32GB DDR3L Kit for 27-inch iMac Late 2015

This 32GB kit contains two 16GB DDR3L 1866 SODIMM modules built for the Apple iMac (Retina 5K, 27-inch, Late 2015). It matches the factory memory type and pin count for that specific model. Buyers upgrading compatible iMacs can install both modules to reach the full 32GB capacity.

Verify model ID iMac17,1

Check that your iMac carries model identifier iMac17,1 and one of the listed order numbers MK462LL/A, MK472LL/A or MK482LL/A. The system must accept DDR3L 1.35V unbuffered non-ECC SODIMMs with 204 pins. Machines with different identifiers or order numbers may not recognise these modules.

Sustained workloads run at rated 1866 speed

Under continuous load the modules operate at the specified DDR3 1866/1867 MHz (PC3-14900) frequency using major-brand chips. The 2Rx8 rank organisation and 1.35V voltage remain stable during extended multitasking or memory-intensive applications. No heat spreader is fitted, so airflow inside the iMac chassis handles thermal management.

商品問答

Does the kit include both 16 GB modules or do I need to buy a second stick separately?

The kit contains two 16 GB modules for a total of 32 GB, so no additional sticks are required.

Should I choose the 32 GB kit or a smaller capacity for my iMac 17,1?

The 32 GB kit matches the maximum supported memory for the iMac 17,1 and uses the specified DDR3L 1866 speed.

Will the DDR3L 1866 speed run at 1866 MHz once installed in my Late 2015 iMac?

Yes, the modules are rated at DDR3L 1866 (PC3L 14900) and will operate at that speed in the compatible iMac.
