Target systems and capacity

This kit adds 2GB of DDR1 memory through two 1GB SODIMM modules. It is built for the listed Dell Inspiron laptops and matches the 200-pin DDR 266MHz specification those systems expect.

Pre-installation checks

Verify that the laptop uses 200-pin DDR SODIMM slots and accepts 2.5V unbuffered, non-ECC memory. Confirm the model number is one of the compatible Inspiron units and that the two available sockets are free for the pair of sticks.

Build and daily use

The modules use major-brand chips without heat spreaders, keeping the profile low for tight notebook bays. Gold-edge 200-pin connectors seat directly in the SODIMM sockets, and the CL2.5 timing operates at standard voltage for stable operation.

Questions about this item

What comes in the box and is anything else needed for installation?

The package contains two 1 GB 200-pin DDR1 SODIMM modules. No extra parts or tools are required to install them in a compatible Dell Inspiron notebook.

Should I choose the 266 MHz or 333 MHz version for my Inspiron 1100?

Both speed ratings refer to the same PC 2100 modules; the 266 MHz figure is the DDR1 data rate and 333 MHz is the PC 2700 label, so either description matches the original specification.

What does the PC 2100 rating mean once the memory is installed in an Inspiron 5100?

PC 2100 identifies the module as DDR1 266 MHz memory with 2.5 V operation and CL2.5 timing, which is the native speed and voltage the Inspiron 5100 memory controller expects.
