Hi, I'm running a Mac Pro 1.1, recently upgraded to 10gb memory and running 64bit Win7 ultimate. However windows only detects 6gb (OSx detects all 10gb). However, Hw detection software detects that all 10 are installed. Configuration is: Bay A 512mb 512mb 512mb 512mb Bay B 2gb 2gb 2gb 2gb I replaced the two last 512mb from "Bay A" with the last 2 in "Bay B". This ended up showing 5GB in windows. Can anyone help me?
