A-Tech 32GB (4x8GB) DDR3L 1866 SODIMM 204-Pin Memory Upgrade
A 32 GB DDR3L 1866 MHz SODIMM kit for upgrading compatible 2015 Apple iMac models
- Capacity32GB (4 x 8GB)
- SpeedDDR3L 1866 (PC3L 14900)
- Voltage1.35V
- ECCNo
- Buffered/RegisteredUnbuffered
- Rank2Rx8
- 32 GB total capacity for demanding multitasking across four 8 GB modules
- DDR3L 1866 MHz speed matches Late 2015 iMac specifications
- 35 V low-voltage operation reduces power draw and heat
- 204-pin SO-DIMM form factor fits Apple iMac (Retina 5K, 27-inch, Late 2015)
- Non-ECC unbuffered 2Rx8 design validated for macOS stability
Target system
This 32 GB kit is built for the Apple iMac (Retina 5K, 27-inch, Late 2015) with model ID iMac17,1 and order numbers MK462LL/A, MK472LL/A and MK482LL/A. It fills all four SO-DIMM slots with matched 8 GB modules.
Sustained workload behaviour
DDR3L 1866 runs at 1.35 V, so the modules generate less heat than standard-voltage DDR3 during long multitasking sessions. The 2Rx8 unbuffered design keeps latency stable when the system is pushing large datasets through all 32 GB.
Installation notes
Each stick is a 204-pin SO-DIMM that slides into the iMac's bottom memory door; no tools are required beyond a screwdriver for the access panel. The only common issue is inserting a module at an angle, which prevents the retention clips from engaging fully.

שאלות על הפריט הזה
How much power does the 1.35V DDR3L kit draw when the iMac runs all day?
Each 8 GB module operates at 1.35 V, so the four-module kit runs cooler and draws less power than standard 1.5 V DDR3 during sustained workloads.
Which iMac models must I already own for this 204-pin SODIMM kit to fit?
The kit is validated for iMac (Retina 5K, 27-inch, Late 2015) with model ID iMac17,1 and order numbers MK462LL/A, MK472LL/A, MK482LL/A.
Will the 1866 MHz modules down-clock automatically if my Late 2015 iMac originally shipped with slower DDR3?
Yes, the DDR3L 1866 modules will run at the highest speed the iMac's memory controller supports, matching the original specification without manual setup.
