2.3.1 Memory configurations
As a rule, you need to install identical DDR DIMMs (exactly the same type
and size) in pairs. 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.
An exception to this rule allows you to install one DIMM into the 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.
