1.4.1 Memory Configurations

The Intel 82955X MCH supports two types of memory organization:
•
Dual channel (Interleaved) mode. This mode offers the highest throughput for real world
applications. Dual channel mode is enabled when the installed memory capacities of both
DIMM channels are equal. Technology and device width can vary from one channel to the
other but the installed memory capacity for each channel must be equal. If different speed
DIMMs are used between channels, the slowest memory timing will be used.
•
Single channel (Asymmetric) mode. This mode is equivalent to single channel bandwidth
operation for real world applications. This mode is used when only a single DIMM is installed
or the memory capacities are unequal. Technology and device width can vary from one
channel to the other. If different speed DIMMs are used between channels, the slowest
memory timing will be used.
Figure 3 illustrates the memory channel and DIMM configuration.
NOTE
The DIMM0 sockets of both channels are blue. The DIMM1 sockets of both channels are black.
