Memory Modules
This section describes the memory modules.
4.4.1
Overview of memory modules
l The memory module configuration uses synchronous dynamic random access
memory (SDRAM).
l Memory modules employ error checking and correction (ECC).
l Upgrades of memory modules must be done in sets of four. All memory modules
mounted on a system board must be of the same type.
For memory module expansion, contact a certified service engineer.
Note:
The riser card is an adapter card that is used to efficiently mount memory
modules onto the system board.
