MUSHKIN 512 MB PC2100 DDR SODIMM 1×0.5 GB 266 MHz CAS 2.5 laptop memory module

MUSHKIN 512 MB PC2100 DDR SODIMM is a 0.5 GB internal DDR laptop memory module designed for compact notebooks and small-form-factor PCs that accept PC2100 SODIMM modules. The module runs at a 266 MHz memory clock (PC2100) with CAS latency 2.5 and a single-module 1×0.5 GB configuration. This module is intended for upgrading or replacing low-capacity systems where a PC2100 DDR SODIMM is required and where improved stability and compatibility with original memory timings are desired.

Advantages

The module’s modest capacity and standard SODIMM form factor make it compatible with many older laptops and embedded systems that specify PC2100 DDR memory. Operating at 266 MHz with CAS 2.5, the memory uses timings optimized for compatibility with existing system memory, reducing the likelihood of timing-related instability. Its single-module layout simplifies installation and reduces the need for matching pairs in systems that accept single SODIMM modules.

Suitable for

• Upgrading older laptops or netbooks that accept PC2100 DDR SODIMM modules
• Replacing faulty or missing 256–512 MB modules in legacy systems
• Small form factor desktops and embedded systems requiring a 200-pin SODIMM DDR module
• Systems where low-power, compact DDR memory with CAS 2.5 timing is required

Key specifications

• Memory type: DDR SODIMM (200-pin)
• Capacity: 512 MB (0.5 GB) single module
• Speed grade: PC2100 (266 MHz)
• CAS latency: 2.5
• Module configuration: 1×0.5 GB
• Form factor: laptop SODIMM

How to use

Power off the laptop or compact PC and disconnect all power sources, including battery if removable. Access the memory compartment according to the device manufacturer’s instructions and carefully remove the existing SODIMM if present by releasing the retaining clips. Align the MUSHKIN module’s notch with the socket, insert the SODIMM at the correct angle and press gently until the clips snap into place. Reassemble the device, reconnect power, and boot to confirm the system recognizes the installed memory. If the system does not boot or reports incorrect memory, recheck seating and compatibility with the motherboard’s supported memory types.

Usage recommendations

Use this module in systems explicitly specifying PC2100 DDR SODIMM support. When mixing modules, match speed and timings where possible to avoid instability. Handle the module with proper electrostatic discharge (ESD) precautions and consult the device manual for maximum supported memory and configuration guidelines.
