Server DDR4 ECC RDIMM

This 16GB DDR4 2400MHz ECC registered DIMM targets servers and workstations that require error-correcting memory. The module operates at CL17 latency with a standard 1.20V voltage and uses a 2Rx4 Samsung chipset configuration.

Verify registered DIMM support

Confirm your motherboard accepts registered ECC DDR4 DIMMs before ordering, as consumer boards often reject registered modules. Check that the system supports DDR4 2400MHz speed and can address 16GB per slot. Match the 288-pin form factor to your available memory slots.

Direct Samsung replacement

This module replaces Samsung M393A2G40DB1-CRC4Q and M393A2G40EB1-CRC0Q part numbers without requiring configuration changes. The identical specifications maintain system stability and ECC functionality across the memory subsystem.
