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

SKU CH-ZKEM-14Y6W

A single 64 GB DDR4 3200 ECC registered RDIMM with CL22 latency and 1.2 V operation for server and workstation upgrades

  • Type288-Pin DDR4 ECC RDIMM
  • CAS Latency22
  • Voltage1.2V
  • ECCYes
  • Buffered/RegisteredRegistered
  • Heat SpreaderNo
  • ECC registered design protects data integrity in servers and workstations
  • 64GB single module maximises capacity per slot for dense configurations
  • 3200MHz CL22 at 1.2V delivers JEDEC-standard performance and efficiency
  • Backward compatible with 2133, 2400, 2666 and 2933MHz systems for flexible deployment
  • 288-pin RDIMM form factor fits registered DIMM slots in servers, workstations and NAS

Single-module capacity and purpose

This is a single 64GB DDR4 3200 ECC Registered RDIMM designed for servers, workstations and NAS systems. It operates at 1.2V with a CAS latency of 22 and uses a 288-pin form factor. The module is not compatible with standard desktop computers.

Registered ECC and JEDEC compliance

The registered buffer and ECC functionality provide error correction and signal stability required by multi-socket platforms. JEDEC and RoHS compliance ensures a warranty-safe upgrade that meets OEM specifications. Backward compatibility covers 2133, 2400, 2666 and 2933MHz speeds.

Suited for registered-memory platforms only

This module suits administrators upgrading or repairing systems that require registered ECC DDR4 memory in 64GB densities. Builders needing unbuffered or load-reduced DIMMs, or anyone assembling a standard desktop PC, should look at a different memory type.

Points forts

  • ECC registered design protects data integrity in servers and workstations
  • 64GB single module maximises capacity per slot for dense configurations
  • 3200MHz CL22 at 1.2V delivers JEDEC-standard performance and efficiency
  • Backward compatible with 2133, 2400, 2666 and 2933MHz systems for flexible deployment

Questions sur cet article

Will the 64GB DDR4 3200 ECC RDIMM need a heat spreader added later for sustained loads?

The module ships without a heat spreader and operates at 1.2V; most server chassis provide sufficient airflow, so no retrofit is required under normal conditions.

What limits continuous throughput first — the CL22 latency or the 3200 MT/s bus?

The 3200 MT/s JEDEC bus sets the peak bandwidth ceiling; CL22 latency determines access delay but does not cap sustained transfer rates.

How much power and heat does the 1.2V 2Rx4 module produce when running 24/7?

At 1.2V the 64GB RDIMM draws modest power typical for DDR4 registered ECC, and the lack of a heat spreader indicates low thermal output in ventilated server bays.
