16 GB DDR4 SODIMM for Tecra X40

This 16 GB DDR4 2400 MHz SODIMM module is built for Toshiba Tecra X40-00K, X40-01D, X40-01E, X40-D-10Z and X40-E Series laptops. It delivers a straightforward memory upgrade for owners of those specific models who need more capacity for everyday workloads.

Before ordering

Verify that your Tecra X40 variant appears in the supported list and that a free 260-pin DDR4 slot is available. The system maximum is 32 GB across two sockets, so this single 16 GB stick fits either as a first module or as an addition to an existing 16 GB stick. Non-ECC unbuffered operation is required; ECC or registered modules will not work.

Thermals and power

The module runs at the standard DDR4 voltage of 1.2 V and has no heat spreader, relying on the laptop's internal airflow for cooling. Passive operation means no fan noise is added. Power draw remains low during typical office and multitasking use, matching the platform's original memory specification.
