Populating DIMM Sockets
There are four DIMM sockets on the system board, with two sockets per channel.
Populate the DIMM sockets in the following order: DIMM1 then DIMM2
Figure 6-4 DIMM Socket Locations
Table 6-1 DIMM Socket Locations
Item Description Socket Color Insertion Order
1 DIMM1 socket, Channel A
(populate first)
White 1
2 DIMM2 socket, Channel A White 2
NOTE: A DIMM must occupy the DIMM1 socket.
The system will automatically operate in single channel mode, dual channel mode, or flex 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 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.
