Power Mac G5 (late 2005) memory showing two different speeds
Alright, here's the situation. I have a late 2005, Dual 2,0Ghz, water cooled, model, G5 Power Mac tower. These have 8 memory slots, (1 upper bank of 4 slots and one lower bank of 4 slots located directly above and below each other on the motherboard). The two inside slots (the two slots that are closest together - one from each bank) are labeled slot 1. Then the next two slots (moving outward from the middle) are slots 2, then slots 3, then slots 4. Anyway,according to the Apple specs, the memory should be set up in matching pairs of like modules: i.e. slots one = 2 X 1GB sticks of matching PC4200, slots 2 = 2 matching sticks of PC4200, etc., etc, up to a total of 8 GBs of compatible memory.
I have 8 X 1GB sticks of "matching" Kingston PC4200 memory installed, and it even shows up on the "About This Mac" page as 8 GB. However, if you take this one step further and proceed to the "More Info" page, under the "Hardware" tab, the "memory" info it shows up as 4 sticks of DDR2-PC4200, and 4 sticks of DDR2-PC3200. Ironically, slots 0,1,2,3 indicate as PC-4200 (533Mhz), and slots 4,5,6, & 7 indicate as PC-3200 (400Mhz). Can anyone give me some insight as to why this would be happening? I've also re-arrainged the memory modules, but the memory speed discrepancy stays the same.
Any help would be appreciated!
