16GB DDR4 2400 SODIMM upgrade

This 16GB DDR4 2400 CL17 SODIMM module is built for Toshiba Portege Z30-E series notebooks. It uses a 260-pin unbuffered non-ECC design running at 1.2V. The single stick adds 16GB of system memory to compatible models.

Suits Z30-E models with free slots

It fits Z30-E-10X, Z30-E-115, Z30-E-12M, Z30-E-138, Z30-E-13M and Z30-E-15X laptops that have an open SODIMM socket. Builders who need ECC registered memory or a different DDR generation should look at other parts.

Maximum system capacity is 32GB

The platform supports up to 32GB across two SODIMM sockets. Adding this 16GB stick moves the total toward that limit, but exceeding 32GB is not possible on these systems.

Questions about this item

What speed does the DDR4 2400 SODIMM run at in a Portege Z30-E?

The module is rated DDR4 2400 (PC4 19200) and will operate at that speed provided the CPU and chipset support it; all installed memory runs at the slowest module or processor limit.

Does the 260-pin stick fit the Z30-E SODIMM slots?

Yes, it is a 260-pin DDR4 SO-DIMM and the Z30-E has two SODIMM sockets that accept this form factor.

How do I install the 16 GB module and what step is often missed?

Power off, unplug, open the bottom cover, insert the stick at an angle until the contacts disappear, then press down until the side clips click; the step often missed is pressing firmly enough for both clips to latch.
