DDR-SDRAM DIMMs

Hardware Reference Guide
The computer comes with 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
industry-standard DIMMs. These memory module slots are populated
with at least one preinstalled memory module. To achieve the
maximum memory support, you may be required to replace the
preinstalled DIMM with a higher capacity DIMM.
If you are adding a second DIMM or replacing a single smaller
DIMM with two larger DIMMs, both DIMMs should be of the same
speed and capacity in order to achieve a higher performing,
dual-channel mode. The system will automatically operate in
single-channel mode or a higher performing, dual-channel mode,
depending on how the DIMMs are installed.
■
If only one DIMM is installed, the system will operate in a
single-channel mode.
■
If two DIMMs are installed, the system will operate in a
dual-channel mode. The maximum operating speed will be
determined by the slowest DIMM. For example, if the system is
populated with a 266-MHz DIMM and a 333-MHz DIMM, the
system will run at only 266 MHz. For maximum performance
improvement, install identical high-performance DIMMs.
For proper system operation, the DIMMs must be industry-standard
184-pin 2.5 volt DDR-SDRAM DIMMs with appropriate
MHz-compliant CAS Latency:
❏
unbuffered PC 2100 266-MHz-compliant CAS Latency 2 or
2.5 (CL = 2 or CL = 2.5)
or
❏
unbuffered PC 2700 333-MHz-compliant CAS Latency 2.5
(CL = 2.5)
