Server ECC Registered RDIMM

This 16GB DDR4 module runs at 3200MHz with CL22 latency and 1.2V operation. It uses a 288-pin 2Rx8 registered design with ECC for error correction. The part matches Samsung M393A2K43DB2-CWE, M393A2K43DB3-CWE and M393A2K43EB3-CWE specifications. It is built for workstations and servers only.

Sustained load stability

Registered buffering and ECC protect data integrity during continuous operation. The module meets JEDEC PC4-25600 standards for consistent throughput. Testing follows OEM specifications to maintain reliability under extended workloads. Mixing with unbuffered memory is not supported.

Build and daily use

The module has no heat spreader, keeping the profile low for dense server slots. RoHS compliance and JEDEC compliance ensure a warranty-safe upgrade. Identical capacity, speed and manufacturer across all DIMMs are recommended for optimal performance. OWC provides a limited lifetime warranty with free tech support.

Questions sur cet article

Does the 1.2 V rating and 2Rx8 organisation keep this module cool and efficient during continuous server workloads?

The module runs at the standard DDR4 1.2 V and uses a 2Rx8 registered layout, which together limit power draw and heat output during sustained operation.

What motherboard features are required for this 288-pin DDR4 3200 ECC registered RDIMM to function?

The system must provide DDR4 RDIMM slots that support ECC registered memory at 3200 MT/s (PC4-25600) and accept 2Rx8 modules.

Can I mix this 3200 CL22 stick with slower DDR4 registered ECC modules already installed in my server?

The module is rated at DDR4 3200 CL22; when mixed with slower registered ECC DIMMs the memory controller will downclock all sticks to the lowest common speed.
