Right now is a slightly confusing time to buy RAM. Those upgrading from a dusty old system with DDR2 support to a current platform such as Intel's Z68 or AMD's 990FX, will need to invest in some DDR3 memory to play nicely with your new chipset. If you're on a triple channel chipset such as Intel's X58, you'll need three DDR3 modules instead of two. Why? Because there are three slots and you need to fill them. Just keep looking at the slots, manufacturers keep saying.
