System memory features
The desktop board supports the dual or single channel memory configurations defined below.

• 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 using DDR2 800 or DDR2 667 DIMMs
• Minimum total system memory: 512 MB
• Non-ECC DIMMs
• Serial presence detect
• DDR2 800 or DDR2 667 MHz SDRAM DIMMs
• DDR2 667 DIMMs with SPD timings of only 5-5-5 (tCL-tRCD-tRP)
• DDR2 800 DIMMs with SPD timings of only 5-5-5 or 6-6-6 (tCL-tRCD-tRP)

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.

Supported DIMM configurations

Tested memory

Computer Memory Test Labs (CMTL*) tests third-party memory for compatibility with Intel boards as requested by memory manufacturers.

The table below lists parts which passed testing during development. These part numbers may not be readily available throughout the product life cycle.
