I am saying that it should still show the board unless it is really bad. I have 1 machine that has some chips out, but it still shows in the config screen. Do your bad boards not show on the config screen at all?
Yes I have boards that do not even show up on the miner status screen. For example it will say Chain 6, Chain 7 but no Chain 8
Wow. I have never seen this. I started buying from them in the s3 era too. Even swapping the ribbons you still never see the card at all? I understand you may swap and only see 2 again, but are you sure its the same 2 cards? If so, I have to say that's a dead ass board and a problem that luckily I have never seen.
