16GB DDR4 2133 SODIMM for laptops and NAS

This 16GB DDR4 2133 CL15 module uses the 260-pin SODIMM form factor and runs at 1.2V. It is built for laptops, all-in-one systems and NAS devices that accept DDR4 SO-DIMM memory. The unbuffered non-ECC design matches standard consumer platforms.

Fits DDR4 SO-DIMM slots without extra hardware

The stick plugs directly into a 260-pin DDR4 SO-DIMM socket and requires no heat spreader or additional cooling. It draws 1.2V from the slot, leaving headroom for other components. Installation is a tool-free DIY step in most supported chassis.

Replaces 8GB or 4GB DDR4 2133 modules

Upgrading from lower-capacity DDR4 2133 CL15 sticks adds 16GB in a single slot, which helps when the system has only one socket. The jump is worthwhile when multitasking or large-file workloads exceed the current memory ceiling. Builders needing ECC or registered memory cannot use this module.

Questions about this item

What is the CAS latency of this DDR4 2133 SODIMM?

The module runs at CL15 latency, which is the standard timing for JEDEC DDR4 2133 memory.

How much power does the 1.2 V module draw during continuous operation?

It operates at the JEDEC standard 1.2 V, so power draw stays low and heat output is minimal without a heat spreader.

Which slot type must my laptop or NAS have for this upgrade?

The system needs a 260-pin DDR4 SO-DIMM slot; the module is unbuffered and non-ECC.
