16 GB DDR4 2666 MHz ECC UDIMM module with CL19 latency and 1.20 V operation

  • Capacity16GB
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.20V
  • ECCYes
  • Buffered/RegisteredUnbuffered
  • 16 GB DDR4 2666 MHz ECC UDIMM for server workloads
  • CL19 latency and 1.20 V voltage for stable operation
  • 2Rx8 dual-rank layout increases memory density
  • 288-pin DDR4 DIMM form factor fits standard server slots
  • Major-brand chipset and chips tested for reliable performance

Capacity and Compatibility

This is a single 16GB DDR4 2666MHz ECC UDIMM module built for server and workstation systems. It uses a 288-pin DIMM form factor and runs at the standard 1.2V voltage with CL19 latency. The module is a direct replacement for Micron part numbers MTA18ADF2G72AZ-2G6 and MTA18ASF2G72AZ-2G6.

Suitable Systems and Limitations

This memory suits administrators upgrading compatible servers or workstations that require ECC unbuffered DDR4 modules. It is not suitable for platforms that only accept registered or load-reduced DIMMs, nor for desktop boards that lack ECC support in the BIOS. Buyers needing higher densities or faster speeds should verify their hardware specifications first.

Installation Notes

Installation follows the standard DIMM slot procedure: align the notch, press firmly until the retention clips engage, and ensure the module is fully seated. The most common issue is purchasing ECC UDIMM for a system that requires registered memory, which will prevent boot. Confirm the exact memory type supported by your motherboard before ordering.

Questions sur cet article

What motherboard slot does this 288-pin DDR4 DIMM need to fit and work?

It requires a standard DDR4 UDIMM slot that supports 2666 MHz ECC unbuffered memory at 1.2 V.

Can I mix this 2Rx8 ECC UDIMM with older single-rank DDR4 modules in the same server?

Mixing ranks is possible if the platform allows it, but the system will run all modules at the lowest common speed and voltage.

How can I confirm the module is running at 2666 MHz with ECC active after installation?

Check the BIOS memory information or use a tool like CPU-Z to verify 2666 MT/s, CL19 timings, and ECC status showing enabled.
