Was given a dead G5 Dual Core Power Mac with 8 slots holding 8 memory modules. Do NOT know what each one is. Two modules are labeled 1GB each, but the rest do not say what they are. Would possibly like to use these in G5 Single Core 1.6 Power Mac, which could take 4 GB to max out. Labels on Memory Modules have bar codes and numbers. Two of the modules say PC3200, with bar code and numbers. HOW do I identify what each module is? Will a PC3200 work in the PM G5 1.6?
