I can buy 15 chips more from zefir and I'm not sure if it is possible for a 20 chip board to work with only 15 chips placed on it.
Basically Im asking if it can work underpopulated and add later 5 chips more.
I won't do partial assembly, either 10 or 20.
I have a similar question:
Lets say one Chip is damaged - Miner still working ?
The chips, as mentioned before, are calculating in a "row." Which means, that if one chip in a ten chip cascade is dead, the whole row of ten goes down and produces hardware errors.
Depends on the failure mode of the chip.
bang! magic smoke escapes - whole module down, rest of the stack continues to function
chip produces wrong hashes but continues to forward messages - some hw errors in cgminer, hashrate drops by one chip
chip logic completely dead - one row dead from the point of defective chip, hashrate drops by 1 to 10 Chips
My design is spare-no-expense, build for resiliency and reliability. @burnin... I now read that avalon miner were successfully overclocked to 395, stable at 375MH/s or so. From 282MH normal. Now BKKCoins thinks about how to change the layout of the board to meet the higher power supply needed.
Are the bitburner already ready for those high overclocking or would there a change needed because its otherwise not possible. I know overclocking is planned but i believe bkkcoins already had planned it too even though now he needs to revise his board.
My design is able to provide more current to the chips then bkkcoins (2.5A vs 2A per chip).
Therefore i don't see reasons to increase that even more.
Overall Project status:
Done some more work on the Firmware, it now works flawlessly with cgminer.The Prototype will not arrive until mid week due to problems with my manufacturing partner for the protype.
of course, that's not really possible on just air cooling.
