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 4 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 PC2-5300 667 MHz-compliant

1.8 volt DDR2-SDRAM DIMMs

The DDR2-SDRAM DIMMs must also:

support CAS latency 4 and 5 for DDR2/667 MHz

contain the mandatory JEDEC SPD information In addition, the computer supports:

256Mbit, 512Mbit, and 1Gbit 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 start if you install unsupported DIMMs.
