Tailored for 27-inch iMac Mid-2011

This 8 GB kit delivers two 4 GB DDR3 1333 SO-DIMM modules built specifically for the Apple iMac "Core i7" 3.4 27-Inch (Mid-2011). It targets owners of that exact all-in-one who need to restore or expand system memory without guessing compatibility. Unbuffered, non-ECC sticks with CL7 timing match the original specification.

Fills two of four available slots

The computer accepts up to 32 GB across four sockets, so this pair occupies half the capacity while leaving room for further upgrades. Each module uses a 204-pin edge connector and standard 1.5 V operation, requiring no special cooling or voltage adjustment. Installation follows the standard user-accessible memory door procedure.

Low-profile modules run at standard voltage

Without heat spreaders, the sticks rely on the iMac's internal airflow, which is designed for bare SO-DIMMs at 1333 MHz. Power draw stays within the factory memory budget, and the CL7 7-7-7 timing keeps latency tight for everyday workloads. No additional fan noise or thermal headroom is needed beyond the stock cooling solution.

商品問答

Will the CL7 timing hold under sustained load without throttling?

The modules run at CL7 7-7-7 timings at 1333 MHz with 1.5 V, so the rated latency is maintained as long as the iMac cooling keeps the memory within its thermal envelope.

How much heat and noise do the sticks add during all-day use?

The SO-DIMMs have no heat spreader and draw standard 1.5 V DDR3 power; they add negligible heat and make no noise, relying on the iMac's existing airflow.

Which iMac models must I already own for this kit to work?

The kit is validated for the Apple iMac "Core i7" 3.4 27-Inch (Mid-2011) identifiers iMac12,2 and A1312 with four SO-DIMM slots supporting up to 32 GB total.
