Memory The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2SDRAM) dual inline memory modules (DIMMs). CAUTION: DDR and DDR2 memory modules are not interchangeable. DDR2-SDRAM 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. To achieve the maximum memory support, you can populate the system board with up to 2 GB (2 x 1GB) of memory configured in a highperforming dual channel mode. For proper system operation, the DDR2-SDRAM DIMMs must be: ● industry-standard 240-pin ● unbuffered PC2-5300 667 MHz-compliant ● 1.8 volt DDR2-SDRAM DIMMs The DDR2-SDRAM DIMMs must also: ● support CAS latency 4 for PC2-5300 667 MHz ● contain the mandatory JEDEC SPD information In addition, the computer supports: ● 256Mbit, 512Mbit, and 1Gbit 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 start if you install unsupported DIMMs. Installing Memory Modules CAUTION: The memory module sockets have gold metal contacts. When upgrading the memory, it is important to use memory modules with gold metal contacts to prevent corrosion and/ or oxidation resulting from having incompatible metals in contact with each other. CAUTION: Static electricity can damage the electronic components of the computer or optional cards. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object. 42 Chapter 7 Removal and Replacement Procedures- Microtower (MT) Chassis ENWW

Memory
The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2-
SDRAM) dual inline memory modules (DIMMs).
CAUTION:
DDR and DDR2 memory modules are not interchangeable.
DDR2-SDRAM 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. To achieve the maximum memory
support, you can populate the system board with up to 2 GB (2 x 1GB) of memory configured in a high-
performing dual channel mode.
For proper system operation, the DDR2-SDRAM DIMMs must be:
●
industry-standard 240-pin
●
unbuffered PC2-5300 667 MHz-compliant
●
1.8 volt DDR2-SDRAM DIMMs
The DDR2-SDRAM DIMMs must also:
●
support CAS latency 4 for PC2–5300 667 MHz
●
contain the mandatory JEDEC SPD information
In addition, the computer supports:
●
256Mbit, 512Mbit, and 1Gbit 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 start if you install unsupported DIMMs.
Installing Memory Modules
CAUTION:
The memory module sockets have gold metal contacts. When upgrading the
memory, it is important to use memory modules with gold metal contacts to prevent corrosion and/
or oxidation resulting from having incompatible metals in contact with each other.
CAUTION:
Static electricity can damage the electronic components of the computer or optional
cards. Before beginning these procedures, ensure that you are discharged of static electricity by
briefly touching a grounded metal object.
