16GB DDR4 3200 Replacement Module

This 16GB DDR4 DIMM runs at 3200MHz with a CAS latency of CL22 and operates at the standard 1.20V. It is built as an unbuffered, non-ECC module using Samsung chipset components and is designed to replace Samsung M378A2G43BB3-CWE and M378A2G43CB3-CWE modules in desktop systems.

Suitable for Samsung DDR4 Upgrades

The module suits owners of desktops that originally shipped with the listed Samsung part numbers and need a direct 16GB replacement. It is not intended for systems requiring ECC or registered memory, nor for platforms limited to lower DDR4 speeds or different form factors such as SO-DIMM.

Standard 288-Pin Desktop Installation

Installation follows the usual 288-pin DIMM procedure: align the notch, press firmly until the retention clips engage, then verify the 3200MHz speed in BIOS. Common issues include the system defaulting to a lower JEDEC speed if XMP is not enabled or if the motherboard does not support the rated frequency.

Questions about this item

What desktop motherboard slot does this 288-pin DDR4 DIMM require?

This module fits a standard DDR4 DIMM slot on a desktop motherboard; ensure your board supports DDR4 memory before installing.

Will this 3200 MHz CL22 module run with older DDR4 sticks rated at lower speeds?

Yes, the memory will downclock to match the slowest installed module so mixed-speed DDR4 kits can operate together.

How can I confirm the module is running at its rated 3200 MT/s after installation?

Open the system BIOS or a hardware utility such as CPU-Z and check that the reported DRAM frequency shows 3200 MT/s.
