2.5.2 Memory Configurations

The motherboard supports system memory of up to 12GB in a two-way interleaved or non-interleaved configuration. The two-way interleaved configuration requires that you install identical DDR DIMMs (exactly the same type and size) in pairs. For example, if you installed a 512MB module into DDR1, you must install the same type of 512MB module into DDR2. The same rule applies to pairs DDR3/DDR4 and DDR5/DDR6.

The non-interleaved configuration allows you to install one DIMM into DDR1 socket (the socket closest to the ATX power connector). Installing a single DIMM into any other socket does not work.

The following table lists the DIMM socket pairs and the memory modules that you can install.

DIMM Socket	184-pin registered DDR DIMM		Total Memory
DDR1	SDRAM 128MB, 256MB, 512MB, 1GB, 2GB		x1
DDR2	SDRAM 128MB, 256MB, 512MB, 1GB, 2GB		x1
DDR3	SDRAM 128MB, 256MB, 512MB, 1GB, 2GB		x1
DDR4	SDRAM 128MB, 256MB, 512MB, 1GB, 2GB		x1
DDR5	SDRAM 128MB, 256MB, 512MB, 1GB, 2GB		x1
DDR6	SDRAM 128MB, 256MB, 512MB, 1GB, 2GB		x1

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