SAMSUNG M393A4K40BB0-CPB 32GB DDR4-2133 2Rx4 LP ECC REG server RAM

32 GB DDR4-2133 ECC Registered DIMM

This 32 GB DDR4-2133 module delivers error-correcting, registered memory for server platforms that require data integrity. It operates at 1.20 V with a CAS latency of CL15 and is organised as a dual-rank 2Rx4 configuration. The 288-pin DIMM targets enterprise workloads where stability outweighs raw frequency.

Low-profile installation in dense chassis

The low-profile height allows the stick to fit in 1U and blade systems where vertical clearance is tight. Alignment follows the standard 288-pin DDR4 keying; the module seats with even pressure until the retention clips engage. A common issue arises when the platform BIOS defaults to a higher voltage or disables ECC, preventing the system from posting.

Steady throughput under continuous load

Registered signalling reduces electrical load on the memory controller, helping sustain bandwidth during extended compute jobs. ECC detection and correction maintain data accuracy without halting the pipeline when single-bit errors occur. The CL15 timing at 2133 MHz provides predictable latency for virtualization and database tasks that run for hours rather than seconds.
