Black Arrow 28nm 100Ghash Bitcoin ASIC from $0.49/GH/s

[Gator-hex]

Our latest results are 120Ghash while using 150Watts.
 
 

I dunno what everyone is moaning about. Is that 125GH from one chip for 150W?
Compared to the A1 25GH chips that's very good!   Maybe it can be underclocked to get 100GH for 1GH/W?
A:3840 HW:32 = 0.83% Errors which is acceptable but would need to see a longer run.

We have 1GH/W since last year so I don't see what's so special about BA's chips. Price? Availability?

If their production cost per 28nm chip is the same as the A1 it means they'll have a $/GH advantage.

BA will use 75% less chips to create a miner with the same GH as an A1 based miner.

I would buy one but the minimum quantity is 10.  Strange thing is you can buy just one power adapter.

Still waiting... no updates.

If you want just one, I'd wait around here(Bitcointalk).  Once they start shipping, alot of the customers will try to get rid of these guys in Marketplace>Goods>Computer Hardware section of this forum.  Probably be some deals to be had.

Or if you're a glutton for punishment and want to wait like the rest of us suckers, you can order just 1 here:

I think they mentioned May 8th as the next official update, probably sometime mid day for the western customers.

Aside: I have HW showing on the screen from the original prototype testing - so it's also 'in your face' rather than quietly counting HW like all the other ASIC drivers.
(I'll remove that soon)

... and yes that's the old code - I'm testing with current get.

On the BA forums they mention there is an 8% power leak on the current PSU's and sort-of off-handedly said that if you don't like it your order will be delayed until the replacement PSU's are in.  I imagine this is because they are tired and frustrated.  A more official update will hopefully come soon that explains our options and what the final testing results are.

Keep it up BA hope you get .6w per ghs like you said!

Anxiously waiting for 30 X-1!

I think most miners would want to run these off ATX psu's in the long run. Efficiency in mind thats prolly the best option?

I appreciate what BA is doing with both the updates and the compensation package. They could of just left us with the original hosting. And they could of been like BFL and no given anything.

Even though the extra units do not come with PSU's, it's still pretty awesome, money out of their pockets. If you can't afford to buy the PSU's, sell them with out.

[TheMinex]

Overclock pulls down efficiency in both ASIC + PSU. It's obvious that a PSU @ max power is a spreading heater, especially if is rated (10A x 12V & 5A x 5V ) and you ask 150W.

Before work on that inductor, BE SURE that modification dosen't drop efficiency when the system works in SS corner ( this could be possible! ) and amperage is lower.

As I said, people that thinks about overclock haven't realize that mining is not more how many TH we put on the network, but the quality of TH !!

So

• in overclock mode DON'T spend time working on efficienty, focus ONLY in stability and GH/s    
• in underclock mode DON'T spend time working on GH/s , focus ONLY in stability and efficiency

Compromises in corner modes are not allowed, this should be only a natural goal when you run them in TT mode.

You can't do a FERRARI that consume 20 Km/litre, you can't do a FIAT that run 300 km/h ( without die while testing ).

Hi, I see that the power supplies are in the blackarrow store but I have a couple of questions.

1: It shows a shipping and handling fee, can't it be shipped with the main order if I pay with btc?

2: If it can't, can I order 2 psus? (A friend also has an order for an X3)

[y_boonstra]

i would wait if i where you .. dont order your PSU just yet.

[wax7]

uh ... 53 $ for a X-1 Supply     that Hurts...

Is this caper of having to buy a PSU for the X1 separately some sort of a scam to make more profit?

Why was it not mentioned at the time of purchase 6mths ago?

OMG has it been 6 mths already!

No chap you get a psu with your x1 just not with you compensation machines.

It is for their compensation machines. They are offering one free machine for every two you ordered, minus the power supply on the free machine. (if you want that sub-par power supply it is 45+shipping)

The painful optimist in me says, well at least they are giving something away for all the troubles caused.

The cynic in me says that it is total bullshit to compensate people in such a half assed fashion.

I would have rather taken the original 4 month hosting or what ever, something that wouldn't have cost me more money, i don't  have room for all these extra machines.

They had to have realized that to pay for hosting for all the compensation machines that cost was > just giving the customers the machines - power supplies. It seems shady imo. Like when you tell a child to apologize and they do the whole "sorry" really quite and unintelligible until you get on top of them for dickin around.

This  isn't black arrows first rodeo, that is what is most depressing to me, they seemed to have released some lancelot fgpa miners before this debacle without much issue. Maybe it was a couple hundred units compared to what they are looking at today and bit off more than they could chew. I really do not know.

The final thing that is unnerving to me, how many times do these asic companies release  the first batch of machines with no issues? Even after all their testing and what not. I was reading bitmain was having issues with their latest batch of miners, how many get it right the first time with no issues?

You mean all these people bitching in the forums pressuring them to get a product to the market as fast as possible has an negitive effect on quality? Say it isn't so!
