ASRock Z87 Extreme6/AC BIOS

Over the last few ASRock motherboards I have reviewed, the BIOS has been steadily improving into something aesthetically pleasing as well as easy to use with a lot of additional extra features.  ASRock’s mentality over the past couple of years has been to attempt lots of little minor adjustments and see which ones pique the interest of its consumers, with a few major additions here and there.  In the BIOS itself, we have an almost high-contrast setup (which I prefer) which makes it easy to read, along with high definition images where necessary.  The only thing really missing is perhaps a persistent ribbon of information regarding the motherboard name, CPU used and memory installed, with speeds of each.

The entry screen to the BIOS is initially our Main screen, which gives some basic info on the system at hand: motherboard name and BIOS version; CPU name and current speed; total memory installed along with DRAM slot detection and current speeds.  I would prefer some additional information here as well such as CPU temperatures and voltages, perhaps fan speeds, in a visually pleasing representation. 

The couple of features at the bottom are worth noting.  The first is an option to adjust the page on entry, meaning that overclockers can go straight into the overclocking options menu when entering the BIOS rather than have to navigate through the Main menu.  The final option is a UEFI Guide option, which when selected will go through a quite slow text guide of the different features of the BIOS.  This is in part a nice idea for new users, though I believe the guide has to be more refined than this initial version.

Most enthusiasts are going to head on over to the OC Tweaker menu to adjust overclocking options.  ASRock have separated the overclock options under headings for a single menu, starting with automatic overclock options (4.0 GHz to 4.8 GHz in 200 MHz jumps), then CPU, DRAM, FIVR (Fully Integrated Voltage Regulator), and finally voltages.  We get separate menus for DRAM timings, which also comes with a memory tweaker for XMP settings.

In the Advanced Menu is where we get our enable/disable controller options, along with adjusting the SATA configuration for RAID setups.

The ASRock Tools menu is where we often find ASRock’s newest additions to the BIOS.  Every generation we seem to get something new – from the past we get the System Browser, the Online Management Guard, Dehumidifier function and Internet Flash.  New for this generation is the ‘UEFI Tech Service’, ‘EASY RAID Installer’ and ‘Easy Driver Installer’ options.

Starting with the System Browser, this is a top down pictorial representation of the motherboard, and the different items that are inserted into the motherboard before POST are shown here, such as the memory, what is detected in the PCIe slots, as well as SATA and Rear IO configurations.  This is particularly helpful if a user suddenly loses access to a GPU, memory stick or hard drive – if it is not detected in the System Browser, it will not be detected in the operating system.

Online Management Guard (OMG) is a simple attempt to disable network ports at various times of the day.  While easily circumnavigated by adjusting the BIOS time or manually disabling the option in the BIOS, the purpose behind this feature is to adjust when children are allowed to use the internet, or for businesses to disallow ‘casual browsing’ after hours.

The UEFI Tech Service option is designed to send problem reports to ASRock directly from the BIOS.  This feature only works if you have a wired Ethernet connection to the internet, and sends ASRock an email with the BIOS information used as well as a description provided by the user.  There is a similar feature in the OS software.

The Easy RAID installer helps users take the RAID driver off the driver disk and place it onto a USB stick for installation of a Windows OS onto a RAID array, and Internet Flash allows users to update the BIOS with the latest version from ASRock’s online servers without jumping into an OS.

Due to the 3-pin fan headers on board the fan controls are basic at best, found under the H/W Monitor section.  ASRock allows users to provide basic control or a series of pre-defined settings: Silent, Standard, Performance and Full Speed.

Elsewhere in the BIOS are Boot options and Windows 8 Fast Boot options.

    In my personal experience and from ASUS tech support, the safest way to update bios is by first downloading it. This mobo has an excellent update program in bios that only looks at local drives, not online. I found it quite simple at each bios update.

    Great job Ian, really looking forward to the super high end motherboard review as well! I'm curious though, did you use the VGA port at all in any of these reviews, and also when was the last time you used a VGA port?
  • IanCutress - Thursday, June 27, 2013 - link

    My Korean 1440p panels are all via DVI-D. But the VGA comes in use when you have to use a DVI-I to VGA converter for DVI-I cables. Otherwise you need a DVI-D cable.

    Great review Ian. I very much appreciate your taking the time to explain the PCIe slot assignment and repeating the less-than-x8-no-good-for-SLI truth that needs to spread far and wide.

    What I took away from this review when analysing my own usage patterns and component choices is that each of the boards in this review would be better suited to the mATX form factor. There is no point in purchasing these mid-high end boards for multi-GPU, multi-display configs. There are only a handful of full size z87 boards that in my opinion earn their full-size status.

    If it has fully integrated voltage regulators then why in blazes does it still need $20 worth of components buried beneath $3 heatsinks surrounding the cpu socket? Yeah, that's what I thought....
  • DanNeely - Thursday, June 27, 2013 - link

    What FIVR means to Intel isn't quite what you think it means. What's on package is the collection of VRs needed to provide power to all the separate sections of the CPU and to vary them as the chip clocks itself up and down. The motherboard itself still needs to do the heavy lifting to convert the 12V from the PSU to the voltage used by the DRAM and to a single input voltage the that CPU converts to the other levels it uses internally (IIRC this is the full load core voltage).

    I believe the reason why those regulators can be squeezed into the package while the ones still on the mobo are much larger is that the uncore/cache have relatively low power levels and the lower core voltages are only used at low CPU loads and thus don't need to push nearly as high of a peak current level.

    Wonderful review, Ian. Any chance of a Z87 vs Z77 vs ... comparison chart? It seems like functionalities of the processor are highly publicized, and the individual motherboard reviews chart the differences between chipset models within that family, but I don't recall seeing a comparison between chipset families. I know the chipset seems to be taking a smaller and smaller role these days, but it would still be helpful to exactly see the differences between generations.

    Thanks!

    The only downside for me is that it unfortunately does not work with Korean 1440p monitors (!), but Gigabyte is looking into this.


    It doesn't work with my 30" U3011 monitor either, yet another forum user with the same monitor didn't have any problem. Only difference was he used a Radeon and I use a GTX 480.

    I only had time so far to skim this article, so I apologize if this question was already answered in the body. Is there any way to find out when each board starts shipping with the C2 stepping of the Z87 chipset? As some people are already aware, the C1 stepping has been shown to have issues with certain USB 3.0 controllers disconnecting when the computer awakes from sleep mode. The C2 stepping is apparently already shipping to manufacturers, but it would be handy to know a way to ensure that a person who orders a board in the near future receives the updated chipset.
  • blackie333 - Friday, June 28, 2013 - link

    I'm not sure that C2 stepping shipping already started, according to public available plan from May only samples have been sent to manufacturers. Mass production of C2 should start on 1st of July and manufacturers should start receiving them from the 30th of July. Boards based on C2 stepping should be available for end users from middle August.
    But you maybe have some more actual/insider information.
