1.7.2 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

Installing DDR DIMMs other than the recommended configurations may cause memory sizing error or system boot failure.

• For optimum compatibility, obtain memory modules from qualified vendors. See Qualified Vendors List on page 1-11.

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 vendor.

Due to hardware limitation, the memory frequency decreases from 400MHz to 333MHz when the three DIMMs are populated at the same time. Refer to the table on 1-11 for DIMM slots setup and corresponding frequency.
