Verdict

The ASUS X99-PRO is a high-performance ATX motherboard built on the Intel X99 chipset, supporting LGA 2011-v3 socket processors (Haswell-E and Xeon) and up to 64GB of quad-channel DDR4 memory with overclocked speeds reaching 3300MHz. Key characteristics include the patent-pending OC Socket for enhanced overclocking stability, 5-Way Optimization for one-click system tuning, and robust connectivity featuring onboard 802.11ac Wi-Fi, Bluetooth 4.0, a 32Gb/s M.2 x4 slot, and a bundled Hyper M.2 x4 expansion card. Main pros include its exceptional overclocking potential, high-fidelity Crystal Sound 2 audio, and a comprehensive feature set that rivals more expensive flagship models. However, notable cons include complex PCI-E bandwidth sharing that can disable certain slots or USB ports when M.2 drives are in use, and its relatively high price point compared to entry-level X99 boards.
