16GB DDR4 ECC UDIMM for Servers

This 16GB DDR4 2400 ECC unbuffered DIMM targets servers and workstations that require error-correcting memory. It operates at 1.2V with CL17 latency and a 2Rx8 organisation. The module replaces several Micron part numbers including MTA18ASF2G72AZ-2G3A1 and MTA18ADF2G72AZ-2G3H1.

Installation is tool-free and takes seconds

Align the 288-pin edge connector with the motherboard slot and press down until the retention clips lock. Ensure the system supports DDR4 ECC unbuffered memory; inserting the module into a board that expects registered DIMMs or non-ECC memory will prevent boot. Handle only the edges to avoid static damage.

Verify your platform before ordering

Confirm the motherboard accepts 16GB unbuffered ECC UDIMMs at 2400MT/s and 1.2V. Check the qualified vendor list for the specific Micron part numbers listed above. Systems limited to registered memory, lower capacities, or different voltages will not recognise this module.
