SAMSUNG M393A4K40BB0-CPB0 32GB DDR4 2133 Registered server RAM

32 GB registered DDR4 for servers

This module delivers 32 GB of DDR4 2133 memory in a registered design. It targets servers and workstations that require error-correcting capacity with 2Rx4 organisation. The 288-pin form factor fits standard DDR4 slots. Systems needing unbuffered memory or higher speeds should look elsewhere.

Thermals and power at 1.20 V

Operating at 1.20 V keeps power draw modest for a 32 GB registered stick. No heat spreader is fitted, so airflow across the PCB handles cooling. The CL15 latency at 2133 MT/s produces predictable thermal output under sustained loads. Acoustic impact depends entirely on the chassis fans.

Registered design and 2Rx4 layout

The registered buffer reduces electrical load on the memory controller, enabling larger total capacities per channel. The 2Rx4 organisation increases density without adding ranks beyond what the platform expects. No software or accessories are bundled; the module itself provides the registered and density benefits.
