[ANN] Bitfury ASIC sales in EU and Europe

[jlsminingcorp]

Don't have coins to buy a whole one. Amazed nobody started decent groupbuy.

Not sure if you call it decent , but you'd be welcome to join us (https://bitcointalk.org/index.php?topic=252534.0) - not VAT free though I'm afraid. Darkfriend77 (https://bitcointalk.org/index.php?topic=254157.0) and coinhoarder (https://bitcointalk.org/index.php?topic=268280.0) have mixed supplier GBs including bitfury hardware that may also be of interest.

Thanks, jlsminingcorp. I have to read all these multipage threads tomorrow and make up my mind.

Edit:
Coinhoarder thread: "Please send your investment to: -redacted- No longer accepting investments." Ah, I missed that one. Two threads to go.

punin im looking to pay via bank but my bank requires your bank address can you give it to me please?

?

Same question, we've sold BTC instead of paying through Bitpay (the Bitpay rate was ~10% below the MtGox rate) as bank transfers seem supported. Given pbigmoon message I'm not sure where we'd find the SWIFT code and IBAN to do the transfer when the € hit our bank account. Is it integrated in the webshop (displayed with a reference to attach to the transfer) / handled manually / ... ?

after you make the order it shows


    Account Name
    Bank Name
    IBAN
    BIC

its just my bank requires that i enter the bank address which it doesn't give

use order number as reference

Ah, missed that, sorry. There was a bitfury GB hosted by pajak666 too, but this closed a while back.

Most "fanless" PSU rely on the airflow forced by the case fan(s). They are overpriced and will die soon in true fanless environment.

Correct ... unless you use a 1500 Watt PSU for a 400 Watt job (and it is not sitting near window with direct sun light).

500 GH/s.

ATTENTION!!! PLEASE PERFORM OPTICAL INSPECTION OF BOARDS YOU'VE RECEIVED!! THERE HAVE BEEN REPORTS OF SOLDERING ERRORS! I WILL SEND INSTRUCTIONS TO DO THIS SHORTLY!!

I have a 4 year old Fanless Seasonic that has been running in a case with zero air flow.  I used to write PSU reviews for XCPUs, and many of the high-end fanless PSUs do not need any substantial air flow, even at 75-80% of max load, for years on end.

Your assumption, simply put, is wrong.

No, this is different. There can be shorted pins on underside of M-board. The H-board capacitors are ok and joined pins on chip don't matter except if they are IO pins. I will post some photos very soon to help you identify problems!

Ok then, I stand corrected on that. Good to know.

My assumption was based on older fanless Thermaltake PSU, that was very pricey and died after a few months. The warranty was voided because in the manual there was a requirement that there must be an intake fan in the PC case.

Hashing at a steady 41-42 GH/s.
Now helping to find the last blocks at 65mil diff. Will be much higher soon...

An odd thing that happened: When I connected to BTCGuild and went off to work, the hashrate kept dropping until it reached about 20GH/s... maybe I should have restarted the miner after I set the minimum difficulty to 32 for my worker?
Any way, it's steady after a restart now! I wonder if the order of the boards makes a big difference? When I get some other H-Boards in October, should these slower boards go in the slots in the back?

And Punin, I would like to thank you personally for this sexy device Ordered 25GH/s, got 41GH/s. Thats 164% of what I wanted 

[tccd]

I received my starter kit today. I am running it now (about 41 GH/s) without any fan and the ambient temperature is 24C. Do I have to be concerned or running without any fans with a kit with just 2 H-boards is not a problem?

[gingernuts]

Congratulations on getting all the August orders shipped out guys! 

Now that they are all out of the way, could you please tell me what the lead-time is on the bare chips, and will they be available at a price that makes rolling your own boards a reasonable option compared to just buying the H-boards?

Cheers.

Not a problem with the core voltage that is on your boards. Our chip has been proven to hash even at such extreme temperatures that the solder melted Then it started floating and shorted itself, ending hashing Some of our users are actually reporting decreased hashrates after adding fans. YMMV.

[Isokivi]

I can confirm that the boards really do not seem to like cooling. Im even partially blocking any natural air-movement to them and have achieved the best results seen thus far:
speed": 1766, "noncerate": 50.967, "noncerateperchip":1.593, "hashrate":52.690, "good":3560, "errors":148, "spi-errors":2, "miso-errors":0, "jobs":375, "record":50.924

Which translates in to a constant average hashrate of just under 49,5 Gh/s.

[edit]
In should propably in all fairness also say that achieving this also required turning the autotune off and hand tuning the chips for about two working days... the problem with 5 minute samples is that you do need a lot of them to make the right adjustments.
