TUF X299 Mark 2 includes a dedicated base-clock (BCLK) generator to extend CPU and memory overclocking margins. This custom solution works in tandem with the TPU to enhance voltage and BCLK overclocking control, providing the flexibility to extract every ounce of performance from the Intel Core X-series processors.
ASUS T-Topology
MAKE YOUR MEMORY GO FASTER
ASUS T-Topology allows memory frequencies that are higher than ever — to 4133MHz and beyond. ASUS-exclusive T-Topology circuit design provides superb memory-overclocking capability to unleash the full power of DDR4 by minimizing coupling noise and signal reflection. Refined manufacturing ensures ultra-consistent quality, minimal crosstalk between custom trace paths, and time-aligned signaling for superior stability and compatibility.
Thermal Radar 3
INSTANT FAN TUNING, COMPLETE SYSTEM COOLING
Our Thermal Radar 3 software allows you to control connected chassis fans, water pumps, AIOs, and even the fans of ASUS graphics cards — all to provide ultimate cooling performance for gaming and productivity. Multiple onboard sensors also enable the temperatures of key components to be monitored in real time, so you can assess and optimize cooling efficiency.
24/7 reliability
You demand 24/7 reliability — and we’ve delivered! TUF motherboards undergo the industry’s most punishing tests to ensure they’re ready for long-term duty in any environment. In our tests we overheat them, chill them, bend them, shock them and drop them — so you know that your TUF motherboard is certified for 24/7 reliability!
SafeSlot
PROTECT YOUR GRAPHICS CARD INVESTMENT
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.
TUF ESD Guards 2
2X-STRONGER ESD PROTECTION
ESD Guards 2 protects TUF X299 Mark 2 from damaging electrostatic discharge. ESD Guards 2 is tested to levels that are 2X higher than industry standards. We also perform pin-level* testing at 30%-higher ESD levels than previous TUF standards. Our stringent tests mean greater component longevity for your TUF motherboard!
USB 3.1 Gen 2 connector
With backward-compatible USB 3.1 Gen 2 Type-A, you’ll experience ultimate connection flexibility and blazing data-transfer speeds of up to 10Gbps.

With LAN port, you’ll benefit from increased bandwidth for more speed, automated load balancing for smoother data flows, and instant failover if something should go wrong — so access to your files is always fast, efficient and uninterrupted.
Turbo LAN
NETWORK-OPTIMIZATION SOFTWARE FOR CUSTOMIZABLE PACKET PRIORITIZATION
Turbo LAN with cFosSpeed traffic-shaping technology allows you to configure application priority via an intuitive interface, and reduces network lag – by up to 1.45X!
TUF LANGuard
MILITARY-GRADE LAN PROTECTION
TUF LANGuard, a military-grade innovation that integrates advanced signal-coupling technology and premium surface-mounted capacitors to improve throughput — protecting the motherboard from lightning strikes and static electricity.
AUDIO SHIELDING
Separates analog/digital signal domains, significantly reducing multi-lateral interference.
UNIQUE POP-REDUCING CIRCUIT
Reduces start-up popping noise to all audio outputs.
INTEGRATED AMPLIFIER
Capable of driving high-impedance headphones, without rolling-off high or low frequencies.
DEDICATED CHANNEL LAYOUTS
Separate layers for left and right channels to guard the quality of the sensitive audio signals.
PREMIUM JAPANESE-MADE AUDIO CAPACITORS
Premium parts provide an immersive sound signature, with exceptional fidelity.
Aura Sync
A well-tuned enthusiast system deserves a matching aesthetic. ASUS Aura Sync offers full RGB lighting control with a variety of functional presets for the built-in RGB LEDs. And it can all be synced with an ever-growing portfolio of Aura-capable ASUS hardware.
