HP Envy 27 SODIMM upgrade

This OWC 4GB DDR4 module is built for the HP Envy 27 all-in-one models listed in the specifications. It suits owners who want a straightforward capacity increase for everyday multitasking and general productivity.

Before ordering

Verify that your Envy 27 unit uses a 260-pin DDR4 SODIMM slot and accepts non-ECC unbuffered memory running at 1.2V. The supported models are 27-b101la, 27-B101NF, 27-b101nl, 27-b101no and 27-b105na. Confirm the existing stick matches the PC4-17000 2133MHz CL15 rating.

Sustained workload behaviour

The module operates at the standard 1.2V JEDEC voltage without a heat spreader, so thermal performance depends on the chassis airflow. Under continuous load it maintains the rated 2133MHz speed and CL15 latency as validated by OWC lab testing.
