Laptop DDR4 SO-DIMM kit

This Crucial kit supplies 16 GB of DDR4 memory in two 8 GB SO-DIMM modules. It targets notebook owners who want a straightforward capacity increase without ECC or registered buffering. The 260-pin form factor fits standard laptop slots that accept DDR4 2133 MT/s memory.

Fits 260-pin DDR4 slots

Each module runs at 1.20 V and uses the industry-standard 260-pin SO-DIMM layout. The unbuffered design works with consumer notebook platforms that support DDR4 2133 speeds. No heat spreader is fitted, so the modules sit low in tight chassis clearance.

16 GB at CL15 latency

The pair delivers 16 GB total capacity with a CAS latency of 15 cycles at 2133 MT/s. This headroom handles everyday multitasking and typical productivity workloads. Systems needing ECC protection, higher frequencies or larger single-module densities will not be served by this kit.

Questions about this item

Will the 1.20 V DDR4 2133 modules throttle under sustained load without a heat spreader?

The kit runs at the standard 1.20 V with no heat spreader; laptop SO-DIMM slots rely on chassis airflow, so throttling is unlikely at the rated 2133 MT/s CL15 speed.

How much heat or noise do the two 8 GB sticks add during all-day use?

Unbuffered DDR4 at 1.20 V produces minimal heat and zero noise; the modules add negligible thermal load to a normal laptop cooling system.

My laptop has 260-pin DDR4 SO-DIMM slots — is that the only requirement for this kit to work?

Yes, the kit uses 260-pin DDR4 SO-DIMM form factor at 2133 MT/s CL15; the system must support DDR4 SO-DIMM memory at that speed and voltage.
