ASUS Rampage 4 Extreme Review
The OC Key is a strange little bit of kit. It plugs into the graphics card as a throughport, and then into the motherboard.
By pressing the RoG Connect button it brings up a live overclocking display which allows you to tweak in a manner similar to a software based overclocking option, but without the system overheads that it entails.
It's a little awkward, being stuck out the back of your system, for regular use. Perhaps it's also a little bit extravagant as it doesn't do much that we haven't seen from software applications, or indeed the BIOS itself. However it's another string to your overclocking bow, and yet more proof that the Rampage IV Extreme really has got everything in the ASUS armoury.
