4GB DDR4 2400 ECC UDIMM for servers

This A-Tech module adds 4GB of DDR4 2400 memory with ECC error correction. It is built for servers and workstations that require data integrity. The unbuffered DIMM uses major brand chips and runs at standard 1.20V voltage.

Check motherboard slots and maximum capacity

Verify that your system accepts DDR4 288-pin UDIMMs and supports ECC unbuffered memory. Confirm the maximum memory per slot and total capacity allowed by the motherboard. The module operates at CL17 latency and 1.20V.

Replaces Samsung M391A5143EB1-CRC

This kit serves as a direct equivalent for the Samsung part number. Upgrading is worthwhile when your current modules are slower, lack ECC, or when you need to fill empty slots for higher total memory.
