Targeted iMac upgrade

This 8 GB kit delivers two 4 GB DDR3 SO-DIMMs built for the 20-inch iMac with a 2.66 GHz Core 2 Duo from early 2009. The modules match the factory PC3-8500 specification and install directly into the two available slots.

Low-voltage operation

Running at 1.5 V with CL7 7-7-7 timing, the unbuffered non-ECC sticks draw minimal power and produce no audible noise because they have no moving parts. The major-brand chipset and 2Rx8 organisation keep thermals modest inside the compact all-in-one chassis.

Steady sustained throughput

Under continuous workloads the memory maintains its rated 1066 MHz speed without throttling, so rendering, virtualisation or large media libraries see consistent bandwidth. Builders needing more than 8 GB or a different form factor should look elsewhere.
