Installing Additional Memory
The computer comes with double data rate synchronous dynamic
random access memory (DDR-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.
DDR DIMMs
For proper system operation, the DIMMs must be:
■ industry-standard 184-pin
■ unbuffered PC 2700 333 Mhz-compliant or PC3200 400
Mhz-compliant
■ 2.5 volt DDR-SDRAM DIMMs
The DDR-SDRAM DIMMs must also:
■ support CAS Latency 2.5 or 3 (CL = 2.5 or CL = 3)
■ contain the mandatory Joint Electronic Device Engineering
Council (JEDEC) Serial Presence Detect (SPD) information
In addition, the system supports:
■ 256-Mbit, 512-Mbit, and 1-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.
✎
The system will not start using unsupported DIMMs.
