The desktop board has four 240-pin DDR2 DIMM sockets arranged as DIMM 0 (blue) and DIMM 1 (black) in both Channel A and Channel B.

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 in DIMM 0 (blue) of both channels A and B (see Figure 13).

Channel A

1 GB, 533 MHz

Channel B

1 GB, 533 MHz

DIMM 0 DIMM 1
