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 16-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 PC3-8500 DDR3-1066 MHz-compliant or PC3-10600 DDR3-1333 MHz-
compliant
NOTE:
1333 MHz DIMMS will only run at a speed of 1066 MHz.
●
1.5 volt DDR3-SDRAM DIMMs
The DDR3-SDRAM DIMMs 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 JEDEC SPD information
In addition, the computer supports:
●
512-Mbit, 1-Gbit, and 2-Gbit non-ECC memory technologies
●
single-sided and double-sided DIMMs
●
DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not
supported
NOTE:
The system will not operate properly if you install unsupported DIMMs.
