The Samsung M324R4GA3BB0-CQK is a 32 GB DDR5 ECC UDIMM rated at 4800 MT/s (4800 MHz clock speed, 2400 MHz base clock) and operating at 1.1 V. It is a dual-rank 2Rx8 module built from Samsung B-die in a (2G x 8) x 20 composition on a 288-pin form factor, the 20-device count reflecting ECC support. M324R4GA3BB0-CQK ships in trays of 50 units.

An ECC UDIMM sits between consumer memory and server RDIMMs: it carries the extra devices needed for error correction so single-bit errors are detected and corrected, but it has no register buffering the address and command bus, which limits modules per channel and requires platform support. That combination targets machines where data integrity matters but full server memory topology does not. Typical uses are entry-level and single-socket servers, workstations for engineering and simulation, network-attached storage and edge appliances, and always-on industrial or medical compute where an uncorrected bit flip is unacceptable. DDR5-4800 is the baseline JEDEC speed grade for the generation, so this module is commonly specified for platforms validated at that rate. Buyers are typically workstation and server integrators, NAS vendors and IT teams.
