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.

Questions about this item

How can I confirm the 16GB DDR4 2133MHz SO-DIMM is recognised correctly after installation?

Open Task Manager or BIOS and verify the new module shows 16 GB at 2133 MHz with CL15 timings and 1.2 V operation.

What is included in the package and what else is needed for the HP ZBook 15u G3?

The box contains one 16 GB 260-pin DDR4 SO-DIMM stick; no extra parts are required if a free slot exists.

Should I choose the single 16GB stick or add a second to reach the 32GB maximum on my ZBook 15u G3?

One 16 GB module works immediately; adding a second identical stick later doubles capacity to the 32 GB limit across the two sockets.
