1.7 System memory
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.
