OWC 2S1D42R808GB 8GB DDR4 2133 CL15 SODIMM memory upgrade

Targeted upgrade for specific HP Envy laptops

This 8GB DDR4 SODIMM is validated for the HP Envy 15-as004na, 15-as004ng, 15-as004no, 15-as005na and 15-as005ng models. It adds capacity to systems that currently have a single slot populated or need a matched pair for dual-channel operation. Buyers whose laptops use a different DDR generation or a 288-pin desktop form factor cannot use this module.

JEDEC-compliant 260-pin unbuffered design

The module follows the PC4-17000 standard at 1.2V with CL15 latency and a 2Rx8 rank configuration. No heat spreader is fitted, keeping the profile low enough for tight laptop chassis. The gold-edge connector slots directly into the SO-DIMM socket without tools, and the non-ECC, unbuffered architecture matches the original factory specification for these Envy models.

Low-voltage DDR4 efficiency

Operating at 1.2V, the memory draws minimal power from the system battery during normal workloads. The absence of a heat spreader indicates the ICs run within thermal limits without active cooling, so fan behaviour and acoustics remain unchanged after installation. The CL15 timing at 2133MHz delivers stable throughput for everyday multitasking and larger file handling.
