Black 288-pin DDR4 UDIMM module with green PCB and gold contacts

OWC

OWC 16GB DDR4 2933MHz CL21 ECC Unbuffered UDIMM 1.2V 288-pin desktop RAM

SKU CH-VKK0-1D7H1

16GB DDR4 2933MHz ECC unbuffered UDIMM for workstations, servers and NAS, CL21 at 1.2V with backward compatibility to 2666, 2400 and 2133MHz

  • Capacity16GB
  • SpeedDDR4 2933 (PC4 23400)
  • CAS LatencyCL21
  • Voltage1.2V
  • ECCYes
  • Buffered/RegisteredUnbuffered

Capacity 16GB

  • Error-correcting code protects data integrity in workstations and servers
  • 16GB capacity expands multitasking headroom for demanding workloads
  • 2933MHz DDR4 speed delivers responsive throughput for memory-intensive tasks
  • 2V operation reduces power draw and heat in dense configurations
  • Backward compatible with 2133, 2400 and 2666MHz systems for flexible deployment

Workstation ECC UDIMM

This 16GB DDR4 module delivers 2933MHz speed with CL21 latency and ECC error correction. It operates at 1.2V and uses a 288-pin unbuffered design suited for desktop PCs, workstations, servers and NAS systems. The single-rank 1Rx8 layout provides straightforward capacity scaling without registered buffering overhead.

Upgrade from non-ECC or slower DDR4

Replaces standard non-ECC memory where data integrity matters, adding single-bit error correction for critical workloads. The jump is worth it when moving from 2133MHz, 2400MHz or 2666MHz modules to the 2933MHz PC4-23400 rating for higher throughput. Backward compatibility ensures it runs at lower speeds if the platform requires it.

16GB capacity for multi-tasking headroom

Comfortably handles multiple applications, larger files and concurrent workloads in supported desktop, workstation, server or NAS environments. Runs out when total installed memory exceeds the platform's maximum addressable limit or when registered DIMM slots are required instead of unbuffered. JEDEC compliance guarantees standard voltage and timing operation across compatible systems.

Perguntas sobre este artigo

Will this module work in a motherboard that only supports 2666 MHz memory?

Yes, the module is backward compatible with 2133 MHz, 2400 MHz and 2666 MHz systems and will run at the board's maximum supported speed.

Does this ECC memory require a workstation or server motherboard to function?

ECC functionality requires a compatible motherboard and CPU; on standard desktop boards the module will operate as non-ECC memory.

Is a heat spreader included or needed for this 1.2 V module?

No heat spreader is included; the module runs at the standard 1.2 V and is designed to operate within JEDEC thermal limits without one.
