User Tip: Mac Pro and Error Correcting Code RAM Memory
Modules not seen, and modules seen as half their size have failed, and would need to be replaced.
Many Mac-centric vendors offer lifetime replacement warranty.
This additional information , my memory modules did the same only when I upgraded the Operating system there was a fix to reset the memory data that holds the info on what was the correct total. This is not a bad memory module. I will need to reset the data that holds that data , and force the system to reread the data... help...
