Memory
Description
2-GB memory module (PC3-10600, 1333-MHz)
1-GB memory module (PC3-10600, 1333-MHz)
The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3-
SDRAM) dual inline memory modules (DIMMs).
DDR3-SDRAM 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 8 GB of memory configured in a high-
performing dual channel mode.
For proper system operation, the DDR3-SDRAM DIMMs must be:
●
industry-standard 240-pin
●
unbuffered non-ECC PC3-10600 DDR3-1333 MHz-compliant
●
1.5 volt DDR3-SDRAM DIMMs
The DDR3-SDRAM DIMMs must also:
●
support 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.
The system will automatically operate in single channel mode, dual channel mode, or flex mode,
depending on how the DIMMs are installed.
●
The system will operate in single channel mode if the DIMM sockets are populated in one
channel only.
●
The system will operate in a higher-performing dual channel mode if the total memory capacity
of the DIMMs in Channel A is equal to the total memory capacity of the DIMMs in Channel B.
The technology and device width can vary between the channels. For example, if Channel A is
populated with two 1-GB DIMMs and Channel B is populated with one 2-GB DIMM, the system
will operate in dual channel mode.
