SAMSUNG M393A4K40CB2-CVF 32 GB DDR4 2933 MHz ECC Registered DIMM desktop RAM

SKU CH-K9VJ-X5M67 MPN M393A4K40CB2-CVF

A 32 GB DDR4 registered ECC DIMM running at 2933 MHz with CL21 latency and 1.20 V operation

  • 32 GB capacity supports demanding server workloads
  • DDR4-2933 speed delivers 23466 MB/s bandwidth
  • ECC registered design corrects data errors automatically
  • CL21 latency keeps response times predictable
  • 20 V operation reduces power draw per module

Server-grade capacity

This 32 GB DDR4 module is built for server platforms that require registered memory with error correction. The dual-rank design and ECC support make it suitable for workloads where data integrity is critical.

Registered signal and 288-pin DIMM form factor

The module uses registered signal processing to reduce electrical load on the memory controller, allowing larger memory configurations. It fits standard 288-pin DDR4 DIMM slots and operates at the DDR4-2933 standard.

Sustained operation at 1.20 V and CL21

Rated for continuous use at 1.20 V with a CAS latency of 21 cycles, the module maintains stability under prolonged server workloads without relying on short burst performance.

Preguntas sobre este artículo

How does the 1.20 V voltage affect sustained operation?

The module runs at a standard 1.20 V DDR4 voltage, keeping power draw and heat output low during continuous server workloads.

What noise or heat should I expect when this DIMM runs all day?

As a passive component with no moving parts, the registered DIMM produces no audible noise and minimal heat at 1.20 V.

Which motherboard slot and chipset features are required for this 288-pin registered ECC module?

A DDR4 RDIMM slot supporting ECC and registered signal processing is needed; the 288-pin form factor fits standard server boards.
