Capacity and compatibility

This is a single 32GB DDR4 2666MHz SODIMM built for laptops and all-in-one systems that accept 260-pin unbuffered non-ECC modules. It operates at the standard 1.20V and carries a CL19 latency rating.

Sustained workload behaviour

The module uses major-brand chips tested through extended quality-assurance cycles to maintain stability during long multitasking sessions and heavy memory loads. Consistent 1.20V operation helps keep thermals predictable when the system runs at full capacity for hours.

Upgrade path and fit

It directly replaces HP part numbers 4VN08AA and 6NX83AA, delivering a full 32GB in one slot instead of smaller factory configurations. The jump is worthwhile when the platform supports a single 32GB rank and the user needs maximum capacity without adding a second module.

Questions about this item

Does the 1.20V DDR4 module run cool and quiet during all-day workloads?

Standard 1.20V DDR4 SO-DIMMs consume little power and generate minimal heat, so the 32GB stick stays cool and silent in continuous use.

My laptop only has a single DDR4 SO-DIMM slot — will this 32GB module work on its own?

Yes, the kit is a single 32GB 260-pin module, so it installs alone in one slot without needing a matched pair.

Can I pair this 2666MHz CL19 stick with an existing 8GB DDR4 module in the second slot?

The system will run both modules at the slower stick's speed and timings, so the 32GB module will downclock to match the 8GB module.
