Leading AM3+ Performance.

Designed from the ground up to take full advantage of the new
8-core "Bulldozer" AM3+ processors, the ASUS Sabertooth 990FX motherboard is also backward compatible with current AM3
processors. The story on platform flexibility doesn't end here.
The new motherboards will be first on the AMD chipset based platform to support both multi-GPU technologies: AMD Quad-GPU CrossFireX™ and NVIDIA® Quad SLI™ Technology.

Best-in-Class Cooling Technology

The new Sabertooth 990FX features an innovative passive heat sink solution that features exclusive CeraM!X technology and a 10-sensor system that actively monitors critical thermal points on the board to provide the best thermal management available today. Premium ceramic-coating
technology on critical components such as the MOSFET and the chipset heat sinks lead to an overall improvement in system stability. The TUF CeraM!X technology accomplishes this by enlarging the surface area with
its micro-porous surface – 50% more – to effectively dissipate heat.


The ceramic coating used in this technology has an excellent heat conduction property even when air flow is poor. In addition, CeraM!X is
heat tolerant and oxidization resistant, yielding to additional stability of the system.


The TUF Thermal Radar is the active thermal monitoring system featuring 10 hardware sensors embedded on-board for real-time thermal detection and reporting. Users can choose to take advantage of the manual controls or use the preset profiles to adjust fan speed and voltages automatically.

Mouse-controlled Graphical UEFI BIOS

Take control of your system with UEFI (Unified Extensible Firmware
Interface), going beyond tradition keyboard-only BIOS controls to enable more flexible and convenient mouse input. Users can easily click, drag, scroll and navigate the new UEFI BIOS with the same smoothness as their operating system. With native support for hard drives larger than 2.2TB in 64-bit, and an intuitive EZ Mode, ASUS UEFI BIOS is the new standard in motherboard setup and control.

  leading technology editors

• Exclusive EZ Mode allows drag and drop boot prioritizing

Dual Intelligent Processors 2
with DIGI+ VRM

Go beyond analog limits with digital voltage regulation.
Now available on the AMD platform, the new ASUS Sabertooth 990FX motherboard feature Dual Intelligent Processors 2 with DIGI+ VRM offering precise power control for optimized performance and a reduction in electronic interference, lowering noise leakage into sensitive system components.


• The new digital power design (DIGI+ VRM) perfectly serves
  AM3+ CPU power demand, offering precise power
  management that eliminates performance bottlenecks.

• New DRAM Power Control option for CPU/NB maximizes
  memory overclocking potential by up to 30%

Advanced Connectivity

True SuperSpeed USB 3.0 and SATA 6 Gb/s offer the next-generation of high bandwidth data transfer. Enjoy up to 10x faster USB 3.0 transfer speed over USB 2.0, and 2x faster SATA 6 Gb/s transfer speed over SATA 3 Gb/s.

TUF Components Meet Extended Warranty

The new Sabertooth 990FX motherboard features military-class components to complete the TUF promise. Each motherboard features TUF alloy chokes made using high-grade materials with
anti-oxidization properties for extra durability, solid capacitors and TUF MOSFETs. Compared to standard ferrite chokes, high-permeability alloy chokes maintain higher inductance within the same package size to deliver a more stable supply of power without sacrificing motherboard space. And compared to iron chokes, high permeability alloy core based chokes have higher efficiency, which results in less wasted energy and heat, thus creating a more stable thermal environment for components. The motherboard is then stress-tested following server-grade reliability test procedure, and then backed with an industry-leading 5-year warranty.
