System-Specific DDR2 Upgrade

This 4 GB kit contains two 2 GB DDR2-667 SO-DIMM modules built for the Apple iMac 20-inch 2.16 GHz Intel Core 2 Duo (MA589LL). The unbuffered, non-ECC memory runs at 1.8 V with CL5 5-5-5 timings and uses 200-pin connectors. It is intended for owners of that exact iMac model who want to reach the system’s 4 GB maximum.

Check Your iMac Model First

Verify that your iMac is the 20-inch 2.16 GHz Intel Core 2 Duo variant identified by Apple part numbers MA346G/A, MA837G/A or MA589LL. This kit only fits machines that accept 200-pin DDR2 SO-DIMMs running at 667 MHz (PC2-5300). Other iMac sizes, speeds or generations use different memory and will not accept these modules.

Fills Both Slots for Full Capacity

The iMac 20-inch 2.16 GHz has two SO-DIMM sockets supporting a total of 4 GB. Installing this matched pair occupies both slots and delivers the maximum addressable memory for the platform. No further modules can be added once the kit is in place, so the upgrade is complete in a single step.

商品問答

What comes in the box with the CM256645300SO kit and is anything else needed?

The package includes two 2 GB DDR2 667 MHz SODIMM sticks for a total of 4 GB. No extra parts or cables are required for installation.

Should I choose the 2×2 GB kit or look for a single 4 GB module for the iMac 20-inch 2.16 GHz?

The iMac uses two memory slots, so the matched 2×2 GB kit fills both slots and enables dual-channel operation for the best performance.

What does the PC2-5300 667 MHz rating mean once the modules are installed in the iMac?

The memory will run at 667 MHz with CL5 timing at 1.8 V, giving the maximum supported bandwidth for this model.
