• 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.
