Crucial CT16G4RFD424A 16GB DDR4 2400 ECC Registered Server RAM

SKU CH-RTCH-3JPKW MPN CT16G4RFD424A

16 GB DDR4 2400 registered ECC module with CL17 latency and 1.2 V operation for compatible servers

  • Capacity16GB
  • Type288-Pin DDR4 SDRAM
  • SpeedDDR4 2400 (PC4 19200)
  • CAS LatencyCL17
  • Voltage1.20V
  • ECCYes
  • ECC protection prevents data corruption in critical workloads
  • Registered signal buffering enables stable operation in multi-module servers
  • DDR4 2400 speed delivers 19200 MB/s bandwidth for demanding applications
  • Low 1.20V voltage reduces power draw and heat output
  • 16GB dual-rank x4 density maximises capacity per DIMM slot

Server-grade capacity

The Crucial CT16G4RFD424A provides 16GB of DDR4 memory for servers and workstations that require error correction and signal buffering. It is built for platforms that cannot use unbuffered consumer modules.

Registered DIMM integration

The 288-pin registered design places a register between the memory controller and the DRAM chips, reducing electrical load on the motherboard. This allows larger memory populations in compatible Intel Xeon and workstation boards.

Steady throughput under load

Operating at DDR4 2400 with CL17 latency and 1.20V, the dual-rank 2Rx4 modules sustain bandwidth during extended compute tasks. ECC circuitry corrects single-bit errors without halting the system.

Questions sur cet article

How many ranks does the 16 GB module present to the memory controller?

The module is dual-ranked (2Rx4), so the controller sees two ranks per DIMM.

What voltage does the DDR4 2400 registered DIMM draw under load?

It operates at the standard 1.20 V for DDR4 registered memory.

Which CPU socket and chipset combination is required to run this registered ECC DDR4?

A server platform with a 288-pin DDR4 slot and registered ECC support — for example Intel Xeon E5/E7 or Xeon Gold systems listed in the compatibility list.
