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 in Table 4.
