16GB DDR4 2400 ECC Registered module

This 16GB DDR4 2400 module is built for servers and workstations that require error-correcting registered memory. It operates at PC4 19200 with a CAS latency of CL17 and a voltage of 1.20V. The 2Rx8 organisation suits multi-channel configurations on compatible platforms.

Installation notes

The 288-pin DDR4 form factor fits standard registered DIMM slots on qualified server boards. Alignment notches prevent incorrect insertion, but the module will not work in consumer boards that lack registered memory support. Mixing registered and unbuffered DIMMs or combining different ranks can prevent the system from posting.

ECC Registered specification

Error-correcting code and registered buffering are the defining features that determine compatibility with your server platform. This module provides both, making it suitable for systems that mandate ECC Registered memory. It will not function in desktops or laptops that require unbuffered non-ECC DIMMs.

Questions about this item

How can I confirm the module is running at DDR4 2400 with CL17 after installation?

Check the BIOS or a tool like CPU-Z; it should report 2400 MT/s, PC4 19200 bandwidth and CAS latency 17 at 1.20 V.

What ships with the M393A2K43BB1-CRC and what must I source separately?

The box contains the 16 GB 288-pin RDIMM only; no heat spreader or extra cables are included.

Which capacity and rank option should I pick for a dual-channel server board?

This SKU is a single 16 GB 2Rx8 module; add a second identical stick to populate both channels.
