Make your memory go faster
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.
OC design- ASUS PRO Clock II technology
A dedicated base-clock generator that extends CPU and memory overclocking margins. This custom solution works in tandem with the TPU to enhance voltage and base-clock overclocking control, providing the flexibility to extract every ounce of performance from Intel® Core™ X-series processors.
Connect everything, ultra-fast
With x4 PCI Express 3.0/2.0 bandwidth, M.2 supports up to 32Gbps data-transfer speeds. It is the perfect choice for an operating system or application drive, providing fast access to data.
Prime X299-A has an ultra-efficient heatsink to reduce M.2 SSD temperatures by up to 20°C — and that means optimal storage performance and improved SSD longevity.
Unleash the Prime X299-A 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 memory
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.
USB 3.1 Gen 2 front-panel connector
Prime X299-A's front panel USB 3.1 connector is ready for next-gen PC cases and devices.
USB 3.1 Gen 2 Type-A & Type-C
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.
ThunderboltEX 3 Card
Prime 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.
Prime 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.
Step up to multi-GPU graphics
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.
Upgrade to unrivaled audio
Prime X299-A utilizes a unique audio codec designed in close collaboration with Realtek — the Realtek S1220A. It also features an unprecedented 120dB signal-to-noise ratio for the stereo line-out and a 113dB SNR for the line-in, providing pristine audio quality. Additionally, a new impedance-sensing circuit automatically adjusts gain to ensure the optimal volume range for your headphones.
Immersive 3D surround-sound technology provides incredible audio experiences.
Crystal Sound 3
Power pre-regulator: Reduces power-input noise to ensure consistent performance.
Audio shielding: Separates analog/digital signal domains, significantly reducing multi-lateral interference.
Separate layer for left and right tracks: Ensures minimal crosstalk between audio paths.
Integrated amplifier: Capable of driving high-impedance headphones, without rolling-off high or low frequencies.
De-pop circuit: Reduces start-up popping noise to all audio outputs.
Premium Japanese-made audio capacitors: Premium parts provide an immersive sound signature, with exceptional fidelity.
Make it your own
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.
Exclusive 3D mount for easy installation
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.
