DDR2-SDRAM DIMMs

✎
Hardware Reference Guide
The computer comes with double data rate 2 synchronous dynamic
random access memory (DDR2-SDRAM) dual inline memory
modules (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.
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.
