Ready-to-install kit for specific iMacs

This 8 GB kit contains two 4 GB DDR3 1333 MHz SO-DIMMs built to the PC3-10600 standard. They run at 1.5 V with CL7 7-7-7 timing and use unbuffered, non-ECC chips on a 204-pin form factor. The modules are validated for the Apple iMac Core i3, i5 and i7 models listed by the manufacturer.

Fits 2010 iMacs with four SO-DIMM slots

The memory is qualified for the 21.5 inch and 27 inch Intel Core i3, i5 and i7 iMacs released in mid-2010 that support up to 16 GB across four sockets. It will not work in laptops or desktops that require a different pin count, voltage or DDR generation, nor in systems that demand ECC or registered memory.

204-pin DDR3 SO-DIMM interface

The single specification that decides fitment is the 204-pin DDR3 SO-DIMM interface running at PC3-10600 speed. If the target machine uses that exact slot and signalling standard, the kit installs directly; otherwise the modules are physically and electrically incompatible.

Questions about this item

My iMac has four SO-DIMM slots — can I add this 2×4GB kit alongside the two 2GB modules already installed?

Yes — the Mid 2010 iMacs listed have four slots and a 16GB maximum, so adding this 8GB kit to an existing 4GB gives 12GB total, well within the limit.

Does the 1.5V requirement match the voltage used by Mid 2010 iMac memory slots?

The modules are standard 1.5V DDR3 SO-DIMMs, which is the voltage those iMac models expect for unbuffered non-ECC memory.

After installing the pair, how can I confirm both 4GB sticks are recognised at 1333MHz CL7?

Open About This Mac → System Report → Memory; you should see two 4GB DIMMs listed at 1333MHz with a CAS latency of 7.
