System Memory Features
The board has two 240-pin DIMM sockets 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 or DDR2 400 SDRAM DIMMs
Note
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.
