Targeted laptop upgrade

This OWC SODIMM is built specifically for the HP Envy 15-as004 and 15-as005 series. It adds 4GB of DDR4 memory running at 2133MHz with CL15 latency. The 260-pin unbuffered module operates at the standard 1.2V. It is intended for owners of those exact models who need more system memory.

Replaces factory modules

The stick upgrades the original memory installed in the compatible Envy notebooks. A jump is worthwhile when the current configuration leaves too little headroom for multitasking or larger files. Systems already at the platform maximum or using a different DDR generation cannot use this module. Buyers needing ECC or registered memory must look elsewhere.

Steady workload behaviour

JEDEC compliance and 1.2V operation keep power draw and thermals consistent during extended sessions. The CL15 timing remains stable without a heat spreader under sustained load. Every unit is tested in-house to meet OEM specifications for long-term reliability. This supports smooth multitasking over hours of use.

Questions about this item

Does the 260-pin DDR4 SODIMM fit the HP Envy 15-as004na memory slot?

Yes, the module is a 260-pin DDR4 SODIMM built to JEDEC specifications for the listed HP Envy 15 models.

What is the correct way to seat the SODIMM and which step is often missed?

Insert the module at an angle, then press down firmly until both side clips click into the notches; the click is the step many skip.

Will the 4GB 1Rx8 module need any firmware updates or periodic replacement?

No firmware is required; the memory is a passive component rated for the system lifetime under normal use.
