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?  Grin

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)

1st batch Titan pre-orders now selling for ~5200 USD on Ebay.

http://www.ebay.com/itm/KNC-Titan-300MH-scrypt-asic-miner-rig-pre-order-not-Alpha-Zeus-no-reserve-/301251631029

KNC can't be selling many of these

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?

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

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.

u27
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.

Alpha Technologies never will and was never going to deliver a miner. They are a scam 100 %, it was obvious from the beginning.
Correct - here's early proof they were full of scam: https://bitcointalk.org/index.php?topic=408722.msg4472437#msg4472437

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"

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

New KNC Titanic case design released, with a subliminal message towards their competition (i.e. their customers). Can you spot it?

I do not think it's KnC. Never heard of any scrypt ASIC competition ?

And this is just the beginning.
Remember the massive increase in Bitcoin's Hashrate last October ?
Can you still spot those 'huge' jumps on a today's chart ?

What's similar when you compare those days with today's Litecoins Network ??


The only difference will be: no massive increase in value afterwards.

Well ya this is knc member? They probably just threw it in a big bin with a the rest of the crap that doesn't work...wait 2 weeks so you get screwed outta more downtime while protecting their Dc...Then finally send you another untested unit...got a 50/50 chance it'll work...so you feeling lucky punk? Hehe

You're not lucky, you're failing to measure it correctly.

The chips run 300w or so each stock; how do you think you're getting from 220v AC to 0.7v DC with 220w/<15% total loss? Fairy dust and magic beans?
