Removing the Processor

For instructions on how to remove the processor fan heat sink and processor, refer to
the processor installation manual.

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.

The desktop board has two 240-pin DDR2 DIMM sockets providing Channel A and
Channel B. For dual-channel performance, install a matched pair of DIMMs equal in
speed and size (see Figure 13).

Figure 13. Dual Channel Memory Configuration Example

NOTE

All other memory configurations will result in single-channel memory operation.
