4GB DDR2 SODIMM for 20-Inch iMac

This 4 GB DDR2 800 MHz module is built specifically for the Apple iMac Core 2 Duo 2.4 20-Inch Early 2008. It installs as a single 200-pin SO-DIMM running at 1.8 V with CL6 timing. The part is new and carries the manufacturer's lifetime warranty when purchased direct.

Suits owners of the listed iMac model

Buyers with a different iMac year, screen size, or processor speed should verify their exact model identifier before ordering. Systems that require ECC or registered memory cannot use this unbuffered stick. The kit contains only one module, so a second slot must be filled separately to reach the 6 GB maximum.

DDR2 800 (PC2-6400) 200-pin SO-DIMM

The module operates at DDR2 800 speed, also labelled PC2-6400, and fits the 200-pin SO-DIMM socket in the compatible iMac. It is a 2Rx8 rank, non-ECC, unbuffered design without a heat spreader. Confirm the system accepts 1.8 V DDR2 before purchase.

Questions about this item

Should I pick the single 4 GB module or add a second stick to reach the 6 GB maximum?

The iMac has two slots and supports up to 6 GB total; installing this 4 GB stick leaves one slot free for an additional 2 GB module if you want the full capacity.

What does the 800 MHz rating deliver in everyday use on this iMac?

Running at 800 MHz with CL6 timing, the module matches the memory controller speed of the 2.4 GHz Core 2 Duo, so the system can sustain its peak bandwidth without down-clocking.

How does the 200-pin DDR2 SO-DIMM interface limit performance?

The 200-pin DDR2 SO-DIMM interface is keyed for PC2-6400 operation at 1.8 V, so the module cannot run faster than 800 MHz or use tighter timings than the rated CL6.
