Check the RAM bus size on G5 Macs
Authored by: gaboosh on Oct 11, '04 12:44:38PM

I have two questions:

- I haven't installed any extra RAM on my iMac G5 but the ram-architecture-value is 2. Is that right? The hint implies all G5s come with a 128 bit bus

- also - how will i know what the composition is to buy RAM that matches that of the DIMM in my machine already?

You must have both RAM slots filled in order to get a 128 bit bus. It is basically 64 bits per ram slot, and if the chips are close enough in spec the machine 'syncs' them so that it can use them as a single 128 bit wide channel rather then two 64 bit wide channels.
