Installing and Removing Memory

CAUTION
To be fully compliant with all applicable Intel SDRAM memory specifications, the boards require
DIMMs that support the Serial Presence Detect (SPD) data structure.
You can access the PC Serial Presence Detect Specification at:
http://www.intel.com/technology/memory/pcsdram/spec/
The boards have two 184-pin DIMM sockets arranged as banks 1 and 0, as shown in Figure 12. If
installing a single DIMM, install it in bank 0. If installing two DIMMs, install them in banks 0
and 1.

DIMM Installation Guidelines

All memory components and DIMMs used with the boards must comply with the PC SDRAM
specifications. These include the following:
•
PC SDRAM Specification (memory component specific)
•
PC SDRAM DIMM SPD Specification
•
PC SDRAM Unbuffered DIMM Specification
•

Installing DIMMs

CAUTION
Install memory in the DIMM sockets prior to installing the AGP video card to avoid interference
with the memory retention mechanism.
To install DIMMs, follow these steps:
1. Observe the precautions in "Before You Begin" on page 23.
2. Turn off all peripheral devices connected to the computer. Turn off the computer and
disconnect the ac power cord.
3. Remove the computer's cover and locate the DIMM sockets (see Figure 12).
4. Remove the AGP video card (if it interferes with the DIMM clips being easily opened and
closed).
