  • Four 240-pin Double Data Rate 2 (DDR2) SDRAM Dual Inline Memory Module (DIMM) connectors with gold-plated contacts
  • Support for:
    • Non-ECC, 1.8 V, DDR2 800/667 MHz memory
    • Serial Presence Detect (SPD) memory only
    • Unbuffered, non-registered single- or double-sided DIMMs (except double-sided
    • DIMMs with x16 organization)
  • Memory configurations listed below:
    • Up to 2 GB utilizing 256 Mb technology
    • Up to 4 GB utilizing 512 Mb or 1 Gb technology
    • Up to 8 GB utilizing 1 Gb technology
    • Up to 16 GB utilizing 2 Gb technology
  • A minimum of 512 MB of total memory is required

Supported DIMM configurations

DIMM Type SDRAM Technology Smallest Usable DIMM (one x16 Single-sided DIMM) Largest Usable DIMM (one x8 Double-sided DIMM) Maximum Capacity with 4 Identical x8 Double-sided DIMMS
DDR2 667 512 Mbit 256 MB 1 GB 4 GB
DDR2 667 1 Gbit 512 MB 2 GB 8 GB
DDR2 667 2 Gbit 1 GB 4 GB 16 GB
DDR2 800 512 Mbit 256 MB 1 GB 4 GB
DDR2 800 1 Gbit 512 MB 2 GB 8 GB
DDR2 800 2 Gbit 1 GB 4 GB 16 GB

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.
