Intel Desktop Board D865PERL Product Guide Installing and Removing Memory CAUTION To be fully compliant with all applicable Intel SDRAM memory specifications, the boards require DIMMs that support the Serial Presence Detect (SPD) data structure. You can access the PC Serial Presence Detect Specification at: http://www.intel.com/technology/memory/pcsdram/spec/ Desktop Board D865PERL has four 184-pin DIMM sockets arranged as DIMM 0 and DIMM 1 in both Channel A and Channel B, as shown in Figure 9 (color was added to DIMM sockets to show how to place DIMMs for dual configuration). Dual Channel Configuration Before installing DIMMs, read and follow these guidelines for dual channel configuration. Install a matched pair of DIMMs equal in speed, size, and technology (see Figure 7) in DIMM 0 in both channels A and B.

Installing and Removing Memory
CAUTION
To be fully compliant with all applicable Intel SDRAM memory specifications, the boards require
DIMMs that support the Serial Presence Detect (SPD) data structure.
You can access the PC
Serial Presence Detect Specification at:
Desktop Board D865PERL has four 184-pin DIMM sockets arranged as DIMM 0 and DIMM 1 in
both Channel A and Channel B, as shown in Figure 9 (color was added to DIMM sockets to show
how to place DIMMs for dual configuration).
Dual Channel Configuration
Before installing DIMMs, read and follow these guidelines for dual channel configuration.
Install a matched pair of DIMMs equal in speed, size, and technology (see Figure 7) in
DIMM 0 in both channels A and B.
