8GB DDR4 3200 SODIMM for HP EliteBooks

This 8GB DDR4 3200MHz CL22 SODIMM upgrades HP EliteBook 840 G8, 845 G7, 845 G8, 850 G8 and 855 G7 laptops. It runs at 1.2V, uses a 260-pin unbuffered layout and meets JEDEC PC4-25600 specifications. The module is a non-ECC 1Rx8 design without a heat spreader.

Fits listed EliteBooks only

The part is validated for the five EliteBook models named above. It will not work in systems that require ECC registered memory, a different pin count, another DDR generation or a higher voltage. Buyers with other laptops should verify their exact model and memory requirements first.

8GB single-module capacity

The stick provides exactly 8GB in one 1Rx8 module. If the target laptop needs a larger total capacity or a matched pair for dual-channel operation, additional modules of the same specification must be sourced.

Questions about this item

What laptop models must I already own for this OWC 8GB DDR4 3200MHz CL22 1.2V 260pin SODIMM to work?

This module is validated for HP EliteBook 840 G8, 845 G7, 845 G8, 850 G8 and 855 G7; your system must be one of those models with a free 260-pin DDR4 SODIMM slot.

How does this CL22 3200MHz module behave alongside the factory memory already in my EliteBook?

The JEDEC-standard DDR4 3200 PC4-25600 timing lets it run at the same speed and voltage as the original sticks; the system will operate all channels at the lowest common frequency and tightest latency.

How can I confirm the 8GB upgrade is running at 3200 MT/s after installation?

Open Task Manager’s Performance tab and check the reported speed; it should read 3200 MT/s for the new module.
