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
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 8GB
(1-Gbit Technology) of memory configured in a high-performing
dual channel mode.
✎
The memory available may be limited by the operating system.
DDR-SDRAM DIMMs
For proper system operation, if the computer supports DDR-SDRAM
DIMMs, the DIMMs must be:
■ industry-standard 184-pin
■ unbuffered PC3200 400 MHz-compliant
■ 2.5 volt DDR-SDRAM DIMMs.
The DDR-SDRAM DIMMs must also:
■ support CAS latency 3 (CL = 3)
■ contain the mandatory JEDEC SPD information
In addition, the computer supports:
■ 128Mbit, 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.
