Desktop Board Features Main Memory NOTE To be fully compliant with all applicable Intel® SDRAM memory specifications, the board should be populated with DIMMs that support the Serial Presence Detect (SPD) data structure. If your memory modules do not support SPD, you will see a notification to this effect on the screen at power up. The BIOS will attempt to configure the memory controller for normal operation. The desktop board supports system memory as defined below: • Dual channel and up to four 184-pin Double Data Rate (DDR) SDRAM Dual Inline Memory Module (DIMMs) connectors with gold-plated contacts. • Supported memory configurations are: Memory Speed Processor Front Side Bus Frequency Memory Speed Outcome DDR400 Pentium 4 processor 800 MHz 400 MHz DDR333 Pentium 4 processor 800 MHz 320 MHz Pentium 4 processor 533 MHz 333 MHz Pentium 4 processor or Celeron processor 400 MHz 266 MHz DDR266 Pentium 4 processor 533 MHz or 400 MHz 266 MHz Celeron processor 400 MHz 266 MHz • Support for:  Unbuffered, non-registered DIMMs  Serial Presence Detect (SPD) memory only  Support for Suspend to RAM (STR), S3 ACPI state  Non-ECC DDR (ECC memory will run in non-ECC mode)  2.5 V memory NOTE System resources (such as PCI and AGP) require physical memory address locations that reduce available memory addresses above 3 GB. This may result in less than 4 GB of memory being available to the operating system and applications.
