The system will automatically operate in single channel mode or dual channel mode, depending on how
the DIMMs are installed.
●
The system will operate in a higher-performing dual channel mode if like-sized DIMMs of equal
capacity are populated in one or both pairs of sockets. For example, if the Channel A XMM1 socket
and Channel B XMM2 socket (the two black sockets) both have 1024MB DIMMs installed, the
system will operate in dual channel mode. If this system had two additional DIMMs added into the
blue sockets, they could be a pair of 512MBor 1024MB DIMMs and the system would still operate
in dual channel mode. For purposes of “like sizes,” a single-sided 512MB DIMM and a double-sided
512MB DIMM would not be the same size because they have different numbers of memory chips
on them.
●
The system will operate in single channel mode if the DIMMs are populated in any other supported
configuration. Supported configurations consist of any combination of one, two, three, or four
DIMMs as long as socket XMM1 is populated before socket XMM3 in Channel A, and socket XMM2
is populated before socket XMM4 in Channel B.
●
If a single DIMM is installed, it must be installed in the XMM1 socket.
●
In either mode, the maximum operational speed is determined by the slowest DIMM in the system.
