Product Identity

This OWC 64GB DDR4 2933MHz ECC Registered RDIMM is a server-grade memory upgrade built for specific Supermicro motherboards. It delivers 64GB of capacity in a single 288-pin module operating at 1.2V with CL21 latency. The part is validated for X11DPG-SN, X11DPH-I, X11DPH-T, X11DPH-Tq and X11DPi-N platforms.

Suitable Buyers

This module suits administrators expanding Supermicro X11 dual-socket servers that require registered ECC DDR4 memory. It is not for desktop PCs, workstations using unbuffered DIMMs, or any system that cannot accept registered modules. Mixing with unbuffered memory will prevent boot. Buyers needing unbuffered ECC or non-ECC DDR4 should look elsewhere.

Deciding Specification

The registered ECC RDIMM form factor is the single specification that decides compatibility. Only motherboards designed for registered DDR4 DIMMs can use this module; standard desktop boards and unbuffered-only workstations will not accept it.

Points forts

  • ECC registered design protects data integrity in servers
  • 64GB capacity expands memory for demanding workloads
  • 2933MHz DDR4 speed with CL21 latency
  • 2V operation reduces power consumption
  • Compatible with Supermicro X11DPG-SN, X11DPH-I, X11DPH-T, X11DPH-Tq, X11DPi-N

Questions sur cet article

Which motherboards must I already have for this 288-pin DDR4 2933MHz ECC registered RDIMM to work?

This module is validated for Supermicro X11DPG-SN, X11DPH-I, X11DPH-T, X11DPH-Tq and X11DPi-N motherboards.

Can I keep my existing 2133MHz, 2400MHz or 2666MHz DDR4 ECC registered DIMMs and add this 2933MHz CL21 kit alongside them?

The module is backward compatible with 2133MHz, 2400MHz and 2666MHz speeds, but all installed DIMMs must be ECC registered; mixing with unbuffered memory is not supported.

How do I confirm the 64GB 2Rx4 module is running at 2933MHz with ECC active after installation?

Check the BIOS memory information or use a tool such as dmidecode to verify speed shows 2933MHz, type shows DDR4 ECC registered, and total capacity reflects the added 64GB.
