SAMSUNG M471A2K43BB1-CPB 16GB DDR4-2133 SO-DIMM laptop RAM

16 GB DDR4-2133 SO-DIMM module

This Samsung laptop memory module provides 16 GB of DDR4 capacity in a single SO-DIMM stick. It is designed for notebooks and small-form-factor systems that accept DDR4 SO-DIMM memory. The module suits users upgrading a compatible slot or replacing a failed stick.

DDR4-2133 speed ceiling

The memory operates at 2133 MT/s, which is the baseline DDR4 data rate. Systems that only support this speed will run the module at its rated frequency, while platforms capable of higher DDR4 speeds will downclock it to 2133 MT/s. Bandwidth is therefore limited to the PC4-17000 specification.

CL15 latency timing

The module carries a CAS latency of CL15 at 2133 MT/s. This timing determines how quickly the memory responds to read requests and is the primary specification that defines whether the stick matches the platform’s supported latency profile.
