1.5 System Memory
The board has four DIMM sockets and support the following memory features:
• 1.8 V (only) DDR2 SDRAM DIMMs with gold-plated contacts.
• 1.8 V (only) DDR2 SDRAM DIMMs with gold-plated contacts.
• Unbuffered, single-sided or double-sided DIMMs with the following restriction:
Double-sided DIMMS with x16 organization are not supported.
• 4 GB maximum total system memory. Refer to Section 2.2.1 on page 49 for information on
the total amount of addressable memory.
• Minimum total system memory: 128 MB.
• Non-ECC DIMMs.
• Serial Presence Detect.
• DDR2 533 MHz or DDR2 400 MHz SDRAM DIMMs.
✏
NOTES
• Remove the PCI Express x16 video card before installing or upgrading memory to avoid
interference with the memory retention mechanism.
• To be fully compliant with all applicable DDR SDRAM memory specifications, the board
should be populated with DIMMs that support the Serial Presence Detect (SPD) data
structure. This allows the BIOS to read the SPD data and program the chipset to accurately
configure memory settings for optimum performance. If non-SPD memory is installed, the
BIOS will attempt to correctly configure the memory settings, but performance and reliability
may be impacted or the DIMMs may not function under the determined frequency.
