Official BITMINE CoinCraft series 28nm ASIC miners thread

[giorgiomassa]

They have some bug in their payment mechanism which they have asked to disregard, so your payment made it through. However, they are resourced to answer any inquiries promptly. You need to appreciate the fact that you invested quite a lump of monies and will be treated as such an investor aswell. So mail them.

They do not respond to emails too  

I have to call   I prefer it by email 

We're sorry about this, due to an unexpected explosion in demand for our products, we currently have a backlog of about 3 days in e-mails to be answered. We hired more staff and the backlog is getting cleared now, please be patient.

Thank you

well, good to hear that explosion wasn't in your Bitmine

What are you guys thoughts about this hardware VS the Black Arrow stuff?

[Syke]

What are you guys thoughts about this hardware VS the Black Arrow stuff?

This looks overpriced.

[Bicknellski]

What are you guys thoughts about this hardware VS the Black Arrow stuff?

Price, heat, chip package and delivery date.

All factors you need to consider when you do the comparison.

I want to know the answer to this:

Maybe some one can light me in the right direction with the upgrade modules from bitmine.ch.
I have two questions:

1) the rig comes with 500 Gh/s, 750 Gh/s, 1 Th/s, 1.25 Th/s, 1.5 Th/s, 1.75 Th/s, 2 Th/s Hashing power.
The Upgrade for the rig is 150 GH/s. That does not connect, or iam missing something?

2)
The product detail page states:

"This will add 150 GH/s of nominal and up to 225 GH/s of Turbo mode hashing power to your system. Up to 14 modules per system can be purchased."

can you put 14 modules in a 500 also as in a 2th rig?

thanks

i called them yesterday and they told me that they have changed the design from the upgrade modules from 150 to 250 gh/s. it isnt announced on the page yet, but will be in some days.

and the maximum amounts of upgrade modules in a 500 GH/s Rig is 10 Modules, equals to 1500 GH/s

[stevebrowne]

 500 GH/s + (10 * 250 GH/s) = 3TH/s ?

Are normal cards in the Coin Desk being upped from 200GH/s to 250 GH/s as well? That would certainly help with the upcoming difficulty bumps.

I want to know if you still offer hosting? what is the pricing?

[mangza]

hello i'm order and pay send your email please check and reply me

Whats this about needing two circuits? If in turbo mode it's utilising 3kilowatts, well thats only like having a 3kilowatt heater plugged into the socket... whats the difference?

Damien.

You can't plug a 3kW heater into a standard 110/115/120V 15A/20A circuit.

I admit it isn't very well specified on our product page, but the Rig design uses a single, high performance 3kW power supply unit with a single IEC C19 connector cable to draw up to 16A (at 230V). Hope this clarifies a bit 

If I have a 2TH Rig, how much power consumption draws from the wall? I live in north america which is 110V and 15A breakers, how am I suppose to power the rig as my maximum safety continuous power draw is 1320W considering should not exceed 80% of the circuit breaker's maximum amperage

Use your dryer circuit. Or just have a 220 line wired in. You already have it at the panel.

500 GH/s + (10 * 250 GH/s) = 3TH/s ?

.. would be (very) nice  

.. finally I got my order (3204) with delivery in week 6 confirmed.

[stevebrowne]

I'm order 3062 and they told me week 7 - wasn't happy as when I ordered it said week 6. And a week can make a massive difference.

BitMine - why is my order earlier but delivered later?

The 10 Modules refers to the 150 GH/s. The 250 GH/s Upgrade would be only 6 then. From the Desk they havn't said anything and i havn't ask,

Simple fact, American power supplies at 120 volts have less watts available than European power running at 240 volts.  A 3000 watt single power supply doesn't give you 3000 watts when run in America, Asia, or anywhere else that has 100-120 volt power.  It probably maxes out at 15A x 120 = 1800 watts.

Different companies have solved this problem different ways.  KnC announced that if you run in north america they will scale back the performance - i.e.: you won't have all the power available so they disable some of their hashing chips so the system runs slower...  whereas  Cointerra and Hashfast went the more expensive option and used two (smaller) power supplies so that you can run off two separate circuits to achieve the full power required.  

It'd be much cheaper and easier to just stay with the single 3000 watt single power supply, but when more than half your customers (all of north america and most of asia) won't get 3,000 watts its kind of a bad idea.   That solution only works for European customers.

For those in North America with split-phase 240V into their homes (which I believe is most of them), it's as simple as putting another branch on in the same way you'd wire your stove or clothes dryer. It just means you can't run it on a standard outlet, but you wouldn't want to do that anyway really. Much better to have a dedicated line.

Out of curiosity (since I don't have time to follow the 20 new pages a day on the KnC thread) where did KnC announce that they would scale back performance for North American customers? Do they not just provide PCIe plugs that you have to connect to a power supply you provide?

BitMine - why is my order earlier but delivered later?

BitMine - please can I have an official response? My order number is 142 orders earlier, I have fully paid, and yet it seems I'm getting it a week later. What incentive is there for people to pay when queue position is NOT guaranteed.

If there is no official response, then I think people considering paying up front to get in the delivery queue should be very wary.

[SwissMiner]

.. I will pick it up .. maybe that's the reason?

[stevebrowne]

That shouldn't effect things. If they are making them and giving them to the queue in order, then collection/delivery is irrelevant. It's either the customer or the courier collecting it.

Maybe my order is actually going to come in January, and they just haven't explained it well enough. Official comment would be nice.
