Dear Friends:


I have a Mac Pro 3,1 with 16GB of RAM in 4 modules of 4GB each.


Two of them are plare placed at the top tray and the other two at the bottom tray.


But now the system information only recognizes 12 GB of RAM in 4 modules (4 + 4 and 2 + 2).


I have checked the RAM modules, and I have interchanged the trays. Nothing happens.




The placement of the RAM modules is correct, following the official guide:


Thank you very much for your help.
