• Memory
The board has four DIMM sockets and supports the following memory features:
•
1.8 V (only) DDR2 SDRAM DIMMs with gold-plated contacts
•
Unbuffered, single-sided or double-sided DIMMs with the following restriction:
Double-sided DIMMS with x16 organization are not supported.
•
8 GB maximum total system memory using DDR2 667 or DDR2 533 DIMMs;
•
Minimum total system memory: 512 MB
•
Non-ECC DIMMs
•
Serial Presence Detect
•
DDR2 533 and DDR2 667 MHz SDRAM DIMMs
NOTE:
A minimum of 512 MB of system memory is required to fully enable
both the onboard graphics and the manageability engine.
NOTE:
To be fully compliant with all applicable DDR SDRAM memory specifications, the
board should be populated with DIMMs that support the Serial Presence Detect (SPD) data
structure. This enables 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, the
BIOS will attempt to correctly configure the memory settings, but performance and reliability
may be impacted or the DIMMs may not function under the determined frequency. Table 5 -
lists the supported DIMM configurations

NOTE:
Regardless of the DIMM type used, the memory frequency will either be equal to or
less than the processor system bus frequency. For example, if DDR2 667 memories is used
with a 533 MHz system bus frequency processor, the memory will operate at 533 MHz. Table
6 lists the resulting operating memory frequencies based on the combination of DIMMs and
processors.
