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 
DDR3-SDRAM  SODIMMs
For proper system operation, the SODIMMs must be:
●
●unbuffered 
●1.35 volt or 1.5 volt 
The 
●support CAS latency 11 DDR3 1600 MHz 
●contain the mandatory Joint Electronic Device Engineering Council (JEDEC) specification In addition, the computer supports:
●
●
●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.
NOTE: The system will not operate properly if you install unsupported SODIMMs.
