The Biostar X470GTN Racing BIOS gets a visual overhaul over the previous X370GTN model, although both versions of Biostars GTN BIOS have very similar traits in that they are both relatively basic. The new UEFI BIOS on the X470GTN is certainly more defined in that the panels and menus flow better and look more visually appealing. The most notable improvement is the menu bar with proper descriptions as to what each menu is titled as the X370GTN relied on icons as opposed to text-based titles. 

Entering the initial splash screen after pressing F2 automatically brings users to the main menu, which is a basic list of information regarding things such as the BIOS’s compliancy, the model name, the BIOS firmware version currently installed and the build date of the current BIOS version. Below this is information about the installed memory capacity, but no information on individual populated slots, nor whether the memory is operating in single or dual channel is noted. On the left-hand side of the screen is a panel going from top to bottom listing information relating to processor speed, memory speed, current system temperature in real-time from the onboard temperature sensor and the current date and time.

The advanced menu allows users to change some of the more complex settings such as security settings within Trusted Computing and enable, or disable ErP and configure power-related settings. The SATA configuration setting allows for the onboard SATA controller to be enabled or disabled, as well a basic hardware monitor which consists of a basic list of readouts ranging from CPU temperature, the system monitoring sensor temperature, as well as CPU fan speed and current voltages. The more comprehensive set of customizable DDR4 memory options can also be found here such as enabling ECC support (set to automatic by default) which Biostar doesn’t actually state if ECC is actually supported within their manual or limited QVL supported listing.

In the chipset menu, users can enable or disable the various controllers on the board.

The O.N.E area contains options required to overclock processors, but just like with the BIOS found on the X370GTN motherboard, there were a few areas that could be improved upon. The CPU settings allow for multipliers such as x34 for 3.4 GHz and x42 for 4.2 GHz as would be expected, but the CPU core voltage works from voltage offsets as opposed to set values. This would be acceptable to work from, but there are no indications of what the base voltages actually are so inexperienced users could quite easily be left scratching their heads in dismay. This method is very primitive and not attractive to even the most experienced users as it requires extra guesswork involved when the process could and should be relatively straightforward. This makes it doubly worse for anyone trying liquid nitrogen overclocking.

The BIOS didn’t let us take any screenshots with any of the dropdown menus selected which was slightly disappointing, but selecting the Memory Clock Mode opens up the ability to set the installed RAMs X.M.P memory profile, or select from a range of memory frequency dividers which ranges from DDR4-1333 all the way to DDR4-4200 which is far beyond the maximum supported speeds on the box. 

While not as clean and crisp as some other vendors BIOS implementations, the overclocking settings do seem to work well when set within acceptable variables and users looking to make more comprehensive memory customizations can even set a variety of sub-timings in the DRAM Timing Configuration menu.

Another annoyance within the BIOS was the inability to take screenshots of the Vivid LED screen and the Fan customization panel; the Vivid LED screen can be accessed by pressing F6 within the BIOS. The Vivid LED options and panel on the X470GTN is a very noticeable improvement over the one included with the X370GTN as the new screen includes a selectable color wheel which replaces the older style and archaic numerical based RGB options. Users can select between three different lighting modes as well as having the ability to turn them off completely. Users can also customize the colors of the two RGB 5050 headers the board features which is a nice feature to have, but there are no options within the BIOS to sync across the three available areas which is a rather unfortunate area to neglect in today's RGB crazed market.

The fan customization screen can be accessed by pressing F5 and allows users to select between four different settings which include quiet, aggressive, manual and full on. With the manual control mode selected, users can set their own custom curve profile with five different points of customization available. The board has a total of two headers including one for the CPU and another for a system fan, which is very basic and there is nowhere in the BIOS to select between DC or PWM mode, giving the indication that what you see is what you get, unfortunately.

While the BIOS on the newer X470GTN motherboard in comparison to the previous X370GTN model is a clear improvement, some areas which did require some work haven’t been addressed, whereas other areas such as the LED section have been improved. The BIOS does look newer on this model in contrast to the X370GTN, but unfortunately, it’s still a little antiquated and efforts to improve the usability hasn’t been done to levels expected. The Vivid LED options are certainly notable and I applaud Biostar for including usable settings for novice users, but the overclocking options are still very outmoded in comparison to the other big four vendors and while a clear aim of Biostar has been to create a BIOS similar in style to the other manufacturers, more focus should have been paid towards developing a better overclocking system with set variables.


The software package supplied with the X470GTN is far from extensive, but just like the company has done with the BIOS, Biostar has looked to improve upon what it already has. The more prominent of the utilities is the Biostar Racing GT Software which has had a major visual overhaul. Also included is the Biostar BIOS Screen Updater, the Biostar BIOS Update software and a generic Realtek HD audio manager utility.

The Biostar Racing GT software offers users a variety of different functions and features in one basic but visually pleasing place. The different menus include System Information are self explanatory, such as information relating to currently installed hardware such as the processor, memory and lists current CPU core speed, memory speed, memory timings and even the installed firmware version. The Smart Ear menu allows users to increase or decrease volume, just like the volume control within the Windows Task Bar which seems pointless, but it’s basically this but with a fancy looking GUI. GT Touch is a little different and allows users to select between three different system states, Normal which is essentially a balanced mode, Eco which is designed to be more power conscientious and the sport mode which Biostar states to provide the highest level of system performance.

Just as within the Vivid LED DJ section in the BIOS, the Racing GT software also allows RGB customization within the operating system. The BIOS screen sort of mirrors the software with the options to select between the three different lighting modes across three different zones, with the ability to turn off the LEDs completely at the touch of a button. Just as with the BIOS, there is no option to sync the effects and colors across all three available areas of customization which again, is disappointing to see given the maturity of RGB over the last couple of years.

The OC/OV section stands for Overclocking and Overvolting with options here available for overclocking within Windows. Software from the other big vendors offer much more customization than Biostar as the only option available for change in the OC section is the CPU ratio limit which goes up and down in 100 MHz increments. The OV section allows for the adjustment of a variety of voltages including CPU Core Voltage, DDR Memory Voltage and even CPU SoC Voltage which is paramount for overclocking the Ryzen based APUs.

    Thanks for the Power Delivery Comparison. That's something that is hard to check for if not in a good review. Keep up the good work.

    Thanks Marlin, appreciated! We're looking to further add to this going forward
  • MrCommunistGen - Wednesday, October 24, 2018 - link

    I actually really appreciate this as well because this kind of information has been hard to come by in the past. I had some questions regarding the included table.

    The ASRock B450 Gaming ITX/ac is listed in the table as using the same controller (ISL95712) in "6+2" mode. The spec sheet for ISL95712 states that it is up to a 4+3 controller. The table also doesn't list any doublers. Doesn't this make the board a "big 3+2" rather than a 6+2?

    I didn't look at any of the other boards in the table closely, but I was just doing a bunch of reading on the ASRock ITX boards recently and so I was looking very closely at that line in the table.

    Thanks for the review!
  • TeutonJon78 - Monday, October 29, 2018 - link

    It would help more if it was accurate.

    The ISL95712 maxes out at 4+3 phases, so it can't run in 6+2 as listed in the chart. On the ASRock boards, then run a 3+2 setup but with two sets of MOSFETs and chokes in parallel, but not doubled. There is only one capacitor per phase. It helps keep the temps down by splitting the current, but it's still only a 3 phase design.

    Plus, it would be more meaningful if the chart was for similar style boards rather than a smattering of different form factors.In this case, the other m-ITX boards.

    Just thinking about POST times, when UEFI was the next big thing we'd been repeatedly promised that it'd allow 1-2s POST times because unlike BIOS it could start components up in parallel instead of 1 at a time.

    While current boards do post faster than their predecessors the speedup never came close to meeting the hype. Does anyone know why reality fell so short of the promise?
  • Dragonstongue - Wednesday, October 24, 2018 - link

    likely because there is so much crud to siphon through before it completes the process
    the same from going to post to OS log screen to fully booted OS

    am sure there are ways to "speed it up" but often those methods come with chance of something terrible happening and not knowing what took place.

    be happy the new stuff is WAY quicker and more energy efficient then the old 9/10 so even if it takes a wee bit longer to boot up, patience come to those whom wait.

    SSD helps that much I know, but as far as only 1 to 2s to finish post..umm I personally never heard of such promises, the board I am using is AM3/3+ M5A99X EVO (v1) which uses a UEFI based bios design and just going from HDD to SSD made post much quicker and a few changes I made as well to speed it up also helped.

    I personally have more issue with how long it takes to shut down then be fully booted up ^.^

    As fun as it sounds there are 10 year old systems that run on UEFI. I must say, that boot times are much quicker on them, while supporting much wider range of hardware. Feature-wise it's hit or miss, I have 9 year old board that's capable of booting from NVMe, thanks to drivers being easy to punch in, but it won't allow user mode to write to boot manager area, thus linux bootloader installation will fail (I just have to point the path manually from the UEFI setup).
  • JoeyJoJo123 - Wednesday, October 24, 2018 - link

    Ahmdal's Law, in a way. There is a relative speedup to be had, but desktops don't need to be shutdown/restarted extremely often. Often just letting it go into sleep mode is adequate for me, and leaves my workspace in exactly the same place it was before.

    For laptops or other mobile devices, shutting down is more necessary when moving between work environments, (given that sleep mode will drain battery life over time anyways, hibernate isn't ideal and can clog the main storage disk with a file equal in size to your capacity in memory, etc.). For mobile PC devices, I have personally noted that boot times are appreciably fast.

    Also, personal anecdote, but I've had boards that when set to options for "fast booting", not only would it refuse to take in DEL or F11 prompts to get into BIOS screen when booting up, but it would go from a stable (normal) bootup, to a blazingly fast crash/reboot cycle for 5 loops before landing me back on the BIOS page with stock settings. This is before and after BIOS updates.

    Personal opinion, but I just think it's intentional that for the enthusiast PC market that vendors don't _want_ to speed up boot times because the same users buying these motherboards are enthusiasts likely willing or needing to occasionally go into BIOS and change boot order of disks, or do overclocking features, etc. and making sure users can actually get into BIOS easily and reliably (hence a slow boot with ample time to opt-in to boot to BIOS) may have been one of their intended design goals.

    There is reverse effect in action: amount of stuff that is set to initialize during boot is staggering. I'd asku you to find 1MB legacy BIOS, while 16MB UEFI is not uncommon, and I am in a possession of motherboard that has 512 MB SPI flash for it (not 512 megabits - half a gigabyte). Then, amount of stuff you can boot from went trough the roof. On top of drivers for everything that need to start up and register, there are at least three different frameworks that monitor hardware and need to set up.
    Then, every damn power controller, voltage regulator, thermal zones, OC chips are smart need to boot up too.

    Then, amount of memory skyrocketed - if you remember old BIOS happily running memcheck kilobyte after kilobyte, until it reaches that 64MB, and compare to you 64GB system, that still gets a cursory check, despite memory NOT being 1024x faster.

    You can cut your boot time down, if you properly disable CSM, disable external controllers (or at least disable their boot rom), properly set up boot sequence to UEFI bootloader, and use GPU with a BIOS that supports GOP, and finally enable fast boot, your PC WILL boot in ~2-3 seconds plus OS.

    On the other hand, while handling servers I am accustomed to boot times on the orders of 20 minutes at extreme case.

    My system (H87 with NVME boot mod BIOS) gets to windows faster than my 4k DP monitor wakes up from standby. The DVI one is a bit faster. I guess around 3 seconds maybe?
