Installing Additional Memory

The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3- SDRAM) dual inline memory modules (DIMMs).

DIMMs

The memory sockets on the system board can be populated with up to four industry-standard DIMMs. These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum memory support, you can populate the system board with up to 16-GB of memory configured in a high- performing dual channel mode.

DDR3-SDRAM DIMMs

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

industry-standard 240-pin

unbuffered non-ECC PC3-8500 DDR3-1066 MHz-compliant or PC3-10600 DDR3-1333 MHz- compliant

NOTE: 1333 MHz DIMMS will only run at a speed of 1066 MHz.

1.5 volt DDR3-SDRAM DIMMs The DDR3-SDRAM DIMMs must also:

support CAS latency 7 DDR3 1066 MHz (7-7-7 timing) and 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.
