[ANN] Bitfury ASIC sales in EU and Europe

[yohan]

Are the bitfury chips ready? i mean packaged and all?

LOL:)

No offend, but:
1 -  How we can be sure that there are more than a few hundred partially efficient chips (2,3GH/s instead 5Gh/s) cut out of from center test wafer?
2 - Do we have any guarantee that TSMC this year let Bitfurry on their already heavily loaded production lines?
3 - In my opinion all money from preorder go to corrections that must be made ​​to the chip. Than start small quantity test wafers. Unless Bitfury wants to introduce the production of something that had passed with the assumptions for more than 50%.
And if it is so weak performance whether for a few months, these chips will still work? Were the tests performed life-time chip in extremely adverse conditions to determine how quickly degrades structure?
Its very impressive start very risk development so high (55nm) and get working chip. And I am not speaking here against this project, but before invest will see what I'm dealing with.

I'm sure that a lot people will want to see more data on them working and we will do our small part here to move that forward. However it is worth saying that the initial results by people, that have prototypes, have shown a power efficiency miles better than BFL. So even if these chips are only run at 1-2 GH/s per chip it gives a good power figure and a high packing potential. If 5 GH/s is achieved that is a big bonus.

Chips for July delivery are already out there, check the american sales thread an that.

Sorry lol I mean chips that will be soldered onto the August boards
Having been bitten by another ASIC vendor, I wanted to exercise caution.

BTW is  this feature still present in the chip?

Code:

1) the chips have a build in power management / leveling system that we want to use (to save on power and additional pcb components: to power the boards and a string/series of chips with let's say 7.2V directly)  ... this is a crazy idea and we have to check if this works (we must avoid resonance buildup and power voltage osculations) before ordering many boards [[ comments here are very welcome !!! :-) ]]

Yes, this feature is built-in on chip. We are currently testing this feature.

Can you give us some info how is this working, or at least how it should? Do you have some documentation from bitfury that you can share with us?
I'm very curious about this feature but don't see how this can have effect on reducing BOM list. DC/DC is still neede but with less amperage that's obvious, but you need level translators between chips and propably another DC/DC converters to IOVDD. Or I'm missing something?

EDIT:
I think that I've resolved a puzzle Key to this is IOREF pin.

Congratulations on the ASIC guys - I'm glad it worked right first time - the thought of the NRE costs makes me shudder!

It's also very nice to see a project on this continent - I just hope the Euro is still around in October!

1 - We've tested many chips so far (they all come mixed together, no sorting) and have found the yield to be outstanding. We have enough chips in hand to satisfy all orders.
2 - We don't work with TSMC. UMC is our foundry. We already have orders in place for next batch of chips and have no reason to believe that it would be delayed.
3 - We didn't go the MPW route. We went with full mask-set and produced a chip that works just as we expected this to. Hence we had a large engineering run, that was successful and can also be (and is in the process of being) deployed.

Thank you for your professional response.
Did you plan correction on metal layer for improve performance ?
Why we can't buy July chip delivery on EU distribution ? On US page  You can still order for 10 units for July.

When a hashing board is plugged into the masterboard, how much does the socket add to the total height?

From of base the M-CARD to the top of the H-CARD measures 147 mm.

will you accept bitcoins any time soon, and is VAT problem been solved. Do, the shipments, which is going out of EU nhave to be charged with VAT or not. Sorry, if these already been answered somewhere.

[GandalfG]

Any chance for sample chip or buy one for design and testing prototype ?

+1
I am also interested, because i have missed the opportunity and October is too far

[Dexter770221]

Look guys into group buy section. There is at least two group buys, but delivery in October. And still there's no documentation from bitfury

[KNK]

but delivery in October

For October i can just buy directly, but then you add 1 or 2 months for development starting October.
The idea is to test the prototype(s) and make corrections before the volume of chips arived

Exactly. That why I ask for sample or buy immediately.

Quick update:

- H & M Boards are in production (assembly)
- Shipping company arrangements have been made. They offer quick shipping for extra cost. I'll try to add this shipping upgrade option on site somehow.
- Got some test boards for testing the chain set-up:

EDIT: Just to clarify – this chaining is a new feature that will help us build more competitive products, this has nothing to do with current board functionality.

Hi punin,

When you are done testing the 'string theory',
I can draw you a board if you like:)

Hi punin,

on the view order page (http://www.bitfurystrikesback.com/my-account/view-order/) only the 10 recent orders are listed ... If you made more then 10 orders you can't check the first ones anymore ...

anyway to fix this?

Thx.

Hi guys,

I just got back and noticed that bitfury 25GH Miner Starter Kit has changed their delivery from August to October!
Ofcourse, I placed a support ticket about this.

Anybody else ordered a starter kit?
Any idea when we will get our order, August or October?

TIA

I guess that only means that they have sold out August. I have an order in and am expecting it in August, cant find any contradicting info anywhere.
