Computer Memory Solutions 16GB DDR4 2133MHz SO-DIMM memory upgrade

Targeted 16 GB DDR4 SO-DIMM

This 16 GB DDR4 2133 MHz module is built for the HP ZBook 15u G3 mobile workstation. It suits owners of that laptop who need the maximum single-stick capacity the platform accepts. The kit contains one 260-pin SO-DIMM rated at PC4 17000 with CL15 timings. Buyers who want more storage or a different form factor should look elsewhere.

Straightforward laptop installation

Power off the workstation, remove the bottom cover, and insert the stick into an empty SODIMM slot at the correct angle until it clicks. The module is unbuffered, non-ECC and runs at 1.2 V, matching the factory specification. No heat spreader is fitted, so clearance is minimal. The most common issue is seating the module incompletely, which causes the system to show less memory than installed.

Verify slot count and current layout

The ZBook 15u G3 supports up to 32 GB across two SODIMM sockets. Confirm how many slots your unit has populated before ordering. If both slots are already filled, a single 16 GB stick will not increase total capacity unless you remove an existing module. Check the installed memory configuration in the BIOS or operating system first.
