16 GB DDR3 kit for 21.5-inch iMac Mid-2010

This 16 GB kit contains four 4 GB DDR3 1333 MHz SO-DIMM modules built for the 21.5-inch iMac Mid-2010 with a 3.6 GHz Core i5 processor. It fills all four memory slots and reaches the model's 16 GB maximum capacity. The unbuffered, non-ECC design matches the original specification.

Four matched modules remove mixing risk

The kit supplies four identical 204-pin sticks rated at CL7 7-7-7 timing and 1.5 V. Because every module comes from the same production batch, the memory controller sees uniform electrical characteristics. This avoids the instability that can appear when different ranks or latencies are combined in the four-slot layout.

Straightforward slot access with one common pitfall

The SO-DIMM slots are reached by removing the bottom access door on the iMac, requiring only a Phillips screwdriver. Each module keys into its 204-pin socket in one orientation. The frequent mistake is not pressing firmly enough until the side clips click, which leaves the stick partially seated and causes a boot failure.

商品問答

Will the 204-pin DDR3 SODIMM modules need any firmware updates or pairing after installation?

No firmware updates or pairing are required; the four 4 GB sticks install directly into the four SO-DIMM slots of the Mid-2010 iMac and are recognised immediately.

What thermal limit appears first when the 1.5 V CL7 kit runs continuously in the 21.5-inch iMac?

The iMac's internal airflow becomes the limiting factor; the memory itself has no heat spreader, so sustained loads raise case temperature until the system throttles.

How much power does the 16 GB DDR3 1333 MHz kit draw when the iMac is under all-day load?

Each 4 GB module operates at 1.5 V, so the full 16 GB set draws roughly 8–10 W total under continuous use.
