Socket Color Black White Black White 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 512MB DIMMs and Channel B is populated with one 1GB 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.

Populating DIMM Sockets

There are four DIMM sockets on the system board, with two sockets per channel. The sockets are

labeled XMM1, XMM2, XMM3, and XMM4. Sockets XMM1 and XMM2 operate in memory channel A.

Sockets XMM3 and XMM4 operate in memory channel B.

NOTE:

A DIMM must occupy the XMM1 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 512MB DIMMs and Channel B is populated with one 1GB 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
