1.4 System Memory
The board has four DIMM sockets and supports the following memory features:
• 1.8 V and 1.9 V DDR2 SDRAM DIMMs
• Unbuffered, single-sided or double-sided DIMMs with the following restriction:
• 1.8 V and 1.9 V DDR2 SDRAM DIMMs
• Unbuffered, single-sided or double-sided DIMMs with the following restriction:
Double-sided DIMMS with x16 organization are not supported.
• 8 GB maximum total system memory. Refer to Section 2.1.1 on page 47 for information on the
total amount of addressable memory.
• Minimum total system memory: 128 MB
• ECC DIMMs and non-ECC DIMMs
• Serial Presence Detect
• DDR2 667 and 533 MHz SDRAM DIMMs
• ECC DIMMs and non-ECC DIMMs
• Serial Presence Detect
• DDR2 667 and 533 MHz SDRAM DIMMs
NOTES
• Remove the Primary PCI Express x16 (electrical x16 or x8) 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.
