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
industry-standard DIMMs. These memory module slots are populated
with at least one preinstalled memory module. To achieve the
maximum memory support, you may be required to replace the
preinstalled DIMM with a higher capacity DIMM.
The system board can be populated with up to 4GB of memory and
supports single-channel or dual-channel mode.
✎
For more information about single-channel or dual-channel memory
modes, see the section
“Single and Dual Channel Modes” on page 8
.
DDR-SDRAM DIMMs
For proper system operation, if the computer supports DDR-SDRAM
DIMMs, the DIMMs must be:
■
industry-standard 184-pin
■
unbuffered PC2100 266 MHz-, PC2700 333 MHz-, or PC3200
400 MHz-compliant
■
2.5 volt DDR-SDRAM DIMMs.
The DDR-SDRAM DIMMs must also:
■
support CAS latency 2, 2.5, or 3 (CL = 2, CL = 2.5, or CL = 3)
■
contain the mandatory JEDEC SPD information
In addition, the computer supports:
■
128Mbit, 256Mbit, and 512Mbit 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
