16GB DDR3 SODIMM for ThinkPad X250

This 16GB DDR3 1600MHz SODIMM module is built specifically for the Lenovo ThinkPad X250 laptop. It arrives as a single 16GB stick using 204-pin unbuffered non-ECC memory. The CL11 timing and 1.5V voltage match the platform requirements. Computer Memory Solutions validates compatibility for this exact model.

Suitable for single-slot 16GB upgrades

This module suits owners of a ThinkPad X250 who need the maximum 16GB capacity in the sole memory slot. It is not for systems requiring DDR4 memory, ECC registered DIMMs, or 288-pin desktop form factors. Buyers with laptops limited to 8GB maximum capacity or different pin counts should look elsewhere.

Single 16GB stick fills the only slot

The X250 provides one SODIMM socket with a 16GB ceiling, so this single 2Rx8 rank module delivers the full supported capacity in one installation. No second module can be added. The 1600MHz PC3-12800 speed rating aligns with the platform specification.

Questions about this item

Does the ThinkPad X250 need a specific BIOS version before I install this 16 GB DDR3 1600 SODIMM?

The module is built to the standard 204-pin DDR3 1600 PC3-12800 specification with CL11 timing and 1.5 V operation, so it works with the X250's native memory controller without a BIOS update.

Can I keep the original 4 GB stick and add this 16 GB module for 20 GB total?

The X250 has only one SODIMM socket and a 16 GB maximum, so the original stick must be removed; this single 16 GB module fills the slot and reaches the platform limit.

How do I confirm the new memory is running at 1600 MHz with CL11 after installation?

Open Task Manager's Performance tab or run CPU-Z; both will show 1600 MHz DDR3 speed and 11-11-11 timings when the module is seated correctly.
