4GB DDR4 2400MHz ECC RDIMM Server Memory

This 4GB DDR4 2400MHz ECC RDIMM module is built for server and workstation systems that require registered memory with error correction. It operates at 1.20V with a CAS latency of 17 and uses a 1Rx8 rank configuration on a 288-pin DIMM form factor. The module serves as a compatible replacement for the Samsung M393A5143DB0-CRC part number.

Installing the 288-pin DDR4 DIMM module

Installation follows the standard DIMM slot procedure: align the notch with the slot key, press down firmly until the retention clips engage, and ensure the module is fully seated. The most common issue is purchasing unbuffered UDIMM or load-reduced LRDIMM modules instead of the required registered RDIMM type, which prevents the system from posting or recognising the memory.

Verifying registered ECC support before ordering

Before ordering, confirm that your motherboard and processor support DDR4 registered ECC RDIMM memory at 2400MHz and can accept 1Rx8 modules. Systems designed only for unbuffered non-ECC UDIMM or load-reduced LRDIMM will not work with this registered module. Check your system documentation for the exact qualified memory list.

Questions about this item

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

Check the memory speed and latency in your server BIOS or UEFI; it should report DDR4 2400 (PC4-19200) with CAS latency 17 at 1.20V.

What comes in the box and do I need any extra parts to install this RDIMM?

The box contains one 4GB DDR4 288-pin ECC RDIMM module; no additional components are required if your system has a free registered DIMM slot.

Which capacity or version should I choose if my server needs a 1Rx8 registered module?

This 4GB 1Rx8 DDR4 2400MHz ECC RDIMM matches the Samsung M393A5143DB0-CRC specification; select it when your system calls for a single-rank registered DIMM.
