This new capability also allows users to get set up sizeable RAM-disks and speed-up access times of frequently accessed programs, minimizing the impact of storage transfer delays whilst maximizing user experience.
• 4-Way GPU Support
  Whether its NVIDIA SLITM or AMD CrossfireXTM Rampage IV Extreme supports up to four graphics cards for uncompromised graphics and performance.
• USB 3.0 Boost with UASP Support
  UASP support provides up to 170% faster USB 3.0 transfer rate by allowing multiple data requests instead of single command mode of BOT. USB 3.0 Boost in Turbo Mode can significantly improves data transfer rates of any USB 2.0 or 3.0 storage device for enhance performance and time saving.
• High-speed Networking with Intel Gigabit LAN
  Intel Gigabit LAN provides the best throughput performance with reduced impact on CPU usage. It provides superior compatibility and interoperability with multiple networking devices to make networking your PC a breeze.
• X-Socket
  With an ingenious 3-piece design the exclusively designed ROG X-Socket provides compatibility with existing LGA 1366 socket coolers as well as LGA 2011 socket coolers. In addition it also provides mounting for your LN2 pot for extreme overclocking.
