Pro Overclocking Feature
the new X-Socket
feature is a swappable bracket that lets you keep on using a LGA1366 based heatsink/cooler you might have from a previous system. For those that have already dropped a pretty penny on a high end cooling solution, you can definitely get some extra mileage from your older heatsink with the X-Socket. It is available for Rampage IV Extreme and Formula motherboards.
