Memory Configurations
The Intel 82945GC GMCH 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.

945GC Chipset
The Intel 945GC chipset consists of the following devices:
•
Intel 82945GC Graphics Memory Controller Hub (GMCH) with Direct Media
Interface (DMI) interconnect
•
Intel 82801GB I/O Controller Hub (ICH7) with DMI interconnect
The GMCH component provides interfaces to the CPU, memory, and the DMI
interconnect. The component also provides integrated graphics capabilities supporting
3D, 2D and display capabilities. The ICH7 is a centralized controller for the board’s
I/O paths.
