iMac Mid-2010 21.5-inch memory kit

This 4 GB kit contains two 2 GB DDR3 1333 SO-DIMM modules built for the Apple iMac "Core i3" 3.2 21.5-inch (Mid-2010) MC509LL/A. The unbuffered, non-ECC sticks run at 1.5 V with CL7 7-7-7 timing and use 204-pin connectors. Computer Memory Solutions backs the kit with a limited lifetime warranty when purchased directly from them.

Suitable for the specified 21.5-inch Mid-2010 iMac

Owners of that exact model can install both modules to reach 4 GB total capacity. Buyers with any other iMac size, year, or Mac model cannot use this kit. Systems that require ECC, registered, or lower-voltage DDR3 memory are also incompatible.

204-pin DDR3 1333 SO-DIMM form factor

The 204-pin SO-DIMM edge connector and DDR3 1333 (PC3-10600) signalling determine whether the modules physically fit and function in the target iMac. Verify the 204-pin DDR3 requirement before ordering.

Questions about this item

Will the 1333 MHz speed run at full rate in the Mid-2010 iMac?

The iMac's memory controller supports 1333 MHz DDR3, so both 2 GB modules will operate at their rated PC3-10600 speed without down-clocking.

Does the 204-pin SO-DIMM form factor match the iMac's slots?

Yes, the kit uses standard 204-pin DDR3 SO-DIMMs, which are the exact module type required by the four memory slots in the 21.5-inch Mid-2010 iMac.

How many sticks are included and will they fit the available slots?

The package contains two 2 GB sticks, leaving two of the four SO-DIMM slots free for future expansion up to the 16 GB maximum.
