It was showing 3 boards mate, rebooting via logging in done nothing and still showed 3 boards, it ONLY went to 2 boards when i physically unplugged it ?
I have checked the ribbon cables between controller and board and is fine.
Also my other faulty miners only show 2 boards, they are the new type self adjusting fan speedd/frequency as well...So it is the norm for me.
I have also swapped pcie-e connections from good board and even new psu's.
NOT worth sending back as they are 11.5Th models and run at 9.6Th !!!
Just hate losing hash power when i have access to free leccy !
Cheers Mate
It is only showing 2 boards bro, something is going on with the controller I'm telling you. Try the ribbon cables 1 by 1 on each card till you find the bad cable or board. If you will notice when you add the 2 it shows together with the amount of each one, it will be full speed. 1 board is not showing at all.
Trust me I have over 20 s9'2 and they have different versions of firmware yet all of them show all 3 boards.
