Product Description

1.4 System Memory

The board has one 200-pin DDR2 SO-DIMM socket and supports the following memory

features:

• DDR2 SDRAM SO-DIMMs with gold-plated contacts

• Unbuffered, single-sided or double-sided SO-DIMMs

• 2 GB maximum total system memory

• Minimum total system memory: 256 MB

• Non-ECC SO-DIMMs

• Serial Presence Detect

• DDR2 533 MHz SDRAM SO-DIMMs (DDR2 800 MHz and DDR2 667 MHz validated to

run at 533 MHz only)



NOTE

Due to passively-cooled thermal constraints, system memory must have an operating

temperature rating of 85

The board is designed to be passively cooled in a properly ventilated chassis. Chassis

venting locations are recommended above the system memory area for maximum

heat dissipation effectiveness.

 NOTE

To be fully compliant with all applicable DDR2 SDRAM memory specifications, the

board should be populated with SO-DIMMs that support the Serial Presence Detect

(SPD) data structure. This allows the BIOS to read the SPD data and program the

chipset to accurately configure memory settings for optimum performance. If non-

SPD memory is installed, performance and reliability may be impacted or the

SO-DIMMs may not function under the determined frequency.

Table 3 lists the supported SO-DIMM configurations.
