OWC 16GB DDR4 2933MHz ECC Registered DIMM Memory for Mac Pro (2019)

Standard desktop DIMMs fall short in high-density workstations and servers, but this OWC module is built for the Mac Pro (2019) and compatible systems that demand registered architecture and error-correcting code. With 16GB of DDR4 ECC RDIMM capacity at 2933MHz, it delivers the stability required for heavy rendering, virtualization, and multi-user workloads. The dual-rank design and CL21 latency balance bandwidth with signal integrity, while the 288-pin form factor ensures a direct fit in systems that require RDIMMs rather than unbuffered modules.

Highlights

• 16GB DDR4 RDIMM with ECC for mission-critical reliability
• 2933MHz (PC4-23400) speed to keep up with multi-core CPUs
• Registered, dual-rank module for high-density memory configurations
• 288-pin DIMM, 1.2V JEDEC standard for broad compatibility
• Specifically validated for Mac Pro (2019) and compatible servers/workstations

In daily use

When you populate all slots of a Mac Pro or a dual-socket server, signal integrity becomes the limiting factor. This module's registered buffer reduces electrical load on the memory controller, allowing stable operation even with six or twelve DIMMs installed. ECC detects and corrects single-bit errors on the fly, preventing silent data corruption that could ruin a render job or database transaction. The 2933MHz clock speed provides ample bandwidth for memory-hungry applications, while the 1.2V operating voltage helps keep thermals in check inside tightly packed chassis.
