Memory (DIMMs)
Depending on the model, Power Mac G5 computers have either four or eight Dual Inline
Memory Module (DIMM) slots arranged in two banks. The slots accept Double-Data-Rate
(DDR) Synchronous Dynamic Random-Access Memory (SDRAM) devices.
The computers ship with a minimum of 256 MB of RAM, provided by a pair of 128 MB
DIMMs installed in slot 1 of each DIMM bank. You can add DIMMs, provided they are
installed in pairs of equal size, one per bank, from the center outward. A diagram marked
on the logic board near the DIMM slots illustrates how the pairs must be installed.
