The SABERTOOTH TUF X99 USB 3.1 Motherboard from ASUS is designed to fit in standard sized ATX cases. The 12.0 x 9.6" SABERTOOTH TUF X99 supports Intel Core i7 processors, the LGA2011-v3 socket, and the Intel X99 chipset. It has been designed to deliver power and speed to Internet browsing, extreme gaming, CAD software, and more. It also features a strengthened backplate and a flexible cooling system for increased stability. This motherboard is compatible with 32 and 64-bit editions of Windows 8.1, 8, and 7 operating systems. It also supports USB 3.1 which can achieve data transfer rates of up to 10 Gb/s.
The ATX form factor of the SABERTOOTH TUF X99 can support 64GB of RAM and comes with 8 x DIMM slots that can each hold 8GB of 288-pin DDR4 2400/2133 MHz non-ECC, unbuffered memory. The SABERTOOTH TUF X99 also has a total of 8 x SATA III 6 Gb/s ports, 1 x SATA Express connector, 1 x M.2 connector that only supports PCIe SSDs, 2 x USB 3.1/3.0/2.0 ports, 8 x USB 3.0 ports, 8 x USB 2.0/1.1 ports, 5 x audio jacks, 1 x S/PDIF out, and 2 x Gigabit LAN ports. To provide data redundancy, RAID 0, 1, 5, and 10 modes are supported and PCIe expansion is dependent on whether a 40 or 28-lane CPU is installed. When a 40-lane CPU is installed, users will have access to three PCIe 3.0/2.0 x16 (x16, x16/x16, x16/x16/x8) lanes. When a 28-lane CPU is installed, users will have access to three PCIe 3.0/2.0 x16 (x16, x16/x8, x16/x8/x4), one PCIe 2.0 x4 (x2 mode), and one PCIe 2.0 x1 lanes. While this motherboard does not have any video out ports, it does have multi-GPU support for NVIDIA Quad-GPU SLI technology, NVIDIA 3-Way SLI technology, AMD Quad-GPU CrossFireX technology, and AMD 3-Way CrossFireX technology.
The SABERTOOTH TUF X99 is designed to be a complete solution provider. To this end, it undergoes server-stability tests of over 7,000 hours and compatibility checks with over 1,000 devices. To help it achieve these standards, this motherboard is built with Thermal Armor and a flow valve to help optimize airflow and boost heat dissipation, as well as Thermal Radar 2, which is customized fan tuning to help tweak system cooling. TUF ICe is a microchip that helps deliver precise temperature monitoring and fan controls, and the TUF Fortifier helps improve rigidity and cooling behind the board, to help ensure that the motherboard won't collapse under heavy components. The TUF Fortifier also includes a thermal pad to help direct heat away from the VRM and other components.
