2.4.2Memory configurations

You may install 256 MB, 512 MB and 1 GB unbuffered non-ECC DDR DIMMs into the DIMM sockets using the memory configurations in this section.

• Installing DDR DIMMs other than the recommended configurations may cause memory sizing error or system boot failure. Use any of the recommended configurations in Table 1.

•In dual-channel configurations, install only identical (the same type and size) DDR DIMM pairs for each channel.

•Always install DIMMs with the same CAS latency. For optimum compatibility, it is recommended that you obtain memory modules from the same vendor.

•Due to chipset resource allocation, the system may detect less than 4 GB system memory when you installed four 1 GB DDR memory modules.
