ThinkPad DDR4 3200 SoDIMM

This Lenovo ThinkPad module adds 8 GB of DDR4 memory running at 3200 MHz to compatible laptops. It uses the standard 260-pin SO-DIMM form factor and carries CAS latency CL3. The upgrade targets users who need more headroom for multitasking or memory-hungry applications on supported ThinkPad models.

Slot, generation and maximum capacity

Verify that your laptop accepts DDR4 SO-DIMM modules and has a free 260-pin slot before ordering. Check the system manual or manufacturer specification for the maximum supported memory per slot and total capacity. The module is OS independent, but the platform must be designed for DDR4 at 3200 MHz to operate at the rated speed.

Thermals, acoustics and power

SO-DIMM memory has no moving parts and produces no audible noise during operation. Heat output is minimal and handled passively through the module’s PCB and the laptop’s existing thermal solution. Power draw follows the standard DDR4 1.2 V specification, adding only a small load to the system’s memory rail.

Questions about this item

What comes in the box with the Lenovo 4X71D09533 SoDIMM and do I need any extra parts to install it?

The module is supplied as a single 260-pin DDR4 SoDIMM; no additional components are required for installation in a compatible laptop slot.

Should I choose the 8 GB 3200 MHz version or a different capacity for my ThinkPad upgrade?

This part number provides exactly 8 GB at 3200 MHz; select it when your service manual lists 4X71D09533 as the approved upgrade for your model.

How does the 3200 MHz speed rating affect real-world performance once the module is seated in my laptop?

The memory will run at up to 3200 MHz if the platform supports that data rate, otherwise it downclocks to the highest speed the system allows.
