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 three 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 4GB of memory configured in a high-performing dual channel mode.

DDR2-SDRAM DIMMs

For proper system operation, the DIMMs must be:

industry-standard 240-pin

unbuffered PC2-4200 533 MHz

1.8 volt DDR2-SDRAM DIMMs The DDR2-SDRAM DIMMs must also:

support CAS latency 4 (CL = 4) for DDR2/533 MHz

contain the mandatory Joint Electronic Device Engineering Council (JEDEC) DDR2 DIMM specification

In addition, the system 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.

The system will not start if you install unsupported DIMMs.

Refer to the Computer Setup (F10) Utility Guide on the Documentation and Diagnostics CD for information on how to determine the processor bus frequency of a specific computer.
