bitcoin doesn't look at the USD worth at all. Trust me, weather BTC was $10 or $1000 you still would have had to pay $10k.

Kaboom! http://s28.postimg.org/v71hnbm71/SAM_1801.jpg

PSU: OCZ ZX 1250W. Found the Jupiter shut down. Tried to start it and nothing happened. Removed cables, put them back and poof fireworks. Waiting for my RMA.

Hashing with 3 boards and not whining.

Has anyone tested soy's theory about the 3.3v filter caps on the PSU being the issue causing max current to be delivered and blowing caps?  I wanted to but I have no way of measuring more than 10A without frying my mulitimeter so its not a good test.

By the by I received my RMA board back yesterday and everything works great!  I did put a 2w 18Ohm resistor on a 3.3V line just in case but who knows really.  Thanks again KnC!

I would suggest if you shut down your PSU for anything, unplug it and give it 10 minutes before starting again, just in case.  A bit of paranoia is better than straight up gambling I think.

The ramping of current on the 12v line isn't theory but said by the tech rep from the VRM manufacturer.  When one of two engineers designing a switching-servo-amplifier that I was breadboarding as a technician around 1977 designed the then novel switching scheme while our US company was a division of Kollmorgen, he having gotten his degree from Brooklyn Poly Tech,  the triangle wave which to a comparitor input would see a lowered DC voltage on the other comparitor leg (that voltage the feedback) until the top of the triangle wave was encountered at which point the output would swing from one rail to the other for the duration of the interception.  When the lower voltage (feedback) would reach the triangle wave and the output swing from say zero to full voltage, the controlled voltage would increase raising the feedback voltage level above the triangle.  Typically to maintain an output voltage at some current the comparitor would have the feedback level at some stable level intercepting the triangle wave producing a square wave with the necessary duty cycle.

The triangle wave was produced with a current source charging a capacitor then discharging the capacitor.  Voltage charging a capacitor happens at a changing rate over five time constants.  Current charging a capacitor, or current discharging a capacitor,  will result in a non-curving slope; charge/discharge will give a triangle wave, not an approximation like if you only use the first time constant but a linear charge and discharge.  

That up-ramp of current on the 12v line would follow a straight line, a non-curving slope.  That rise would be dictated by a voltage produced elsewhere by a current source charging a capacitor, that would not  be a filter capacitor.  

There would be an internal filter capacitor on the 3.3v line.

My theory is that the up ramp for the current would be perhaps between 0v and 1v produced using the 3.3v rail because the 3.3v rail would have established itself before the 5 volt rail or the 12 volt rail, and that with no load on the 3.3v rail, e.g. no motherboard in place and a jumper on the motherboard plug, the up-ramp charged capacitor might not be brought back to 0 volts but remain at 1 volt or the full current condition.

One way to disprove that element of my theory, 3.3v rail getting stable before the 5v or 12 volt rails might be shown or not by someone with a nice fast sample and hold oscilloscope and a camera.

Ah, my failing memory is showing.  I meant not sample and hold, which is a common circuit for sampling a voltage and holding it for some reason,  but a scope with memory, then triggering the sweep at startup and multiple probes measuring the voltage rise curves, see what happens when to each voltage at startup.

Uh.

10 btc purchased at $100/ea = $1,000 my cost.

1 Neptune = $10,000USD, which at the time of availability, would've been 10btc.

10 btc sent to KNC = $1,000 my cost.

What are you missing about this?

I believe KNC is geared-up already and just waiting for the competition to release.

But... and here's the kicker... KNC will be shipping only Jupiters (no Saturns)from stock or with a very short build time.  Remember, no one else will be shipping orders made today until March/April at the soonest.  Therefore KNC will be pricing accordingly, easily double your $4000 guesstimate.

Bitfury did the same thing.  30GH/s boards were $500 two months ago but are now $1000 each.

Hash power today is worth MUCH more than hash power in 3 or 4 months.  And no, the cost to produce a product has no bearing on its price as long as there is a demand for that item.

They shouldn't, because they said if they did ship again, they would do it at a discounted rate.

It's presumed a Jupiter wouldn't cost 30% more than it did weeks ago, coming from the same company, using stock they already own which isn't being used.

And if they did do that, a lot of their "loyal customers" would get very hot very quick.

Maybe you're right. I certainly hope you are!  Bitfury is taking quite a beating from past customers for their price gouging.  And to make it an even more bitter pill to swallow, they had plans to sell boards for $350 before the price of bitcoin went through the roof.

So don't discount the importance of the price of bitcoin.  It makes sensible people do irrational things.

What I'm trying to say is KNC prices their gear in US dollars. Doesn't matter what the price of bitcoin is. When you go through the checkout process how ever many bitcoins it takes for that invoice to equal $10k or $13k is what you will pay. I'm being specific to how KNC does business, I understand is BTC lowers/rises and all that.

Some people don't get the idea that trade differential is a valid investment strategy. It drives me nuts. Bitcoin is a form of currency, i.e. a unit of exchange. If you use your brain, instead of "pure" idealism, you will always make the best exchange you can at any given moment.

Bitcoin is not going to replace the dollar. A cryptocurrency might in the future, but I doubt it. It does, and likely will continue to, work as a secondary currency and as a store of value to some extent. Not as good as gold for that, but better than most anything else right now. It's advantage over gold is that it can be transferred nearly instantly.

There's nothing wrong with your math or your thought process on this.

too bad bitpay isn't a little quicker on tracking up ticks of btc value, e.g. fewer btc to equal the cost.

Yeah.. some people just get it and others don't I suppose. I see this type of technology as a wave of the future for stuff beyond our dreams. Right now, we're in the embryo stage really. Today a cryptocurrency, tomorrow.. who knows.

No, because an alternative would be to sell those Bitcoins for $10000, so the Neptune is still costing you $10000.
It doesn't matter at all what price they were when you bought them, it matters what they are worth now.

That's one side of the coin, the other side is you are still only $1,000 fiat into the hole. Whether you cash it out or buy $10,000 worth of equipment, you're still only initially out $1,000.
