OWC

OWC 64GB DDR4 3200 ECC Registered RDIMM CL22 2Rx4 288-pin 1.2V server RAM

SKU CH-XDZS-CMSHR

A single 64 GB DDR4 3200 ECC registered RDIMM with CL22 latency for servers, workstations and NAS systems

  • Type288-Pin DDR4 ECC RDIMM
  • CAS Latency22
  • Voltage1.2V
  • ECCYes
  • Buffered/RegisteredRegistered
  • Heat SpreaderNo
  • 64GB single module expands server capacity
  • ECC registered design corrects data errors in real time
  • DDR4 3200MHz CL22 delivers high-speed registered performance
  • 2V JEDEC standard voltage ensures efficient operation
  • Backward compatible with 2133, 2400, 2666 and 2933MHz systems

Single-Module Capacity

This OWC module delivers 64 GB of DDR4 ECC Registered memory in a single 288-pin RDIMM. It runs at 3200 MHz with CAS latency 22 and operates at 1.2 V. The part is designed for server, workstation and NAS platforms that require registered error-correcting memory.

Compatibility Constraints

The module suits administrators upgrading or populating systems that accept DDR4 ECC Registered RDIMMs and can utilise a 64 GB density per slot. It will not work in standard desktop computers, nor can it be mixed with unbuffered or load-reduced ECC memory types.

Headroom And Limits

Backward compatibility covers 2133, 2400, 2666 and 2933 MHz operation, so the module can slot into slower DDR4 channels without configuration changes. Capacity headroom ends at 64 GB per DIMM; systems needing more memory per channel must add additional modules where the platform allows.

Points forts

  • 64GB single module expands server capacity
  • ECC registered design corrects data errors in real time
  • DDR4 3200MHz CL22 delivers high-speed registered performance
  • 2V JEDEC standard voltage ensures efficient operation
  • Backward compatible with 2133, 2400, 2666 and 2933MHz systems

Questions sur cet article

Does this 64 GB DDR4 RDIMM need a motherboard that supports ECC registered memory?

Yes, this module is ECC registered and requires a server or workstation motherboard that supports registered DIMMs; it will not work in standard desktop boards.

Can I run this 3200 MHz stick alongside my existing 2666 MHz DDR4 modules?

The module is backward compatible with 2133, 2400, 2666 and 2933 MHz speeds, so it will operate at the speed of the slowest installed module.

How do I confirm the system sees the full 64 GB at 3200 MHz with ECC active?

Check the BIOS memory information or run a tool such as dmidecode to verify capacity, speed and ECC status after installation.
