The nature of living beings is to adapt to the surroundings around them – if it is cold, we put on warm clothes, and when it is wet, we tend to seek shelter.  When it comes to technology and electronic products, the same can not be said.  Innovation is driven by competition, otherwise product lines stagnate. If there was a technological elixir to end all competition, that would be it.  By now you are probably wondering what this has to do, if anything, with the BIOS for a motherboard.

Adaptation of the BIOS in the past couple of years has been driven by competition.  Before graphical interfaces for the BIOS became the norm, we were greeted with white text on blue screens, or white on black.  Now we have a vast array of graphical options at our disposal, and each company is trying to outdo the other.

Initially two companies had the upper hand – both ASUS and ASRock had systems to use multiple colors and mouse movement, making BIOS navigation more intuitive.  MSI went a different route and included games in their BIOS as part of a technical exercise to see what was possible.  Gigabyte sat back and kept with the old style BIOS.  At the time, that meant they were not on the crest of that innovation wave, but I am told by Gigabyte that the reason was due to development of their own BIOS system rather than reskinning an AMI or Phoenix BIOS base code like the other manufacturers.  When X79 motherboards were released, Gigabyte showed us the fruit of their endeavors, which ended up being an adapted AMI BIOS rather than a complete rewrite.  I was not impressed.

The initial release was slow, bulky, and along with many other reviewers, was baffled by the naming system.  Gigabyte called it their ‘3D BIOS Technology’, using 3D to mean 3-dimensional. The majority of users would have been exposed to a 3D environment on their computers, either through games or design.  But Gigabyte had construed this terminology to apply to images drawn at an oblique angle.  There was noting three-dimensional about it – the user could not navigate from foreground to background (anyone remember playing Tombi/Tomba on PSX?).  All we had was an oblique image with clickable parts that gave smaller versions of the advanced BIOS functionality.  This 3D BIOS aside, due to the slow and young BIOS which had not had time to develop, we struggled to deal with odd decisions regarding menu allocation (overclocking voltages were several clicks away from the CPU speed adjustment) or fan control terminology.  At the time, and since, I made a raft of criticisms and suggestions.

Fast forward almost a year and several things have changed for the better.  We can now navigate the Gigabyte BIOS at speed, which is most important.  Boot times on certain models can be aggressive, and Gigabyte is opening up more options in the BIOS than before.  I love the fact that we can screenshot the BIOS rather than having to photograph the screen (despite some reviewers still miss this feature and get the camera out).  We are still stuck with this 3D terminology though, and some odd fan terminology.  I have explained to Gigabyte that normal users do not work in PWM values / °C, so I am hoping that will change in the future.

Gigabyte H77N-WiFi BIOS

For the H77N-WiFi explicitly, the first odd feature to point out should be the ‘3D’ image used at the front head of the BIOS.  Despite the disclaimer that ‘the above photo is for reference only’ we would expect the motherboard to resemble somewhat like the board at hand.  For the H77N-WiFi though, we get an image of a micro-ATX board, with the chipset and socket area in different places.  Is it that time consuming to put in a mITX image?  I fear that this was just an oversight with this BIOS version and should be corrected in the future.

My usual gripes with BIOSes are going to be expressed again, because very few manufacturers seem to take these hints on board (maybe I am not shouting loud enough).  Nowhere on this front screen does it tell the user (or system builder, debugger) at least the two main things that should be present on the front screen of ALL BIOSes – the model of the motherboard and the CPU present.  This information should be in the face of the user when we enter the BIOS so mistakes are not made with the system we are working with.  Alongside this I would also want the current speed of the processor, memory installed (along with module size and memory speed), CPU temperature, chipset temperature, important voltages and fan speeds.  If we count the first two requests as the primary detail and the others as secondary detail, what is to stop the primary details being shown on the front screen and the secondary details being shown in a pull out menu when the mouse drifts to the side or corner (like in Windows 8).  This is a graphical BIOS – a metaphorical playground to make the experience of owning the product come to life and exciting.  I see very few motherboard manufacturers taking advantage of this to the full.

Despite this, the functionality of the H77N-WiFi BIOS is as follows.  The main screen gives an image of a generic BIOS of which various areas of the motherboard can be highlighted and clicked, such as the CPU, the memory, the chipset, the SATA ports, the IO panel and so on.  When clicked, each area will bring up a limited set of options pertaining to that motherboard section – the rear panel section for example will give options to enable/disable audio and LAN ports as well as USB legacy support.  Also available are options to adjust the boot order, change the language, or deal with fan controls.  It would be ideal if the areas on the motherboard, when highlighted, gave a small indication of what they are – asking a family member to ‘select the SATA ports’ on the BIOS over the phone is a bit useless if they do not know what a SATA port is.  These are small little adjustments that could be made to make the experience smoother.

The bulk of the options are found in the Advanced menu.  This opens up into a typical modern day graphical BIOS interface where we have the main options along the top, with options and sub-menus in the main area.  The first advanced screen is the ’MIT’ (Motherboard Intelligent Tweaker), where we actually get some details regarding what is onboard – off the bat we have the BIOS version, CPU Frequency, Memory Size and frequency, CPU temperature and some voltages.  All that information (along with the motherboard model more importantly) should be in the 3D menu previous.

Various sub-menus can be spawned from the MIT menu.  We can select ‘Current Status’ to give a more detailed rundown of the CPU and memory; the frequency settings which can adjust the speed of the processor (only below the rated speed on an H77 by multiplier but BCLK can be adjusted up), memory (max 1600 MHz) and IGP.  We also have the advanced memory settings sub-menu where XMP and sub-timing adjustments can be made.  The advanced voltage settings offer only the memory voltage to adjust, so do note that the H77N-WiFi does not allow down-clocking. Finally the ‘PC Health’ sub-menu which gives voltages, temperatures, fan speeds, and the fan speed control which gives options in PWM values / °C.

An important menu to consider is the final sub-menu ‘Miscellaneous’ settings.  Here we have two options – one for legacy benchmark enhancement (an odd option to include for overclockers on a non-overclocking motherboard) and the other to adjust the PCIe slot bandwidth.  When the system was left on auto, I had trouble getting any of my graphics cards to run at the full 16x lanes – I initially thought it was some clever down clocking, but it never seemed to come back up and use the full 16 lanes at PCIe 3.0 for a 7970 for example.  By navigating to this menu and adjusting the option to Gen3, the graphics sub-system never faulted and we got accurate benchmark results.  If this is a BIOS issue rather than individual issues, I hope it is fixed after F2.

Elsewhere in the BIOS is our standard array of BIOS Features (Boot options, Logo on Boot), Peripherals (to enable controllers, change SATA mode), and boot override system.

    I like the placement of the 24 pin power header. My E350 case has the external power button right where it interferes with the power header toward inside of front panel. Also I like testing with i3. I go for lowest power consumption. I use a picoPSU and would like to see these tested with that psu. For me it is a USB world. all I care about is HDTV, low power and USB3. If you want to overclock perhaps you should go with a bigger board.

    Why don't anybody makes a z77/h77 board with dual link dvi output? Is it so much more to make one?
  • Dug - Friday, November 9, 2012 - link

    Good question, and it would be nice to know the limitations of video output on these motherboards with different connections.
  • Znarkus - Thursday, November 8, 2012 - link

    Why present POST time with two decimal points, if there is a 1 second error margin?
  • IanCutress - Friday, December 7, 2012 - link

    Results from my stop watch. Error margin is a large overestimate of what it might be from human error, not hardware error. For each reading I take 3 measurements, and more often than not I get all three in the same 0.10 seconds.

    I would love to know how well this is supported under Linux? No real need for Benchmarks just put Ubuntu, Mint, or Fedora on it and see if the Network, WiFi, Video, Sata, and USB all work.
    Also Hackintosh compatibility would be nice but maybe too out their to be worth your time but would be very cool.

    The spec table shows z77 chipset, should be h77?
  • dingetje - Wednesday, November 21, 2012 - link

    please include the EVGA Z77 Stinger Mini-ITX Motherboard in the upcoming article.
  • lemmo - Tuesday, February 26, 2013 - link

    Thanks for the detailed review. Could you give an idea of what the audio benchmark actually means? Do those results indicate that the audio quality is good or bad?

    A review of the Gigabyte B75 ITX board shows that the audio quality is poor, and the Gigabyte Z77 board not much better. They also use Rightmark Audio Analyser, but represent the results differently so there is no way to compare. Please can you give your audio test results in dB(A) so we can compare?

    It would also be good to have a wider comparison of the power draw, say with the Z77 ITX boards you reviewed.

    have problems with the graphics card!! Works fine with the graphics BIOS settings at auto but does not work with BIOS settings with graphics set to PEG and changed the miscellaneous settings from Auto to Gen1,Gen3 but still didnt work. Tested it on different systems and it seems to work fine but does not work only on this mobo, the mobo itself is fine again. The graphics card is a HD6670 1GB DDR5.
