ASUS Sabertooth X99 TUF Review: USB 3.1 Tested
UEFI BIOS And Overclocking
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 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.
