SK hynix HMA42GR7AFR4N-UH 16GB 2Rx4 PC4-2400T ECC server RAM

SKU CH-6D3K-M7193

16 GB registered ECC module running at 2400 MT/s with CL17 latency and 1.2 V operation

  • 16 GB ECC capacity protects data integrity
  • Registered 2Rx4 design stabilises heavy workloads
  • PC4-19200T-R speed delivers responsive throughput
  • CL17 latency reduces access delays
  • 2 V operation lowers power draw

16 GB Registered ECC Module

This 16 GB registered DIMM with error-correcting code targets servers and workstations that require data-integrity protection. It operates at PC4-19200T-R speed with a CAS latency of 17 and runs at 1.2 V. The module uses a 2Rx4 rank configuration in a standard-height form factor.

Suited for ECC Platforms Only

This module suits administrators upgrading or repairing systems that explicitly support registered ECC memory. Builders using consumer desktop boards or laptops without registered ECC support should look elsewhere, as the module will not function in those platforms.

Registered ECC with 2Rx4 Organisation

The deciding specification is the registered ECC design combined with a 2Rx4 rank layout; the motherboard and CPU memory controller must both support registered error-correcting modules with this rank organisation for the DIMM to be recognised and stable.

商品問答

How do I install the 2Rx4 registered ECC module and which step is often missed?

Align the notch with the slot key, press down firmly until both retention clips click, and ensure the system BIOS recognises the registered ECC configuration at 1.2V.

What maintenance or replacement will the 16 GB PC4-19200T-R module need later?

No scheduled maintenance is required; replace the module only if memory diagnostics report uncorrectable ECC errors or the system fails to boot.

What limit appears first on the CL17 2400 MT/s kit under sustained load?

The rated 2400 MT/s speed with CL17 latency is the primary limit; sustained workloads will not exceed this JEDEC specification.
