16GB DDR3 SO-DIMM kit for 2011 iMac

This 16GB kit contains four 4GB DDR3 1333MHz CL7 SO-DIMM modules built for the Apple iMac "Core i3" 3.1 21.5-Inch (Late 2011). The unbuffered, non-ECC memory runs at 1.5V and uses 204-pin DDR3 SO-DIMM form factor to fill all four available slots.

Replaces lower-capacity DDR3 modules when 16GB is

The iMac12,1 platform caps total memory at 16GB across four sockets, so this kit is the maximum upgrade path. It is worth installing when the machine currently runs less than 16GB and the workload benefits from the full addressable space, such as larger datasets or heavier multitasking within the OS version the hardware supports.

Sustained operation at CL7 1.5V without heat

The modules operate at CL7 7-7-7 timings and 1.5V continuously. Because they lack heat spreaders, airflow inside the iMac chassis determines thermal behaviour during prolonged use; the memory will maintain rated speed as long as the system cooling keeps component temperatures within DDR3 limits.

商品問答

Does the 204-pin SO-DIMM form factor match the memory slots in the Late 2011 21.5-inch iMac?

Yes, the kit uses 204-pin DDR3 SO-DIMMs which are the correct module type for the iMac "Core i3" 3.1 21.5-Inch (Late 2011) that has four SO-DIMM slots.

Do I need to install all four 4GB modules at once, or can I add them one at a time?

The iMac has four slots and supports a maximum of 16GB; you can install the modules one at a time, but the full 16GB capacity is only reached when all four 4GB sticks are populated.

Will the 1.5V operating voltage require any future adjustment or replacement?

No, the modules run at the standard 1.5V for DDR3 and have no heat spreader or moving parts, so no voltage adjustments or component replacements are needed during their service life.
