ASRock Fatal1ty X99 Professional Motherboard Review

Firstly, we are pleased to report that our NZXT Avatar S mouse worked to its usual standard in the ASRock X99 UEFI. We’ve found our NZXT Avatar S to be the most troubling mouse with UEFI support, so when it functions correctly in the interface, that is usually a good sign for overall mouse support.

ASRock's X99 UEFI is consistent across its motherboard line-up (hence our screenshots being taken from a previous review). There are subtle differences between the versions, the most notable of which is a different background colour depending on the motherboard's series. The interface uses a 1920×1080 display resolution.


The Main page displays information about the system components. There is a My Favorite section that gives users quick access to their most desirable settings.

UEFI-OC-tweaker UEFI-OC-tweaker-2 2_1-OC-tweaker-3

The OC Tweaker page controls access to the board's numerous overclocking-related sub-sections. I like the way that ASRock has split its main overclocking sections into separate folders. This keeps the interface clean and makes the desirable settings easy to find. It also proves that ASRock is listening to feedback and taking steps to improve its UEFI user experience.

Overclocking profiles designed by one of the world-leading professional overclockers – Nick Shih – can be loaded from the UEFI. There are also some less extreme overclocking profiles set by ASRock’s engineers.

Up to five customised user profiles can be saved to the board's internal memory. I feel that five profiles is sufficient for a motherboard that is not intended for competitive overclocking. A USB flash drive can be used to transfer profiles to and from the board.


The standard set of parameter and ratio settings are provided under the CPU Configuration section. ASRock also adds a CPU TJ Max input which is a unique setting allowing users to change their processor's thermal throttling temperature. Approach this setting with caution and appreciation for the involved risks.

UEFI-DRAM-1 2_3-DRAM-2 2_3-DRAM-3 2_3-DRAM-4

There is a strong range of memory overclocking settings provided in their specific sub-section. Users can adjust their DRAM frequency and voltage in addition to viewing their kit's rated, and applied, timings.


A large number of pre-tweaked (presumably by Nick Shih) overclocking profiles are included in the memory section. I would advise caution before loading any of the profiles as a test to see what your memory is capable of – anything more than 1.50V is particularly high for DDR4 and should be approached with caution.

2_4-FIVR-1 UEFI-voltage 2_5-Voltage-2

Settings relating to the Haswell-E processor's Fully Integrated Voltage Regulator (FIVR) are given their own section. Here users can apply the primary voltage settings that will deliver their quick-and-easy overclocked settings.

Moving over to the Voltage Configuration section is where users can fine-tune the parameters to squeeze even more frequency out of their components.

ASRock typically allows users to opt for automatic, manual, or adaptive voltage configurations.


The Chipset Configuration section is useful when ensuring that expansion slots are receiving the correct PCIe bandwidth.

Storage interfaces and their installed drives can also be controlled.


ASRock includes a number of convenient tools in its UEFI. Users can rapidly apply a number of system configurations and drivers can also be downloaded via the interface.

Instant Flash, ASRock's simple BIOS updating tool, scans through one's USB flash drive to search for the relevant BIOS file. While this sounds good, with the tool's ability to scan all the way through your flash drive until it finds the relevant BIOS profile, users with a large amount of data on their drive could find the search time to be in the order of minutes. There's little wrong with a manual folder search.

UEFI-system-browser 4_1-tool-3

System Browser is a convenient tool that displays which components are connected to the motherboard. The tool is particularly useful for troubleshooting purposes; if, for example, a memory stick is faulty, it will not show up in the System Browser window.


ASRock includes an extensive set of voltage, temperature, and fan speed readings on its HWMonitor page. This is where the pair of Nuvoton SuperIO chipsets and numerous board-placed thermal reading points prove valuable.

UEFI-HWMon-3 UEFI-Fan-tuning

There are two ways of setting fan speeds in ASRock’s UEFI. Users can either select from pre-defined profiles, or they can fine-tune their own custom fan speeds. There’s the old way of doing this – by selecting the relevant choices from multiple drop-down lists. Or there’s ASRock’s modern FAN-Tastic Tuning visual tool.

I was very impressed by the capabilities of the FAN-Tastic Tuning tool (the cheesy name, on the other hand…). The five-point curve can be adjusted to an individual’s preference with a large range of freedom; a CPU temperature as low as 30°C can be set, while the fan can run at 0% or 20-100% in 1% increments. And what is particularly impressive is the board’s ability to completely shut-off a controlled fan below a user-defined temperature threshold.

The level of control FAN-Tastic Tuning provides is excellent, especially when a fan can be set to stop spinning in order to provide a particularly quiet system.

UEFI Summary

In the latest motherboard platform launches, ASRock has worked hard to improve its UEFI. The company has moved to a Full HD – 1920×1080 – resolution, the layout has been re-ordered, the styling has changed, and new-and-improved tools have been designed.

ASRock now has a UEFI that I would deem to be right on the heels of Asus' solution, making it the second best interface on the market (in my opinion). And there are some clear areas where ASRock's interface trumps that of Asus' (System Browser, for example). What is equally positive is that ASRock has clearly listened to user feedback that said the UEFI layout needed improvement.

The interface is well laid-out, easy to use, and full of relevant user-customisable parameters.

AMD has detailed its new compression technology to reduce the storage space required for installing games. This innovation, called Neural Texture Block Compression (NTBC), compresses high-quality textures while maintaining "reasonable quality". According to AMD, NTBC can decrease a game's storage footprint by up to 70%, reducing the installation size of titles like Call of Duty from 150GB to 45GB.

  3. You guys make some weird choices. You have trouble using the 2666MMhz g.skill memory and opted to use memory from Corsair, but later in the review you say that the 3000Mhz G.Skill memory was performing fine. So why not do the main tests with the 3000Mhz memory instead of 2666Mhz memory from another manufacturer. It seems to me that the 3000Mhz and 2666Mhz memory modules of G.Skill are closer to each other than 2666Mhz memory from different manufacturers..
