Capacity & Purpose

This kit delivers 128GB of DDR4 laptop memory across eight 16GB modules. It targets users who need maximum capacity in compatible notebooks, all-in-one PCs, mini desktops, micro servers or NAS appliances.

Build Integration

The 260-pin SO-DIMM form factor fits standard DDR4 laptop slots and operates at 1.2V without a heat spreader. Unbuffered, non-ECC modules keep installation straightforward for DIY upgrades in space-constrained systems.

Sustained Behaviour

Rated at 2133MHz with CL15 latency, the modules maintain JEDEC-standard timing under continuous workloads. Dual-rank organisation on each stick supports stable throughput during extended multitasking or file-heavy sessions.

Questions about this item

Will the 2133MHz CL15 timing hold under sustained heavy workloads?

The modules run at JEDEC-standard 2133MHz with CL15 latency; without heat spreaders they rely on the laptop chassis for cooling, so sustained performance depends on the system's thermal design.

How much heat and power do eight 16GB sticks generate at 1.2V all day?

Each module operates at 1.2V; total kit power draw scales with all eight slots populated, and heat output is managed by the host device's airflow since the sticks have no spreaders.

My laptop has four SODIMM slots — can I use this 8-module kit?

The kit contains eight 260-pin DDR4 SO-DIMMs; you need a platform with eight DDR4 SO-DIMM slots to install the full 128GB, otherwise only a subset can be fitted.
