Populating DIMM Sockets
2-8
The following processor bus frequencies are required for the system
to run at the supported memory frequencies.
Memory Frequency
333 MHz
400 MHz
If a memory frequency is paired with an unsupported processor bus
frequency, the system will run at the highest supported memory
speed. For example, if a 400 MHz DIMM is paired with a 533 MHz
processor bus, the system will run at 400 MHz, the highest supported
memory speed.
The system will not start if you install unsupported DIMMs.
Refer to the Computer Setup (F10) Utility Guide on the
Documentation CD for information on how to determine the
processor bus frequency of a specific computer.
The system will automatically operate in single channel mode, dual
channel Asymmetric mode, or a higher-performing dual channel
Interleaved mode, depending on how the DIMMs are installed.
■
The system will operate in single channel mode if the DIMM
sockets are populated in one channel only.
■
The system will operate in dual channel Asymmetric mode if the
total memory capacity of the DIMMs in Channel A is not equal to
the total memory capacity of the DIMMs in Channel B.
■
The system will operate in a higher-performing dual channel
Interleaved mode if the total memory capacity of the DIMMs in
Channel A is equal to the total memory capacity of the DIMMs in
Channel B. However, the technology and device width can vary
between the channels. For example, if Channel A is populated
with two 256MB DIMMS and Channel B is populated with one
512MB DIMM, the system will operate in Interleaved mode.
