A-Tech 4GB DDR4 2400MHz ECC RDIMM 1Rx8 for Samsung M393A5143DB0-CRC Server Memory

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.
