OWC 4GB DDR4 SODIMM for HP ZBook

This 4GB DDR4 module is built for HP ZBook 14u G5, 14u G6, 15 G4, 15u G5 and 17 G4 workstations. It suits professionals who need a straightforward memory increase for daily productivity tasks. The 260-pin SODIMM fits the factory slot without adapters or configuration changes. Installation follows the standard laptop memory procedure.

4GB capacity and DDR4 2400 speed

The single 4GB rank delivers 19200 MB/s bandwidth at CL17 latency. It handles typical office workloads, web browsing and light content creation with adequate headroom. Larger datasets, virtual machines or heavy multitasking will exhaust the available capacity quickly. The module is unbuffered and non-ECC, matching the platform requirements exactly.

Low-voltage operation at 1.2V

Standard 1.2V DDR4 voltage keeps power draw minimal inside the slim ZBook chassis. No heat spreader is fitted, relying on the laptop's existing thermal solution for passive cooling. The module runs silently with no moving parts and adds negligible thermal load. JEDEC compliance ensures stable operation within the system's designed power envelope.

Questions about this item

Will the 4 GB DDR4 2400 MHz CL17 1.2 V SODIMM run with the original memory in my HP ZBook 15 G4?

Yes, it is designed for that model and matches the DDR4 2400 MHz PC4-19200 CL17 1.2 V specification, so it will operate alongside the factory modules.

How can I verify the 260-pin DDR4 2400 MHz module is running at 2400 MHz with CL17 after I install it?

Open Task Manager or a system-information tool and confirm the memory speed shows 2400 MHz and the timings list CL17.

Does the 4 GB DDR4 2400 MHz SODIMM come with any tools or extra parts, or is it just the memory stick?

Only the SODIMM module is included; no screwdriver, thermal pad or additional components are supplied.
