iMac Mid-2011 27-Inch Memory Kit

This 16 GB kit contains two 8 GB DDR3 1333 MHz SODIMM modules built to the PC3-10600 standard. The unbuffered, non-ECC sticks run at 1.5 V with CL9 timing and use 204-pin connectors. They are intended as a direct RAM upgrade for the specified Apple all-in-one desktop.

Suits owners of the named iMac model

The kit matches the Apple iMac "Core i5" 2.7 27-Inch (Mid-2011) identifiers MC813LL/A, iMac12,2 and A1312. Apple officially supports 16 GB in this system; the supplier notes the practical maximum may reach 32 GB across four slots. Buyers with any other Mac model, a different screen size, a Windows laptop or a desktop motherboard should look elsewhere because the pin layout, voltage and firmware expectations differ.

204-Pin DDR3 1333 MHz SODIMM Form Factor

The modules must fit a 204-pin DDR3 SO-DIMM socket operating at 1333 MHz (PC3-10600). If the target machine uses a different pin count, a different DDR generation or a different voltage, the sticks will not seat or will not be recognised. Verify the exact iMac model and slot specification before purchase.

商品問答

Does the 1333 MHz DDR3 speed limit bandwidth before the iMac 27-Inch Mid-2011 processor does?

The modules run at 1333 MHz DDR3, which matches the iMac 27-Inch Mid-2011 memory controller specification, so the memory bus is not the first bottleneck under sustained load.

How much heat do two 1.5 V DDR3 SODIMMs add when the iMac runs all day?

Each stick operates at 1.5 V without a heat spreader; the iMac's internal airflow is designed for this power level, so temperatures stay within the system's normal range during continuous use.

Must the iMac 27-Inch Mid-2011 already have four empty SODIMM slots for this 2 x 8 GB kit to work?

The iMac 27-Inch Mid-2011 has four SODIMM slots and a 32 GB maximum; the 2 x 8 GB kit occupies two slots and works whether the other two are empty or already populated with compatible DDR3 modules.
