I have an old dell vostro 220 and I'm going to do some upgrades on it. The motherboard is a "Dell Inc. 0JJW8N." It has an old core 2 duo which I'm going to upgrade to a core 2 quad and I'm going to add a graphics card to it. It has 4gb of slow memory too. But my question is: Can I upgrade to 8gb of faster RAM with this motherboard??
