Samsung - DDR4 - module - 32 GB - DIMM 288-PIN - 2933 MHz / PC4-23400 CL21 1.2 V registered ECC

The Samsung M393A4K40CB2-CVF is a 32GB DDR4 RDIMM memory module for PCs and servers, operating at 2933 MHz with a CAS latency of 21. It uses ECC (Error-Correcting Code) to detect and correct single-bit memory errors, improving stability and reliability for critical workloads while maintaining low power consumption at 1.2 V.

Advantages

The module offers a high single-module capacity of 32 GB in a DDR4 RDIMM form factor, ECC support for error correction, and a 2933 MHz clock speed that balances performance and power efficiency. Its design is intended to provide stable operation under sustained loads and compatibility with systems that require registered memory.

Suitable for

• Servers and workstations requiring registered ECC memory
• Database and virtualization workloads
• Compute-intensive applications and multi-user environments

Key specifications

• Capacity: 32 GB
• Type: DDR4 RDIMM
• Speed: 2933 MHz
• CAS Latency: 21
• Voltage: 1.2 V
• Model: M393A4K40CB2-CVF
• ECC: Yes (registered, error-correcting)

How to use

Install the RDIMM module into a compatible server or workstation motherboard that supports DDR4 registered ECC memory. Power down the system, discharge static electricity, and insert the module into the appropriate DIMM slot until the retention clips engage. After installation, power on the system and verify that the BIOS/UEFI recognizes the new 32 GB module and that ECC is enabled if applicable.

Recommendations

Use this Samsung DDR4 32GB 2933MHz ECC RDIMM in systems that explicitly support registered ECC DDR4 modules. For optimal stability, pair modules according to the motherboard/vendor memory population guidelines and ensure firmware/BIOS is up to date.
