Targeted iMac upgrade
This 4 GB kit (2 × 2 GB) uses 200-pin DDR2 SO-DIMM modules rated at 800 MHz (PC2-6400) with CL6 timings. It is built specifically for the Apple iMac "Core 2 Duo" 2.4 20-Inch Early 2008 (model identifiers MB323LL/A, iMac8,1, A1224). The unbuffered, non-ECC design matches the original factory specification.
Sustained load behaviour
At the rated 1.8 V the modules maintain their 6-6-6 timings continuously without dropping to lower speeds. The major-brand chipset and 2Rx8 organisation keep data integrity stable during long work sessions. The system maximum of 6 GB across the two sockets means this kit leaves one slot free for a further 2 GB module if required.
Thermals noise power
With no heat spreader fitted, the sticks rely on the iMac's internal airflow for cooling. Power draw stays at the standard DDR2 1.8 V level, adding minimal load to the power supply. Silent operation is assured because the memory produces no audible noise and does not trigger extra fan activity under normal use.

商品問答
How much heat and power does this 1.8V DDR2 kit draw during all-day use?
The modules run at the standard DDR2 voltage of 1.8V without a heat spreader, so they add minimal warmth and draw only the power the iMac memory controller supplies.
What must my iMac already have for these two 200-pin SO-DIMMs to install and boot?
Your Apple iMac "Core 2 Duo" 2.4 20-Inch Early 2008 needs two free SO-DIMM slots and a firmware that recognises PC2-6400 CL6 unbuffered memory.
Will this PC2-6400 CL6 pair work with the original memory sticks already in the iMac?
Computer Memory Solutions guarantees compatibility with the specified iMac model; the kit is tested to run alongside the factory-installed modules in that system.
