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 DDR1 DDR2 DDR3 DDR4 DDR5 DDR6 184-pin ECC DDR DIMM Total Memory DDR SDRAM 128MB, 256MB, 512MB, 1GB, 2GB = DDR SDRAM 128MB, 256MB, 512MB, 1GB, 2GB = DDR SDRAM 128MB, 256MB, 512MB, 1GB, 2GB = DDR SDRAM 128MB, 256MB, 512MB, 1GB, 2GB = DDR SDRAM 128MB, 256MB, 512MB, 1GB, 2GB = DDR SDRAM 128MB, 256MB, 512MB, 1GB, 2GB = Total System Memory (Max. 12GB) Refer to the following table for the correct DDR DIMM placement.
