OWC

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

SKU CH-G4FB-68DMQ

A single 64 GB DDR4 3200 CL22 registered ECC RDIMM for servers, workstations and NAS systems, backward compatible with 2133, 2400, 2666 and 2933 MHz speeds

  • Type288-Pin DDR4 ECC RDIMM
  • CAS Latency22
  • Voltage1.2V
  • ECCYes
  • Buffered/RegisteredRegistered
  • Heat SpreaderNo
  • 64GB single module expands server memory capacity
  • ECC registered design protects data integrity in critical workloads
  • DDR4 3200MHz CL22 speed matches modern platform requirements
  • 2V operation reduces power draw per module
  • Backward compatible with 2133, 2400, 2666 and 2933MHz systems

Target server and workstation upgrades

This OWC 64GB DDR4 3200 CL22 ECC Registered RDIMM is built for servers, workstations and NAS systems that require registered memory with error correction. It operates at 1.2V using a 288-pin interface and delivers 64GB in a single 2Rx4 module. Standard desktop computers cannot use this memory type.

Registered ECC limits and speed floor

Registered ECC modules must not be mixed with unbuffered or load-reduced memory in the same system. The module runs at PC4-25600 3200MHz with CL22 timing and is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz bus speeds. JEDEC compliance ensures correct operation at each supported rate.

Replaces Dell AB214253 and smaller registered DIMMs

This part replaces Dell AB214253 and upgrades systems running lower-capacity registered ECC DIMMs. The jump is worthwhile when the platform supports 64GB per slot and the workload needs maximum memory density without adding modules. Builders needing unbuffered memory or load-reduced DIMMs must choose a different product.

Questions sur cet article

Is this a single 64GB stick or a kit of smaller modules?

It is a single 64GB DDR4 3200 CL22 2Rx4 288-pin 1.2V ECC Registered RDIMM module.

What does the 3200MHz rating actually deliver in a server?

The module runs at 3200MHz CL22 with a 1.2V supply and will down-clock to 2933MHz, 2666MHz, 2400MHz or 2133MHz if the platform requires it.

Does the DDR4 PC4-25600 interface limit the bandwidth I can use?

The DDR4 PC4-25600 interface provides up to 25600 MB/s theoretical bandwidth; actual throughput is capped by the memory controller and channel population of the server or workstation.
