Figure 8-5 DIMM Socket Locations Table 8-1 DIMM Socket Locations Item Description Socket Color 1 DIMM1 socket, Channel A (populate first) Black 2 DIMM2 socket, Channel A (populate third) White 3 DIMM3 socket, Channel B (populate second) White 4 DIMM4 socket, Channel B (populate fourth) White NOTE: A DIMM must occupy the black DIMM1 socket. Otherwise, the system will display a POST error message indicating that a memory module must be installed in the wrong 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 512-MB DIMMs and Channel B is populated with one 1-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 A. For example, if you are populating the sockets with one 1-GB DIMM, and three 512-MB DIMMs, Channel A should be populated with the 1-GB DIMM and one 512-MB DIMM, and Channel B should be populated with the two 512-MB DIMMs. With this configuration, 2-GB will run as dual channel and 512-MB will run as single channel. ● In any mode, the maximum operational speed is determined by the slowest DIMM in the system.

DIMM Socket Locations

Item

Description

Socket Color

DIMM1 socket, Channel A (populate first)

Black

DIMM2 socket, Channel A (populate third)

White

DIMM3 socket, Channel B (populate second)

White

DIMM4 socket, Channel B (populate fourth)

White

NOTE:

A DIMM must occupy the black DIMM1 socket. Otherwise, the system will

display a POST error message indicating that a memory module must be installed in the

wrong 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 512-MB DIMMs and Channel B is populated with one 1-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 A. For

example, if you are populating the sockets with one 1-GB DIMM, and three 512-MB DIMMs,

Channel A should be populated with the 1-GB DIMM and one 512-MB DIMM, and Channel B should

be populated with the two 512-MB DIMMs. With this configuration, 2-GB will run as dual channel

and 512-MB will run as single channel.

●

In any mode, the maximum operational speed is determined by the slowest DIMM in the system.
