Installing Additional Memory

The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2-
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 8-GB of memory configured in a high-
performing dual channel mode.

DDR2-SDRAM DIMMs

For proper system operation, the DDR2-SDRAM DIMMs must be:

●

industry-standard 240-pin

●

unbuffered PC2-6400 800 MHz-compliant

●

1.8 volt DDR2-SDRAM DIMMs

The DDR2-SDRAM DIMMs must also:

●

support CAS latency 5 DDR2 800 Mhz (5-5-5 timing) and CAS latency 6 DDR2 800 Mhz (6-6-6
timing)

●

contain the mandatory JEDEC SPD information

In addition, the computer supports:

●

512Mbit, 1Gbit, and 2Gbit 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.
