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: • Up to four dual channel 184-pin Double Data Rate (DDR) SDRAM DIMMs connectors with gold-plated contacts. Supported memory configurations are: Memory Speed Processor FSB Memory Speed Outcome DDR400 Intel Pentium 4 processor 800 MHz 400 MHz DDR333 Intel Pentium 4 processor 800 MHz 320 MHz Intel Pentium 4 processor 533 MHz 333 MHz • Support for:  Unbuffered, non-registered single or double-sided DIMMs  Serial Presence Detect (SPD) memory only  Support for Suspend to RAM (STR), S3 ACPI state  ECC and non-ECC RAM (ECC support must be enabled in BIOS)  2.5 V memory • Support for 128 Mb, 256 Mb, and 512 Mb memory technologies for the following memory configurations:  Up to 1.0 GB utilizing 128 Mb technology  Up to 2.0 GB utilizing 256 Mb technology  Up to 4.0 GB utilizing 512 Mb technology 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.
