Populating DIMM sockets (Model 400)
There are two DIMM sockets on the system board, with one socket per channel. The sockets are labeled
DIMM1 and DIMM3. Socket DIMM1 operates in memory channel B. Socket DIMM3 operates in
memory channel A.
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the DIMMs are installed.
NOTE: Single channel and unbalanced dual channel memory configurations will result in inferior
graphics performance.
The system will operate in single channel mode if the DIMM sockets are populated in one channel
only.
The system will operate in a higher-performing dual channel mode if the memory capacity of the
DIMM in Channel A is equal to the memory capacity of the DIMM in Channel B.
The system will operate in flex mode if the memory capacity of the DIMM in Channel A is not
equal to the memory capacity of the DIMM in Channel B. In flex mode, the channel populated
with the least amount of memory describes the total amount of memory assigned to dual channel
and the remainder is assigned to single channel. If one channel will have more memory than the
other, the larger amount should be assigned to Channel A.
In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
Populating DIMM sockets (Model 490)
There are four DIMM sockets on the system board, with two sockets per channel. The sockets are
labeled DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory
channel B. Sockets DIMM3 and DIMM4 operate in memory channel A.
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the DIMMs are installed.
NOTE: Single channel and unbalanced dual channel memory configurations will result in inferior
graphics performance.
The system will operate in single channel mode if the DIMM sockets are populated in one channel
only.
The system will operate in a higher-performing dual channel 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. The
technology and device width can vary between the channels. For example, if Channel A is
populated with two 1-GB DIMMs and Channel B is populated with one 2-GB DIMM, the system
will operate in dual channel mode.
The system will operate in flex 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. In flex mode, the channel
populated with the least amount of memory describes the total amount of memory assigned to dual
channel and the remainder is assigned to single channel. For optimal speed, the channels should
be balanced so that the largest amount of memory is spread between the two channels. If one
channel will have more memory than the other, the larger amount should be assigned to Channel
