8GB DDR4 2133MHz SODIMM module upgrades HP Envy 15-as series laptops with CL15 timing and 1.2V operation

  • Total capacity8 GB
  • Rated speedDDR4 2133 (PC4 17000)
  • CAS latencyCL15
  • Rated voltage1.2 V
  • Buffer typeUnbuffered
  • Memory rank2Rx8
  • Boosts responsiveness with 8 GB DDR4 capacity
  • Runs at 2133 MHz CL15 for smooth multitasking
  • Low 1.2 V operation reduces power draw
  • 260-pin SODIMM fits listed HP Envy models
  • JEDEC and RoHS compliant for warranty-safe 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.

Questions about this item

What speed does the PC4-17000 rating actually deliver?

The PC4-17000 rating means the module runs at 2133 MHz DDR4 with CL15 latency at 1.2 V.

Will this 260-pin SODIMM fit my HP Envy 15-as series laptop?

Yes, the 260-pin DDR4 SODIMM form factor matches the memory slots in the HP Envy 15-as004na, 15-as004ng, 15-as004no, 15-as005na and 15-as005ng.

What is the correct way to seat the module so it locks in place?

Align the notch with the slot key, insert at a slight angle, then press down firmly until both side clips click — the step many miss is pushing straight down after the angle, not just pressing the edges.
