8 GB DDR3 SO-DIMM kit for Mid-2010 iMac

This 8 GB kit contains two 4 GB DDR3 1333 MHz modules built to the PC3-10600 standard. They use 204-pin SO-DIMM form factor, run at 1.5 V with CL7 timings and are unbuffered non-ECC. The kit is specified for the Apple iMac "Core i3" 3.2 27-Inch (Mid-2010) MC510LL/A.

Suits owners of that exact iMac model wanting

The iMac ships with 4 GB across two slots and has four sockets total. This kit occupies the two free slots and raises the total to 12 GB. It will not help builders working on other platforms, laptops needing different speeds or voltages, or anyone needing ECC or registered memory.

Fits the two vacant SO-DIMM sockets inside

Installation requires access to the memory compartment behind the lower edge of the display. No heat spreaders are fitted, so standard clearance applies. The upgrade leaves the original pair in place and uses the remaining capacity headroom.

Questions about this item

Does my iMac need four empty SO-DIMM slots to use this 2×4 GB kit?

The Mid-2010 27-inch iMac has four slots; two are occupied by the factory 2×2 GB modules, so the two free slots accept this kit directly.

Will these CL7 modules run at CL7 alongside the original CL9 memory?

The system operates all modules at the slowest common timing, so the original CL9 sticks set the pace and the CL7 kit will run at CL9.

How can I confirm the kit is recognised at 1333 MHz after installation?

Open About This Mac → Memory; it should show 8 GB total (4 GB + 4 GB) at 1333 MHz DDR3.
