8GB DDR3L kit for 27-inch iMac

This 8GB kit contains four 2GB SODIMM modules built to the DDR3L 1600MHz PC3L-12800 specification at 1.35V. It is engineered for the 27-inch iMac models released from Late 2012 through Mid 2015, including the Retina 5K versions. The unbuffered non-ECC design matches the factory memory architecture used in these all-in-one desktops.

Steady throughput for everyday workloads

Major-brand chips are tested to meet JEDEC standards so the modules maintain their rated speed during extended multitasking sessions. The low-voltage DDR3L operation keeps heat output modest inside the compact iMac enclosure, allowing sustained performance without thermal throttling under typical creative and office workloads.

Four-slot installation with model verification

All four SO-DIMM slots must be populated for this kit, so remove any existing modules before fitting the new set. Confirm the iMac model identifier (iMac13,2, iMac14,2 or iMac15,1) and order number against the compatibility list to avoid a mismatch. Buyers needing a smaller upgrade or a different DDR generation cannot use this kit.

商品問答

How much heat and power will the 1.35 V DDR3L modules generate when the iMac runs all day?

The kit runs at 1.35 V DDR3L voltage, which is lower than standard DDR3, so each 2 GB module produces less heat and draws less power during continuous operation.

What must the iMac already have for these 204-pin SODIMMs to work?

Your 27-inch iMac (Late 2012, Late 2013, Late 2014 or Mid 2015) needs four empty SO-DIMM slots; the kit includes four 2 GB modules that fill every slot.

Will the 1600 MHz DDR3L memory run correctly alongside the original Apple memory in a Late 2012 iMac?

Yes, the modules are DDR3 1600 MHz PC3-12800, matching the speed and voltage Apple specifies for the Late 2012 through Mid 2015 27-inch models, so they operate together without downclocking issues.
