Note: Do not forget to connect the CPU fan connector! Hardware monitoring errors
can occur if you fail to plug this connector.
System Memory
The board has four DIMM sockets and support the following memory features:
• 1.8 V DDR2 SDRAM DIMMs with gold-plated contacts
• Unbuffered, single-sided or double-sided DIMMs with the following restriction:
o Double-sided DIMMS with x16 organisation are not supported.
• 4 GB maximum total system memory total amount of addressable memory.
• Minimum total system memory: 128 MB
• Non-ECC DIMMs
• Serial Presence Detect
• DDR2 400 MHz/ DDR2 533 MHz and DDR2 667 SDRAM DIMMs
Note:
• 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 DDR2 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.
The following table lists the supported DIMM configurations.
