HP ProLiant DL580 G5 - For 32 DIMM configurations with the standard shipping 4 GB of memory
Standard Memory
4 GB PC2-5300 Fully Buffered DIMMs (DDR2-667) (4 x 1 GB)
All HP ProLiant DL580 G5 systems come standard with 4 banks of memory sockets spanning 4 memory channels for a total
of 16 DIMM sockets on board memory. The optional DL580 G5 Memory Expansion Boards Option adds an additional 16
DIMM sockets, which brings the Dl580 G5 to a total of 32 DIMM sockets.
Upgrading Memory and Memory Interleaving
To achieve maximum memory performance and flexibility, the HP ProLiant DL580 G5 requires memory to be upgraded in
groups of four identical FBDIMMs populated across the four memory channels. In simple terms, the two FBDIMM locations
at xC and the two xD locations must be populated with four identical part numbered FBDIMMs. Memory population continues
by populating locations xE and xF, then xG and xH. FBDIMM architecture does not allow any gaps in this sequence such
that if locations xE and xF were populated and xC and xD were not, the memory at xE and xF would not be recognized by
the system.
Standard Memory Plus Optional Memory
Up to 228 GB memory is available with the standard memory of 4 GB and the optional installation of 1 GB, 2 GB, 4 GB,
and/or 8 GB PC2-5300 Fully Buffered DIMMs (DDR2-667) in all embedded DIMM sockets as well as the memory expansion
boards slots. One possible configuration is shown below, in which 56 GB is added to the standard 4 GB for a total of 60 GB.
Standard Memory Replaced with Optional Memory
Up to 256 GB of memory is available with the removal of the standard 4 GB of memory and the optional installation of PC2-
5300 Fully Buffered DIMMs in all the embedded slots as well as the memory expansion boards slots.
