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 two industry-standard DIMMs.
These memory sockets are populated with at least one preinstalled DIMM. You can populate the system
board with up to either 4 GB per DIMM, for a total of 8GB maximum memory.

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
MHzcompliant
●
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.

Populating DIMM Sockets

There are two DIMM sockets on the system board, single channel memory with two DIMMs per channel.

When installing memory modules:
●
If installing only one memory module, install it in DIMM1.
●
If installing 2 memory modules:
◦ 2 matching memory modules - install in DIMM1 and DIMM2.
◦ 2 non-matching memory modules - install in DIMM1 and DIMM2. Install the larger (GB)
module in DIMM1 and smaller (MB) module in DIMM2.
