punin, any news with new / old cards ?

punin, any news with new / old cards ? 

any news?

we need hashing power.

[badalien]

i want to buy some h-cards, when there are available again, Punin give us info.

[tarmi]

I find the lack of support and more H card 1.2 to buy disturbing.

[rupy]

I think they have new hardware coming up, and they know that there is some (non ROI focused) BTC chasing it since the price increase, so they probably have to scale things up a bit and make sure they test things properly so it doesn't end up like the disaster BFL&co are.

What are your experiences on how the October 400 GH/s units respond to temperature changes? Is lower generally better? Is there some kind of sweet-spot? Or does the temperature not matter as long as it's below critical (chips melting )?

[baloo_kiev]

How long does it take for the chips to ship? Will I receive a tracking number?

In may cases for OCed chips (0.86V) best start with little airflow after PCB get 40-45 ^oC start cooling.  DC-DC conveter need cooling from the start. It is difficult to reconcile these two requirements. I use independent heatsink for DC-DC conv that take 30% available PCB space.
If I start with very cold air, I must restart miner few times for get stable 41-42Gh from board. I think about write little application that run from crontab and will adjust the fan speed depending on the chip  temperature.

In summary, from my experiment  best result I get when PCB stay in  40-45 ^oC, they like to be warm but not hot.

DHL called me today and arranged delivery for tomorrow. I guess they have my chips because I'm not waiting for anything else delivered by DHL. Next time I'd prefer receiving tracking number from BFSB before delivery.

Thats strange.. Punin personally sent me my tracking numbers for my chips on ordering.

Question to PCB designers:

I submitted a Bitfury h board for fab and got the following message

Code:

1. It appears that your design has 9-12 mil holes, we require a minimum of 15mil drill with drill+10 pads for vias and drill+15 pads for mounting holes.
2. We found over 5 thousand isntances of 5.8-5.9 mil spacing, we require a minimum of 6mil spacing and no less than 6.

Can someone comment if these changes can be easily done in Eagle?

Maybe problem is C-Scape use metric on design ?
My PCB producer accept without any comment h-board design. I have a meeting in fab tomorrow afternoon (Thursday).  From the initial quotation conclude that the cost of production and assembly will be attractive.
The main problem is the availability and price of Bitfury chips. No reel in EU shop

are you planning to sell H boards to the public?

That's excellent. I am only building 2 boards to practice. That is why they want relaxed specifications. Would surely want to buy boards from you if they would be available quickly

Received the chips. That was really quick, excellent service! But still no tracking number was given.

Check this out:



Left - chip from Bitfurystrikesback, right - chip from Bitbonanza. What other markings do you guys have? I should start collecting them

Yes, I want sell part of production.

I wonder what is the demand here. If there is anyone willing buy please post how many boards.
Price cards because of the cost of purchase of chips will definitely not be less than:

320$ - 16x Bitfury chip
35$  -  rest part
  -  PCB/assembly

Tomorrow after I get final quotation for PCB and assembly post complete price.

You order single chip or reel ?

I would be interested in up to 16 h-boards. But the price is a bit high, around $299 would be a much nicer number.

[Foofighter]

also interested in 1-5 hboards.

depending on final price.
