A-Tech 768GB Kit (12x64GB) DDR4 2933 ECC LRDIMM Memory Upgrade

SKU CH-KZF6-GE7GW

A 768GB DDR4 2933 ECC LRDIMM kit of twelve 64GB modules for Apple Mac Pro 2019 models with 12, 16, 24 or 28-core Xeon processors

  • Buffered/RegisteredLoad Reduced
  • ChipsetMajor Brand Chipset
  • Massive 768GB capacity from twelve 64GB modules
  • DDR4 2933MHz speed for fast data throughput
  • ECC Load Reduced technology protects data integrity
  • Certified for Apple Mac Pro 2019 models
  • 20V low voltage reduces power consumption

Target System Compatibility

This 768GB kit contains twelve 64GB DDR4 2933 ECC LRDIMM modules built for the 2019 Apple Mac Pro tower and rack models. It supports the 12-core, 16-core, 24-core and 28-core Xeon configurations identified by model IDs MacPro7,1 and order numbers A2304 and A1991.

DDR4 2933 Interface Limits

The memory runs at 2933 MT/s (PC4-23400) with a 1.20V supply and uses a load-reduced registered design to lighten the electrical load on the memory controller. ECC protection corrects single-bit errors, while the 4Rx4 organisation allows the high density required for the maximum 12-slot population.

288-Pin LRDIMM Build Quality

Each module uses major-brand DRAM chips on a 288-pin LRDIMM PCB and is tested to meet Apple Mac certification requirements. The load-reduced buffer improves signal integrity when all twelve slots are filled, so the kit remains stable under sustained heavy workloads. Users needing fewer than twelve modules or a different capacity should select a smaller kit.

Questions sur cet article

Should I choose the 768GB kit with twelve 64GB modules or a smaller capacity for my Mac Pro?

The 768GB kit fills all twelve memory slots with 64GB LRDIMMs, giving the maximum supported capacity for 2019 Mac Pro models with 12, 16, 24 or 28‑core Xeon W processors.

What does the DDR4 2933 speed mean for real‑world performance in a Mac Pro?

At 2933 MHz the modules run at the native memory‑controller frequency of the Xeon W‑3275M, W‑3265M, W‑3245 and W‑3235 CPUs, delivering full bandwidth without down‑clocking.

How does the ECC Load‑Reduced 288‑pin interface affect compatibility and limits?

The ECC LRDIMM 288‑pin design is required by the Mac Pro (2019) memory architecture; it supports the 768GB kit across all listed MacPro7,1 configurations and caps at the platform’s twelve‑slot maximum.
