The Samsung M378A4G43AB2-CWE is a 32GB DDR4 UDIMM desktop memory module rated at 3200MT/s from a 1600M Hz base clock. It is a dual-rank 2Rx8 module built on A-die, with a component composition of sixteen 2G by 8-bit DRAM devices, and operates at 1.2V. The M378A4G43AB2-CWE uses the standard 288-pin unbuffered DIMM edge connector. Samsung supplies the module in trays of 25 units.

An unbuffered DIMM is the memory type used by desktops and entry-level servers, where the DRAM devices connect directly to the memory controller without the register found on an RDIMM, so it is the correct module for consumer and workstation-class platforms rather than for high-capacity server boards. At 32GB per module the M378A4G43AB2-CWE is a high-density DDR4 UDIMM, letting a four-slot desktop or workstation reach 128GB for virtualisation, engineering simulation, video editing, CAD and software build workloads. DDR4 at 3200MT/s is the top standard JEDEC speed grade for the generation, and Samsung A-die is well regarded for stability at that rating. Buyers are system builders, workstation integrators and IT departments upgrading or sustaining DDR4 platforms as the installed base ages and new supply shifts to DDR5.
