System-Specific 16 GB DDR3 Kit

This 16 GB kit contains four 4 GB DDR3-1333 SO-DIMM modules built for the 27-inch iMac released in mid-2011. It targets owners of that specific model who want to populate all four memory slots with matched parts.

204-Pin DDR3 SO-DIMM at 1333 MHz

The decisive specification is the 204-pin DDR3 SO-DIMM form factor running at 1333 MHz (PC3-10600). Only systems that accept this exact module type and speed will recognise the memory; other generations or pin counts will not fit.

Fills Four Slots for 16 GB Total

The kit delivers 16 GB across the iMac’s four sockets, reaching half of the machine’s 32 GB maximum. It suits everyday workloads and moderate multitasking; users needing the full 32 GB ceiling must add higher-capacity modules instead.

Questions about this item

What does the 16 GB kit actually give me inside a 27-inch Mid-2011 iMac?

Four 4 GB SO-DIMMs fill all four slots, raising the iMac to its 16 GB total using DDR3-1333 CL7 modules.

How does the PC3-10600 rating limit real-world throughput?

PC3-10600 caps the modules at 1333 MT/s on the iMac's DDR3 controller, so peak bandwidth is limited to that standard.

Will these 204-pin sticks physically seat in the 27-inch Mid-2011 iMac memory bay?

Yes — they are 204-pin DDR3 SO-DIMMs, the exact form factor the iMac's four SO-DIMM slots require.
