11 Power Phase Design Designed with an 11-Power-Phase Design, this motherboard features sturdy components and completely smooth power delivery to the CPU. Plus, it offers unmatched overclocking capabilities and enhanced performance with the lowest temperature for advanced gamers as well. Dr. MOS Dr. MOS is optimized for monitoring current and temperature of each phase, thus delivering smoother and neater power to the CPU with enhanced performance and OC capability. IR® Digital PWM The onboard IR® Digital PWM controller delivers the most precise and stable power so that users may achieve optimal performance. Separated CPU Power Connector Design Unlike traditional dual CPU power connectors which are located closely together at the same side, ASRock separates them to either side of motherboard in order to create wider trace for CPU VRM. This design brings better power delivery efficiency and lower temperature, thus improving system stability and increasing overclocking potential. ECC Memory Support ECC (Error-correcting code) is a method of detecting and correcting single-bit memory errors. It''s mission-critical to minimize errors in data especially for the server business and data centers. This motherboard is capable of supporting DDR4 ECC un-buffered memory modules that delivers server-grade performance and rock-solid durability for high-end computing systems, such as scientific or financial computers. Supports 4-Way SLI / CrossFireX VGA Cards This flagship motherboard is able to support 4-Way SLI or 4-Way CrossFireX effortlessly. Not only support gaming graphics card, it is also fully compatible with NVIDIA® Quadro® & AMD FireProTM professional desktop workstation graphics solutions. Dual Band 802.11ac WiFi No one has time for weak WiFi signals and sluggish internet! That''s why this motherboard comes with a 802.11ac WiFi (2.4G / 5G WiFi) module which supports wireless networks and Bluetooth v4.2. Dual Intel® LAN Users are able to connect two LAN cables to this motherboard''s rear I/O. Dual LAN with Teaming function enabled on this motherboard allows two single connections to act as one single connection for twice the transmission bandwidth, making data transmission more effective. Triple Ultra M.2 Triple of the world''s fastest PCIe Gen3 x4 Ultra M.2 slots that deliver up to 32Gb/s transfer speed, it also supports SATA3 6Gb/s M.2 modules. RGB LED Build your own colorful lighting system! RGB LED and header allows users to connect LED strip and create their unique PC style easily. The ASRock RGB LED utility can be downloadeddirectly or from an all-in-one utility ASRock Live Update & APP Shop! 8-Layer PCB / Better DDR4 Performance The 8 Layer PCB comes with 4 sets of 2 ounce copper inner layers, providing stable signal traces and power shapes and delivering lower temperature and higher energy efficiency for overclocking! Thus, it''s able to support the latest DDR4 memory modules with most extreme memory performance! XXL Aluminum Alloy Heatsink Extra large aluminum alloy heat sinks that effectively take away heat from the MOSFET and chipset so that your whole system may perform more stable. Premium 60A Power Choke Compared to traditional chokes, ASRock''s premium 60A power chokes effectively make the saturation current up to three times better, thus providing enhanced and improved Vcore voltage to the motherboard.
