No Comeback For FPGA Boards, Blackminer F1

[numismatist]

There is a modern design of old technologie available, these casings are best industry practice.



Overall containing a dozen huge FPGA (not ASIC!) chips, 6 on a single Hash board.
Just from my (outdated) experience running ZTEX boards, those who closely assembled a Cairnsmore1 device:

They did not last for long, old devices usually featured 3 of 4 chips remaining and 1 dead chip which was not replaceable. Placing 6 on each Hash board requires perfect cooling conditions.

So, any ideas how to improve this design? Bigger heatsinks? Additional lamination on the boards?

Moar boards. For easier replacement of single failed chips. So you don't have to accept beeing 2 of 6 in a defunct state because 4 still left running. There are 12 inside, the material costs for placing them on 6 Hash boards instead of merely 2 are negligible.

The older designs had been the better ones. Except installation layouts, sometimes (depicted) (not mine)
