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:

• 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.
