M5A99X EVO supports AMD AM3+/AM3 multi-core processors with unique L3 cache and delivers better overclocking capabilities with less power consumption. It features dual-channel DDR3 1866 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 32nm manufacturing process. AMD 990X Chipset is designed to support up to 5.2GT/s HyperTransport 3.0 (HT 3.0) interface speed and dual PCI Express 2.0 x16 graphics. It is optimized with AMD latest AM3+ and multi-core CPUs to provide excellent system performance and overclocking capabilities. M5A99X EVO brings you the multi-GPU choice of either SLI or CrossFireX. The motherboard features the most powerful AMD 990X platform to optimize PCIe allocation in multiple GPU configurations. Expect a brand-new gaming style you've never experienced before.


The world's first Dual Intelligent Processors from ASUS pioneered the use of two onboard chips - TPU (TurboV Processing Unit) and EPU (Energy Processing Unit). Its new generation of Dual Intelligent Processors 2 with DIGI+ VRM launches power delivery into a digital standard with a programmable microprocessor that perfectly serves power (SVID) requests from the CPU, eliminating digital-to-analog conversion lag. It's the most precise power delivery available providing the best in class power efficiency, greater performance, and rock solid stability. With ASUS DIGI+ VRM, users can easily adjust power phase performance and system voltages via diverse settings in the intuitive UEFI interface.
