Capacity and Compatibility

This 16 GB DDR5 SODIMM is built for HP Envy 17 models 17-cw1087nr, 17-cw1097nr, 17-da0047nr and 17-da0097nr. It matches the factory specification of 5600 MT/s, CL46 latency and 1.1 V operation. The single-rank 1Rx8 module installs in the existing 262-pin slot without BIOS changes. Laptop owners who need more memory for everyday workloads can add this stick with confidence.

Sustained Workload Behaviour

JEDEC-standard timings and voltage keep the module stable during long sessions of browsing, office apps and media playback. The unbuffered non-ECC design delivers consistent throughput without the overhead of registered memory. Heat spreader is not fitted, so airflow in the chassis handles thermal load. Users running virtual machines or large spreadsheets will see steadier performance than with a mismatched slower stick.

Upgrade Context

This part replaces HP part number 79U71AA and adds 16 GB in a single slot. The jump is worth it when the system currently runs 8 GB or a lower-speed DDR5 module and the workload regularly hits the memory ceiling. It is not for buyers who need ECC error correction, registered buffering or a dual-rank configuration for specific platform requirements.

Questions about this item

How much heat does the 1.1V DDR5 SODIMM generate when the laptop runs all day?

The module operates at the standard JEDEC 1.1 V and has no heat spreader, so it relies on the laptop's own airflow; under typical workloads it adds only a small amount of warmth inside the chassis.

What must my HP Envy 17 already have for this 262-pin DDR5 stick to work?

The notebook needs a free DDR5 SODIMM slot and a BIOS that supports 5600 MT/s PC5-44800 CL46 memory; the four listed Envy 17 models meet those requirements.

Will this 16 GB DDR5 module run correctly alongside the original memory in my HP Envy 17-cw1087nr?

Yes, it is tested to match the OEM spec for that model, so it will run at the same 5600 MT/s speed and 1.1 V voltage as the factory-installed RAM.
