Targeted DDR4 SODIMM for HP ZBook

This 8GB DDR4 module is built specifically for HP ZBook 14u G5, 14u G6, 15 G4, 15u G5 and 17 G4 mobile workstations. It suits professionals who need a straightforward capacity increase for multitasking and larger datasets on these supported platforms. The non-ECC unbuffered design matches the original system requirements exactly. Buyers with other laptop models or desktop motherboards cannot use this module.

Installing the 260-pin SO-DIMM

Installation follows the standard SODIMM process: power off, remove the access panel, align the notch and press until the clips lock. The 1.2V JEDEC voltage means no BIOS voltage adjustments are required. The most common issue is inserting the stick at the wrong angle, which prevents the retention clips from engaging fully. Systems that already populate every slot will need an existing module removed before this one can be added.

DDR4 2400MHz practical limits

The module runs at 2400MHz with CL17 timings and is backward compatible with 2133MHz operation if the platform requires it. Bandwidth is capped by the PC4-19200 specification, so workloads that demand higher throughput will not benefit from faster memory kits. The single-rank 1Rx8 organisation works within the memory controller limits of the listed ZBook models. Applications needing ECC error correction or registered buffering are not supported by this stick.

Questions about this item

How can I confirm the OWC 8GB DDR4 2400MHz module is running correctly after installing it in my HP ZBook 15u G5?

Enter the BIOS or UEFI setup on boot and verify the memory shows 8GB at 2400MHz with CL17 timings at 1.2V; Windows Task Manager or macOS System Report will also display the same speed and capacity.

What comes in the box with the OWC 2S4D41R808GB SODIMM and is anything else required for installation in a ZBook 14u G6?

The package contains the single 8GB 260-pin DDR4 SODIMM module only; no tools, screws or additional cables are included or needed for the memory slot.

Which OWC DDR4 SODIMM variant matches a ZBook 15 G4 that needs a PC4-19200 CL17 1.2V stick?

This 8GB 260-pin DDR4 2400MHz CL17 1.2V Non-ECC SODIMM (part 2S4D41R808GB) is the specified match for that model.
