2.5.2 Memory Configurations

The motherboard supports system memory of up to 12GB in a two-way interleaved/non-interleaved configuration. The interleaved memory configuration requires that you install identical DDR DIMMs (exactly the same type and size) in pairs. The non-interleaved configuration allows you to install DIMMs in DDR1, DDR3, or DDR5 (see DIMM placement table).

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.

Memory configuration table

DIMM Socket	184-pin ECC DDR DIMM	Total Memory
DDR1	DDR SDRAM 128MB, 256MB, 512MB, 1GB, 2GB	=
DDR2	DDR SDRAM 128MB, 256MB, 512MB, 1GB, 2GB	=
DDR3	DDR SDRAM 128MB, 256MB, 512MB, 1GB, 2GB	=
DDR4	DDR SDRAM 128MB, 256MB, 512MB, 1GB, 2GB	=
DDR5	DDR SDRAM 128MB, 256MB, 512MB, 1GB, 2GB	=
DDR6	DDR SDRAM 128MB, 256MB, 512MB, 1GB, 2GB	=
	Total System Memory (Max. 12GB)

Refer to the following table for the correct DDR DIMM placement.

DIMM placement

	DDR1	DDR2	DDR3	DDR4	DDR5	DDR6
One-DIMM *	—	—	—	—	Installed	—
Two-DIMM **	—	—	—	—	Installed	Installed
Two-DIMM *	—	—	Installed	—	Installed	—

Six-DIMM **	Installed	Installed	Installed	Installed	Installed	Installed

*Memory width is 64-bit; low performance

**Memory width is 128-bit; high performance

If you use a 128-bit memory width configuration, make sure to install identical (the same type and size) DDR DIMM pairs.
