Matched kit for 21.5" iMac Mid-2010

This 8 GB kit contains two 4 GB DDR3 SO-DIMMs rated at 1333 MHz with CL7 timings and 1.5 V operation. The modules are unbuffered, non-ECC and built with major-brand chips on a 204-pin form factor. They are validated for the Apple iMac "Core i3" 3.06 21.5-inch (Mid-2010) and ship as a matched pair for dual-channel performance.

Who this suits and who it does not

Ideal for owners of the specified Mid-2010 21.5-inch iMac who want a straightforward capacity increase to 8 GB using the correct DDR3 SO-DIMM type. Not suitable for systems that require ECC or registered memory, for any other iMac screen size or year, or for platforms that use a different DDR generation or pin count.

The specification that decides fit

The decisive factor is the 204-pin DDR3 SO-DIMM interface running at 1333 MHz (PC3 10600) with CL7 latency at 1.5 V. If the target Mac calls for this exact module type, speed and voltage, the kit will install and run; if the system demands a different pin layout, voltage or DDR generation, the modules will not be compatible.

Questions about this item

How can I verify the kit is running at the rated 1333 MHz CL7 after installing it in my iMac?

Open About This Mac → System Report → Memory and confirm each slot shows 4 GB DDR3 at 1333 MHz; the CAS latency will be reported as 7-7-7 timing.

What exactly ships in the box and is anything else required for the upgrade?

The package contains two 4 GB 204-pin DDR3 SO-DIMM modules; no extra tools or parts are needed for the Mid-2010 iMac memory slots.

Which capacity kit should I choose if my iMac 21.5-inch Mid-2010 currently has 4 GB installed?

This 8 GB (2 × 4 GB) kit replaces the existing pair and matches the model MC508LL/A specification for a full 8 GB upgrade.
