For proper system operation, the DDR3-SDRAM DIMMs must be: ● industry-standard 240-pin ● unbuffered non-ECC PC3-10600 DDR3-1333 MHz-compliant ● 1.5 volt DDR3-SDRAM DIMMs The DDR3-SDRAM DIMMs must also: ● support CAS latency 9 DDR3 1333 MHz (9-9-9 timing) ● contain the mandatory JEDEC SPD information In addition, the computer supports: ● 512-Mbit, 1-Gbit, and 2-Gbit non-ECC memory technologies ● single-sided and double-sided DIMMs ● DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not supported NOTE: The system will not operate properly if you install unsupported DIMMs. Populating DIMM Sockets Populate the DIMM sockets in the following order: XMM1, XMM3 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. If Channel A is populated with one 1-GB DIMM and Channel B is populated with one 2-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. If you are populating the sockets with one 2-GB DIMM, and one 1-GB DIMM, Channel A should be populated with the 2-GB DIMM, and Channel B should be populated with the 1-GB DIMM. With this configuration, 2 GB will run as dual channel and 1 GB will run as single channel. ● In any mode, the maximum operational speed is determined by the slowest DIMM in the system. The system will automatically operate in single channel mode, dual channel mode, or flex mode, depending on how the DIMMs are installed. 48 Chapter 7 Removal and Replacement Procedures - Microtower (MT) Chassis

For proper system operation, the DDR3-SDRAM DIMMs must be:

●

industry-standard 240-pin

●

unbuffered non-ECC PC3-10600 DDR3-1333 MHz-compliant

●

1.5 volt DDR3-SDRAM DIMMs

The DDR3-SDRAM DIMMs must also:

●

support CAS latency 9 DDR3 1333 MHz (9-9-9 timing)

●

contain the mandatory JEDEC SPD information

In addition, the computer supports:

●

512-Mbit, 1-Gbit, and 2-Gbit non-ECC memory technologies

●

single-sided and double-sided DIMMs

●

DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not

supported

NOTE:

The system will not operate properly if you install unsupported DIMMs.

Populating DIMM Sockets

Populate the DIMM sockets in the following order: XMM1, XMM3

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. If Channel A is populated with

one 1-GB DIMM and Channel B is populated with one 2-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. If you are populating the sockets with one 2-GB DIMM, and one 1-GB DIMM,

Channel A should be populated with the 2-GB DIMM, and Channel B should be populated with

the 1-GB DIMM. With this configuration, 2 GB will run as dual channel and 1 GB will run as

single channel.

●

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

The system will automatically operate in single channel mode, dual channel mode, or flex mode,

depending on how the DIMMs are installed.
