Product Identity

The Lenovo 256 MB DDR2 533 MHz CL4 SODIMM is a laptop memory module designed for specific legacy ThinkPad models. It targets owners of compatible systems seeking a direct replacement or capacity increase using original specification parts.

Capacity and Headroom

At 256 MB this module handles basic operating system tasks and light applications typical of the DDR2 era. It runs out quickly when multiple programs or modern web content are open, limiting multitasking headroom on supported hardware.

Upgrade Context

This part replaces an existing DDR2 SODIMM in listed ThinkPad R52 and T43 series machines. The jump is worth it when a system has an empty slot or a smaller module installed and the user needs period-correct maximum memory for legacy software compatibility.

Perguntas sobre este artigo

Will this DDR2 533 MHz CL4 SODIMM work with the existing PC2-4200 memory in my ThinkPad R52 1846?

Yes, it matches the DDR2-533/PC2-4200 standard and CL4 latency, so it will run alongside identical modules at the same speed and timing.

How can I verify the module is detected at 533 MHz with CL4 timing after installation?

Enter the BIOS or use a system-information tool; the memory should report 256 MB, DDR2-533 (PC2-4200) and CAS latency 4.

Does the package include only the single 256 MB 200-pin SODIMM or are extra items supplied?

The box contains one 256 MB DDR2 SODIMM module; no cables, brackets or additional parts are included.
