8GB DDR4 2666MHz ECC RDIMM Server Memory

This 8GB registered DIMM uses DDR4 2666MHz PC4-21300 memory with ECC error correction and a 2Rx8 rank configuration. It operates at the standard DDR4 voltage of 1.20V and features CL19 latency. The module is built as a compatible replacement for the Micron MTA18ASF1G72PDZ-2G6E1 part number using Micron chipset components. It targets servers and workstations that require registered ECC memory for data integrity.

Verify DDR4 RDIMM slot and registered memory support

Before ordering, confirm that your system accepts DDR4 registered DIMMs with ECC functionality and a 288-pin form factor. The motherboard or server platform must specifically support registered (buffered) memory topology; unbuffered UDIMMs are not interchangeable. Check the qualified vendor list or manual for 2666MHz speed compatibility and 2Rx8 rank population rules. Ensure the platform does not require load-reduced LRDIMMs or a different voltage specification.

Standard 1.20V DDR4 voltage limits heat

At the standard DDR4 voltage of 1.20V, this module runs within typical server thermal envelopes without requiring active cooling beyond normal chassis airflow. Registered buffering adds minimal latency overhead while stabilising the memory bus for sustained workloads. Power consumption remains consistent with other 8GB DDR4 RDIMMs at this frequency. Acoustic output is silent as the component has no moving parts.

Preguntas sobre este artículo

What comes in the box and do I need anything else to install this 8GB DDR4 2666MHz ECC RDIMM?

The package contains one 8GB DDR4 2666MHz ECC RDIMM module; no additional components are required for installation beyond a compatible 288-pin DIMM slot.

Should I choose the 2Rx8 registered version or look for a different rank configuration for my server?

Select this 2Rx8 registered ECC module when your server requires registered DIMMs with dual-rank x8 organisation; verify your system documentation for supported rank and buffer types.

What does the PC4-21300 rating mean for actual throughput in my machine?

PC4-21300 is the module's rated data-rate designation for DDR4 2666MHz operation; real-world throughput depends on your platform's memory controller and channel configuration.
