Important notes on memory configurations 1. 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. 2. In Dual-channel configurations, install only identical (the same type and size) DDR DIMM pairs for each channel. 3. Always install DIMMs with the same CAS latency. For optimum compatibility, it is recommended that you obtain memory modules from the same vendor. See list of Qualified Vendors List on page 2-12. 4. When all four sockets are populated with 1GB DIMMs (total 4GB), the system may detect only 3+GB (a little less than 4GB) due to the Southbridge resource allocation. 5. It is recommended to use the blue DIMM slots first. ASUS SK8N motherboard 2-11
