Intel-Based Systems
Computers equipped with Intel-based processors come 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 module slots are populated with at least one preinstalled memory
module. 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, the DDR2-SDRAM DIMMs must be industry-standard 240-pin,
unbuffered PC3200 400 MHz-compliant or PC4300 533 MHz-compliant, 1.8 volts.
The DDR2-SDRAM DIMMs must also:
support CAS latency 3, 4, or 5(CL = 3, CL = 4, or CL = 5) for DDR2/400 MHz; support CAS
latency 4 or 5(CL = 4, or CL = 5) for DDR2/533 MHz
contain the mandatory JEDEC SPD information
In addition, the computer supports:
256Mbit, 512Mbit, and 1 Gbit 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
The following processor bus frequencies are required for the system to run at the supported
memory frequencies.
The system will not start if you install unsupported DIMMs.
