UEFI BIOS And Overclocking

The ASUS Sabertooth X99 TUF features a BIOS environment very reminiscent of the UEFI BIOS found on ASUS Z97 motherboards. It offers an easy and intuitive design for navigation.

Plus it reprises the EZ Tune BIOS environment that allows for single-click OC options. We were unable to hit our desired 4.5OC using the EZ Tune method, however, we were able to run our CPU at those speeds my manually tuning the board.

The UEFI BIOS offers a wealth of tuning options for more experienced overclockers. Users can tweak multipliers, clock settings, enable or disable on-board peripherals, and everything else you've come to expect from ASUS' high-end motherboards.

Under the AI Tweaker BIOS setting, is where you'll find more hands-on tuning options. It under this menu we were able to achieve our 4.5 OC with a few simple tweaks to the BLCK frequency and core ratio (100.10 x 45 to be exact). We made sure to sync all cores and bumped the memory up from 2133MHz to 2667MHz as well.

ASUS also offers what it calls Thermal Radar 2m on this board, both via the BIOS and a Windows utility. Thermal Radar is a robust set of tools for creating and monitoring fan profiles. We mentioned the 11 fan connectors already, they can be used along with the bevy of sensors and the bundled Thermistor cable to monitor video cards temps and other vitals in real time--and optimize in a single click.

ASUS has a very accessible tool in the current iteration the their UEFI BIOS. Again, not much at all has changed from their Z97 and the X99-Deluxe, but that's a good thing. EZ Tune is simple solution to easily overclock CPU and memory. But that's not going to cut it for the demanding overclocker who enjoys manual tweaking. The Sabertooth X99 TUF definitely has you covered on both fronts though.
