Intel LGA-1151 mATX motherboard, DDR4 2666MHz, SATA 6Gbps and USB 3.1 Gen 1 ASUS OptiMem: Careful routing of traces and vias to preserve signal integrity for improved memory stability. Fan Xpert: Flexible controls for ultimate cooling and quietness, plus GPU-temperature sensing for cooler gaming. 5X Protection III: Multiple hardware safeguards for all-round protection. PRIME ASUS Prime 300 Series motherboards provide the solid foundation needed for your first build, plus flexibility to grow with your ambitions. We've melded all the good stuff that's packed into the latest 8th Generation Intel® Core™ processors with essential ASUS design and engineering, so you benefit from industry-leading technologies - including automated system tuning, comprehensive cooling controls, and immersive onboard audio. When you build with an ASUS Prime 300 Series motherboard, you build smart, easy and affordably. Tune it your way Improved DDR4 stability ASUS OptiMem preserves memory signal integrity by routing traces and vias to the optimal PCB layer, and our T-Topology trace layout ensures time-aligned signaling by balancing trace lengths between memory slots. These enhancements allow the Prime 300 Series to support a wide range of dual and quad-DIMM memory kits, while providing your rig with the stability it needs to deal with any type of workload - whether you're gaming or running intensive applications Cooler by design Prime 300 Series features the most comprehensive cooling controls ever, configurable via ASUS Fan Xpert software or the UEFI BIOS. Multiple temperature sources Each header can be set to monitor and react to up to three thermal sensors. Via Fan Xpert, you can also assign a sensor to monitor the temperature of supported ASUS graphics cards to ensure optimal cooling during GPU- or CPU-intensive workloads. 4-pin PWM/DC fan Each onboard CHA FAN header supports PWM and DC mode. Media-acclaimed UEFI BIOS The UEFI BIOS is an early waypoint on any PC-building journey, and Prime 300 Series has one of the best in the business. Q-Fan Control Can configure the fan's operating speed manually, or use the easy pre-configured fan profiles to select Standard, Silent, Turbo or Full Speed modes, plus automatic switch to full speed if the temperature hits 75°C. EZ mode Intuitive graphical fan control Fine-tune individual fans simply by dragging a curve with the mouse. SATA Information: Display SATA port details that help you easily recognize drives. Fast Clock Adjustment: Use mouse controls to change the time and date. Advanced mode My Favorites Quickly find tuning options and add preferred tools to the list. User Profile Save BIOS settings for migration to new BIOS version or system. SATA Port Renaming: Rename SATA ports for easy identification. Ultrafast connectivity USB 3.1 Gen 1 front-panel connector Future-proof connectivity USB 3.1 Gen 1 is right where you need it, with two super-speed headers for the front panel. Experience data-transfer speeds up to 10X faster than USB 2.0 with instant plug-and-play connectivity, and avoid back-breaking contortions in the hunt for hard-to-reach rear ports.
