64GB DDR4 2933MHz ECC RDIMM

This OWC module delivers 64GB of DDR4 2933MHz ECC Registered memory in a 288-pin RDIMM form factor. It operates at 1.2V with CL21 latency and a 2Rx4 rank configuration. The part number is 2R9D42R464GB and it matches the specifications of the Kingston KTD-PE429/64G reference.

Compatibility: Servers and Workstations Only

This memory is designed for servers, workstations and NAS systems that require ECC Registered DDR4 RDIMMs. It will not work in standard desktop computers or laptops that use unbuffered non-ECC memory. Buyers needing unbuffered DIMMs or SODIMM form factors should look elsewhere.

Key Spec: 64GB 2Rx4 Registered ECC

The single specification that determines fit is the 64GB 2Rx4 Registered ECC RDIMM configuration at DDR4 2933MHz. Your system must support Registered ECC memory and accept 2Rx4 modules at this density. The module is backward compatible with 2133MHz, 2400MHz and 2666MHz bus speeds.

Points forts

  • ECC protection prevents data corruption in critical workloads
  • 64GB capacity expands server memory for heavy multitasking
  • DDR4 2933MHz speed matches PC4-23400 bandwidth demands
  • Registered 2Rx4 design stabilises multi-module server configurations
  • JEDEC and RoHS compliance ensures warranty-safe upgrades

Questions sur cet article

Does this 288-pin DDR4 RDIMM fit a standard server DIMM slot?

Yes, the 288-pin DDR4 registered form factor matches standard server and workstation DIMM slots.

What is the correct way to seat the module so the ECC registered buffer initialises?

Align the notch with the slot key, press firmly until both retention clips click, then power on to let the BIOS train the registered buffer at 2933 MHz.

When should I consider replacing this 64 GB module in a 24/7 server?

Replace if ECC correctable-error counts rise steadily or if the system logs uncorrectable errors during sustained 1.2 V operation.
