Installing Additional Memory
The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3-
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 8-GB of memory.
DDR3-SDRAM SODIMMs
For proper system operation, the SODIMMs must be:
● industry-standard 204-pin
● unbuffered non-ECC PC3-8500 DDR3-1066 MHz-compliant or PC3-10600 DDR3-1333 MHz-
compliant
● 1.5 volt DDR3-SDRAM SODIMMs
The DDR3-SDRAM SODIMMs must also:
● support CAS latency 7 DDR3 1066 MHz (7-7-7 timing) and CAS latency 9 DDR3 1333 MHz (9-9-9
timing)
● contain the mandatory Joint Electronic Device Engineering Council (JEDEC) specification
In addition, the computer supports:
● 512-Mbit, 1-Gbit, and 2-Gbit 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.
