1.4.1 Memory Configurations
The 3
rd
generation Intel Core processor family and 2
nd
generation Intel Core processor
family processors support the following 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.
