Dual Channel Memory Configuration
GA-945PL-DS3/GA-945PL-S3 supports the Dual Channel Technology. After
operating the Dual Channel Technology, the bandwidth of Memory Bus will
add double.
GA-945PL-DS3/GA-945PL-S3 includes 4 DIMM sockets, and each Channel has two DIMM sockets as
following:
Channel 0 : DDRII1, DDRII2
Channel 1 : DDRII3, DDRII4
If you want to operate the Dual Channel Technology, please note the following explanations due
to the limitation of Intel chipset specifications.
1. Dual Channel mode will not be enabled if only one/three DDRII memory module is
installed.
2. To enable Dual Channel mode with two or four memory modules (it is recommended to
use memory modules of identical brand, size, chips, and speed), install the memory
according to the dual channel memory configuration table below (Figure 1).
Memory configurations in Figure 2 will result in memory frequency being reduced from 533MHz down
to 400MHz. (DS: Double Side, SS: Single Side, X: Empty)

Because of chipset limitations, do not populate both DIMM sockets of the same channel with
double-sided memory modules to prevent system's failure to start or incorrect detection of
memory modules,
