2.4.2 Memory Configurations
The motherboard supports system memory of up to 12GB in a two-way
interleaved configuration. As a rule, this configuration requires that you
install identical DDR DIMMs (exactly the same type and size) in pairs for
optimum performance. For example, if you installed a 512MB module into
DDRA1, you must install the same type of 512MB module into DDRA2.
The same rule applies to pairs DDRB1/DDRB2 and DDRC1/DDRC2.
The only exception to the above rule allows you to install one DIMM into
DDRA1 socket (the socket closest to the ATX power connector). Installing
a single DIMM into any other socket would not work.
The following table lists the DIMM socket pairs and the memory modules
that you can install.

The system chipset only supports PC2100/1600 registered ECC
DIMMs. Make sure to use only the specified DIMM types for stable
system operation.
