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 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:
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.
CAUTION:
When handling a memory module, be careful not to touch any of the contacts. Doing so
may damage the module.
1.
Prepare the computer for disassembly (
Preparation for Disassembly on page 26
2.
Remove the access panel and lay the computer down on its side to make it easier to work on
(
WARNING!
To reduce risk of personal injury from hot surfaces, allow the internal system
components to cool before touching.
