resources. The BIOS will display the total amount of installed memory and the
amount of configured memory.
DIMM installed. If your system has one DIMM installed, when you install an
additional DIMM, it must be installed in DIMM 3 memory connector, and must
be the same size, speed, type, and technology as the DIMM installed in DIMM 1
memory connector. You can mix compatible DIMMs from various manufacturers.
When one DIMM is installed in the system, the system runs as a single-channel
machine. When you add a DIMM in DIMM 3 memory connector, your system
defaults to a dual-channel machine.
DIMM 1 and DIMM 3 memory connectors must be the same size, speed, type,
and technology. You can mix compatible DIMMs from various manufactures. If
you install a second pair of DIMMs in DIMM 2 and DIMM 4 memory connectors,
they do not have to be the same size, speed, type, and technology as the
DIMMs installed in DIMM 1 and DIMM 3 memory connectors. However, the size,
speed, type, and technology of the DIMMs you install in DIMM 2 and DIMM 4
memory connectors must match each other.
