Time to answer some questions!Can you try to run it with two PCIe connectors per board? It would be interesting to see if it needs all three.
The miner won't operate with two PCI-e connectors per board, according to Bitmain. See this image:

I know it says that but what happens if connect only two? Does not power up at all? 1/3 of chips on the board don't work?
Thanks for the pictures, looks great.
