Targeted iMac memory upgrade

This 8 GB kit uses two 4 GB DDR3 1066 modules built for the 27-inch iMac with a 3.06 GHz Core 2 Duo. It suits owners of that specific model who need the maximum factory-supported memory for everyday tasks and older macOS versions.

DDR3 1066 bandwidth ceiling

The PC3-8500 standard caps data rate at 1066 MT/s, so throughput cannot exceed what the memory controller allows. The iMac’s chipset does not run faster DDR3 speeds, and the four SO-DIMM slots limit total capacity to the amount this kit provides.

Replaces slower or smaller factory modules

Upgrading from the original 2 GB or 4 GB configurations removes the memory bottleneck that causes swapping in multi-app workflows. The jump is worthwhile when the system still serves as a daily driver for legacy software that runs on the supported macOS releases.
