Populating memory module slots

The system will automatically operate in single channel mode, dual channel mode, or flex mode, depending
on how the memory modules are installed. Refer to the following table to identify the memory module
channel locations.

The system will automatically operate in single channel mode, dual channel mode, or flex mode, depending
on how the memory modules are installed.
The system will operate in single channel mode if the memory module slots are populated in one
●
channel only.
The system will operate in a higher-performing dual channel mode if the memory capacity of the
●
memory module in Channel A is equal to the memory capacity of the memory module in Channel B.
The system will operate in flex mode if the memory capacity of the memory module in Channel A is not
●
equal to the memory capacity of the memory module 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 memory module in the
●
system.
