Memory

The more memory your computer has, the more apps you can run simultaneously, and the better performance you get from your computer. Your iMac uses one of the fastest memory technologies available today — 1600MHz, Double Data Rate (DDR3) synchronous dynamic random-access memory (SDRAM) — ensuring that the processor is constantly fed with data without wasting clock cycles.

  • Select the standard memory configuration to support day-to-day tasks such as email, word processing and web browsing, as well as more complex tasks such as editing photos, creating illustrations and building presentations.
  • Upgrade the memory in your iMac to enjoy greater performance for more intensive computing tasks and allow professional applications like Aperture and Final Cut Pro to run at peak performance.

Important note: Every 21.5-inch iMac comes with 8GB of memory built into the computer. If you think you may need 16GB of memory in the future, it is important to upgrade at the time of purchase, because memory cannot be upgraded later in this model.
