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.

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