Black 288-pin DDR4 UDIMM module, no heat spreader

OWC

OWC 32GB DDR4 3200MHz CL22 ECC Unbuffered UDIMM desktop RAM

SKU CH-D8NS-AXE0A

32GB DDR4 3200MHz ECC unbuffered UDIMM for workstations, servers and NAS systems

  • Capacity32GB
  • SpeedDDR4 3200 (PC4 25600)
  • CAS LatencyCL22
  • Voltage1.2V
  • ECCYes
  • Buffered/RegisteredUnbuffered

Capacity 32GB

  • ECC protection guards data integrity in critical workloads
  • 32GB single module expands capacity without occupying extra slots
  • 3200MHz DDR4 speed delivers responsive multitasking performance
  • 2V operation reduces power draw and heat output
  • Backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz systems

Single 32GB DDR4 ECC module

This OWC UDIMM provides 32GB of DDR4 memory rated at 3200MHz with a CAS latency of 22. It operates at 1.2V and uses a 288-pin unbuffered layout with on-die error correction for data integrity.

Workstations servers and NAS builds

The module targets workstations, servers and NAS systems that require ECC protection. Desktop PCs without ECC support in the memory controller will not benefit from the error-correction feature and should consider non-ECC alternatives.

32GB capacity for heavy multitasking

A single 32GB stick handles large datasets, virtual machines and simultaneous applications with ample headroom. Workloads that exceed 32GB of active memory will require additional modules or a higher-capacity configuration.

Questions about this item

Does my motherboard need a 288-pin DDR4 slot that supports ECC unbuffered memory?

Yes, this module is a 288-pin DDR4 ECC unbuffered UDIMM and requires a motherboard with a matching slot and chipset that enables ECC functionality.

Will this 3200MHz CL22 stick downclock to 2666MHz if my older CPU only supports that speed?

The specifications list backward compatibility with 2133MHz, 2400MHz, 2666MHz and 2933MHz, so it will run at the highest speed the memory controller allows.

How can I confirm the module is running at 3200MHz with ECC active after installation?

Check the memory speed and ECC status in your BIOS or UEFI, or use an operating-system tool such as dmidecode on Linux or CPU-Z on Windows to verify the operating frequency and error-correction state.
