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 dual or single channel memory configurations defined in Table 6.

Memory configuration listed below:

Up to 2.0 GB utilizing 256 Mb technology

Up to 4.0 GB utilizing 512 Mb or 1 Gb technology

NOTE

System resources (such as PCI and PCI Express) 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.
