Intel manual Main Memory, Desktop Board D945GNT/D945GTP Memory Configurations

Desktop Board Features

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 dual or single channel memory configurations defined in Table 6.
