One click takes care of all that complex tuning. ASUS 5-Way Optimization makes your PC smart. Asus Prime X299 dynamically optimizes essential aspects of the system, providing overclocking and cooling profiles that are tailored for your rig.
An automated tuning utility that optimizes overclocking and cooling profiles for your unique system configuration.
Fans stay whisper-quiet for everyday computing, and deliver optimal airflow when the system is crunching through CPU or GPU-intensive tasks.
All-new stress test that allows users to optimize and overclock for CPU or memory-centric workloads.
Each header can be set to monitor and react to three user-configurable thermal sensors, for workload based cooling. All easily managed by Fan Xpert 4 or UEFI.
The smoothest, slickest mouse-controlled graphical BIOS has been improved to make it even more appealing. Whether you're a PC novice or a seasoned overclocker, the EZ and Advanced Modes help you find your way, quickly and easily.
With optimized trace paths for time-aligned signaling and minimal crosstalk, Third-generation ASUS T-Topology offers enhanced memory stability and compatibility, allowing support for memory speeds of DDR4-4133 MHz and beyond.
Unleash the Asus Prime X299 Virtual RAID on CPU (VROC) feature with the addition of an ASUS Hyper M.2 X16 Card*, which allows you to attach up to four PCIe® 3.0 x16 M.2 drives for a total bandwidth of up to 128Gbps. With VROC, you can utilize CPU PCIe lanes to configure a bootable RAID array, eliminating traditional DMI bottlenecks, so that storage transfers aren't held back by other traffic.
Intel Optane is a revolutionary non-volatile memory technology supported by Prime X299-A. Intel Optane memory modules accelerate attached storage to reduce boot and load times, so everything feels faster and more responsive.
Prime X299-A's front panel USB 3.1 connector is ready for next-gen PC cases and devices.
With backward-compatible USB 3.1 Gen 2 Type-A™ and reversible USB 3.1 Gen 2 Type-C ports, you'll experience ultimate connection flexibility and blazing data-transfer speeds of up to 10Gbps.
Experience blistering ThunderboltTM 3 speeds and any-way-up connectivityPrime X299-A offers support for ThunderboltEX 3 card, an Intel-certified Thunderbolt 3 add-on card enables breathtaking bi-directional speeds of up to 40Gbps through a single cable up to 4X faster than other PC data-transfer protocols. Beyond sheer bandwidth, Thunderbolt 3 supports daisy-chaining up to six devices; utilizes a Type-C reversible connector for compatibility with the latest USB 3.1 Gen 2 Type-C devices; and supports the USB Power Delivery specification for fast, high-power charging of up to 36W.
More throughput, less CPU usage and great gaming experiencesPrime X299-A features the latest Intel Ethernet. Intel's LAN has the advantage of reducing CPU overhead and offering exceptionally high TCP and UDP throughput for faster, smoother data transfer.
With support for both NVIDIA SLI and AMD CrossFireX 2/3-WAY configurations, Prime X299-A motherboard enables multi-GPU setups so you can harness the full power of the latest graphics technologies to drive games at 4K and beyond.
SafeSlot is the PCIe slot reinvented by ASUS and engineered to provide superior retention and shearing resistance. Manufactured in a single step using a new insert-molding process, SafeSlot integrates the slot with fortifying metal for an inherently stronger slot, which is then firmly anchored to the PCB through additional solder points.
A well-tuned enthusiast system deserves a matching aesthetic. ASUS Aura offers full RGB lighting control with a variety of functional presets for the built-in RGB LEDs as well as strips connected to the onboard RGB headers. And it can all be synced with an ever-growing portfolio of Aura-capable ASUS hardware.
Dedicated 3D mounts on the motherboard makes fitting 3D-printed parts easy. Using the same screws as M.2 drives and standard motherboard mounting holes, you can easily add nameplates and cable covers.
