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 ("Advanced ECC memory" on page 64)
•
Online spare memory (on page 66)
•
Hot-plug mirrored memory (dual- and quad-board) ("Hot-plug mirrored
memory" on page 67)
•
Hot-plug RAID memory
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."
For DIMM slot locations and bank assignments, refer to "DIMM Slot Locations
(on page 108)."

General memory configuration requirements

The following configuration requirements apply regardless of the AMP mode.
•
DIMMs must be installed in pairs.
•
DIMM pairs in a memory bank must contain identical DIMMs.
•
Always populate the DIMMs in sequential order per bank: Bank A and then
Bank B.
