Memory (FB-DIMMs) and
Memory Riser Cards
The Mac Pro computer has two memory riser cards with a total of 8 memory slots. On each card,
the slots are arranged as two banks of two slots each. The computer comes with a minimum of
1 GB of memory, installed as a pair of 512 MB fully buered, dual inline memory modules (FB-
DIMMs) in two of the DIMM slots. Additional DIMMs can be installed in the open DIMM slots, as
illustrated below.
Note: DIMMs must be installed in pairs of equal size from the same vendor. In the illustration
below, DIMMs in one colored pair do not need to match DIMMs in a dierent colored pair.
