UEFI Features
ASUS bundled the Sabertooth Z170 Mark 1 motherboard with the latest revision of their ASUS UEFI (Unified Extensible Firmware Interface) implementation, a customized version of the AMI baseline UEFI replacement. The UEFI offers full keyboard and mouse support while using the interface pages. ASUS changed the way mouse right-click functions in their UEFI implementation with right-click having no impact on the screen. By default, the user sees the EZ mode screen when entering the UEFI. The Advanced mode screens accessible via the Exit/Advanced Mode button at the upper right corner of the screen or by hitting the F2 function key. Advanced mode screens can be set for the default user interface via the UEFI Boot menu as well.
As we've stated in previous reviews, the ASUS UEFI implementation remains among the best out there. The UEFI is very responsive to both keyboard and mouse input with almost no lag or questionable click-space evident anywhere. The UEFI is designed in an intuitive manner so that both novice and advance BIOS users can quickly find what they are looking for. The EZ Mode screen lays out everything in a highly readable format, while the Advanced Mode tabbed layout displays as you would expect from a traditional BIOS. ASUS also gives you the ability to taken screen captures from within the BIOS by pressing the F12 key with those screen-caps saved in a 1024×768 bitmap format to an attached USB device. From the Tools menu, ASUS houses their collection of of BIOS-related tools and applets, ranging from an UEFI-based updater (EZ Flash3) to their full UEFI profile load and save utility.
UEFI Notable Features
The Sabertooth Z170 Mark 1 UEFI includes enhancements to the features introduced to the interface with their Z97 board line, as well as exposing several new features specific to the Skylake-S processor line. They revised their EZ Mode page with added utility, integrating a customizable My Favorites tab into the Advance mode menu, Shortcut screen, a graphical fan tuning interface, a graphical EZ Tuning Wizard interface, support for display in nine different languages, and a Quick Note interface introducing memo persistence across UEFI sessions.
My Favorites tab, populated
My Favorites & Shortcut setup popup
The My Favorites tab houses user selected settings for access to these from a centralized location. To access, select the My Favorites tab from within the Advanced Mode interface. Note that if a menu or sub-menu is added to this page, all fields on that page will be added. The real strength in this My Favorites tab implementation comes with the ability to mix and match commonly used options in a central location, rather than having to hunt them down through multiple sub-levels of menus.
EZ Mode page
The EZ Mode page presents information organized into sections in an easy-to-read manner for those users who do not want to be bothered with the labyrinth of the Advanced Mode settings.
Q-Fan Tuning page
The Q-Fan Tuning page allows for graphical configuration of fan operation based on predefined threshold levels. The interface is similar in nature to the Windows-based Fan Xpert3 fan configuration interface and is a nice touch in-lei of the text-based configuration approach. The Q-Fan Tuning page is accessed by clicking on the Manual Fan Tuning button within the EZ Mode page.
Easy Tuning Wizard – OC Page
Easy Tuning Wizard – RAID Page
The EZ Tuning Wizard can be accessed by hitting the F11 function key from within the EZ Mode page or from within the Advanced Mode interface. This wizard can be used to setup BIOS configured system performance optimization or drive RAID setup based on user selections made within the wizard interface.
Advanced Mode, Main tab, Quick Note pop-up
The Quick Note window is accessed by clicking the Quick Note field in the top menu bar or hit the F9 function key. From this window, you can enter notes that remain persistent between BIOS sessions. This functionality is only available from the Advanced Mode interface.
Advanced Mode, Tools tab, ASUS EZ Flash 3 pop-up source selection
Advanced Mode, Tools tab, ASUS EZ Flash 3 pop-up USB drive selected
The ASUS EZ Flash 3 utility was updated, allowing for BIOS update via an attached drive or through a network connection. When selecting the network update method, the utility launches a network connection wizard for getting the most up to date BIOS file from the ASUS servers.
Advanced Mode, Monitor tab
ASUS enhanced their Q-Fan control capabilities in their latest UEFI version, allowing for user configurable pauses in between when the BIOS detects a change in threshold temperature and when the BIOS increases the header fan speed. As with previous version of the UEFI, the user is able to set temperature thresholds and fan speeds (based on percentage run speed) for the board's fan headers.
Ai Tweaker tab with Manual mode enabled
For the Z170 Express boards, ASUS opened up the CPU back clock settings with user capable settings up to 650MHz. This is because of the decoupling of the PCI and DMI bus from the base clock with the Intel Skylake processors.
Advanced Mode, Last Modified popup
Advanced Mode, Last Modified popup
The Last Modified page displays to the user a scrollable list of all UEFI changes made since the last save. Listed changes are not committed to BIOS memory until saved by the user. Note that the same list displays when the user chooses any of the save settings from the Exit page.

two additional Weaknesses:
two additional Weaknesses: disgusting sli bridge and two small fans 😉
On my Z77 Sabertooth I had to
On my Z77 Sabertooth I had to force the fans off (horribly whiny things even on lowest speed), and the ONLY way was with the Asus fan software (BIOS settings won’t turn off).
Then I upgraded past Windows 7 and discovered no fan software! Luckily the W7 software worked for W8 and W10.
Now I don’t know how quiet the fans are but if at all noisy they need to rethink things.
Slower, quiet Assist fans would be a LOT better than the only two choices:
1. ON – annoying noise, or
2. OFF – no air flow
*I did set my fans to come on if temp goes above 50degC for the chipset (which for me is rarely), as well as 1 minute after turn off, but MOST people probably wouldn’t figure that out easily.

How can it say it has quad
How can it say it has quad SLi/CFX support with only 3 PCIE Slots
quad support = 2 x dual GPU
quad support = 2 x dual GPU cards…
I expect Star Citizen to
I expect Star Citizen to eventually support four GPU’s via DX12 fairly efficiently.
Maybe a Pascal card similar to 2xGTX980Ti each, with DX12 using four GPU’s for each frame.
(8GB VRAM per GPU would mean 8GB usable for AFR or up to 32GB usable for SFR)
There must be bins filled

The led light on my mouse
The led light on my mouse continues to stay on when I shut down my computer. I tried going in to my BIOS and Ai Tweaker and turn the EPU Power Saving Mode to disabled to Enabled, but that didn’t help. How can I fix this issue?
