16GB DDR4 3200 desktop module

This 16GB DDR4 DIMM is built for desktop systems that need a straightforward memory upgrade. It runs at 3200MHz with a standard 1.20V supply and uses an unbuffered, non-ECC design. The module fits 288-pin slots and is tested as a compatible replacement for the Samsung M378A2K43EB1-CWE part.

Capacity and headroom for everyday workloads

A single 16GB stick provides enough space for typical multitasking, office applications and mainstream gaming. The 2Rx8 organisation helps density, but the module will run out of headroom when workloads demand more than 16GB of physical memory or when a platform requires registered or ECC memory for stability.

DDR4 3200 interface limits

The DDR4 3200 (PC4-25600) interface caps peak transfer rate at the rated frequency and voltage. Systems that only support lower DDR4 speeds will downclock the module automatically. Platforms requiring ECC, registered DIMMs or a different DDR generation cannot use this stick.

Questions about this item

Will this DDR4 3200 module run at its rated speed alongside older DDR4 sticks I already have?

The system will run all installed modules at the speed of the slowest stick; this module is rated for DDR4 3200 (PC4-25600) at 1.20V.

How can I verify the 16GB module is operating at DDR4 3200 after installation?

Check the memory speed in your BIOS/UEFI or use a system information tool such as CPU-Z to confirm the module reports 3200 MT/s.

What comes in the box and do I need any extra parts to install this 288-pin DIMM?

The package contains one 16GB DDR4 3200 UDIMM; no additional cables, brackets or tools are required for a standard desktop motherboard slot.
