Hello, I have a Power Mac G5 (1.1) dual 2 GHz and wanted to add more RAM Memory. Currently I have 4x 256MB and 2x 1G DDR2-4200-444 on 8 slots, 2 being vacant so I wanted to add 2G x2. Tried two types Kingston and OCZ capable up to 667MHz. when I checked the info it's showing only PC2-3200-288? The rest of my existing RAMs were PC2-4200-444. I removed all the old RAMs and with just the 2 new 2Gs and it's still showing speed of PC2-3200U-288. Could it be because these new RAMs varies in 3 speed? Any input is appreciated.
