Targeted Mac Pro upgrade

This 64GB kit contains two 32GB DDR4 2666 LRDIMM modules built for the Apple iMac Pro (Late 2017). It delivers ECC load-reduced operation at 1.20V for professionals who need maximum capacity in that specific workstation.

Build integration

The 288-pin LRDIMM form factor fits the iMac Pro’s memory slots directly and requires ECC load-reduced support from the system. Using matched modules lets the memory controller run at the rated 2666/2667 MHz speed without mixing ranks or voltages.

Capacity step up

Replacing smaller DDR4 kits with this 64GB set doubles the addressable memory for large datasets, virtual machines and multi-application workloads. The jump is worth it when the current limit forces constant swapping or prevents opening the projects you work with daily.

Perguntas sobre este artigo

How much memory capacity does the 2666 MHz DDR4 LRDIMM kit provide for sustained workloads?

The kit supplies 64 GB total, delivered as two 32 GB modules running at DDR4 2666 (PC4-21300) with ECC load-reduced operation.

Does the ECC LRDIMM kit generate extra heat or noise when running continuously in an iMac Pro?

The modules operate at 1.20 V without a heat spreader; they rely on the iMac Pro's internal airflow, so they add no fan noise and minimal thermal load.

Which Apple model identifiers must the iMac Pro already have for this 288-pin DDR4 kit to be recognised?

The system must be an iMac Pro (Late 2017) with model ID iMacPro1,1, order number MQ2Y2LL/A and EMC 3144 (A1862).
