In fact, we’re so confident of the reliability and durability of our products that each and every TUF motherboard.  ASUS Pro Clock II TechnologyDEDICATED DESIGN FOR OVERCLOCKINGTUF 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-TopologyMAKE YOUR MEMORY GO FASTERASUS 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 3INSTANT FAN TUNING, COMPLETE SYSTEM COOLINGOur 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 reliabilityYou 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!  SafeSlotPROTECT YOUR GRAPHICS CARD INVESTMENTSafeSlot 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 22X-STRONGER ESD PROTECTIONESD 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 connectorWith backward-compatible USB 3.1 Gen 2 Type-A, you’ll experience ultimate connection flexibility and blazing data-transfer speeds of up to 10Gbps.  Speed up with onboard M.2 up to 32GbpsWith x4 PCI Express 3.0/2.0 bandwidth, TUF X299 Mark 2’s dual M.2 supports up to 32Gbps data-transfer speeds. It’s the perfect choice for an operating system or application drive, providing fast access to data.  Intel VROC supportUnleash the TUF X299 Mark 2 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 readyIntel Optane is a revolutionary non-volatile memory technology supported by TUF X299 Mark 2. Intel Optane memory modules accelerate attached storage to reduce boot and load times, so everything feels faster and more responsive.  Intel Gigabit LANMORE THROUGHPUT, LESS CPU USAGE AND GREAT GAMING EXPERIENCESDon’t let slow networking disrupt your workflow! With Intel Gigabit Ethernet connectors, TUF X299 Mark 2 keeps your data moving swiftly and efficiently. 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 LANNETWORK-OPTIMIZATION SOFTWARE FOR CUSTOMIZABLE PACKET PRIORITIZATIONTurbo 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 LANGuardMILITARY-GRADE LAN PROTECTIONTUF 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 SHIELDINGSeparates analog/digital signal domains, significantly reducing multi-lateral interference.UNIQUE POP-REDUCING CIRCUITReduces start-up popping noise to all audio outputs.INTEGRATED AMPLIFIERCapable of driving high-impedance headphones, without rolling-off high or low frequencies.DEDICATED CHANNEL LAYOUTSSeparate layers for left and right channels to guard the quality of the sensitive audio signals.PREMIUM JAPANESE-MADE AUDIO CAPACITORSPremium parts provide an immersive sound signature, with exceptional fidelity.  Aura SyncA 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.  Intel CPU and Chipset features  INTEL X299 CHIPSETThe Intel X299 chipset supports LGA 2066-socket Intel Core X-series processors. It provides improved performance by utilizing serial point-to-point links, allowing increased bandwidth and stability. Additionally, X299 provides a maximum 10 USB 3.1 Gen 1 ports, 8 SATA 6Gbps ports and 32Gbps M.2 support for faster data retrieval.   INTEL CORE X-SERIES PROCESSORS FOR LGA 2066 SOCKETIntel Core X-series processors (6-core and above): 4-channel (8-DIMM), 44/28 PCI Express 3.0/2.0 lanes.
