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 the dual or single channel memory configurations defined
below:
• Four 240-pin Double Data Rate 2 (DDR2) SDRAM Dual Inline Memory Module
(DIMM) connectors with gold-plated contacts
• Support for:
⎯ Non-ECC, 1.8 V, DDR2 800/667 MHz memory
⎯ Serial Presence Detect (SPD) memory only
⎯ Unbuffered, non-registered single- or double-sided DIMMs (except double-sided
DIMMs with x16 organization)
⎯ Memory configurations listed below:
• Up to 2 GB utilizing 256 Mb technology
• Up to 4 GB utilizing 512 Mb or 1 Gb technology
• Up to 8 GB utilizing 1 Gb technology
• Up tp 16 GB utilizing 2 Gb technology
• A minimum of 512 MB of total memory is required
NOTE
System resources and hardware (such as PCI Express devices) require physical
memory address locations that can reduce available addressable system memory.
This could result in a reduction of as much as 1 GB or more of physical addressable
memory being available to the operating system and applications, depending on the
system configuration and operating system.
