2.4.2 Memory configurations

You may install 64MB, 128MB, 256MB, 512MB, and 1GB unbuffered ECC and non-ECC DDR DIMMs into the DIMM sockets using the memory configurations in this section.

Important notes on memory configurations

• 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.

•In Dual-channel configurations, install only identical (the same type and size) DDR DIMM pairs for each channel.

•Use the blue DIMM slots first.

•Stacked RAM and DDR DIMM modules with more than 18 chips are not supported.

•Always install DIMMs with the same CAS Latency. For optimum compatibility, obtain memory modules from the same vendors. See Qualified Vendors List on page 2-13.

•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.
