MSI mainboard maintains the commitment to product stability & reliability! In addition to the use of Hi-c CAP, SFC, & Solid CAP, MSI incorporates Dr MOS II, the Dr MOS that provides an integrated double thermal protection to maximize the lifespan of components. X79A-GD45 (8D) features AMD Cross Fire technology, which is the ultimate multi-GPU performance gaming platform. Enabling game-dominating power, AMD Cross Fire technology enables two or more discrete graphics processors to work together to improve graphics performance. AMD Cross Fire technology means that you can expand your system's graphics capabilities. It allows you the ability to scale your system's graphics horsepower as you need it, supporting up to four AMD Radeon HD graphics cards, making it the most scalable gaming platform ever. With an AMD Cross Fire gaming technology, the traditional graphics limitation exists no more, allowing you to enjoy higher performance as well as visual experience. Active Phase Switching, APS, technology is an intelligent design that helps to save energy on MSI's mainboard. The underlying idea is to switch off the power supply as soon as no electricity is needed, & when the system needs more resources again, APS will automatically adjust electricity supply accordingly. APS will automatically detect your processor's loading at any given time & save energy accordingly. This is only possible by means of a very advanced power controlling technology. Other than software-based solutions, APS technology stands out from MSI's own research. The specially developed IC chip can operate automatically depending on the demands of the power supply, which is to reduce the total power usage.
