SK hynix 16GB DDR4-2400R Registered ECC 2Rx4 CL17 1.20V 288-pin RDIMM

SKU CH-YDC3-QJJTK

16 GB DDR4-2400 registered ECC RDIMM with CL17 latency, 2Rx4 organisation and 1.20 V operation

  • 16 GB capacity for demanding workloads
  • Registered ECC design protects data integrity
  • CL17 latency at DDR4-2400 speed
  • 2Rx4 organisation maximises density
  • 20 V operation reduces power draw

16 GB DDR4-2400R ECC RDIMM

This 16 GB DDR4 registered ECC module targets servers and workstations that require error-correcting memory. The registered signal and ECC function protect data integrity in multi-module configurations. It suits system builders who need validated, stable capacity for 24/7 operation.

Registered ECC with 2Rx4 organisation

The single specification that decides fit is the registered ECC 2Rx4 layout combined with DDR4-2400R speed. Only platforms that explicitly support registered DIMMs and this rank structure will POST correctly. Consumer desktop boards without registered support cannot use this module.

Steady throughput at CL17 1.20 V

Under sustained load the module maintains DDR4-2400R transfer rates at CL17 latency while drawing 1.20 V. The registered buffer reduces electrical load on the memory controller, allowing consistent bandwidth during long compute jobs without the timing drift seen in unbuffered alternatives.

  • Registered ECC design protects data integrity
  • CL17 latency at DDR4-2400 speed
  • 2Rx4 organisation maximises density

Questions about this item

What does DDR4-2400R mean for real-world throughput in a system?

DDR4-2400R indicates a data rate of 2400 MT/s; actual bandwidth depends on the memory controller and channel configuration of the platform.

What does PC4-19200 tell me about the module's rated ceiling?

PC4-19200 is the JEDEC designation that corresponds to the DDR4-2400 speed grade for this registered ECC module.

Will the 288-pin RDIMM fit a standard desktop DIMM slot?

The 288-pin RDIMM form factor matches the DDR4 DIMM slot, but the platform must support registered ECC memory for it to function.
