8GB DDR4 SO-DIMM for Tecra Laptops

This Computer Memory Solutions module delivers 8GB of DDR4 2400 memory in a 260-pin SO-DIMM form factor. It operates at 1.2V with CL17 timing and uses unbuffered, non-ECC chips. The stick is validated for Toshiba Tecra A40-D, A50-E and C50-D models.

Suits single-slot upgrades on listed Tecra models

Owners of the named Tecra notebooks who need an 8GB module for an empty slot or a direct replacement will find this part matched to their system. Builders working on other laptop lines or desktop boards should look elsewhere, as the 260-pin SO-DIMM layout and DDR4 2400 specification are not interchangeable with those platforms.

Verify slot count and maximum memory before ordering

The compatible Tecra systems support up to 32GB across two SO-DIMM sockets. Confirm your laptop has a free 260-pin slot and that adding this 8GB stick will not exceed the 32GB ceiling. Also check that the existing memory runs at DDR4 2400 so the new module can operate at its rated speed.

Questions about this item

What slot type does the Tecra A40-D, A50-E or C50-D need for this 260-pin DDR4 SO-DIMM?

The laptop must provide a DDR4 SO-DIMM slot; the module is a 260-pin unbuffered non-ECC stick that fits that socket.

Will this CL17 2400 MHz module run with existing CL15 DDR4 memory in the second slot?

Yes, the system will operate both modules at the slower CL17 timing while keeping the 2400 MHz speed.

How can I confirm the 8 GB stick is recognised at 2400 MHz after installation?

Open Task Manager or BIOS and verify the installed memory shows 8 GB running at 2400 MHz with CL17 timings.
