Lenovo ThinkPad DDR3 SODIMM upgrade

This 2 GB DDR3 1600 CL11 module is built for Lenovo ThinkPad L430, T430u, X131e and X131e Chromebook systems. It adds memory capacity to supported laptops that accept 204-pin SODIMMs. The kit contains a single unbuffered non-ECC stick rated at 1.5 V.

Check slot count and maximum capacity

Verify how many SODIMM sockets your ThinkPad model provides and what total memory the platform supports. Confirm the existing modules match DDR3 1600 speed and 1.5 V voltage before adding this stick. Systems limited to lower speeds will still run the module at the highest common rate.

JEDEC standard build with no heat spreader

The module follows JEDEC and RoHS specifications and carries no heat spreader, keeping the profile low for tight laptop chassis. Gold-edge 204-pin contacts insert directly into the SODIMM slot with a firm click. The 1Rx8 organisation works in single-channel or dual-channel configurations depending on the host layout.

Questions about this item

Does the OWC 2GB DDR3 1600 SODIMM arrive as a single stick or do I need to buy anything else to install it?

The package contains one 2GB DDR3 1600 CL11 1Rx8 204-pin 1.5V SODIMM module. No extra parts or tools are required for installation in a compatible laptop.

Should I choose this 2GB CL11 module or a different capacity for my ThinkPad L430?

This specific part number 1S6D31R802GB provides a single 2GB rank. If your L430 has a free slot and supports 1600MHz DDR3, this module adds 2GB; select a higher-capacity kit only if you need more total memory.

What does the PC3-12800 1600MHz rating actually deliver once the module is seated in a ThinkPad X131e?

The module runs at DDR3 1600 with CL11 latency at 1.5V, matching the JEDEC PC3-12800 standard. The X131e memory controller will operate it at its rated 1600MHz speed, giving the full bandwidth the spec promises.
