32GB DDR3 SO-DIMM kit for Apple iMac A1311

This 32 GB kit contains four 8 GB DDR3 1333 MHz SO-DIMM modules built to the PC3-10600 standard. The unbuffered non-ECC memory runs at 1.5 V with CL9 9-9-9 timings and uses 204-pin connectors. It is specified for the Apple iMac 21.5 inch Intel Core i7 2.8 GHz model A1311.

Fits four SO-DIMM slots in the target iMac

The kit populates all four memory sockets of the compatible iMac, delivering the maximum 32 GB capacity that the system accepts. No heat spreaders are fitted, so the low-profile modules clear the tight internal space of the all-in-one chassis. Installation requires no additional components beyond the factory memory slots.

Sustained throughput at rated JEDEC speeds

Under continuous load the modules operate at their rated 1333 MHz frequency and 1.5 V without overclocking headroom. The CL9 latency and 2Rx8 organisation provide stable bandwidth for long rendering or virtualisation sessions. Builders needing ECC error correction or higher DDR generations must choose a different product.

Questions about this item

What is the maximum total memory capacity this 32GB kit will bring the iMac 21.5" A1311 to?

The kit provides 32GB total across four 8GB modules, matching the 32GB maximum memory limit for the iMac 21.5" Intel Core i7 2.8GHz A1311.

How much power does each 8GB module draw at the rated 1.5V voltage?

Each DDR3 SODIMM operates at 1.5V; typical power draw for an 8GB 1333MHz module at this voltage is low and well within the iMac's SO-DIMM slot limits.

Does the iMac 21.5" A1311 require any specific memory configuration for all four slots to be recognised?

The iMac 21.5" A1311 has four SO-DIMM slots and supports 8GB modules in each slot; this 4x8GB kit fills all slots for the full 32GB capacity.
