DDR2-SDRAM DIMMs
✎
Hardware Reference Guide
The computer comes with double data rate 2 synchronous dynamic
random access memory (DDR2-SDRAM) dual inline memory
modules (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 4GB
of memory configured in a high-performing dual channel mode.
For proper system operation, if the computer supports
DDR2-SDRAM DIMMs, the DIMMs must be:
■
industry-standard 240-pin
■
unbuffered PC2 6400 800 Mhz-compliant*
■
1.8 volt DDR2-SDRAM DIMMs
The DDR2-SDRAM DIMMs must also:
■
support CAS latency 6 (CL=6) for DDR2 / 800 Mhz*
■
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
The system will not start if you install unsupported DIMMs.
*Can downgrade support to PC4200 533 Mhz and PC2 5300 667
Mhz.
