Note:
• In the second column, "DS" refers to double-sided memory modules (containing
two rows of DDR SDRAM) and "SS" refers to single-sided memory modules
(containing one row of DDR SDRAM).
• It is possible to install four 2048 MB (2 GB) modules for a total of 8 GB of system
memory, however, only 4 GB of address space is available.
Memory Configurations
The Intel 82915G GMCH supports two types of memory organisation:
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.
Note: The DIMM0 sockets of both channels are blue. The DIMM1 sockets of both
channels are black.
