The new Crosshair IV Extreme from ASUS’ Republic of Gamers brand delivers compatibility with some of the fastest processors available through the AMD890FX chipset. It further ships with CrossLinx 3 technology, which enables multi-GPU usability with graphics cards from different vendors and generations. The new motherboard also comes with a slew of user-friendly overclocking features, including ROG Connect, RC Bluetooth and ROG iDirect.
Graphics Card Flexibility
With CrossLinx 3 technology, Crosshair IV Extreme users gain the ability to mix and match multiple graphics cards from both NVIDIA and ATI, including models of different GPU generations. This technology uses the Lucid HYDRALOGIX engine, which bridges various graphics cards to enable their simultaneous usage. By removing compatibility hurdles, CrossLinx 3 makes it possible to experiment with different configurations of graphics cards for maximum performance.
On Crosshair IV Extreme, a unique layout design features a total of five PCI Express expansion slots. Two provide dedicated native graphics card support for either a single GPU or two in CrossFire configuration. The additional three feature Lucid HYDRALOGIX and CrossLinx 3 technologies, which enable a mixture of graphics cards from different vendors and generations, with a total of four detectable and working at once. Users keen on tuning their system gain greater freedom to do so with the unprecedented five PCI Express slots, and the technology maintains optimized performance whether in single or multiple-GPU arrangements.
Revolutionary User Control
Crosshair IV Extreme continues ROG’s established tradition of extreme performance, bringing much needed hardcore overclocking capabilities to the AMD side of the market. It ships with a full range of performance features, starting with ROG Connect, which enables pure hardware-level tweaking through USB from a remote notebook PC.
RC Bluetooth accesses a host of board, memory and CPU overclocking parameters from any Bluetooth-enabled device, while ROG iDirect introduces PC tuning from iPhone. This adds convenience and style to overclocking, a practice that used to be exclusive and cumbersome to get into.
These features simplify overclocking without compromising results, so that any user, novice to hardcore, can tap the full potential of Crosshair IV Extreme and related hardware with minimum difficulty and for maximum gain. All have been designed with direct feedback from the PC performance community taken into consideration.
