iMac 27-inch 3.2GHz Intel Core i3 (MC510LL/A)

With its 27-inch screen, your old Apple iMac MC510LL/A desktop with its 3.2GHz Intel Core i3 processor is still a great tool for working with graphics or watching HD video. But if your iMac could use a little more memory for better performance, choose one of Memory America's upgrade options. With four slots, your iMac can accommodate up to 32GB of RAM, a big jump from the standard 4GB of RAM your iMac came with. These 204-pin small outline dual inline memory modules (SODIMM) listed below are smaller and thinner than regular DIMMs and fit into the tight spaces of laptop computers and your sleek iMac.
