Title: Black Arrow 40Gghash boards based on Bitfury 55nm ASICs
Post by: blackarrow on October 29, 2013, 06:55:28 PM
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 (http://www.blackarrowsoftware.com) 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 (http://www.blackarrowsoftware.com/store/40ghash-16x-bitfury-hashing-board.html) 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 (http://www.blackarrowsoftware.com/store/bitfury-controller.html) and a Raspberry PI (http://www.element14.com).

2. 160 Ghash mining solution (http://www.blackarrowsoftware.com/store/160ghash-mining-solution.html) 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 (http://www.blackarrowsoftware.com/store/bitfury-cloud-hashing.html). No shipping & no electricity to pay and no head-aches.

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!

@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.

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?

spiccioli

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.

There is a product on your store wich might lead people in error. Product is Prospero X-1, on its page you say, "Availability: In Stock", potential customer is tempted to order, but if you look carefully under the "Add to cart" button, you see " This product will be available on 24/02/2014" ; so clearly, your product aint in stock.

We've encountered this problem before. Until now we did a pretty crude hack to get the store to display Pre-order but this hack won't work as we have products in stock.

We'll try to fix it.

We are happy to announce that with the new Bitfury Controller that we've just finished we've tested 24 boards yielding 960Ghash with just one Raspberry PI.

We think that we can run 32 boards but we have not tested this yet.

Post by: Bicknellski on November 05, 2013, 03:17:54 AM
... psst...

I think people think they are overpriced.

---------------

Questions for the community:

What ASIC hardware currently is not "overpriced"?
What price is not "overpriced" for these units?
What is the cost of production for these units?
What is a reasonable markup for a fabricator on units?
What is the cost of the chip?
What is the BOM cost?
What is the fabrication cost?
Should their be a "premium" on miners available today versus pre-orders?
Should miners be sold in USD or BTC?

--------------

Maybe a dialogue on these questions might work to inform the community about what the manufacturers can realistically provide versus meeting the realistic expectations of the consumer.

A: None

If you're looking to protect the network, buy an ASIC. If you're looking to make money, just buy BTC and hold.

Even the ASICs I bought that I thought would be profitable by using a smart bitcoin mining calculator were unprofitable. And now, none of them look like they will be profitable on smart bitcoin mining calculators.. so it may be even worse than the first round. I think a lot of people are going to lose a lot of money.

I hate to sound like eve, but I am done investing in Bitcoin mining equipment... it is simply a scam.

I don't think this is a "scam" and I would argue that "scam" is an unfair characterization of BA, KnC and Bitmine and those who are still building miners like BlueFury, RedFury, Marto, Bobsag3 and the guys who fix the Klondike and got them running.

Scam should be applied to BFL, Avalon etc. given what they are currently doing in terms of refunds and what they have done in the past with failure to ship on time. Price gouger would be the appropriate moniker for Asicminer products. Seems to me if the market for miners dries up and we are left with BFL, Avalon and ASICminer when things level out again in terms of difficulty we are going to see those companies fleece the sheep again. I would hope there is a maturing in the market place so that there is some competition in the future and companies like BFL, ASICminer and Avalon just disappear.

I agree that buying BTC or even some Altcoins is the better option but you know you can't just lump everyone in the same pile. Miners will continue to be produced I think even if the "ROI" isn't there as the tech being pushed is more efficient and that maybe of interest to established miners who would like to cut down on costs and position themselves better by replacing ageing units. Also there are still a large number of hobbyists keen on learning about mining, getting new toys even if it doesn't "ROI" will hopefully push some rigs out the door over the next 12 months.

What is V1 optimal?

cgminer does 39.5GH/s without any adjustment at all.

I've simply not had the time to tune it to allow using anything but the default settings, and on default I get ~39.5GH/s
I also use Arch not Raspbian
