1.7.2 Memory 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.

•Always install DIMMs with the same CAS latency. For optimum compatibility, it is recommended that you obtain memory modules from the same vendor. See Table 2 for qualified DDR DIMMs.

•Due to chipset limitation, DIMM modules with 128 Mb memory chips or double-sided x16 memory chips are not supported in this motherboard.

•When you installed four 1 GB DDR memory modules, the system may detect not more than 3 GB of total system memory because of address space allocation. This limitation applies only to systms with Windows® XP 32-bit operating system since it does not support PAE (Physical Address Extension) mode.

•If you installed Windows® XP 32-bit operationg system, we recommend you to install not more than 3 GB of system memory.
