    Yes, this type of RAM will work for you. However, since your iMac comes with two slots for RAM. I would recommend not getting one 4GB memory stick, but instead getting 2x2GB memory sticks. The reason being is the processor will divide the work of the RAM between the two memory slots and you'll see better performance than with one 4GB stick installed. The real work of RAM is to help you run multiple software applications at once without lagging. When you divide the work up between two pieces of RAM the processor can partition the work more efficiently.
