Intel Desktop Board D845PEMY Product Guide
Main Memory
NOTE
To be fully compliant with all applicable Intel® SDRAM memory specification addendums, the desktop 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.
NOTE
All memory components and DIMMs used with the desktop board must comply with the PC SDRAM specifications. These include the PC SDRAM Specification (memory component specific) and the PC Unbuffered DIMM Specification.
The desktop board supports single channel memory configurations defined in Table 4.
