Installing and Removing Memory
NOTE
To be fully compliant with all applicable Intel SDRAM memory specifications, the board
requires DIMMs that support the Serial Presence Detect (SPD) data structure.
Intel Desktop board DP45SG has four 240-pin DDR3 DIMM sockets arranged as
DIMM 0 and DIMM 1 in both Channel A and Channel B.
NOTE
Regardless of the memory configuration used (dual or single channel), Channel A,
DIMM 0 must always be populated. This is a requirement of the ICH10R Manageability
Engine feature.
Guidelines for Dual Channel Memory Configuration
Before installing DIMMs, read and follow these guidelines for dual channel
configuration.
Two or Four DIMMs
Install a matched pair of DIMMs equal in speed and size (see Figure 14) in DIMM 0
(blue) of channels A and B.
