First prototype of Bitfury S-HASH board is hashing:


Features:
  • 16 Bitfury ASIC capacity
  • Adjustable (through 0805 SMT resistor) voltage regulator between 0.7 and 0.9V
  • Core voltage regulator has 50A capacity, so chips can be overclocked.
  • On-board ARM Cortex M3 processor with standard RJ-45 100 Mbps Ethernet port.
  • Built-in mining software can operate stand-alone. No PC or Raspberry PI needed, just an internet connection.
  • TCP/IP stack with DHCP and DNS support. Just fill in pool server name, port number, username and password.
  • Support for Stratum and backup mining pools.
  • Built-in small webserver for chip status/speed reports.
  • PCB temperature sensor, could be used for automatic shutdown when temperature gets too high.

If you don't have the budget for a large number of chips, overclocking is the best option, as it will get you 40GH/sec out of a card (probably more with better cooling), instead of 25GH for a standard H-CARD for the same 16 chips. At 40GH/sec, the card uses about 35 Watts, running off a standard 12V DC supply.



Beautiful work cscape.

Is there any chance of retrofitting current H model boards for a little overclocking?  I have no fear of a solder iron.  Smiley

Hooray for non-equilibrium thermodynamics!
Nice stuff indeed, congrats! When and where will we be able to order? Bitfurystrikesback.com?

very nice. what kind of cooling are you using to get 40GH/s? what are your plans for this board?

Is it still possible to obtain / purchase of test chips?

Someone can give me dimensions of thermal pad? And what material is used (copper?).

punin do you have any information when you will be able to send chips to the testers that have not received chips yet.

Hey guys, just made a first custom housing design for bitfury miners, take a look here:

Made a few changes to Legkodymov's fork to provide initial support for multiple chips / chaining.  My fork is located at: https://github.com/OrphanedGland/cgminer.

It looks like I will need to maintain work/owork for each chip in driver-bitfury.c, which is not done yet.  Assistance is welcomed Smiley

Nice, thanks for the link, running of a Pi is a good idea too.

Will it be possible to overclock the H-boards that are being sold by several of the Bitfury distributors?

No idea, you'll need to ask whoever designed it. We're just an alpha tester and not directly related to any of the current distributors or suppliers of the H-Board.

hi

why it s running at 1.2 giga?

it was not supposed to run at 2.7?


We're still waiting on our heatsinks (had to get a custom sink since the SMA connectors poke out the bottom of the board a bit, couldn't just toss it ontop of any 'ole sink). Nigel also didn't have a FLIR camera at that location to be sure the chip didn't over heat while running without a heatsink. He was playing it safe. We should have more information soon.

The clock of the chip is determined by the clock setting and what the chip is capable of running at on a specific voltage. We have a break down of a previous test at the bottom of the following URL. All of those tests were conducted with no heat sink.
