The Z97 BIOS from ASRock is reskinned from a black and starry background to a blue outlook coupled with a crystalline figure in the background. Back in my review of the Z97 Extreme6, I mentioned that I preferred the black background as it was easier to see the options at a quick glance, and the options at the top had high definition icon images to help distinguish them. On the Z97E-ITX/AC, these icons have been reduced in size and the tabs at the top use a fixed-width font, which is something other motherboard manufacturers are moving away from. For users with 1080p monitors, the BIOS offers a ‘Full HD UEFI’ mode which will improve the resolution.

One of the newer features in the ASRock BIOS will be the My Favorites option, shown on the screenshot above. Similar to the implementation of the other manufacturers, users can select options from the BIOS to place into the My Favorites menu for ease of use.

Here are a few options I quickly put in to show it working as it should, along with an Active Page on Entry point that allows enthusiasts to bypass any entry screens and go straight to the options that matter. Using this in conjunction with the My Favorites menu should be a no-brainer for extreme overclockers.

When it comes to the overclocking menu, motherboard manufacturers split into two groups. Some will partition off groups of options into separate menus, whereas others will spam a list of everything, hopefully with a sense of order. ASRock offers for the latter, as it took several screenshots to cover the CPU configuration, DRAM Timing, FIVR configuration, and the Voltage configuration.

Even for me, that is a little excessive. ASRock might consider putting each of these options into submenus and having copies of the more vital ones (CPU Ratio, BCLK Frequency, XMP, CPU voltage, CPU load line calibration, DRAM voltage) out on the main OC Tweaker page.

At the top of the OC Tweaker page are the Optimized CPU OC Settings, or in plain English ‘the automatic overclock options’. Here we get 4.0 GHz to 4.8 GHz offered in 200 MHz jumps:

The options use an internal look-up-table that ASRock would have configured, based on its own testing. These should be the best voltage combinations for each setting in order to ensure that most processors are catered for at each step. Our analysis of these is in the overclocking section of this review.

Almost all of the options in the BIOS has an associated description listed on the right hand side. While the motherboard officially supports fast memory, the memory options provided by ASRock go all the way up to DDR3-4000:

There is also a new option for the memory called ‘DRAM Performance Mode’, which states that it gives higher performance for memory but does not say how. The DRAM sub-timings are found in the DRAM configuration menu.

Users interested in disabling the onboard controllers should head to the Advanced -> Chipset Configuration menu, where the Audio/LAN ports can be adjusted:

In order to confirm if the M.2 x2 is in use or the SATA Express, the Storage Configuration has the option to force one or the other:

Most of the interesting extra options are found in the Tools menu.

System Browser is now a staple across most of the motherboard manufacturers as it allows users to see what is installed and detected at POST. Because of the M.2 port on the rear of the motherboard, we also get to see this as part of the diagram:

The Online Management Guard (or OMG) is a tool to disable the network ports during certain times of the day, although it does not stop someone changing the rules or the BIOS clock in order to get around it.

The Tech Support function allows users to submit bug reports when things go wrong, although the system has to be set up via the network configuration option. This means that any system that issues an IP address from a DHCP server should work, rather than via connection sharing. Having the network options enabled also allows users to download updates for the BIOS via the BIOS.

The dehumidifier function sets up a time interval for the system to enable the fans after shutdown. This is used in environments with high humidity whereby the air in the case can be a lot warmer than the air in the room and as the room cools for an evening water will condense on the inside of the case. With this function, the system will keep the fans running after shutdown so the air inside and outside the case can equilibrate.

The H/W Monitor tab lists the temperatures, fan speeds and voltages of the system, as well as the fan options from the BIOS:

While I appreciate the multi-point gradient system, there is something fundamentally wrong with the wording here. Without testing the fan to find the RPM to power applied profile, you cannot control the fan speed accurately. What ASRock means when they say fan speed here is fan power, which is a different word with a different meaning. It would seem that the software team, which do test the fans to provide fan profiles, and the BIOS team are not talking to each other on this front.

Elsewhere in the BIOS are the boot options, the fast boot options and the security settings. There is no Boot Override function unfortunately.

ASRock Z97E-ITX/AC Software

Similar to the BIOS, there is little difference between the software used on the Z97E-ITX/AC and the Z97 Extreme6 we reviewed just after the launch of Z97. The newest part of the package is ASRock’s own application interface, the App Shop. This is essentially a Google Play Store / App Store for ASRock to put in their own choice software, updates to their software, or perhaps a few sponsored items. As shown in the screenshot below, we get several of the standard ASRock software installations as well as Chrome and a few APAC based FTP games:

This sets a somewhat worrying precedent in case other manufacturers might do the same. It might not be all bad, given that these are simply PC game installation files to be downloaded, as if you went to the website of the company that made them. There does not seem to be any mechanism for buying applications, so at the minute everything posted on the ASRock App Shop is free.

The App Shop does also offer a system update feature for BIOS and drivers, although it offered none when I attempted to use it:


However everything else from ASRock is tunneled through their A-Tuning interface. This is relatively similar to our previous ASRock Z87 reviews where the first screen we come to is the Operation Mode:

The default position is Standard Mode that will run the CPU as per normal. The Power Saving mode will reduce the CPU to 800 MHz and will slowly ramp the speed up as more performance is needed. It will require a good 10 seconds of full throttle to get to full speed. Performance mode disables any idle states, but also opens up another menu for more options.

The EZ OC options are similar to those in the BIOS, and Auto Tuning at the bottom will perform a series of overclocking tests to determine an overclock for the system. 

The next tab along is the Tools tab, which similarly to the Tools tab in the BIOS is the main hub for all the extra ASRock options.


A common theme with almost all motherboard manufacturers is to include some form of RAMDisk software with the motherboard, often negating any pay software currently on the market. The ASRock tool allows users to recover a RAMDisk on boot and allow the RAMDisk to act as a temporary file store, or a regular file store as needed.


Another theme in motherboard software is to implement some form of network packet prioritization, allowing users to select which programs have network priority (e.g. VOIP over games, games over downloads). Most of these solutions use a custom front end to a cFos back end, as is the case with ASRock:

Fast Boot

With the new UEFI system implementation, a motherboard can bypass some initialization procedures for devices that conform to UEFI specifications. This also requires a UEFI aware OS, such as Windows 8, to ‘instant’ boot, but other Windows operating systems can take advantage of some optimizations. For Instant Boot users, there is an option here to reboot the system straight into BIOS as well.

Online Management Guard (OMG)

The OMG tool from the BIOS is also available in the software, allowing users to restrict the times when the user can access online functions. In this implementation we also have a password protection system to prevent access.

FAN-Tastic Tuning

The fan controls for the ASRock motherboards use a fan test to provide the user with a power to speed look-up table to help design their fan response profiles. Like the BIOS ASRock has confused the FAN Speed (%) in the graph with Fan Power in the look-up table. There needs to be some basic mathematics done here to do the conversion and make it physically accurate.


As with the BIOS, the Dehumidifier option in the software allows users to keep fans running after a shutdown for a fixed length of time.


In some environments, logging into a machine requires a USB key to identify the user. ASRock’s USB Key does the same thing, allowing the user to assign their profile to a specific USB device such that when it is plugged into the machine, it automatically logs the user in. Just remember to take the USB stick with you when not in use, or make sure that pesky housemate does not get hold of it.

DISK Health Report

I know my early generation Samsung PB22-J 64GB in my netbook is throwing up errors at boot time about SSD life. In order to help diagnose these issues, I need to download and obtain software that reports the flags in the device. ASRock has now added this to the software bundle to bypass the online hunt.

OC Tweaker

For manual OS overclocking we have the OC Tweaker tool which emulates the OC Tweaker menu in the BIOS. All the options are in one big long line; however there is now a pullout section on the right hand side regarding CPU frequencies to show the current state of the system.

System Browser

Similar to the BIOS tool, the System Browser lets the user see what is installed into the system. Should a stick of memory, for whatever reason, stop working users can see it with this software.

Live Update

Alongside the updating tool in the App Shop, ASRock has added a tool in A-Tuning to do the same thing. Here we can select which server to go for as well to get the best connection speed. One feature I want to ASRock add is to display the size of the update before downloading, in case the software is large and my bandwidth limit is small.

    Great article, you read my mind with this, Im planning on an ITX form factor for my next build
  • Zap - Wednesday, July 23, 2014 - link

    Do it! Unless you have a need for more than six HDDs or more than one graphics card there is little reason to go bigger and have a mostly empty case.

    Alternately there is also the little loved micro ATX. Not as "normal" as ATX and not as sexy as mini ITX, but IMO a very good alternative that gives you room for dual graphics, or some expansion cards.
  • PICman - Wednesday, July 23, 2014 - link

    Excellent review. Every time I see a review of ITX boards I'm amused by the giant 2x24 power connector plus an additional 2x2 or 2x4. Every other connector on the original IBM PC has an updated version. Has there been any discussion of a smaller power connector?
  • Aikouka - Wednesday, July 23, 2014 - link

    I was working in a Dell workstation a few weeks back, and I was rather surprised to see that it didn't have a standard ATX power cable. Its power cable was probably about half the size, and if I remember correctly, the motherboard also provided a connector for a cable that provided power to the hard drive(s).

    I would definitely like to see someone be willing to revamp the power delivery as dealing with that monstrous cable is definitely my least favorite part -- especially on cases with too little room in the back!
  • DanNeely - Wednesday, July 23, 2014 - link

    Dell's been using proprietary cables on/off for the last 20 years. I'm glad the current version uses different connectors though. IN the past they've had proprietary cables using AT or ATX standard sockets but with different pinouts so you'd smoke your hardware if you didn't realize it and tried to use a standard PSU as a replacement.
  • DanNeely - Wednesday, July 23, 2014 - link

    I've jumped on my soapbox more than once grumbling about the stupidity of a cable that mostly provides 3/3/5v power when the death of legacy PCI has removed the last significant 3.3v component and 5v is only still used for USB more than once in the comments here.

    But between the failure of BTX and the fact that the desktop market is generally seen as being in terminal decline I'm not optimistic about the likelihood of ever getting a 12V centric CTX PSU standard. If pigs ever do fly though, instead of mashing the entire 4/8pin 12v connector into the cut down remnant of the 24pin cable, I'd rather see the main connector only have enough 12V to run an full power CPU+IGP (or lower power CPU + discrete GPU) based system, with the extra power for a full power CPU and PCIe GFX card in a separate and optional cable: Both to keep cost down for lower end systems, and because the 24 wire cable is a major pain to route because of its thickness.
  • PICman - Wednesday, July 23, 2014 - link

    While we're dreaming, we might as well make the voltage 24 or 48 V to reduce the current and improve the efficiency of the switching power supply.
  • DanNeely - Wednesday, July 23, 2014 - link


    Just rationalizing the pinout would be a much lower impact change and could be done with adapter cables in both directions for reasonably current hardware (most of the 3.3/5v capacity in the 24pin is unused on both sides of the cable).

    Unless PCIe refreshed to use the higher voltage as well (and for a number of transition years in any case) we'd still need to provide a lot of 12V power. The USB charging committee's one cable to bind them all goals include 5A@2v power (for faster tablet charging and for low power laptops) which'd bring an additional long term need for significant amounts of 12v into the system. They also want a 5A@20v step for mainstream laptops; so if we did shift to a higher DC voltage that might be a better option instead.
  • The_Assimilator - Friday, July 25, 2014 - link

    24VDC or even better, 48VDC needs to become the new industry standard immediately. When you have a card like the 295X2 that requires 600W but can only pull that over a 12V line (=50 amps!!!), you have an obvious problem. It's one I fear only Intel can solve, the question is do they have the determination to do it?

    Personally I believe that the PC industry will embrace a new power delivery standard. It means everything will have to be redesigned, which means they get to sell more products. The successor to ATX (which is not BTX) could very well be the boost the PC industry's been looking for.
  • Mr Perfect - Thursday, July 24, 2014 - link

    If they ever did change things, any reason why they couldn't just pump in one 12v plug and then let the mother board do DC-to-DC conversion for other voltages? Smaller embedded boards do this, but I don't know if it would scale up well.
