16 GB DDR5 ECC Registered DIMM

This 16 GB DDR5 module runs at 6400 MT/s with ECC and registered signalling for data-integrity workloads. It uses a 288-pin form factor and operates at 1.1 V. The single-rank layout suits servers and workstations that require registered memory. It is not for desktop boards that accept only unbuffered non-ECC DIMMs.

Thermals noise and power draw

Standard DDR5 voltage of 1.1 V keeps power draw low during typical server operation. The registered buffer adds minimal latency while improving signal stability under sustained load. No active cooling is required on the module itself; airflow from the chassis is sufficient. Acoustic output is silent because the DIMM has no moving parts.

Highlights

  • ECC protection guards data integrity in critical workloads
  • DDR5-6400 speed moves large datasets quickly
  • Single-rank 16 GB module fits dense server configurations
  • 1 V operation reduces power draw per DIMM

Questions about this item

How do I install this 288-pin DDR5 ECC Registered DIMM and which step is often missed?

Align the key notch with the slot, press firmly until both retention clips click, and verify the module is fully seated; the step often missed is checking that both clips lock completely.

What maintenance or replacement will this 16GB 1.1V single-rank module need later?

No scheduled maintenance is required; replacement is only necessary if a memory error occurs or a capacity upgrade is desired.
