The latest GIGABYTE UEFI firmware (F4) on the Z390 Aorus Master appears quite rustic, but has been improved since our last GIGABYTE review.

The firmware on the GIGABYTE Z390 Aorus Master has two primary modes for users to work with. These include the Easy Mode which is the initial splash screen and the classic mode which can be entered by pressing F2. With the Easy Mode, everything is displayed in a block system with eight different four-sided panels. These panels include basic information about different aspects of the mainboard and its installed components such as RAM, storage booting sequence, frequency and voltage monitoring, EZ OC and fan speed information. Users can quickly access functions such as Q-Flash by pressing F8, a handy favorites menu by pressing F11 or access the Smart Fan 5 utility by highlighting the options and physically selecting it with a mouse click or the enter key when highlighted.

Upon pressing the F2 key, users can switch between the Easy and Classic modes. Within the Classic mode is a much more extensive list of options with a list of main menus displayed horizontally across the top. These include M.I.T, System, BIOS, Peripherals, Chipset, Power and Save & Exit. Within each menu is a sub-menu listed vertically and in the case of the M.I.T, this section contains all the tools needed to do overclocking and change frequency and voltage variables. Each of the primary sections such as frequency, memory and voltage setting are all located within their own sub-section, but users can add relevant and commonly changed settings to their favorite menu for easy access.

Despite being a noticeable improvement in terms of GUI from the F4 launch firmware to F7, the layout is still a little basic and doesn’t feature much pizazz from a visual point of view. This isn’t necessarily a negative as each setting and option is clear with white text on a black background; as contrasting as it gets. Present are settings for changing the CPU base clock, integrated graphics ratios CPU clock ratio and a one-click setting to enable X.M.P 2.0 profiles on compatible and supported DDR4 memory.

All the relative power settings such as Turbo Boost Technology ratios, package power limits and C States can be altered within the Advanced CPU Core Settings sub-menu within the Advanced Frequency Settings menu. Users can even enable or disable Intel EIST, Intel Speed Shift and enable or disable CPU cores; users however can only select the number of enabled cores and not select between individual ones.

The GIGABYTE Z390 Aorus Master comes equipped with an integrated fan control utility called Smart Fan 5. With a theme that looks more with the times than some other vendors output, Smart Fan 5 allows users to control each of the seven 4-pin headers individually. There are options to enable an alarm with certain variables including temperature on each of the different sensors and below this is a set of Realtime temperature values on all the different onboard thermal sensors. Users can make their own profiles through a five-point fan curve, or select a predefined one such as normal, quiet, performance and full-speed.

Solid and reliable firmware can make or break the user experience on a motherboard and GIGABYTE’s UEFI firmware does work very well. Much like ASRock does on its premium models, GIGABYTE has separated key overclocking controls into their own subsections which makes it easy to find settings, although there are too many clicks for my liking to get through to the LLC options (four in total). Users can alleviate this by putting their most frequently used options in the favorites panel for quick and easy access. The firmware is very responsive, there are extensive options for power settings and even though in our overclocking section I’ve highlighted some noteworthy points, the GIGABYTE firmware when updated past F5 on the Z390 Aorus Master is good. 


Accompanying the GIGABYTE Z390 Aorus Master is an enthusiastic software bundle that caters towards gamers, enthusiasts and audiophiles. All the software surrounds the Aorus App Center which acts as the hub with the most notable software coming via the EasyTune which is an overclocking and tweaking utility, the RGB Fusion 2.0 software for customizing the boards RGB LEDs and USB DAC-UP 2 utilities which allows users to alter the power of two USB 3.1 G1 Type-A ports on the rear panel.

The GIGABYTE Aorus App Center acts as its software’s plexus and all other applications cannot be installed without first installing the App Center. This is a positive for users looking to keep software in one easy to use panel, which also offers users access to primary Windows settings from the Control Panel and from third-party applications too. The negative is that users must do something that they may not wish to do; no-one likes applications and software to be forced upon them, even if it’s intuitive and purposeful.

With the Aorus EasyTune software, it allows users to select between four different overclocking modes; ECO, Default, OC and AutoTuning. Eco applies an overclock of 4.7 GHz on a single core, while Default looks to do the same, but with a little more headroom in power draw. The OC mode applies an overclock of 4.7 GHz across all the cores, whereas the AutoTuning profile goes through a 10-15-minute process of rebooting, automatic overclock tweaking and outputs a profile based on what it thinks the overall system can handle.

Users looking to do overclocking outside of the firmware can do so with the EasyTune utility. Within the software is an extensive list of overclocking settings for the CPU, memory and boards power delivery. Options for changing the frequency of external base clock generator, the CPU core ratio per core or all core, primary voltage settings and even memory frequency are assessable via EasyTune. Unlike some overclocking utilities from other vendors, the Aorus EasyTune offers real-time changing without the need to constantly reboot.

The GIGABYTE Aorus Game Boost software allows users to essentially free up system resources such as applications that hog RAM and CPU power. Users can press Ctrl + Alt + B to allow the software to ‘optimize’ the system processes or users can select through the hungriest of programs and close them down manually. The benefit is more likely to be noticed on a lower end system or if users are running highly intensive applications such as Adobe Photoshop in the background without realizing; I certainly notice if Photoshop is open and the software doesn’t offer much more than common sense would dictate.

When it comes to customizing the integrated RGB LEDs on the Z390 Aorus Master, GIGABYTE has equipped the software bundle with the RGB Fusion 2.0 software. Users can select between eight different lighting effects or turn the LEDs off completely. Each of the individual lighting zones and headers can be customized to have their own separate effect/color combination or sync across the board.

For the audiophiles using good quality USB headsets, GIGABYTE has doubled up the two USB 3.1 G1 Type-A ports with the USB DAC-UP 2 technology. What this does is allow users to apply voltage compensation to the ports with up to 0.3 V more through the ports. The voltage compensation defaults at normal variables with the software allowing users to disabled USB bus power completely from both ports. Users can also control and apply voltage compensation through the front panel USB 3.0 header; the software displays two headers, but the board only has a single USB 3.1 G1 header.

While the core software bundle accompanying the Z390 Aorus Master is useful, I don't feel GIGABYTE hasn't utilized all of that focus on onboard audio as they should. Usually with models that incorporate good quality audio options including DACs and amplifiers come with a software package that makes users feel like they are getting a premium product, as well as offering functionality for users to customize sound profiles. Even though the Realtek Audio Console does do this to a degree, a third party software suite downloadable from the official product page and the installation CD would make the bundle more complete.

    Solid 5.0Ghz at 38C, at idle, on my Aorus Master, with F8 BIOS. One of the best motherboards I have ever used. Reply

    And yet a bottom of the barrel Asus board performed better. More phases does not automatically make a VRM better. Reply

    hahahahaha BS...Asus you can cook on it but that is how butthurt Asus fanboys are. CAnt accept that on z390, Asus dropped the ball big time Reply

    for all those phases it sure comes out alot slower than the asus boards Reply

    "During the overclock testing on the Z390 Aorus Master, we had to take a slightly different approach due to some instability as we went through the multipliers with default power settings."

    Yes, yes, and yes. I bought this board back in November on Black Friday due to a great sale New Egg had on it (which surprises me that this review is as late as it is. This board is about 5 months old now). But I simply couldn't figure out how to overclock the CPU manually via BIOS on this board due to crashing loops. I ultimately settled on using the Appcenter EZTune software which placed my 9700k @ 5.1 and ~1.3v, although it fluctuates depending on load (of course). I'm happy enough with a software generated 5.1. But OCing this board shouldn't have been as annoying as it was.

    I'm actually surprised it was near bottom of the barrel for gaming fps though. Bummer. But I like the Mobo all things considered, especially the amount of USB ports it has.

    Oh, and it does have a solid VRM as El Sama stated.

    I'm currently testing the GIGABYTE Z390 Aorus Pro WIFI (on the test bench) and the overclocking is pretty similar in experience. As I highlighted in the review, this board (and the Pro WIFI) are the only boards where I've had to adjust LLC and power settings to achieve 5-5.1 GHz. Reply
  • Cyruskain - Thursday, March 21, 2019 - link

    @gavbon I'm going to attempt to mirror the BIOS changes you did and see where that nets me. I also attempted to adjust the LLC alongside the freq. multiplier, but I continued to get crashing loops. However, there were things from the article you did that I didn't, so I'm curious to try it out. But, at the end of the day, the software netting me 5.1 isn't anything to scoff at. It's pretty impressive for software. Reply
  • gavbon - Thursday, March 21, 2019 - link

    At least the software gave you a stable overclock, to begin with! 5.1 GHz is certainly good, pretty awesome if you ask me! Reply

    You can OC GPU with software but I would recommend against OCing CPU with software, especially Gigabyte software. Google it! Reply

    I have done a bit of testing on this Motherboard both on the test bench and fully integrated into a build. Ring ratio seems to play a role with performance and defaults have changed through-out the bios revisions. Huge variations in performance, CPU voltage requirements and ring ratio defaults.

    Bios F6 defaulted the Ring ratio to 4.8 while later revisions have lowered the ratio to 4.7 and 4.6.

    I have experienced the best bench performance with the 9900k on F6 BIOS ring ratio 4.8 and at 5.0GHZ all core at 1.285 Volts. B-die at 4266 1.5v

    Passes Intel Burn Test very high and maximum. 5.2GHZ @ 1.375 also passes IBT very high on F6 bios.

    On the contrary bios F8e requires 1.325v @5.0GHZ and does not pass IBT @ maximum. Performance is also down if the ring ratio is not manually adjusted back up to 48.

    Buildzoid has a great vid on samsung B-die overclocking on the Z390 Master

    Over on the Gigabyte forum users have complained about XMP profiles and RAM compatibility throughout the bios revisions...

    @Gavin Which bios revision were you using, and did you test DPC latency & gaming perf with different bios revisions?
