ASUS 990FX overview

  • 1Description

The TUF Sabertooth 990FX R3.0 AM3+ ATX Motherboard from ASUS is designed to fit in standard sized ATX cases. The 12.0 x 9.6" TUF Sabertooth 990FX supports AMD FX, Phenom II, Athlon II, and Sempron 100 series processors, the AMD AM3+ socket, and the AMD 990FX/SB950 chipset. This motherboard is compatible with Windows 10, 8.1, and 7 operating systems and also supports USB 3.1 Type-A and Type-C, each of which can achieve data transfer rates of up to 10 Gb/s.

The ATX form factor of the TUF Sabertooth 990FX can support 32GB of RAM and comes with four 240-pin dual-channel DIMM slots that can each hold 8GB of DDR3 1866, 1600, 1333, or 1066 MHz MHz ECC/non-ECC unbuffered memory. It also has a total of 5 x SATA III 6 Gb/s ports and 1 x M.2 Socket 3 connector that supports SATA & PCIe SSDs, 1 x USB 3.1/3.0/2.0 Type-C port, 3 x USB 3.1/3.0/2.0 Type-A ports, 8 x USB 3.0/2.0 Type-A ports, 8 x USB 2.0/1.1 Type-A ports, 5 x audio jacks, 1 x S/PDIF out, and 1 x Gigabit LAN port. To provide data redundancy, RAID 0, 1, 5, and 10 modes are supported. For those looking to expand their system using PCIe, there are 3 x PCIe 2.0 x16 slots (dual x16 or x16/x8/x8), 1 x PCIe 2.0 x16 slot (x4 mode), and 2 x PCIe 2.0 x1 slots. While this motherboard does not have any video out ports, it does have multi-GPU support for NVIDIA 3-Way SLI technology and AMD 3-Way CrossFireX technology.

The TUF Sabertooth 990FX R3.0 is designed to complement your battle-ready rig. To this end, it is tested for 24/7 durability and is built with armored ports and room for an additional 40mm fan to help optimize airflow and boost heat dissipation. System cooling can be further optimized using Thermal Radar 2, which is customized fan tuning to help tweak system cooling. ASUS' ESD guard helps to protect against static electricity, while DIGI+ Power control offers precise memory tuning in addition to accurate CPU voltage control, helping to reduce wasteful voltage discrepancies and provide a more stable CPU and memory setup.

Included with the TUF Sabertooth 990FX R3.0 is an ASUS Q-Shield, 4 x SATA III 6 Gb/s cables, an SLI bridge, and a Q-connector (2-in-1). Protection is provided by a limited 5- year warranty.

General Features

Tough Inside and Out

Innovative and Creative
The Sabertooth 990FX R3.0 drives ASUS TUF's direct-etching concept forward by using a military-inspired digital pattern directly onto the board in gun-metal gray.
Brighten Up Your Build
A well-tuned enthusiast system deserves a matching aesthetic. ASUS Aura offers full RGB control with a variety of presets for its onboard LED illumination, all of which can be synced with an ever-growing portfolio of Aura-capable ASUS hardware.
Patent-Pending SafeSlot
SafeSlot is the PCIe slot reinvented by ASUS and engineered to provide improved retention and shearing resistance which protect your graphics card. Manufactured in a single step using an injection-molding process that integrates the slot with the fortifying metal for an inherently stronger slot, it is then firmly anchored to the PCB through additional solder points.
Q-LED Indicators
With a design inspired by an armored cockpit, see the power and act on the alerts, with a clear indication of five vital boot actions.


Armored Ports Add-On Cooling
The Sabertooth 990FX R3.0's connectivity ports are protected by strong armor. Additionally, if you fit another 40mm fan in the chassis, the port armor boosts airflow for improved cooling - with temperature reductions of up to 52°F / 11°C!
Thermal Radar 2
Thermal Radar 2 lets you control fans on ASUS graphics cards, as well your case fans. Multiple onboard sensors also let you monitor temperatures onboard and other key components in real time, so you can adjust manually or optimize automatically with one click.

24/7 Durability

Limited 5-Year Warranty
The service will follow the local standard and service policy.
TUF LanGuard - Intel Gigabit LAN
The Sabertooth 990FX R3.0 is engineered with Intel Gigabit Ethernet for fast networking at up to 1 Gb/s, and protected by TUF LANGuard: this military-grade technology integrates advanced signal-coupling technology and surface-mounted capacitors to improve throughput - protecting the Sabertooth 990FX R3.0 from lightning strikes and static electricity.
TUF Components
TUF Alloy Chokes:
Up to 13.6% cooler for extra durability

TUF Caps:
Up to 5,000 hours

Military-grade certified MOSFETs with lower RDS(on). Low RDS means more power efficiency and produce slightly less heat as a by-product of the MOSFET
TUF ESD Guards 2
Electrostatic discharge (ESD) can happen suddenly, and its damaging effects are easily underestimated. TUF ESD Guards 2 technology is tested to standards that are up to 2X higher than industry standards and pin-level on specific rear IO connectors testing is up to 30% higher than the previous TUF standard, helping to ensure electrostatic discharges are properly grounded from all onboard connectivity - and that means greater component longevity for audio connectors, LAN ports, and USB connectors.

Data Transfers

10 Gb/s USB 3.1
With three USB 3.1 Type-A ports for complete backward-compatibility with existing USB devices and one reversible USB 3.1 Type-C for any-way-up convenience, you're all ready for speeds of up to 10 Gb/s, which is twice as fast USB 3.0. And with ASUS' USB 3.1 Boost technology, USB 3.1 is automatically accelerated even further.
Up to 20 Gb/s M.2
Using a Gen2 x2 connection, M.2 storage can achieve speeds up to 10 Gb/s. Using a Gen 2 x4 connection, it can reach up to 20 Gb/s
Turbo LAN
Turbo LAN with cFosSpeed traffic-shaping technology adds even more lag-reducing support and an intuitive user interface. It allows you to lower lag with no expert knowledge - by up to 1.45x! If you're a tweaker, use the Advanced Mode for hardcore controls.
TUF Audio Design
TUF Audio Design makes short work of optimizing audio settings for the way you want to listen, chat, watch movies, or relax to your favorite music. Onboard physical shielding, a professionally engineered design, and premium components result in sound output that has high clarity and fidelity.

The Power of AMD

AMD 990FX Chipset
AMD's 990FX Chipset is designed to support up to 5.2 GT/s HyperTransport 3.0 (HT 3.0) interface speed and dual PCI Express 2.0 x16 graphics. It is optimized with AMD AM3+ and multi-core CPUs to provide excellent system performance and overclocking capabilities.
AMD AM3+ FX/Phenom II /Athlon II /Sempron 100 Series Processors (up to 8-Core)
This motherboard supports AMD AM3+/AM3 multi-core processors with L3 cache and delivers better overclocking capabilities with less power consumption. It features dual-channel DDR3 memory support and accelerates data transfer rate up to 5200 MT/s via HyperTransport 3.0 based system bus. This motherboard also supports AMD CPUs in the 32nm manufacturing process.

    ASUS 990FX reviews

    TUF Sabertooth 990FX R3.0 AM3+ ATX Motherboard is rated 5.0 out of 5 by 3.
    Rated 5 out of 5 by from I wish this board existed 3 years ago! I built an AMD FX PC about 3 years ago for audio recording and editing and it ran great. About 18 months ago I expectantly had a need to do video editing and rendering with my PC. I figured I have a decent CPU and GPU so I would be ok. To make a long story short, I was frequently having freezes and crashes, especially when the weather got warmer. I did have multiple heat issues going on and had to upgrade to a water cooler for my CPU which was a big help, but the crashing still continued. After much trouble shooting, I figured out that my old mother board north bridge was over heating and I damaged it over the last year. This Asus mother board runs way cooler than my old MSI 970-G46 and I haven't had a single crash even when rendering video when my room was hot around 85 degrees Fahrenheit. All the other features of this mother board are great, truly an upgrade from my old board. The only complaint I have which is very minor is that it only has 5 SATA ports, my old board had 6 and I'm using all of them. No biggie I just need to get a PCIe SATA expansion card.
