DIMMs
Xserve G5 has eight Dual Inline Memory Module (DIMM) slots arranged in two banks. The
slots accept Double-Data-Rate (DDR) Synchronous Dynamic Random-Access Memory

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. Numbers marked
on the logic board next to the DIMM slots illustrate how the pairs must be installed.
In addition, DIMMs must fit these specifications:
• PC3200 error-correcting DDR SDRAM, also known as DDR-400
• 2.5 volt
• 64-bit wide, 184-pin module
