System-specific DDR2 kit

This 4 GB kit contains two 2 GB DDR2 SO-DIMMs rated at 800 MHz with CL6 timing. It is built for the Apple iMac Core 2 Duo 2.8 24-Inch Early 2008 and uses unbuffered non-ECC modules. The 200-pin form factor matches the original memory slots exactly.

Fits the original slots

Two SO-DIMM sockets accept this matched pair without adapter brackets or voltage changes. The 1.8 V modules run at the standard DDR2 6400 data rate and free both slots for the maximum supported capacity. No heat spreaders are fitted so clearance inside the slim all-in-one chassis is preserved.

Steady CL6 operation

Rated timings of 6-6-6 hold across sustained workloads because the major-brand chipset and unbuffered design avoid extra latency stages. The 2Rx8 organisation keeps each rank active during long sessions without registered buffering overhead. Lifetime warranty from the manufacturer covers defects for the usable life of the system.

Questions about this item

Will the 1.8 V DDR2 modules overheat during all-day use?

The kit runs at standard 1.8 V with no heat spreader; DDR2 SO-DIMMs at this voltage typically stay within safe thermal limits inside the iMac's existing airflow.

How loud is the memory under continuous load?

SO-DIMM modules have no moving parts, so they add no audible noise; any sound comes from the iMac's own cooling fans.

Does the Early 2008 24-inch iMac need a firmware update before installing this 200-pin DDR2 800 MHz kit?

The modules are built to the exact DDR2 800 specification Apple used in that model, so they work without a separate firmware step.
