1 GB memory upgrade for ThinkPad T40 T41 T42

This module adds one gigabyte of system-specific memory to compatible IBM ThinkPad models. It targets owners of T40, T41 and T42 series laptops who need more RAM for everyday applications.

DDR memory standard limits module density

The DDR technology used in these laptops restricts the maximum capacity per slot. A single one-gigabyte module fits that ceiling, but the machine may not accept larger densities even if they physically fit.

Verify slot count and current configuration

Check how many memory slots your ThinkPad has and whether one is already occupied. Some models in the 2373, 2374, 2375, 2376, 2378 and 2379 ranges only provide a single user-accessible slot, so this upgrade would replace the existing stick.

Questions about this item

Is this the only capacity offered for these ThinkPad models?

The listing shows a single 1GB module, so there is no other capacity to choose from for the T40, T41 or T42 series.

What does the 1GB capacity mean once installed in a ThinkPad T40, T41 or T42?

Adding this module gives the notebook a total of 1GB of system memory, which is the maximum addressable amount for these Pentium M platforms.

Which memory interface does this upgrade use and what does it limit in practice?

The module fits the DDR SO-DIMM slot used by the T40, T41 and T42, capping the system at the 1GB capacity this stick provides.
