Did I understand correct only 1.2 Gh/s?!? Is this due to the voltage/clock not being run at the planned values to achieve 1.5625 Gh/s per chip (25 Gh/s / 16). 1.2 Gh/s makes the 25 Gh/s starter kits just 19.X Gh/s isn't it.? |

Check out his other blog, https://bitcentury.io/blog/initial-testing-of-bitfury-asicThey got it up to 2.4 GH/s at 0.8v 2.185a. Would just need proper cooling and these could be pushing close to 40 Gh/s. |

Anyone know the dimensions of the H and M boards? Going to research some case or rack-mounting options.
Thanks.

Tell us about your rack ideas   |

Based upon those dimensions, I calculate the following at the "minimum occupied" space by a full 400GH/s setup.
M-board (the width): 368mm (assuming about a 5mm hang over from the end of the mounting holes there, which measurement for are not given)
H-board (the height and depth): 110 x 134mm (again assuming a little bit of hang over from the listed hole dimensions)
3U's of rack height is 44.45 x 3 = 133.35mm
So we could mount a 400GH/s unit in an empty 3U chassis with the following configuration:
INTAKE --> | FANS --> H-boards-MBoard --> Exhaust
That should give the best cooling using 3U standard Datacenter chassis, with cold air coming in over the hashing chips first, before it hits the H-board.
Thoughts?
EDIT: had M/H boards reversed

I know for sure the month of delivery is different.
That's the only difference. |

Some people wait for starter kits first then buy H-board later but gone up 50 more and now 500us. |

I think 100 asic chips for 1300us for July delivery and for Oct delivery 250us. |
