16GB DDR3 kit for 2010-2011 iMac

This 16GB kit contains four 4GB DDR3 1333MHz SODIMM modules built for specific Apple iMac models from Mid 2010 and Mid-to-Late 2011. It uses unbuffered non-ECC memory with a 2Rx8 rank configuration and runs at 1.50V. The kit matches Apple order numbers including MC309LL/A, MC812LL/A through MC814LL/A, and MD063LL/A.

Suits owners of listed 21.5-inch and 27-inch iMacs

The modules are validated for iMac model identifiers iMac11,2, iMac11,3, iMac12,1 and iMac12,2 covering EMC numbers 2389, 2390, 2428 and 2429. Buyers with iMacs outside these model years or identifiers should verify compatibility before purchasing. Systems requiring ECC or registered memory cannot use this kit.

204-pin DDR3 1333MHz SODIMM form factor

The memory uses the 204-pin SO-DIMM form factor operating at DDR3 1333MHz (PC3-10600). This physical interface and signalling standard determines whether the modules fit and function in the target iMac slots.

商品問答

Will the 204-pin SODIMM modules need replacement after years of 1.50V operation?

These DDR3 modules run at the standard 1.50 volts and are unbuffered non-ECC; they have no moving parts and A-Tech backs them with a lifetime warranty.

What limit appears first when all four 4GB sticks run at 1333 MHz continuously?

The iMac memory controller caps total capacity at 16 GB, so the 4×4 GB kit already hits that ceiling before bandwidth or heat become bottlenecks.

How much extra heat or fan noise does the 16 GB kit add during all-day workloads?

The modules lack heat spreaders and draw standard DDR3 power, so the iMac’s existing cooling handles the load without audible fan-speed changes.
