The following figure illustrates the location of the sockets: ® DIMM_A1 DIMM_A2 DIMM_B1 DIMM_B2 P5GV-MX P5GV-MX 184-pin DDR DIMM Sockets 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. 1-16 Chapter 1: Product introduction
