Target system
This A-Tech 8GB kit is built for the Apple iMac Retina 5K 27-inch Late 2015 and matches the factory specifications for that machine. It delivers two 4GB DDR3L SODIMM modules rated at 1866 MHz with a low 1.35 V operating voltage. The memory uses unbuffered non-ECC chips in a 1Rx8 organisation and carries the Apple order numbers MK462LL/A, MK472LL/A and MK482LL/A for direct compatibility.
Who this suits
The kit is intended for owners of the iMac model identifier iMac17,1 who want to populate both SODIMM slots with matched capacity. Buyers needing a single module, a different total capacity, ECC error correction, registered buffering, a higher or lower voltage, or a different pin count will not be served by this specific part. The 204-pin form factor and DDR3L signalling limit use to platforms designed for that exact combination.
Deciding specification
The critical figure is DDR3L 1866 (PC3L 14900) at 1.35 V in a 204-pin unbuffered non-ECC SODIMM. Only systems that specify this exact speed, voltage, pin layout and ECC type will accept the modules without instability or physical mismatch.

이 상품에 대한 질문
Should I pick this 8GB kit with two 4GB modules instead of a single 8GB stick?
This kit contains two 4GB modules for dual-channel operation on the iMac (Retina 5K, 27-inch, Late 2015), model ID iMac17,1 and EMC 2834.
What does the 1866 MHz speed mean once installed in my iMac?
The DDR3L 1866/1867 MHz (PC3-14900) rating matches the memory controller specification for the compatible iMac models, allowing the system to run at its designed memory bandwidth.
Will the 204-pin DDR3L SODIMM fit and run at the correct voltage in my Mac?
Yes, the modules are 204-pin DDR3L SODIMMs operating at 1.35V, which is the correct form factor and voltage for the supported Apple iMac (Late 2015) systems.
