- Voltage1.20V
- ECCYes
- Buffered/RegisteredRegistered
- Rank1Rx8
- Boosts multitasking with 8GB dual-channel DDR4 2666MHz kit
- ECC registered RDIMM protects data integrity on iMac Pro
- 20V low-voltage DDR4 reduces power draw and heat
- Designed for iMac Pro 27-inch Late 2017 model A1862
- 288-pin RDIMM form factor ensures direct slot compatibility
Targeted iMac Pro upgrade
This 8 GB kit contains two 4 GB DDR4 2666 ECC registered DIMMs built for the iMac Pro (Retina 5K, 27-inch, Late 2017). The modules run at 1.20 V and use a 288-pin RDIMM form factor with 1Rx8 organisation. They match Apple order number MQ2Y2LL/A and model identifier iMacPro1,1.
Suited for ECC workloads only
The kit suits owners of the Late 2017 iMac Pro who need ECC registered memory for data-integrity tasks such as scientific computing or video editing. It will not work in standard iMacs, MacBook Pros or any system that requires unbuffered non-ECC SODIMMs. Buyers needing higher capacity should look for larger validated kits.
Straightforward slot installation
Installation means opening the iMac Pro memory compartment and seating both 288-pin modules into the available slots. The registered design demands correct alignment; forcing a module can bend pins. No heat spreader is fitted, so airflow in the compact chassis remains unchanged.

คำถามเกี่ยวกับสินค้านี้
Do I need a Late 2017 iMac Pro to use this 2666 MHz ECC RDIMM kit?
Yes, this 8 GB DDR4 kit is built for the iMac Pro 2017 (model A1862, EMC 3144) and its 288-pin RDIMM slots.
Can I mix these 1.20 V registered modules with any original Apple memory already installed?
The iMac Pro 2017 uses only ECC registered DDR4 at 2666/2667 MHz, so matching modules will run together at the same speed and voltage.
How can I confirm the kit is running at 2666 MHz with ECC active after installation?
Open System Report in macOS; it will show each 4 GB module at 2666 MHz, DDR4, ECC registered, and 1Rx8 rank.
