Installing additional memory
The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3-
SDRAM) dual inline memory modules (DIMMs).
DIMMs
The memory sockets on the system board can be populated with up to four industry-standard DIMMs.
These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum
memory support, you can populate the system board with up to 32-GB of memory configured in a
high-performing dual channel mode.
DDR3-SDRAM DIMMs
For proper system operation, the DDR3-SDRAM DIMMs must be:
● industry-standard 240-pin
●
unbuffered non-ECC PC3-12800 DDR3-1600 MHz-compliant
●
1.35 volt or 1.5 volt DDR3/DDR3L-SDRAM DIMMs
The DDR3-SDRAM DIMMs must also:
●
support CAS latency 11 DDR3 1600 MHz (11-11-11 timing)
● contain the mandatory JEDEC SPD information
