Memory overview

This server supports up to four memory boards. Each memory board contains four DIMM slots for a total
of 16 DIMM slots in the server. Memory can be expanded by installing PC2-3200R Registered DDR2
DRAM DIMMs.
The server supports a host of AMP options to optimize server availability:
•
Advanced ECC
•
Online spare memory (on page 69)
•
Hot-plug mirrored memory (dual- and quad-board)
•
Hot-plug RAID memory (on page 71)
Hot-plug operations can be hot-add or hot-replace. Hot-add makes additional memory resources available
to the operating system. Hot-replace allows failed or degraded DIMMs to be replaced while the server is
running.
The maximum supported total memory for this server is 64 GB using four memory boards. The maximum
supported memory per memory board is 16 GB using four 4-GB DIMMs.
For an overview of single- and dual-rank DIMMs, refer to "Single- and dual-rank DIMMs (on page 68)."
For DIMM slot locations and bank assignments, refer to "DIMM slot locations (on page 19)."

General memory configuration requirements

The following configuration requirements apply regardless of the AMP mode.
•
DIMMs must be installed in pairs.
•
DIMM pairs within a memory bank must contain DIMMs with the same part number.
•
Always populate the DIMMs in sequential order per bank: Bank A and then Bank B.
•
Always populate the memory boards in sequential order: Board 1, Board 2, Board 3, and Board 4.
Any deviation from this requirement results in the server defaulting to Advanced ECC
ECC memory" on page 68) on the next reboot.
