  • Voltage1.20V
  • ECCYes
  • Buffered/RegisteredRegistered
  • 64GB capacity handles heavy server workloads
  • ECC registered design protects data integrity
  • DDR4 2933MHz speed delivers high bandwidth
  • CL21 latency at 1.2V optimises efficiency
  • 288-pin 2Rx4 module fits standard DDR4 slots

What this module is and who needs it

This 64GB DDR4 2933 ECC RDIMM is a registered server memory module built for systems that require error-correcting code and registered signal integrity. It suits administrators upgrading or repairing compatible Hynix-equipped servers and workstations where this exact specification is validated.

Who this suits and who should look elsewhere

It fits workloads demanding 64GB per DIMM slot with CL21 timing at 1.2V on a 288-pin interface. It is not for desktop or consumer motherboards that lack RDIMM support, nor for platforms limited to unbuffered UDIMM memory.

The spec that decides compatibility

The module uses a 2Rx4 rank organisation with DDR4 2933 (PC4-23400) speed and registered ECC functionality; your system must explicitly support this rank structure, voltage, and registered DIMM type for the module to operate.

Points forts

  • 64GB capacity handles heavy server workloads
  • ECC registered design protects data integrity
  • DDR4 2933MHz speed delivers high bandwidth
  • CL21 latency at 1.2V optimises efficiency
  • 288-pin 2Rx4 module fits standard DDR4 slots

Questions sur cet article

Does my motherboard need 288-pin DDR4 RDIMM slots to use this 64GB module?

Yes, this is a 288-pin DDR4 RDIMM that requires registered DIMM slots on a server or workstation board.

Will this CL21 2933MHz module run at full speed if I keep slower DDR4 RDIMMs installed?

The system will clock all modules to the speed of the slowest installed kit, so this module will downclock to match slower DDR4 RDIMMs.

How can I verify the module is operating as ECC registered memory after installation?

Check the BIOS or OS memory report for 64GB capacity, 2933MHz speed, CL21 timings, 1.2V voltage, and ECC registered status.
