8GB DDR4 2133 SODIMM for laptop upgrades

This 8GB DDR4 module runs at 2133 MHz with CL15 latency and 1.20V voltage. The 260-pin SO-DIMM form factor fits standard laptop memory slots. It is unbuffered and non-ECC, matching the specifications of Samsung M471A1K43BB0-CPB, M471A1K43BB1-CPB, and M471A1K43CB1-CPB modules.

Direct replacement for specific Samsung part numbers

The module is validated as a compatible equivalent for three Samsung reference parts. Swapping the original stick with this A-Tech unit restores the same capacity, speed, and timing without requiring BIOS changes or driver installation.

DDR4 2133 interface caps bandwidth at PC4-17000

The DDR4 2133 standard limits maximum theoretical throughput to 17000 MB/s. Systems that support faster DDR4 speeds will downclock this module to 2133 MHz, so total memory bandwidth cannot exceed the PC4-17000 ceiling.

Questions about this item

Will the CL15 timing need adjustment after months of use?

The module runs at CL15 from the factory and does not require timing changes during its service life.

What limits sustained throughput on this 2133 MHz stick?

The DDR4 2133 bus and CL15 latency set the maximum sustained data rate.

How much heat and power does the 1.20 V module produce all day?

At 1.20 V the SO-DIMM draws minimal power and generates little heat during continuous operation.
