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.
