Targeted Mac Memory Upgrade

This 16GB kit uses two 8GB DDR3 SODIMM modules built for the 27-inch iMac models released between 2012 and 2015. It matches the factory PC3-12800 1600MHz specification so the system recognises the full capacity immediately. The unbuffered non-ECC design matches the original Apple memory architecture. Owners of other Macs or PC laptops should verify their exact model requirements before purchasing.

Direct Fit SODIMM Format

Each module uses the standard 204-pin DDR3 SODIMM edge connector that slides into the iMac memory slots without adapters. The 1.35V operating voltage matches the low-voltage specification Apple used in these all-in-one desktops. Major-brand DRAM from Samsung Micron or Hynix is used depending on production batch. There is no heat spreader so the modules sit flush in the tight SO-DIMM bays.

Low Voltage Cool Operation

Running at 1.35V keeps power draw and heat output low inside the sealed iMac chassis. The CL11 latency at 1600MHz delivers responsive everyday performance for multitasking and creative workloads. Passive cooling is sufficient because the modules generate minimal thermal load. The kit is validated for stable operation under sustained workloads typical of these workstation-class Macs.

商品問答

What speed does the DDR3 1600MHz SODIMM kit run at in a 27-inch iMac?

The modules operate at DDR3 1600 (PC3-12800) with CL11 latency at 1.35V, the native speed supported by the 2012–2015 iMac memory controller.

Will the 204-pin modules fit the memory slots in a 27-inch iMac from 2012 to 2015?

Yes, the 204-pin DDR3 SODIMM form factor matches the four SO-DIMM slots accessible behind the rear cover on those iMac models.

How do you install the kit in a 27-inch iMac and what step is often missed?

Power off, unplug, lay the iMac face-down on a soft cloth, remove the memory access door, eject the old modules by spreading the side clips, insert each new SODIMM until the clips click, replace the door, then reconnect power.
