16 GB DDR3L kit for 27-inch iMac Mid 2014

This 16 GB kit contains two 8 GB SODIMM modules built for the 27-inch iMac with a 3.4 GHz quad-core Intel Core i5 from Mid 2014. Each stick is a 204-pin DDR3L 1600 unit rated at PC3L 12800. The memory runs at 1.35 V with CL11 timings. It is unbuffered, non-ECC and uses a 2Rx8 rank configuration. The kit is designed as a direct drop-in upgrade for the specified iMac.

Two matched modules enable dual-channel operation

The package supplies two identical 8 GB sticks so the iMac can run in dual-channel mode, which the four-slot board supports up to a total of 32 GB. A major-brand chipset is used on each module and no heat spreader is fitted, keeping the low-profile form factor required by the all-in-one chassis. Computer Memory Solutions guarantees compatibility with the listed model and backs the kit with a limited lifetime warranty when purchased directly from them.

DDR3L 1600 at 1.35 V is the decisive spec

The iMac Mid 2014 requires DDR3L SODIMMs at 1600 MHz and 1.35 V; standard 1.5 V DDR3 modules are not compatible and will not work. Buyers whose systems need a different voltage, speed, pin count or form factor cannot use this kit. The 204-pin DDR3L 1600 specification is the single figure that determines fit.

Questions about this item

Will the 2Rx8 DDR3L modules need any firmware updates or re-seating after the iMac 27-inch Mid 2014 runs for a while?

The 2Rx8 DDR3L SODIMMs are unbuffered and non-ECC with CL11 timing at 1.35 V. They install in the four 204-pin slots and require no firmware updates or periodic re-seating under normal use.

What limit appears first when the iMac 27-inch Mid 2014 runs sustained workloads with this 16 GB kit installed?

The iMac 27-inch Mid 2014 supports a maximum of 32 GB across its four slots. With this 16 GB (2 x 8 GB) kit you still have two free slots, so the memory ceiling is not reached until you populate all four sockets.

How much extra heat or fan noise should I expect from the 1.35 V DDR3L 1600 MHz sticks during all-day operation?

The modules run at the standard DDR3L 1.35 V with no heat spreader. They add minimal thermal load, so the iMac’s existing cooling handles all-day operation without noticeable fan-speed increase.
