Product Description

1.5System Memory

The board has one 240-pin DIMM socket and supports the following memory features:

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.

2 GB maximum total system memory

Minimum total system memory: 128 MB

Non-ECC DIMMs

Serial Presence Detect

DDR2 533 MHz or DDR2 400 MHz SDRAM DIMMs (DDR2 800 MHz and DDR2 667 MHz validated to run at 533 MHz only)

NOTE

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.

Table 3 lists the supported DIMM configurations.
