Memory Configurations
The Vig390s with Intel E7525 MCH supports Dual channel (Interleaved) mode
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 DIMM A2 and B2 sockets of both channels are blue. The DIMM A1and B1
sockets of both channels are black.

Dual channel mode: Installed modules must be the same therefore for 1GB total
system memory two 512MB modules would be installed in sockets A1 and B1.
