DIMM Considerations and Limitations
When installing DIMMs, consider the following DIMM limitations:
■
DIMMs are available in two speeds: 1066 MHz and 1333 MHz.
■
DIMM speed rules are as follows:
■
Three of the same kind of DIMMs per channel = 800 MHz
■
Two of the same kind of DIMMs per channel = 1333 MHz (for single-rank and dual-
rank DIMMs); = 800 MHz (for quad-rank DIMMs)
■
One of the same kind of DIMMs per channel = 1333 MHz (if using 1333 MHz DIMMs)
Note -
This DIMM configuration requires CPUs supporting 1333MHz.
■
One of the same kind of DIMMs per channel = 1066 MHz (if using 1066 MHz DIMMs)
■
The system operates all memory only as fast as the slowest DIMM configuration.
