16 GB DDR4 2933 MHz ECC registered DIMM for 2019 Mac Pro tower and rack models

  • 16 GB capacity expands Mac Pro 2019 memory headroom
  • 2933 MHz DDR4 speed matches factory specification
  • ECC registered design protects data integrity
  • 288-pin RDIMM form factor fits Mac Pro 7,1 slots
  • CL21 latency at 1.2 V for efficient operation

16 GB DDR4 ECC RDIMM for Mac Pro 2019

This 16 GB DDR4 2933 MHz ECC registered DIMM is built for the Mac Pro 2019 (MacPro7,1). It fits every 2019 tower and rack configuration from the 8-core up to the 28-core Xeon W models.

Registered ECC design prevents mixed-configuration

The module uses registered ECC circuitry at 1.2 V with a CL21 latency. The Mac Pro 2019 requires either RDIMM or LRDIMM exclusively; mixing the two types will stop the system from functioning.

PC4-23400 2933 MHz speed rating

This single spec decides compatibility. The stick runs at PC4-23400 2933 MHz and is backward compatible with PC4-21300 2666 MHz slots, so it installs in any 2019 Mac Pro memory bay without speed mismatch.

商品問答

Will the 288-pin RDIMM need any firmware updates or cleaning over time?

No firmware updates or cleaning are required for the 288-pin RDIMM; the module is a solid-state component with no moving parts.

What limit appears first when the PC4-23400 2933MHz ECC RDIMM runs under sustained load?

The CAS latency of CL21 at 1.2 V sets the timing boundary; the registered buffer and ECC logic keep errors corrected within that window.

How much heat and fan noise does the 16 GB DDR4 2933 MHz module add when the Mac Pro 2019 runs all day?

At 1.2 V the module draws minimal power, so it adds negligible heat and no audible fan noise in the Mac Pro 7,1 cooling system.
