Upgrading DRAM

This section describes how to upgrade dynamic random-access memory (DRAM) on the system board.

You might need to upgrade DRAM for the following reasons:

• You have upgraded to a new Cisco IOS software feature set or release.

• You are using very large routing tables or many protocols (for example, when the router is set up as

part of both a large external network and your internal network).
