The following figure illustrates the location of the sockets: R P5L13L 128 Pins 112 Pins DIMM_A1 DIMM_B1 P5L13L 240-pin DDR2 DIMM Sockets 2.6.1 Memory configurations You may install up to 2 GB system memory using 256 MB, 512 MB, and 1 GB DDR2 DIMMs. • Installing DDR2 DIMMS other than the recommended configurations may cause memory sizing error or system boot failure. Use any of the recommended configurations in the table on the next page. • Install only identical (the same type and size) DDR2 DIMMs in DIMM_A1 and DIMM_B1. • Always install DIMMs with the same CAS latency. For optimum compatibility, we recommend that you obtain memory modules from the same vendor. • Due to chipset resource allocation, the system may detect less than 2 GB system memory when you installed two 1 GB DDR2 memory. • This motherboard does not support memory modules made up of 128 Mb chips or double-sided x16 memory modules.
