Hi guys, Received my L3+ yesterday and I was so excited Grin

, however, the excitement didn't last for long, seam mu L3+ is now working only on 3 hashing boards Huh

Yesterday I notice that 4th board was having ASIC# 36 instead 72, and today when I powered up the miner only 3 hashing boards are showing.

Now what to do before writing to Bitmain???

I have tried switching on and off the miner and changing the PCI power connectors but no use.

I am using APW3++ on a 240V power grid.

Any advice is appreciated before I raise a ticket with Bitmain

Double check if the PSU is feeding the 4th board with the appropriate power.
If that doesn't help, read issue 6 here:
