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 allows

the BIOS to read the SPD data and program the chipset to accurately configure memory settings

for optimum performance.
