Installing Additional Memory
The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2-
SDRAM) small outline dual inline memory modules (SODIMMs).
SODIMMs
The memory sockets on the system board can be populated with up to two industry-standard SODIMMs.
These memory sockets are populated with at least one preinstalled SODIMM. To achieve the maximum
memory support, you can populate the system board with up to 4GB of memory.
DDR2-SDRAM SODIMMs
For proper system operation, the SODIMMs must be:
●
industry-standard 200-pin
●
unbuffered PC2-5300 667 MHz-compliant or PC2-6400 800 MHz-compliant
●
1.8 volt DDR2-SDRAM SODIMMs
The DDR2-SDRAM SODIMMs must also:
●
support CAS latency 5 DDR2 667 Mhz (5-5-5 timing) and CAS latency 6 DDR2 800 Mhz (6-6-6
timing)
●
contain the mandatory Joint Electronic Device Engineering Council (JEDEC) specification
In addition, the computer supports:
●
512Mbit and 1Gbit non-ECC memory technologies
●
single-sided and double-sided SODIMMS
●
SODIMMs constructed with x8 and x16 devices; SODIMMs constructed with x4 SDRAM are not
supported
NOTE: The system will not operate properly if you install unsupported SODIMMs.
Refer to the Computer Setup (F10) Utility Guide for information on how to determine the processor bus
frequency of a specific computer.
