8GB DDR3L SODIMM for ThinkPad

This 8GB DDR3L SODIMM runs at 1600 MHz with CL11 latency and 1.35V operation. It targets owners of Lenovo ThinkPad P50s, S431, S440, S531, S540 and T440 models who need a single-module capacity increase.

204-pin unbuffered non-ECC layout

The module uses a standard 204-pin SO-DIMM edge connector and 2Rx8 organisation without a heat spreader. JEDEC and RoHS compliance means it fits the factory slot and meets OEM electrical requirements for warranty-safe upgrades.

Low-voltage DDR3L thermals

Operating at 1.35V reduces power draw and heat output compared with standard DDR3, helping the laptop's existing cooling cope with the extra capacity. No active cooling is required on the module itself.

Perguntas sobre este artigo

What bandwidth does the DDR3L 1600 PC3L-12800 interface deliver?

The DDR3L 1600 PC3L-12800 standard provides a peak transfer rate of 12800 MB/s at 1600 MHz.

Does the 204-pin SODIMM fit the memory slot in a ThinkPad T440?

Yes, the 204-pin SODIMM form factor matches the DDR3L slot used in the ThinkPad T440 and the other listed models.

How do I install the module, and what step is often missed?

Power off the laptop, remove the bottom cover, insert the SODIMM at an angle until the gold contacts disappear, then press down until the side clips click — skipping the click leaves the module loose.
