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
CAUTION: This product DOES NOT support DDR3 Ultra Low Voltage (DDR3U) memory. The
processor is not compatible with DDR3U memory and if you plug DDR3U memory into the system
board, it can cause the physical damage to the SODIMM or invoke system malfunction.
For proper system operation, the SODIMMs must be:
●
industry-standard 204-pin
●
unbuffered non-ECC PC3-12800 DDR3-1600 MHz-compliant
●
1.5 volt DDR3-SDRAM SODIMMs
The DDR3-SDRAM SODIMMs must also:
●
support CAS latency 11 DDR3 1600 MHz (11-11-11 timing)
●
contain the mandatory Joint Electronic Device Engineering Council (JEDEC) specification
In addition, the computer supports:
●
512-Mbit, 1-Gbit, 2-Gbit, 4-Gbit, and 8-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.
