2.6.1 Memory confi gurati ons

You may install up to 4 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 inDIMM_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.

•If installing only one DDRII DIMM, pease install it in DIMM_A1 or A2 first.

•This motherboard does not support memory modules made up of 128 Mb chips or double-sided x16 memory modules.
