Following in the legacy forged by the Rampage 111 Black Edition, the R4BE - as it is known by ROG fans - is the perfect marriage of gaming and overlocking. Sacrificing nothing to appease both crowds, the Rampage IV Black Edition delivers the ultimate X79 experience. BlackWing Choke, 90% efficient NexFET MOSFETs and 10K Black Metallic Capacitors lay the groundwork for Extreme Engine Digi+ to provide the highest, most stable overclocking. The bundled OC Panel lets you make the most of these superior components, with two different modes. In Normal Mode, OC Panel installs into an available 5 ¼in. drive bay and displays CPU temperature, ratios, BCLK and fan RPM. Switching to Extreme Mode and utilizing the OC Panel as a handheld device unlocks its enthusiast overclocking functionality. Connectors for Subzero Sense, VGA SMB and VGA hotwire are available directly on the OC Panel, as well as remote power and reset buttons.
