System Memory Upgrade
This document provides instructions for upgrading the Rambus inline memory
modules (RIMMs) on the Dell Precision WorkStation 420.
NOTES: Dell recommends that only a technically knowledgeable person perform this
procedure.
Dell recommends that you read the entire procedure before you begin. You must also
be familiar with removing the system cover and locating the RIMMs.
Dell recommends that you print the contents of the system User's Guide for
referencing important information that may not be available during critical procedures.
This document is available on your Dell Precision ResourceCD and can also be
accessed from the User's Guides icon on your desktop if you have not reinstalled the
operating system.

RIMMs. Otherwise, the existing BIOS may not recognize the new RIMMs, and the
system will not operate.
