Just put three more gigs of ram in Powermac Dual Core 2.0 late 2005 with bluetooth airport. Instead of reading the memory as PC2 4200, it is reading it as PC2-3200U-288 and PC2-3200U-266? And it still shows up as four gigs total (the correct amount) and says the ram is "OKAY". HUH? Am I hurting the Powermac? Am I getting full speed out of it? Canada Ram, I don't get it!
