Memory
Your workstation has double data rate synchronous dynamic random access memory
(DDR-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, if the workstation supports DDR-SDRAM DIMMs, the DIMMs
must be industry-standard 184-pin, PC2700 333 MHz-, or PC3200 400 MHz-compliant, 2.5 volt
DDR-SDRAM DIMMs. The DDR-SDRAM DIMMs must also:
■
support CAS latency 2, 2.5, or 3 (CL = 2, CL = 2.5, CL=3)
■
contain the mandatory JEDEC SPD information
In addition, the workstation supports:
■
128Mbit, 256Mbit, and 512Mbit 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.
If a memory frequency is paired with an unsupported processor bus frequency, the system will
run at the highest supported memory speed. For example, if a 333 MHz DIMM is paired with a
400 MHz processor bus, the system will run at the lower supported memory speed.
✎
The system will not start if you install unsupported DIMMs.
