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.
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 =

Total System Memory (Max. 12GB)
The system chipset only supports PC2100/1600 registered ECC
DIMMs. Make sure to use only the specified DIMM types for stable
system operation.

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