Ready for 2nd Gen AMD Ryzen Threadripper

The ASUS Prime X399-A DDR4 Cooling Kit contains an SOC heatsink and a fan bracket, designed to cool vital motherboard power delivery areas to enhance the overclocking potential of 2nd Gen Threadripper Series Processors.

5-Way Optimisation - One-click overclock and cooling, done!

One click takes care of all that complex tuning. ASUS 5-Way Optimisation makes your PC smart. It dynamically optimises essential aspects of the system, providing overclocking and cooling profiles that are tailored for your rig. An automated tuning utility that optimises 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 optimise and overclock for CPU or memory-centric workloads.

Cooler by design

Prime X399-A features the most comprehensive cooling controls ever, configurable via Fan Xpert 4 or the UEFI BIOS. Each header can be set to monitor and react to three thermal sensors, and via Fan Xpert 4 you can even assign a sensor to monitor the temperature of supported ASUS graphics cards, for optimal cooling during GPU or CPU-intensive workloads.

Media-acclaimed UEFI BIOS

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.

Make your memory go faster

Prime X399-A is engineered to support quad-channel memory kits rated up to a staggering DDR4 3600MHz, allowing you to get the best performance from the X399 platform. ASUS have worked with all major DDR4 memory vendors to help ensure compatibility, so you’re assured the best compatibility.

OC Design – ASUS Pro Clock 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 Ryzen Threadripper processors.

Speed up with onboard M.2 up to 32Gbps

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 X399-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.

U.2 connector - Join the NVMe revolution

The revolutionary specification that lets your SSDs scream at top speed. Just attach your chosen drive to with plug-and-play ease to experience data-transfer speeds of up to 32Gbps — and free up a PCIe slot for another expansion card.

Ultimate-speed 10Gbps with USB 3.1 Type-A and Type-C onboard

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.

Multi-GPU support

With support for both NVIDIA SLI and AMD CrossFireX 2/3-WAY configurations, Prime X399-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.

Realtek codec and unique design features for pristine, powerful audio

Prime X399-A utilises 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.
