2.3System 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.
