4GB DDR2 667 SODIMM for Apple iMac 20-Inch

This Computer Memory Solutions module provides 4GB of DDR2 667 memory in a 200-pin SO-DIMM format. It is built as an unbuffered, non-ECC stick with CL5 timing and operates at 1.8V voltage. The part is verified for the Apple iMac Intel Core 2 Duo 2.4 20-Inch Aluminum model.

Suits owners upgrading that specific iMac

Buyers with a different iMac model or any non-Apple system should verify their exact memory requirements before ordering. This module will not serve users needing ECC error correction or registered memory configurations.

200-pin DDR2 SO-DIMM interface

The 200-pin DDR2 SO-DIMM form factor running at PC2-5300 667MHz is the decisive specification for installation. Only systems accepting this exact interface and speed will recognise and use the module correctly.

Questions about this item

Does this 200-pin DDR2 SODIMM fit the Apple iMac Intel Core 2 Duo 2.4 20-inch aluminum model listed in the compatibility notes?

Yes, the module is specified as compatible with that exact iMac model and uses the 200-pin DDR2 SODIMM form factor it requires.

Can this 4 GB stick be used in the second slot while a 2 GB module remains in the first slot to reach the 6 GB maximum?

The iMac supports up to 6 GB by pairing one 4 GB and one 2 GB module, so this stick can occupy the free slot alongside an existing 2 GB module.

How can I confirm the memory is detected at 667 MHz with CL5 timing after installation?

Open System Profiler or About This Mac and check that the slot shows 4 GB DDR2 667 MHz with 5-5-5 latency values.
