2.5.2 Memory configurations

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

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.For optimum compatibility, it is recommended that you obtain memory modules from qualified vendors. See Qualified Vendors List on page 2-13.

3.It is recommended to use the blue DIMM slot first.4.Stacked RAM and DDR DIMM modules with more than 18 chips are not supported.

5.Always install DIMMs with the same CAS Latency. For optimum compatibility, it is recommended that you obtain memory modules from the same vendors. See Qualified Vendors List on page 2-13.
