Installing Additional Memory The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3SDRAM) 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 8-GB of memory configured in a highperforming dual channel mode. DDR3-SDRAM DIMMs For proper system operation, the DDR3-SDRAM DIMMs must be: ● industry-standard 240-pin ● unbuffered PC3-8500 1066 MHz-compliant ● 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 8 DDR3 1066 Mhz (8-8-8 timing) ● contain the mandatory JEDEC SPD information In addition, the computer supports: ● 512Mbit, 1Gbit, and 2Gbit 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. 36 Chapter 6 Removal and Replacement Procedures Microtower (MT) Chassis

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 8-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 PC3-8500 1066 MHz-compliant
●
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 8 DDR3 1066 Mhz (8-8-8
timing)
●
contain the mandatory JEDEC SPD information
In addition, the computer supports:
●
512Mbit, 1Gbit, and 2Gbit 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.
