Clearance: We are now selling under our manufacturing price the remaining Bitfury boards that we have in stock:

http://www.blackarrowsoftware.com/store/bitfury/





Black Arrow has just designed and manufactured a Bitcoin mining solution based on 55nm Bitfury ASICs

These products are in stock and available for immediate dispatch. Interested customers can place orders here: http://www.blackarrowsoftware.com/store/bitfury/

We are offering:

1. 40Ghash individual boards that can be chain connected and have the flexibility to put as much or as little space the customer needs in order to offer the perfect thermal solution. In order to use these boards the customer needs to purchase a single Bitfury Controller and a Raspberry PI.

2. 160 Ghash mining solution that includes 4 x Boards with 16 Bitfury ASICs + Bitfury Controller + Raspberry PI + everything else the customer needs to start mining out of the box (except an ATX power supply that the customer can purchase from the local store).  For a one-time fee we will host your boards for 6 months. This way our customer can start hashing the next day.

3. All-inclusive Bitfury Cloud Hashing. No shipping & no electricity to pay and no head-aches.


We manufacture Bitcoin ASICs and Bitcoin mining equipment.

We do not rate our boards on "maximum performance".  We rate the boards on normal and stable usage that we have tested and deemed to be reliable.
Bitfury ASICs will reach the same performance on all boards as long as the cooling and power is adequate.

In our solution we have provided the overclocking capability for enthusiasts:
- 80A of power
- Heatsinks + 2 Fans
- Flexible cables in order to provide required space for cooling

We do not guarantee higher performance nor will replace burned ASICs. However, we do offer warranty for our boards (except the ASICs).
These ASICs are made by other company and apart from guaranteeing that they work when we ship them we cannot provide any other guarantee. The manufacturer of these ASICs does not offer warranty; they do not even test them.

Note that some ASICs will run faster, some will run slower; the manufacturer of these ASICs has not sorted them by performance.

If our customer wants to be sure that is offered the highest quality service, we suggest that they purchase our mining solution that uses our own ASICs sure for which we can provide complete warranty and full customer support.

Yeah,

144 GH/s should go for 9 or 10 BTCs to have any chance of reaching break-even.

I applaud anyone who has equipment in stock and ready to ship.  Not asking for pre-orders to fund their production.
For most it does not make economic sense at your prices.  But way to go!

The pattern is avoiding spam like your post.

@blackarrow
great offer guys! But the price is horrible and not really competitive compared to others.
BFSB will soon also sell inhand boards at cheaper prices i think.

cheers

This is irrelevant to consumer law. You're selling a product including the chips, and so you're responsible for them.

The only pattern I see here is that this unit is going to ship four months from now after HF, Cointerra and BitMine which is going to deliver 2 TH units at least two months before them (if all goes well) and in the meanwhile KnC and BitFury could deliver (OR increase their mining operations by) petahashes like there is no tomorrow.

Avalons were sold in October 2012 and delivering started at the end of last February, but they were priced at 1500 USD.

So, at 2000-2500 USD I'd probably buy a few edit: prosperos right now, but not at 4500 USD.

BTW, when does Chinese New Year happen  in 2014?

ps. Sorry blackarrow if I'm sounding rude, I appreciate that you're trying to sell on stock items, sadly it is not enough anymore, too many ASIC vendors right now.

Are the boards overclockable via software? Or is a physical change like changing a resistor required?

They are overclock-able through software. However, the user cannot change the voltage which is set at 0.835v. To change the voltage you would need to change some resistors.

We have managed to get stable 40Ghash on these boards, therefore the 144Ghash offer is now 160Ghash.
