System memory
The motherboard comes with six Double Data Rate (DDR) Dual Inline
Memory Module (DIMM) sockets. These sockets support up to 12GB
system memory using 2.5V 184-pin registered ECC PC2100/PC1600 DDR
DIMMs.

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.

The system chipset only supports PC2100/PC1600 registered ECC
DIMMs. Make sure th use only the specified DIMM types for stable
system operation.
