OWC 2S1D41R8016S 16GB (4x4GB) DDR4 2133MHz CL15 laptop RAM

SKU CH-A36J-V7Z5E

16 GB of DDR4 laptop memory in a 2133 MHz CL15 kit of four 4 GB modules for compatible notebooks and NAS units

Capacity 16GB (4 x 4GB)

  • 16 GB total capacity from four 4 GB modules
  • DDR4 2133 MHz speed with CL15 latency for responsive multitasking
  • 2 V low-voltage operation reduces power draw and heat
  • 260-pin SO-DIMM form factor fits laptops, all-in-ones and NAS systems
  • JEDEC and RoHS compliant for warranty-safe upgrades

Kit composition and target systems

This OWC kit provides 16 GB of DDR4 laptop memory arranged as four 4 GB modules. The 260-pin SO-DIMM form factor fits laptops, all-in-one PCs, mini desktops, micro servers and NAS units that accept DDR4 SO-DIMMs.

Upgrade path and value threshold

The kit replaces lower-capacity or slower DDR4 SO-DIMM sets in systems with four available slots. The jump is worthwhile when the platform supports 2133 MHz operation and the workload benefits from 16 GB total capacity in a quad-channel populated configuration.

Fit and alternatives

Buyers with four-slot DDR4 laptops, compact desktops or NAS devices needing a 16 GB quad-module kit at CL15 1.2 V will find this a direct match. Systems limited to two SO-DIMM slots, those requiring ECC or registered modules, or builds needing speeds above 2133 MHz should consider other memory configurations.

Questions about this item

Will the 260-pin DDR4 SO-DIMM modules fit my laptop's memory slots?

The kit uses 260-pin DDR4 SO-DIMM form factor, which is the standard for laptops and all-in-one systems that support DDR4 memory.

Do I need to install all four 4GB modules together for dual-channel operation?

The 16GB kit is a dual-channel kit of four 4GB modules; populate matching slots on the motherboard, usually same-coloured pairs, to enable dual-channel mode.

Will the CL15 latency require any BIOS adjustment or voltage change over time?

Modules run at standard 1.2V with JEDEC CL15 timings; no BIOS tuning is needed and voltage remains fixed for the life of the memory.
