In this video I upgrade the Apple iMac 21.5-inch Core i5 Mid 2010 from 4GB to 8GB of RAM. This is performed using a Crucial Technology Memory Upgrade Kit.
Crucial Technology also gave some insight into how memory upgrades can effect Mac performance...
While synthetic benchmarks are a great way to measure certain aspects, they don't always capture what the desired outcome of a memory upgrade is, being increased system performance and a better user experience. In actual use, 8GB of RAM with 64-bit operating systems allows more, and larger, applications to be run entirely from RAM at an access latency of under 20ns, whereas accessing data on the hard drive can have access latencies in excess of 4 million nano-seconds. The result being a much better user experience, snappier UI and overall increased productivity.
