The ROG Rampage IV Extreme comes with OC Key, a new attachment derived from ROG Connect technology. It plugs in to the DVI port of any graphics card, and integrates with the system to allow instant on-screen performance info and overclocking options. The biggest draw is probably immediate access to voltage tuning, but there are a bunch of parameters that can be applied. And you don't even have to boot the OS, as long as the motherboard, CPU, and graphics card are powered, OC Key works and makes adjustments instantly. The OSD is quite detailed, plus it does work from within the OS just as easily since the attachment talks directly to the BIOS versions of both the graphics card and motherboard on a hardware level. This means overclocking using OC Key doesn't require any system resources, so it's perfect for benchmarking fiends who want to suss out every last drop of power. OC Key doesn't affect benchmarking results, unlike software tuning.
Alongside all the other features that come with Rampage IV Extreme (not to mention Battlefield 3 if you get the limited edition bundle), OC Key, is a huge attraction for serious overclockers. Plus, it's a compact attachment that works with no hassles. Take a look at the photos for a better sense of what it entails.
