OWC 16GB DDR4 SODIMM for HP ZBook G3/G4

This 16GB DDR4 2133MHz CL15 module is built for HP ZBook 14u G4, 15 G3, 15u G3, 17 G3 and Studio G3 mobile workstations. It targets professionals who need more memory capacity for multitasking and larger project files in these specific laptops. The non-ECC unbuffered design matches the factory memory configuration exactly.

260-pin SODIMM installation and common issues

The 260-pin SODIMM form factor fits the memory slots in the listed ZBook models without tools in most cases. A frequent problem occurs when the module is not seated fully; the retaining clips must click on both sides. Another issue is mixing this CL15 1.2V stick with existing memory of different latency or voltage, which can prevent the system from booting.

DDR4 2133MHz PC4-17000 practical limits

The DDR4 2133MHz PC4-17000 interface caps transfer rates at the JEDEC standard specification for this speed grade. Latency is fixed at CL15 and voltage at 1.2V, so there is no headroom for manual overclocking or tighter timings. Total system capacity remains limited by the number of slots and the maximum memory supported by each specific ZBook model.

Questions about this item

How can I verify the 16GB DDR4 2133MHz module is running at CL15 1.2V after installation?

Enter BIOS or use a tool like CPU-Z to confirm speed shows 2133 MHz, CAS latency reads CL15 and voltage reports 1.2 V. The system should also display 16 GB total capacity without errors.

What comes with the 260-pin SODIMM and is anything else required for the HP ZBook G3/G4 upgrade?

Only the 16 GB DDR4 2133 MHz CL15 1.2 V 260-pin Non-ECC SODIMM is included. No extra cables, brackets or tools are supplied; the module installs directly into the laptop memory slot.

Which OWC part number should I choose for a 16 GB upgrade on an HP ZBook 15 G3?

Select part number 2S1D42R816GB — it is the 16 GB DDR4 2133 MHz CL15 1.2 V 260-pin SODIMM validated for HP ZBook 15 G3 and the other listed G3/G4 models.
