16GB DDR4 2933MHz ECC Registered RDIMM

This 16GB DDR4 2933MHz PC4-23400 module is an ECC Registered RDIMM built for servers, workstations and NAS systems. It runs at 1.2V with CL21 latency and a 2Rx8 rank configuration. The 288-pin design matches Samsung part numbers M393A2K43CB2-CVF and M393A2K43DB2-CVF.

Compatibility check before ordering

Verify that your platform requires ECC Registered memory and supports DDR4 2933MHz, 2666MHz, 2400MHz or 2133MHz operation. This module will not work in standard desktop computers that use unbuffered non-ECC DIMMs. It also cannot be mixed with unbuffered memory in the same system.

Sustained load behaviour

ECC error correction and registered signalling maintain data integrity during continuous operation in multi-socket servers and storage appliances. JEDEC-standard compliance and 1.2V operation keep thermals steady without a heat spreader. The module is tested to meet OEM specifications for long-term deployment.

Questions sur cet article

Does the module ship alone or with any accessories?

The OWC DDR4 2933 MHz ECC Registered RDIMM is supplied as a single 16 GB module. No cables, brackets or additional parts are included.

How do I know this 288-pin CL21 stick is the right capacity and speed for my server?

Match your system's requirements to the 16 GB capacity, DDR4 2933 MT/s (PC4-23400) speed, CL21 latency, 1.2 V voltage and 2Rx8 registered ECC configuration.

What happens if my board only runs memory at 2400 MHz?

The module is backward compatible with 2133, 2400 and 2666 MHz platforms and will operate at the highest speed the memory controller supports.
