System Memory
The system supports x4 or x8, single- or dual-rank fully buffered 667 MT/s (5-
5-5 latency) DDR2 DIMMs in 512 MB, 1 GB, 2 GB, or 4 GB packages.
Four memory risers must be installed at all times. The risers connect to the
main board through x16 PCI Express connectors.
General Memory Module Installation Guidelines
AC power must be removed from the system before servicing the memory
risers.
NOTICE: For proper cooling, each memory riser must be fully populated with
DIMMs or blanks or a combination thereof.
Four memory risers with one DIMM per riser must be installed for the server
to function.
Supported memory riser configurations are as follows:
All DIMMs must be FBD using DDR2 DRAMs (FBD Generation 1).
In all cases, DIMMs must be installed starting with the lowest number slot
in a given channel (i.e., install DIMM1 first).
In non-Mirrored Mode, all DIMMs with the same slot number within a
given branch must match (size, technology, etc.). It is not required to
match DIMMs between different slot numbers.
