Asus Crosshair IV Extreme M-Board No I/O

Asus Crosshair IV Extreme AM3 DDR3 Motherboard. This motherboard supports AMD® Socket AM3 multi-core processors with unique L3 cache and delivers better overclocking capabilities with less power consumption. It features dual-channel DDR3 1333 memory support and accelerates data transfer rate up to 5200MT/s via HyperTransport™ 3.0 based system bus. This motherboard also supports AMD® CPUs in the new 45nm manufacturing process. ATI’s CrossFireX™ boosts image quality along with rendering speed, eliminating the need to scale down screen resolution to get high quality images. CrossFireX™ allows higher anti-aliasing, anisotropic filtering, shading, and texture settings. Adjust your display configurations, experiment with the advanced 3D settings, and check the effects with a real-time 3D-rendered previews within ATI Catalyst™ Control Center.
     


* Please Note: This is an OEM motherboard and it does not come with rear I/O shield also known as back-plate cover. This part is not needed and you can still install the board in standard ATX case.
