look at fry's website they have a rebate on the ram last week. To upgrade just unplug power and remove side cover and you will see the ram stick in the slot. The slot has 2 tabs at both ends. All you have to do is push the tabs down and the ram will be popped out. Then line up the new one and push in slighly and the tabs will snap shut when the ram sits in the slot. Then power on and you should be good to go. Good luck
