16GB DDR4 ECC UDIMM for Servers

This 16GB DDR4 2666MHz module targets administrators upgrading or repairing server and workstation platforms that require ECC unbuffered memory. It replaces several Micron part numbers including MTA18ADF2G72AZ-2G6E1 and MTA18ASF2G72AZ-2G6D1. The single stick delivers 16GB capacity at CL19 latency.

ECC and Testing Impact

Built-in ECC detects and corrects single-bit errors to protect data integrity in continuous workloads. Each module undergoes quality-assurance testing before shipment to verify reliable operation. The unbuffered design suits platforms that do not support registered DIMMs.

Verify Platform Compatibility

Confirm your system accepts DDR4 2666 ECC unbuffered UDIMMs in a 288-pin form factor with 2Rx8 organisation and 1.20V operation. Check the motherboard or chassis documentation for maximum supported capacity per slot and total memory limit. Buyers needing registered DIMMs or non-ECC memory should select a different module.

Perguntas sobre este artigo

Will the 2Rx8 ECC chips on this 16GB DDR4 module need replacement after a certain period?

The 2Rx8 ECC UDIMM uses Micron chipset components tested for server workloads; no scheduled chip replacement is required under normal operation.

What limit appears first when this 2666MHz CL19 stick runs sustained loads?

The CL19 latency at 2666MHz sets the throughput ceiling before thermal or voltage limits are reached on this 1.20V module.

How much heat and power does this 1.20V DDR4 DIMM produce during all-day operation?

At the standard 1.20V DDR4 voltage the 288-pin UDIMM draws minimal power and generates low heat, keeping noise unchanged in a server chassis.
