Targeted 8 GB DDR4 SODIMM for ProBook 455 G4

This module is built for owners of the HP ProBook 455 G4 who need a single 8 GB DDR4 SODIMM running at 2133 MHz. It fits the 260-pin slot and operates at 1.2 V without ECC or buffering. The CL15 timing and 2Rx8 organisation match the factory specification for that notebook.

Single-stick kit keeps the second slot free

The package contains one 8 GB stick, leaving the second SODIMM socket available for a future upgrade to the 16 GB maximum supported by the ProBook 455 G4. No heat spreader is included, so the module fits the slim chassis without clearance issues.

Straightforward slot-in installation

Align the notch with the key in the 260-pin socket, press firmly until the side clips click, then restart the laptop. The most common issue is the stick not seating fully on the first push; reseating usually resolves a blank screen or memory error.

Questions about this item

Will the 260-pin DDR4 SODIMM need any firmware updates or re-seating after installation?

The module is unbuffered and non-ECC, so it works without firmware updates; re-seating is only needed if the laptop is moved while running.

What stops me from adding a second 8 GB stick to reach the 16 GB maximum?

The ProBook 455 G4 has two SODIMM sockets and a 16 GB limit, so a second identical 8 GB module fills the remaining slot.

Does the 1.2 V CL15 module run hot or loud during all-day workloads?

No heat spreader is fitted, but DDR4 at 1.2 V produces minimal heat and the laptop’s fan profile handles it silently.
