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.

Questions about this item

Does the 4 GB SODIMM ship alone, or are tools and extra parts included?

The module arrives as a single 260-pin DDR4 stick; no screwdriver, thermal pad or additional hardware is supplied.

Should I choose the 2133 MHz CL15 version or look for a different speed for my HP Envy 27?

This 2133 MHz CL15 1.2 V part matches the JEDEC spec for the listed Envy 27 models; faster or slower modules are not required.

What does the PC4-17000 rating mean once the RAM is installed in the Envy 27?

It confirms 2133 MT/s bandwidth at CL15 latency, giving the all-in-one the standard DDR4 throughput the platform expects.
