I can stand paying $500 for a Neptune in duty and taxes but not $2100. It has to be reasonable, so I will let UPS process it but if it comes to me with some stupid ridiculous price I am going to have to say NO! lol

I just got off the phone with UPS they say that KNC marked the value my Neptune at $10k, so that would be HST I believe, $1300 plus duty.

To date I have not heard of a US customer needing to pay anything extra.

It seems like you are basing expectations on foreign customs/tax laws.

I hope you are pleasantly suprised re:shipping and taxes.
2 Sat. and 1 Nep here, in US, I never paid extra @ the door for package.

Thx for sharing the order and shipping info.

Hello,

Any one tried Hashlet already? Would like to have few mhs to play with before Tity ship, any advice or review of hashlet, thanks!

https://bitcointalk.org/index.php?topic=537912.0

https://bitcointalk.org/index.php?topic=720844.0

have fun

Hi,
Bought 50MH/s for playing around, payout is fine, but still wondering am I really mining and how could they offer such profitable payout....

Will KNC do some thing to fight GAW? after Zencloud experience I'm start thinking my Tity will become like just a few thousand dollar toy for making fun.

Well I am not sure why this is but UPS receives overseas shipments in the US first, then bring them into Canada. Why the can't or refuse to bring them into Canada I am not sure. It's not like Sweden is an American country. LOL

I requested refund before they started shipping which was refused. The fire hazard miner was then delivered weeks late. RMA was refused on dead dies on the grounds that the remaining dies were running slightly over 3TH. To top it all off this is now 2/5 cubes burnt out with 16AWG cables.

KnC have two arguments in this regard;
1. Low quality cables
2. Improperly seated cables i.e. not all six pins making contact

Real world;
1. Clearly not a low quality cable with 16AWG; it's a design issue where each 50w pin is expected to handle >100w
2. As shown all three of the positive pins burnt, not just two, as it would if one of them wasn't seated properly

I have been lucky so far in that my house hasn't burnt down yet.

If *everybody* could post this link on the KnC fourms *every day* that would be good, thanks. https://bitcointalk.org/index.php?topic=170332.msg8498317#msg8498317

...and now for lots of nice high res photos:





Since KnC didnt bother to respond to me, let alone RMA, last time this happened; here's some warranty voiding nudes:



(nice to see they wrote "2014 KnCMiner" right alongside the socket so there is no confusion)

It just takes one to burn out and the remaining two will burn out pretty quickly after that as they take on the additional current from the first burnt out pin. The one making the poor contact will eventually burn if there was some contact at all.

Hii,
According to your photo, that indicat might be over current issue, so does knc offer any solution?
Some how, the single socket design could limited over clock behavior, so when the time Tity ship to my place I won't oc it.

Some how, the single socket design could limited over clock behavior, so when the time Tity ship to my place I won't oc it.

Yes, it's an over current issue alright! Over twice the current the socket is designed for was an over current issue from day one.

As for overclocking; there is no overclocking with Neptune. Everything from the power connection to the VRM's to the chips are already running at or above their maximum spec. The web interface allows users to change from 475Mhz to 500Mhz but this would not make enough difference speed wise to warrant the risk of changing stock settings.

2. As shown all three of the positive pins burnt, not just two, as it would if one of them wasn't seated properly
It just takes one to burn out and the remaining two will burn out pretty quickly after that as they take on the additional current from the first burnt out pin. The one making the poor contact will eventually burn if there was some contact at all.

In that situation you can usually see what happened; if there were two pins making good contact and one making poor contact it would be usual for the failing pin to be a lot more blackened / melted than the other two which burn out quickly afterwards. If there were two pins making contact and one with none then we would likely see two very blackened and melted and one intact? However it's neither of these cases; it had been running for a good while before it melted and all three pins melted consistently to each other.

Hi,

So this is a 10000usd Jog, and even this single socket not make trouble, sooner or later pcb board also make trouble too, then only 90days warranty, that is about the time to blow up cube even under normal working condition, so will knc offer schematic and pcb for upgrade to shoot this issue out.

That is only issue, I don't want to over clock, but it looks now even I don't over clock it, it still can't last long.

It's funny, ....

I'll tell you what is funny, these guys tried to live under the banner of "Over-Engineered" and then produced this garbage.  What a joke.  Computing the maximum load on a connector is not exactly rocket science.  The embarrassment must be excruciating.

They obviously were too cheap to build new boards to withstand the extra power flow caused by the 20nm chips. They even use the same PCB boards for the Neptune as on the Jupiter.. For a company that has a revenue of 100+million, they should be ashamed of themselves. The least they could do is acknowledge the problem  Roll Eyes

That would mean they may be on the hook to fix it.  By just saying it is 'by design' they can keep going with substandard engineering and no one will be on the hook except the miner with RMAs pending.

Tired of substandard power distribution in your ASIC setup???   Chris' Custom Cablez will get you sorted out right!  No job too hard so PM me for a quote

So what's the latest on connecting PC power supplies to the Neptune's, what is the general consensuses on what we use?

My Neptune was shipped yesterday and will arrive on Monday so I need to get a move on with respect to power. Smiley

Thanks,

I think people are recommending the 1300W EVGA, which I believe can handle 3 Neptune modules.

I use 3x Corsair AX1200i for my Neptune, which I'm planning to expand to 5 of them for two Neptunes (when I get my bonus Neppy), i.e. one AX1200i powers two Neptune modules.

There is a catch with the AX1200i.  You need to have PCIe 2-to-1 splitters to use them with the Neptune because the AX1200i has Over-Current Protection (OCP) which kicks in and shuts the PSU down. I blame this on KnC, not the PSU, as the Neptune draws more power across a single PCIe connector than the specification is designed for (that's why the safety features of the AX1200i kick in). Putting the PCIe 2-to-1 splitter cables on means that two PCIe ports on the PSU feed the single PCIe port on the Neptune module, so each PSU PCIe port is supplying power within the PCI specification (and doesn't trip the OCP).

I got my PCIe 2-to-1 cables from Cablez, and I'm very happy with the product (see https://bitcointalk.org/index.php?topic=170332.msg7579936#msg7579936). I've been running them 24x7 since July 11th with no trouble (they don't get warm).
