Model Micron

  • 32 GB capacity gives room for complex apps
  • 2666 MHz speed with registered signal runs heavy workloads smoothly
  • ECC and registered design protect data integrity
  • CL19 latency delivers fast, reliable response
  • 288-pin DDR4 form factor fits server DIMM slots

Capacity and role

This 32 GB DDR4 module is built for servers and workstations that require registered ECC memory. The dual-rank 2Rx8 organisation and CL19 timing suit heavy multi-threaded workloads and virtualisation hosts.

Platform checks

Verify that your motherboard supports registered DDR4 DIMMs and accepts 2666 MT/s modules at 1.20 V. The 288-pin form factor fits standard DDR4 slots, but unbuffered consumer boards will not recognise registered memory.

Registered ECC benefit

On-die ECC corrects single-bit errors while the registered buffer reduces electrical load on the memory controller. Together they improve data integrity and allow larger memory populations without signal degradation.

Questions about this item

What does the single 32 GB module include and is any extra hardware required?

The box contains one 288-pin DDR4 registered DIMM rated at 2666 MT/s with CL19 timing and 1.20 V operation; no additional components are needed for installation.

When would the 32 GB 2Rx8 registered ECC version be the right choice over other capacities?

Choose this 32 GB dual-rank module when your server or workstation board requires registered ECC memory and you need maximum capacity per slot at the 2666 MT/s speed grade.

What does the 2666 MT/s rating mean for actual throughput in a compatible system?

At 2666 MT/s the module delivers a peak transfer rate of PC4-21300, giving roughly 10K MIPS headroom for heavy multi-threaded workloads.
