Gigabyte Z77X-UP4 TH BIOS

We have tackled Gigabyte’s 3D BIOS several times over the past few months.  It used to be slow and dim-witted, with slow transitions and a distinct lack of organization.  Since then, the Z77 BIOSes has been improved in terms of speed and feel, to something more-or-less useable.  There are still some niggles to contend with – no serious explanation of features, the 3D BIOS mode could be improved a whole lot, and overclocking options are still hap-hazard.  If our words are being considered by Gigabyte, then perhaps there an update soon would alleviate some of these issues.

Gigabyte still has a couple of issues that need greater attention though.  It seems hit and miss if a BIOS affects our DPC Latency test, which is a good indication of audio responsiveness – sometimes a Gigabyte BIOS, in combination with EasyTune6’s hardware monitor, will cause DPC latency to rise to 1000+ microseconds.  Typically a value below 200 is preferred, and it is fixed on some BIOSes and models, but it was not fixed for our testing.  One other point of contention is the manipulation of the reported voltages of the CPU from BIOS to OS.  Whenever a voltage was set manually in the BIOS, e.g. 1.200 volts, the software in the OS would read the save value no matter the setting at load – 1.068 volts.  This indicates that at some level the value is either not being passed to the OS or is being manipulated by the firmware.  This needs to be updated ASAP.

The BIOS system itself starts with the 3D BIOS mode, as shown below:

On the screen is an oblique angle image of a motherboard.  The actual layout of the motherboard in the image does not always reflect the motherboard in question – Gigabyte use a generic image per chipset and per motherboard size.  The important areas are those that are clickable, such as the CPU socket, the memory, the PCIe slots, the chipset, the SATA ports and the IO panel.  Each one offers a small selection of the full blown settings.  While this is useful from a ‘quick’ perspective, as I have mentioned on previous Gigabyte reviews, if I asked a family member who is not au fait with motherboard terminology to ‘go change the SATA settings in the BIOS’, they would not have a clue just looking at the image.  This leads to my previous suggestion of hover tool-tips when the mouse is over certain elements.

What irks me more is the lack of detailed information when we go into the BIOS.  Nothing indicates us to which motherboard is installed, which CPU is present, how much memory there is, temperatures, voltages or fan speeds.  Each of these is vital for a system builder or to diagnose faults. Instead we have to navigate to the advanced menu for this; however it should be available of the bat.

Also in this ‘3D BIOS’ mode, we get options to change the language of the BIOS, the boot order of the devices currently connected and the fan controls.  The fan controls have been a regular contentious issue, as Gigabyte only offer settings in terms of PWM values / °C rather than fan % or RPM values.  It should not be too hard to knock up some form of advanced fan control if you have access to temperatures, fan speeds, and can control the PWM values, however no thought was applied despite there being a wealth of potential.

The Advanced menu takes us into the hub of overclocking settings, designated M.I.T.  This section gives us menu options for CPU speed control, power calibration settings, memory settings and voltage settings.  Although from a navigation perspective, it is a clumsily laid out, with CPU speed, CPU voltage and CPU Load Line Calibration all being in different menu settings.  It would have been easier to group the important options into a separate new menu and still keep the old layout.  Despite this, we got very good manual overclocking results, hitting 4.8 GHz at 1.300 volts.

Options to enable and disable controllers are found in the Peripherals menu, including all options related to Thunderbolt.

    "Despite all this, Gigabyte’s foray into the Thunderbolt world is spurned in part by the board we are reviewing today...."

    You probably meant 'spurred,' though that doesn't really fit either.

    Also, the very first sentence should be more like "Because the exclusive license has expired...."

    Thanks for pointing the first one out - it should have been 'initiated in part'. As to the phrasing of the first sentence, I find it common enough where I am. Not sure if it's a UK thing or not, though US vs. UK idioms have been commented on in past reviews. As always, if anything catches your eye please feel free to email :)

    Speaking of UK vs US, I had to Google your Stella Artois reference, and I actually drink the stuff occasionally. Must have been a UK specific ad campaign.

    I understand that Thunderbolt is a lot faster and a different usage than USB 3. Frankly, it's not so much better than USB 3 that consumers will pay for Thunderbolt. USB 3 is already leading, and Thunderbolt will be left behind like Firewire despite the tech being superior...

    It's rather meh on desktops since it's pretty easy to add new hardware internally, but it makes far more sense on laptops when you have limited number of ports. Having an external PCI-Express bus is interested, especially if external GPUs ever actually arrive at an affordable price point.

    If you're going to plug in one device, yes. I think the strength of Thunderbolt is as a laptop dock - plug in one cable and you got wired network, sound, keyboard, mouse, printers external screens, any USB 1/2/3.0 device, firewire, esata, external graphics card dock, regular 3.5" HDDs and whatnot. That can have a future in many companies I think who've now chosen laptops for higher flexibility - now you can have that and dock into a full system with one cable.

    It will mean a lot if they ever put thunderbolt on a mini itx board. I know a lot of SFF enthusiasts who would love to try external graphics with a sub 10 liter enclosure. But on a full size ATX board it doesn't really mean a whole lot.
  • Skidmarks - Tuesday, September 18, 2012 - link

    That's possibly true but only time will tell.

    It really would've been nice to see some Thunderbolt testing. I realize Anand is hogging all of the shiny TB gear, but the review didn't really test the primary draw of this MB and as such is kind of useless.
  • zanon - Monday, September 17, 2012 - link

    Agreed. As the summary correctly states, the raison d'etre of this board are the TB ports. Even if it's just the overpriced Promise a review should give them some stress and see how they perform. Maybe it'll get easier if QNAP ever releases their JBOD.
