System-specific DDR4 upgrade

This 16 GB DDR4 SODIMM is built for the HP EliteBook 855 G8 and other laptops that accept 260-pin unbuffered non-ECC memory. It delivers a straightforward capacity increase for professionals who need more headroom for everyday workloads.

16 GB at 3200 MHz CL22

The module runs at DDR4 3200 (PC4-25600) with a CAS latency of 22 and a standard 1.2 V supply. It handles multitasking, larger documents and multiple browser tabs comfortably, while very heavy rendering or virtualisation workloads may still benefit from additional capacity.

JEDEC compliant 2Rx8 design

The dual-rank 2Rx8 organisation meets JEDEC and RoHS specifications without a heat spreader, keeping the profile low for tight laptop slots. Gold-edge 260-pin connectors ensure reliable seating during DIY installation, and the module is validated for warranty-safe upgrades.

Questions about this item

Will the 3200MHz CL22 SODIMM run at the correct speed alongside my existing DDR4 module in the HP EliteBook 855 G8?

The module operates at DDR4 3200 (PC4-25600) with CL22 latency and 1.2V. JEDEC compliance allows it to downclock automatically to match slower installed memory for stable dual-channel operation.

How can I verify the 16GB DDR4 3200MHz SODIMM is detected correctly after installing it in my HP EliteBook 855 G8?

Open Windows Task Manager or BIOS/UEFI and confirm 16GB total capacity, DDR4 type, 3200MHz speed, and 2Rx8 rank. The OWC label shows part number 3S2D42R816GB for physical verification.

Does the OWC 3S2D42R816GB SODIMM include any tools or adapters for installation in the HP EliteBook 855 G8?

The box contains only the 260-pin DDR4 SODIMM module. No screwdriver, spudger, or adapter is included. The EliteBook 855 G8 requires a standard Phillips screwdriver to access the memory slot.
