Since I started writing for AnandTech, back with an initial X58 review and from P67 onwards, the graphical BIOS paradigm has been shifting. Motherboard manufacturers are becoming more efficient in packaging their BIOS into a small 64 Mbit or 128 Mbit package, including enough drivers and extra features (sounds, images) to make the graphical experience for the user better. This should include efficiency tweaks, so we are scrolling at something above 30 Hz, but also some manufacturers have been playing around with higher resolutions, as well as fonts that are easier on the eye than Courier. ASUS falls into this crowd, and its new BIOS expands the fan controls into an easier user experience. However I feel there has been a slight regression in the tabbing interface.

The BIOS receives the same brushed look as the motherboard heatsinks, and while it cannot be metallic, there is a distinct contrast between the color of the background and the text such that users can identify what is written as well as what is selected.

The first screen is the ‘EZ Mode’ which gives info on the system: the motherboard, the BIOS, the CPU used, the PCU speed, the memory DIMMs installed, the capacity of the memory, the speed of the memory, the CPU temperature, the CPU voltage, the motherboard temperature, the fan speeds and the CPU fan gradient graph. Users can enable XMP from this menu, as well as select the boot priority and quick tuning profiles for the system. A cool new addition is the fan profiling, direct from the easy mode. The fan speeds on the left show a fan spinning, and the faster a fan spins, the faster the animation. But click on the button marked ‘Manual Fan Tuning’ and after a quick test of the system fans, the following menu appears:

Users can select each of the five controllable fan headers (the sixth is for liquid coolers that want 100% pump operation) in either PWM or DC mode. Each fan can be referenced to one of the four preset options (standard, silent, turbo, full speed) or users can go manually and adjust a three point gradient. Ideally I would prefer more points in the gradient and a hysteresis option here in the BIOS as well, but we will look forward to any future adjustments.

Also part of the Easy Mode is the Tuning Wizard. This is a button up the top, above the CPU Temperature. Selecting it gives the following screen:

On previous ASUS motherboards I had lamented the lack of variable overclock options. It was often just ‘Tuner’, or a choice between ‘Fast’ and ‘Extreme’. ASUS took this onboard from several sources and developed this interface, allowing users to select what they do with their PC:

What sort of cooling is being used:

And then the BIOS gives an estimate of possible overclocks when the Tuning Wizard is implemented:

So in this case, the BIOS is predicting (based on internal testing and a lookup table) a 28% increase in CPU speed (3.5 GHz to 4.5 GHz) and a 84% boost in DRAM speed (1333 MHz to 2450 MHz) when we had an i7-4770K equipped with 32GB of Corsair DDR3-2400 C10. At present the BIOS is not that smart, so if the overclock fails the user will have to get into BIOS and set defaults if their CPU cannot take the speed and voltage. Because Haswell is so varied in its performance (e.g. I have a CPU that fails 4.3 GHz at 1.35 volts), ASUS has to draw the line between aggressiveness on auto overclocking against the likelihood that some CPUs are bad overclockers. If an overclock fails, try retaking the tuning and selecting the lower cooling option; this will cause the temperature limits in the OC to adjust to hopefully accept an overclock on a poor processor.

Astute readers will notice that Easy Tuning also has a RAID function. Part of the feedback ASUS has received from the 8-series is the ability to build RAID drives using hardware drivers. This tool is designed to take control of the Intel RAID interface, and users can build arrays through the BIOS instead. I want to take this feature for a spin, but I will leave that for another ASUS review.

Moving into Advanced mode also affords an adjustment from Z87. ASUS is being more economical with the space, and the use of a different font makes it more readable with no need to put significant gaps between each row of text. As a result, we get a Hardware Monitor on the right hand side with all the poignant information about the CPU, DRAM and Voltage. I would have liked the motherboard name and BIOS version in there as well, just to complete the set. At the bottom is the help menu. Moving it to a longer horizontal side allows more text on the same line and less strain on users who read about controls to keep adjusting their eye line. That might sound like hooey, but I see it as a good way to use space.

ASUS has definitely regressed in a couple aspects in the design however. It is quite hard to explain in text without a video, but it all comes down to the spacing of the tabs and buttons at the top.

When we use a tabbed web browser with multiple tabs, each tab gets its own section in the tabs area. Each of these tabs is a fixed width, no matter how long the text is. The same with icons, these are a fixed size no matter what the icon contains. When we click on a tab, a whole new window appears with new information, or in the case of Chrome, it is a new OS process. With bookmarks however, these are of variable length up to a maximum. In the Chrome bookmark bar, both folders and individual links are variable in length, because you are in the same process or creating a dropdown.

With that in mind, look at the ASUS BIOS. The list at the top, starting with the date, time, ‘English’, ‘MyFavorite(F3)’, ‘Qfan Control(F6)’ are all of variable length. The list of tabs underneath this, ‘My Favorites’, ‘Main’, ‘AI Tweaker’ are also of variable length. The downside of having it done this way means that if a user wants to click on an option, there is no chance of ‘guessing’ where the right option is due to the variable length nature.

Perhaps I am being a little sensitive here. I can imagine that it might not affect a significant number of people. However in the back of my mind, it might improve the user experience. Other manufacturers have used icons with embedded text to represent these menus, such as a spanner for ‘Tools’ or a temperature meter for ‘Monitor’, which with the right icons/images might be a preferred option if there is space. Because we are dealing with higher resolutions and better image fidelity in the graphical BIOSes, I cannot imagine that static images would affect the redraw rate much, especially compared to the new side-swipe animation ASUS has enabled between selecting these tabs.

With the side-swipe, like on a mobile device the text follows the swipe, and in the ASUS BIOS the side-swipe has to complete before the text is selectable the page. Unfortunately the side-swipe is not as smooth as a mobile device because of limitations, and it takes a good 10-15 frames to complete, or 0.3-0.5 seconds. This might frustrate some users who want to access certain features quickly. The system does allow double tabs to skip tabs, but the side swipe still has to finish before options can be selected, giving a small amount of lag.  Thankfully there is an option to disable this, under Tools called 'Setup Animator'.

The purist/pedant that I am aside, there are still some new and updated features in the BIOS that work well. The My Favorites menu has adjusted so users access a setup map (like a sitemap) in order to select the options for My Favorites:

With the color scheme and font, this is actually really easy to use. Previously users had to navigate to each option and press F4/right click to add to my Favorites, but this condenses that selection into a single menu speeding up the process. The options that I usually use for overclocking my home systems are selected in the screenshot above, which when we navigate to My Favorites gives:

It should be noted that in order for an option to be selectable on the Setup Tree Map, it has to be visible in the BIOS.  This means that if you want to change the CPU fixed voltage, the option has to be set to 'Manual Voltage' before the option appears to set it in the Tree Map.  This is a little annoying, particularly if you are in the My Favorites menu already and decide to add options - as the menu does not refresh, you have to access another tab and navigate back.  At this point it might be worth ASUS' in house overclockers to offer their own My Favorite presets for enthusiasts to use.

For the settings that involve voltages or specific values (such as CAS Latency), the BIOS gives in indication of the current value, whereas the help section at the bottom will display the range and granularity of the setting.

The full overclocking options are in AI Tweaker, and these follow the previous BIOS iteration starting with frequency settings, with sub-menus for DRAM timing and DIGI Power, and then voltage settings. As mentioned the Board Overview, for extreme users wanting to use sub-zero cooling, the OV_CPU jumper on the motherboard has to be enabled to allow extreme voltages:

Load line calibration and switching frequency options are in the DIGI+ Power Control sub-menu, whereas power limits are in CPU Power Management.

Because of the use of switches to enable/disable certain features when others are in use, it pays to understand certain options in the Advanced tab. The usual options are all here, such as HyperThreading in the CPU Configuration menu:

RST/SRT in the PCH Configuration menus:

Display choices in the System Agent Configuration menu:

Out of the two most important menus in Advanced, the PCH Storage allows users to force select between the chipset SATA Express port and the M.2 slot:

Whereas the Onboard Devices menu will allow users to force select between x4 on the final PCIe slot for dual Thunderbolt 2 card, x2 on the final slot for two of the USB 3.0 ports on the back, or Disabled to use the second SATA Express port.

The Monitor tab contains the onboard sensors, as well as the option for Q-Fan Tuning. This tuning needs to take place before using the custom graph adjustments in the Easy Menu, but the easy menu will direct users here automatically. In this menu however users can tie each of the fan headers to a specific sensor on the motherboard, including the T_SENSOR if a user wants to use their own thermocouple.

The Boot tab contains the fast boot options, the boot order and also the boot override features:

To update the BIOS, ASUS still has the EZ Flash 2 tool in the Tools tab:

The Tools tab also contains options for saving overclocking profiles and viewing DRAM SPD information. Because of the ability for ASUS to adjust font sizes in this new BIOS revision, even though the SPD info page has to use the Courier font due to the amount of information, we can get it all on one screen:

Carrying over from the last generation of BIOSes is also Quick Note and Last Modified. Quick Note is essentially a small note pad to write notes about the BIOS, and Last Modified indicates which settings in the BIOS have changed since the system booted:

    Lovely tongue-twisting title.
  • LancerVI - Friday, May 16, 2014 - link

    Nice board here, as usual, from Asus. I must say though, being a shallow man, that I would love to see and end to this gold design scheme and a return of my beloved blue.

    Please, for the love of all that is holy; Asus, return the blue scheme.
  • LancerVI - Friday, May 16, 2014 - link

    *an end

    Also or all black
  • Antronman - Friday, May 16, 2014 - link

    The blue scheme was ugly, and far too bright. It was also a very cold color.

    I like this new dull, bronzed gold like on the TUF series, because it's a lot more neutral. You can make any color build you want with it.
  • LancerVI - Friday, May 16, 2014 - link

    If you want neutral, all black would be truly neutral. Gold is just terrible.
  • pixelstuff - Friday, May 16, 2014 - link

    I was thinking this was one of the classiest looking color schemes they've ever made.
  • Challenge - Monday, May 19, 2014 - link

    Artistically the color choices are perfect and conform with the principles of color choice.
  • superflex - Wednesday, May 21, 2014 - link

    The 90's called. They want their brass and glass coffee table back.
  • Flunk - Friday, May 16, 2014 - link

    Do you know what we really need from the next generation of Intel processor/chipset? More PCI-E lanes.
  • SirKnobsworth - Friday, May 16, 2014 - link

    Rumor has it that the chipsets accompanying Skylake will have 20 PCIe 3.0 lanes, as well as an upgrades DMI 3.0 path to the CPU. As we can already tell, they will be sorely needed.
