Why u delete my post about your high rate of this company? Are u get paid?

Pretty much nailed it dogie, as usual, but I wouldn't have given KfC 7/10 communication from my personal experience; 9/10 when I ordered last year but now 4/10 at best.

Correct they refused my refund (requested before any were dispatched) and also refuse to RMA my dead die. Not to mention the fire hazard.

by  that doggie means Ker-plunk down she goes.....

heh no refunds on anything made batch 3 on (and likely no more neptune refunds anyway now that they are shipping)

90 Warranty now vs previously 1 year

large data hall now vs none last fall

much has changed since KNC went to the dark side....you could say they "BFL'd us customers" for the betterment of KNC ...heh

maybe I really don't want to win the lottery...I could end up being a real 'prick' if I had big bucks if the above slide is any indication!

just cause you win the lottery doesn't mean you'll do a BFL or KNC...its the greed monster that does it...so if you win alotta money and don't feel the need to get tons more money you should be fine money changes ppl but ppl never change money...which should happen...the old saying goes, money is the root of all evilness

AFox, did you file in Sweden? How long did the whole process take?

I hired a lawyer in my country (France) specialized in European law.
It took two weeks.
I don't know how the lawyer did it.
He just asked for the invoice from KNC, my IBAN (account informations) and my identity card.
The interesting thing, is that I paid in BTC, but KNC issued me an invoice in USD and paid me back by bank transfer in USD.

So you basically made money?   Paid 11 btc or so, and got $10,000 back (which would buy 16.6 btc now)?
Brilliant, instead of buying a machine that makes bitcoin, you invented a refund process that makes even MORE bitcoing the machine.

No he did not make money.  He paid $10k and got back his $10k in another form.

Not true.   He bought a machine that produces bitcoin not dollars (and he bought it with btc).   His refund of the machine produced 5.6 BTC more than he paid.  His refund produced 3x more bitcoin than the machine will over its life.    He did a great trade.

 All right, I give.  He's as sly as AFox.  
Wouldn't it have been easier to sell the BTC when it was worth $1200 and buy it back at $600?  You know, cut out the middleman, the lawyers, the stress etc...

maybe he could not at the time.   maybe he liked the optionality of betting the difficulty curve?  it could have went either way for him you understand correct?   The miner could have been worth than paid when they shipped also.   He received something of value called optionality.  He did a good trade and then he did the correct exit trade also, netting him more than anyone who took delivery will ever receive.

Hello,

Can someone please tell me what is exact wattage of 1 Neptune brick at the wall (in Europe) using branded PSU, without any overclocking, at stock speed (as advertised)? And what is exact hashrate of the device (average) on panel and on mining pool?
I would like to add this device to my small chart, showing efficiency of various ASIC miners. Thank you!

1720w  stock settings 5 cubes or 1 whole neptune 3.4+Th/s

Total is 2000 Watt @ wall.
(238VAC x 8.4A)
3.55 TH/s.

If by "brick" you mean 'cube' divide each number by 5.
400W @ wall
700GH/s
~1.75 GH/s per Watt
or
~0.57 Watt per GH/s


If you are interested in the 20nm ASIC itself, subtract 25% from Watt @ wall
300W @ ASIC
700GH/s
~2.33 GH/s per Watt
or
~0.43 W per GH/s

YMMV

Hi KNC, just wondering you still delay your miner deliveries just to protect the network? 

[user27]

1450w  stock settings 5 cubes or 1 whole neptune 3.45Th/s

Are you *always* stoned? Is that it?

The above is exceptionally optimistic; if your cubes run stable on the stock 475Mhz then you're looking at 0.65TH per cube. Most people are able to get 0.7TH per cube by dialing in the clocks and voltages (very simple to do in stock web interface).

The chips run at around 300w each but that's at 0.7v after VRM's which add around 20% inefficiency; so you're going to be pulling around 1800w from your 12v supply. With a half decent PSU you're looking at 1900w at the wall for 3.25TH = 0.58 w/gh or with minimal tweaking 2000w at wall for 3.5TH = 0.57 w/gh.

That's if KfC don't screw you with dead dies that they refuse to RMA and your PCI-e plugs/cables don't melt.

Hi,

Yes, we have decided that the Titan miner will be modular, similar to the Neptune miner. We will be releasing more information about this in our next news update.

ah frak.....i suppose it will easier to RMA ....(an rack them up in the data hall for the Titan data hall.....bet on it)

1/10 for ethics is appropriate.  I would have given them a 0.

I simply guess that Scrypt coins aren't exactly the best thing since bread came sliced these days. Isn't everyone more or less struggling to survive?

for people with TITANs on order..   Alpha Technologies has been delayed til September.   Race is on.  https://alpha-t.net/news/development-update-28072014/

Alpha Technologies never will and was never going to deliver a miner. They are a scam 100 %, it was obvious from the beginning.

grrrusually reads slightly better on 3 hour actually
2 Neptunes, so /2......   all our dies work, ALL OF THEM. Totally stock.
No cube has ever been opened, and no alterations on the Advanced page at all.
No PCI plugs are altered in any way. The Corsairs came with 16awg pci cables.
The room they are in is VERY HOT. It's a power closet for solar, and stays 100F in there Without Neptunes at all.
With the neptunes, it's obviously even hotter, and I had to bypass the solar exhaust fan's power leads, and connected it directly to a Corsair pci lead, so it's on all the time instead of just on during the day. It is low cfm, but roof venting is effective. It's a mess in there...
https://www.youtube.com/watch?v=_T2mziEZ42U

They did have dead dies initially, but rebooting one machine at a time fixes that for us.
We also use 220v... coming from 6000watt solar banks     don't know if that matters other than for efficiency...
I'll see if I can get my brother to borrow the kill-o-watt reader again
Even though its connected to solar, we have grid backup(Net Metering)... and even with that, when the house air-con (totally separate circuit) kicks on, it totally wreaks havoc with the Neptunes, and Sometimes causes a cgminer re-start and dead dies. When/if that happens, we re-boot one machine at a time, and all comes back. Don't really know how to remedy this without a totally separate main line. I never would have guessed that the aircon would be able to do that from a separate breaker, especially since the inverters are 6000watt each. sometimes the aircon breaker pops, sometimes it doesn't. It never used to before the Neppies arrived. Not sure if we want to add two more of these when the "Bonus" units ship.
*all the VRM temp readings on the GUI pages are about  95-100+C , while all the asics read to be around 60-70C




...and the 2 Neptune's circuit at the box


15.65 x 220v = 3443 /2 = 1721watts for each Neptune "At the wall"
 pretty close for horseshoes and hand-gernades
3.4+ th/s  each, so 3400/1721 is 1.9+Gh/s per watt or .506 watt/Gh/s  ... "right out of the box"
Now who's "stoned"?  That's figuring at 3.4, and it's actually a bit better, as you see here.
Your 2000 watt .57watt/gh/s sounds like you may have power delivery problems to me, I can't be that "lucky"

Neptune Update [...] we’re continuously delivering as many as we can produce. Deliveries have been a little slower in July but will ramp up again during August.

Translation :
We've ran out of 20nm chips in the middle of July and Batch 1 (13000$) production.
We expect to get more 20nm chips in August and will ship Batch 1 (13000$), Batch 2 (10000$) and Batch 3 (6000$) continuously.
Yes, we said that we will wait 1 month between Batch 2 (10000$) and batch 3 (6000$) but we don't care; as the more we sale, the bigger our mining farm gets.

Nice.. One comment on the VRM temps.. 85C is the max temp rating from Ericsson and given that they also get driven 10A above spec from the factory I'd recommend trying to get those temps a bit lower. Not that you plan to run them forever, but 20C over temp and 10A over current might burn them up in a few months. Some look like they are getting close to the destructive limit (125c I think).

General update for those following RMA activity: After weeks of waiting I finally received the two cubes today that I had to RMA. I hope to get them setup tomorrow.. And I hope they work. I was told my "RMA has been fixed," but I put a small X on each of them and the boxes I got back are unmarked. Most likely they are not the cubes I sent them.

Quick timeline, minus several follow ups via email and phone:
7/2 - issue reported with 2 cubes and controller card
7/8 - RMA authorized, shipping label issued
7/8 - RMA dispatched
7/21 - replacement controller card received
7/28 - 2 cubes received

I wholeheartedly agree.... but It's my brother's house...   I recommended to get them out of that closet, but there's really nowhere else for them he says...   

congrats on getting your cubes back finally
