Main Memory
NOTE
To be fully compliant with all applicable Intel
®
SDRAM memory specification addendums, 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

• Support for:
Unbuffered, non-registered DIMMs
Serial Presence Detect (SPD) memory only
Support for Suspend to RAM (STR), S3 ACPI state
Non-ECC DDR
2.5 V memory
NOTE
System resources, such as PCI, 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.
