System Memory Update
The 8-GB DIMMs that are supported on your system are 533-MHz quad-rank
modules. All other sizes of supported DIMMs—512-MB, 1-GB, 2-GB, and
4-GB—are 667-MHz modules. Operating a system with a mix of 533-MHz
and 667-MHz DIMMs forces all DIMMs to operate at the slower 533-MHz
signal rate. Therefore, mixed memory configurations with 8-GB DIMMs are
not supported on your system and will result in an error message at startup
to indicate that the memory configuration is not optimal. Table 1-3 and
Table 1-4 provide updates to your system’s Hardware Owner’s Manual
regarding the currently supported system memory configurations and
memory sparing configurations.
Table 1-3.
