ASRock X299 Gaming i9 BIOS

The ASRock UEFI BIOS for X299 is similar to past iterations in look and overall feel.  By default, due to the 'professional' nature of this board, users are greeted by the 'Advanced Mode', which allows more options and flexibility than Easy Mode. Pressing F6 toggles between the modes.

In Easy mode, the screen shares high-level information including the type of CPU installed, DRAM information, storage configuration, fan status, temperatures of the CPU, motherboard, and CPU voltage (it reads input voltage), boot priority, BIOS flashing, and FAN-Tastic Tuning.

While editing more advanced features are saved for advanced mode, some items are configurable here. For example, XMP profiles can be enabled, and configuring a RAID mode can be changed with a click of a button on-screen. There are tools for flashing the BIOS, changing pre-configured fan profiles, and changing the boot priority are all editable functions in Easy Mode. Any other adjustments will have to be made in Advanced Mode.

Jumping into advanced mode provides a way to see and edit a lot more items from the BIOS. The Fatal1ty themed UEFI is mostly black and red with the text in white. Across the top is a menu consisting of several sections: Main, Overclock Tweaker, Advanced, Tool, H/W Monitor, Security, Boot, and Exit. The default landing page is the Main screen. Not terribly informative, but it shows the UEFI version, processor statistics, as well as the populated memory slots. From this screen we are able to access My Favorites, which can be populated with the UEFI options of choice by pressing F5.

The OC Tweaker section is where overclocking options for the CPU, DRAM, Voltage, and FIVR are found. The CPU Configuration section shows options for adjusting the CPU Ratio, BCLK, Mesh, and a slew of other CPU related options which will remain unused for most users. In the DRAM section the user can enable XMP, change the memory multiplier, and have access to adjust the four major timings, as well as dozens of secondary and tertiary timings. The Voltage Configuration selection is where major voltage options such as CPU Input Voltage (input voltage for the IVR), CPU Load-Line Calibration, System Agent and I/O voltage for the memory controller, and voltage for each pair of DRAM channels can be edited. Last, the FIVR configuration gives control over the main voltage heading into the processor (which then separates it into lower voltages for each clock domain). Items like the Vcore voltage mode, CPU Mesh voltage, and other offsets are found here. 

If one touch overclocking is your thing, ASRock offers this with the Load Optimzed CPU OC Setting. For the 7900X installed there are options for Turbo 4.2 GHz, 4.4 GHz, 4.6 Ghz, and 4.8 GHz. In a nutshell it takes all cores and overclocks them at the same speed, bypassing normal turbo functions. It did use slightly more voltage than needed when compared to manual overclocking at the 4.4 GHz setting, but otherwise it was stable and worked fine. 

The Advanced section of the X299 Professional Gaming i9 is a list of folders/sub-menus each having adjustable options to the subsystems of the motherboard. It offers control over the CPU and Chipset configurations, Storage, and USB among other options. The 'Tool' tab option lists several features, such as RGB LED to set the RGB lighting, an Easy RAID installer to quickly setup RAID arrays, as well as UEFI utilities for flashing the BIOS (via internet or local Instant Flash). It also has a function to securely backup the UEFI. The H/W Monitor screen shows live readings of temperature sensors, fan speeds and voltages. Moving down in this section allows for tweaking of the motherboard fan headers for fan and pump speeds.

Security, Boot, and Exit are fairly self-explanatory. If a password is needed required at the BIOS level, the Security section is where that can be set. The boot section covers exactly that, most anything that touches the boot process. From drive priority, to speed of the boot, to having, or not, a full screen logo on boot. The gallery below shows all the UEFI screens. 

ASRock X299 Gaming i9 Software

The included driver DVD comes with all the drivers a user needs to get started. It also contains some Google freeware (Chrome and the Google Toolbar) on the main Drivers and Software page. Moving over to Utilities, this section includes the ASRock RGB LED, and the Sound Blaster Cinema 3 audio application. Last is the information tab, where owners will find links to soft copies of the user’s manual, quick installation guide, a RAID installation guide, and Intel RST guides. 

ASRock App Store

Once the drivers are installed from the disk, a user can install the App Store application and confirm all drivers are up to date in the BIOS & Drivers tab. If they are not, the drivers can be updated by selecting the driver that isn’t and pressing the Update button. The Apps section is has software downloads for Sound Blaster Cinema 3, the RGB LED Utility, and some sponsored downloads for Norton Security and a couple of slot games. 


If system monitoring and overclocking from within windows is the preferred method, ASRock has its F-Steam application. From within the program, there are three preset modes users can choose from: Performance, Standard (default), and Power Savings. These options manipulate power savings and turbo modes, but does not overclock. The OC Tweaker section has the necessary manual options from voltage control to BCLK and CPU ratio. The System Info section displays informative details on the CPU speed including BCLK and CPU ratio, fan speeds and temperatures, as well as voltages. Also included with F-Stream is their FAN-Tastic Tuning section where motherboard connected fans can have their fan curves adjusted from within windows.


The ASRock RGB LED application gives users the ability to change the color, style, and speed of the integrated LEDs under the PCH, or control of external RGB LEDs when attached to the two headers. It has several modes/styles to choose from as well as full control over the color with RGB sliders. 

Sound Blaster Cinema 3

The Sound Blaster Cinema 3 software suite allows manipulation of the audio ecosystem. Users are able to control aspects of the surround sound implementation, bass boost, sound crystalizer, and dialog plus to tweak the sound to the user's preference. It has three different modes, music, movies, and games, for setting options within each type of playback situation.

    Does it support intel's latest and greatest dual core i3 HEDT cpu? If not - no buy.
  • duploxxx - Tuesday, September 26, 2017 - link

    why test on a stupid 7900X cpu?
  • duploxxx - Tuesday, September 26, 2017 - link

    bring the 16-18 core and show how the dual memory controller is handling the games, after all this is a gaming board ....
  • ddriver - Tuesday, September 26, 2017 - link

    Yeah, and don't forget the games that scale up to 16-18 cores.
  • JeffFlanagan - Tuesday, September 26, 2017 - link

    For some reason, people feel the need to stream their games on the Internet, so that only leaves 15-17 cores for the game to use.

    It seems like an i5 is still a much better value for a gaming machine since most games use very few cores.
  • duploxxx - Wednesday, September 27, 2017 - link

    the reason i ask is because threadripper reviews all over the net were hammered with the poor gaming benchies en the reason for specifc settings. guess what, no gaming benchies on the HCC designs from Intel that have the same memory disadvantage.
  • OhWhateverOnceMore - Tuesday, September 26, 2017 - link

    "i9" ...ok...
    "Professional" ... uh uh...
    "Gaming" ... /r/hmmm
  • TEAMSWITCHER - Tuesday, September 26, 2017 - link

    Is there an Intel co-marketing kick-back for having a "Gaming" branding? You see it everywhere...
  • oRAirwolf - Tuesday, September 26, 2017 - link

    "Curiously, for a motherboard which has "gaming" in the title and having three network ports, we were surprised not to see a Killer Network based NIC which finds its way on to several other gaming motherboards. Network traffic shaping is still possible through software, although Rivet Networks would likely claim they offer an optimized solution if their chip had been used. Perhaps a combination of an Intel GbE, Rivet Networks Killer E2500 GbE, and an Aquantia 10GbE which would have encompassed more of its tarket market."

    Wutness? Why on Earth would you want to see Killer on a gaming board? ASUS has shown through their own testing that Killer NIC's are trash:

    That aforementioned paragraph seriously makes me question the legitimacy of reviews on this site now. It is common knowledge that Killer is absolute and utter trash.

    Oh you beat me to the point here. This is one of very rare times when I'd agree that there appears to be a certain amount of institutional bias at Anandtech in favor of Killer NICs. If you do a search for the string "Rivet Networks" in AT's search box you can find this article from September 2016:

    It looks like that was sort of ground zero for that opinion and it's stuck since. In the comments of that article (disclosure - I was a participant with cynical views of Killer NICs even back then for reasons I make clear in those comments) there was discussion about reviewing and analyzing the E2500. Anandtech has never presented such a review or supplied readers with any data supporting the idea that Killer NICs are somehow superior or worthy of being sought out by consumers. Despite lacking reliable test data, there's still unexplained support in the form of hint-dropped lines like the one you've quoted that imply a certain subset of readers should be seeking out Killer NIC-equipped products or that its somehow unusual that a premium motherboard omits them.

    I find the whole thing does hurt Anandtech's credibility. If there's data that supports a Killer NIC being a better option, gather it and publish it. Don't assert and insinuate without any substantially supportive information to a group of people (gamers in this case) without being able to back up those claims. Killer NICs can be acquired for testing. Maybe Rivet's people would supply a product for testing. If Rivet doesn't or does and Anandtech doesn't test it, then what else do we have to go on? Consumers in the target audience are already broadly suspicious of the benefits Rivet claims Killer NICs offer to the point where it seems almost delusional to boost them in a motherboard review.
