1..1 Overview

The motherboard comes with four 184-pin Double Data Rate (DDR) Dual

Inline Memory Module (DIMM) sockets.
The following figure illustrates the location of the sockets:

• Due to chipset resource allocation limitation in Windows XP 3-bit

operating system, the system may detect less than 3 GB of system

memory when you installed four 1 GB DDR memory modules.

• When using one DDR DIMM module, insert it into slot DIMM_B1 only.
• When using two DDR DIMM modules, insert them into DIMM_A1 and

DIMM_B1 slots.

• Due to CPU limitation, DIMM modules with 18Mb memory chips

or double-sided x16 memory chips are not supported on this

motherboard.

• Always install DIMMs with the same CAS latency. For optimum

compatibility, we recommend that you obtain memory modules from

the same vendor. Refer to the DDR400 Qualified Vendors List on the

next page for details.

1.. Memory configurations

You may install 18 MB, 56 MB, 51 MB, and 1 GB unbuffered ECC or

non-ECC DDR DIMMs into the DIMM sockets using the memory configuration

in this section.
