Mac Pro 2019 memory kit

This 16GB kit contains two 8GB DDR4 2666 ECC RDIMM modules built for the 2019 Mac Pro 8-Core in both tower and rack configurations. It targets professionals who need to expand system memory for heavier workloads on Apple’s Xeon workstation platform.

ECC RDIMM 288-pin requirement

The modules use registered ECC DDR4 at 2666 MHz with a 288-pin RDIMM form factor, which is the only memory type the Mac Pro 7,1 architecture accepts. Standard unbuffered DIMMs will not function in this system.

Lifetime warranty and US support

A-Tech backs the kit with a lifetime warranty and provides complimentary United States based technical support before, during and after purchase, giving buyers direct assistance for installation or troubleshooting.

Preguntas sobre este artículo

What does the 2666 MHz speed mean for my Mac Pro 2019?

The modules run at DDR4-2666, the native memory clock for the 2019 Mac Pro, so the system operates at its rated throughput without downclocking.

How does the ECC RDIMM interface affect compatibility?

The kit uses 288-pin registered ECC DDR4, which is the exact module type the Mac Pro 2019 memory slots require; non-registered or non-ECC DIMMs will not work.

What physical clearance do the 8 GB modules need inside the Mac Pro?

Each stick is a standard-height 288-pin RDIMM and fits the Mac Pro 2019 DIMM slots without interfering with the CPU heatsink or fan assembly.
