Memory The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2SDRAM) 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. To achieve the maximum memory support, you can populate the system board with up to 2-GB of memory. DDR2-SDRAM DIMMs 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 and 5 for DDR2/667 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 accept PC2-6400 800 MHz DIMMs but will run at a lower frequency. The system will not start if you install unsupported DIMMs. 42 Chapter 6 Removal and Replacement Procedures

Memory
The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2-
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. To achieve the maximum
memory support, you can populate the system board with up to 2-GB of memory.
DDR2-SDRAM DIMMs
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 and 5 for DDR2/667 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 accept PC2-6400 800 MHz DIMMs but will run at a lower frequency.
The system will not start if you install unsupported DIMMs.
