Gigabyte Z77X-UP7 BIOS

When a motherboard manufacturer develops a range of products, most of who I am expects to see some form of product segmentation when it comes to interaction with the motherboard beyond hardware. With the ASUS ROG range and Fatal1ty by ASRock, our BIOS and software both get new skins, even if there is not anything fundamentally different in the software itself. Both ASUS and ASRock have the benefits of easy and understandable systems to work with, but in the past Gigabyte has not had the luxury. Perhaps this is partly why the Z77X-UP7 BIOS (and software) uses the same old systems we have reviewed before – there is more worth in diversifying something good than partitioning out the average, especially when the competition is highly competitive.

So for the Gigabyte Z77X-UP7, our mainstay in the BIOS is the ‘3D BIOS’ representation. In previous reviews we have labeled this as near to a mild gimmick as you can get – an oblique image of Generic Motherboard #234, with various parts of the board that can be highlighted. If the user has no knowledge of what a motherboard looks like, this means nothing, as there are no tool-tip popups when the SATA or PCIe are selected, or any indication of what a BIOS is for. We have no indication of what motherboard is actually being used, what BIOS revision is installed, what CPU is installed, how much memory is installed, or any vital temperature/voltage/fan values. While I understand the split between using the BIOS as a marketing tool for the system (as most vendors do) compared to using the BIOS as a marketing tool for the motherboard (Gigabyte), this is an odd and frankly bad way of going about it. I cannot tell a family member down the phone to select the memory slots for XMP if they do not know what memory slots look like and there is nothing to guide them there. I impatiently wait for an updated version of this front screen geared towards a more user friendly experience and full of informative data on the system.

Rants aside, functionality wise each part of the motherboard does display a few options. The CPU options involve frequency and voltage adjustments with a section for memory, the SATA options allow changing of the controller mode (AHCI as default, but also IDE and RAID), and the rear IO deals with enabling/disabling controllers along with USB functionality. The power delivery sub-menu offers phase control, as well as various voltage, current and thermal options. Most of these sub-menus are merely the same as their ‘advanced’ menu counterparts but with sliders where appropriate.

In this front screen we also get icons on the bottom to adjust the boot order, the language of the BIOS, and our basic fan controls. Over the past couple of years the Gigabyte fan controls have spanned a small range from a confusing mash of odd value assignments to basic gradient application. Despite the numerate fan headers on board, only the 4-pin ones are controllable, and Gigabyte will give you access to that gradient in odd units known as PWM value/°C.

For the non-engineers, the higher the number of this option will result in the fans receiving more power at lower CPU temperatures (i.e. a more aggressive fan control). This is despite the fact that a fan speed profile is never linear, shown by my CPU fan:

Below 5% power, my fan is essentially off. From 5-20%, the fan spins at 800 RPM regardless of how much power is applied. Above this the RPM to Power ratio is fairly constant. What motherboard manufacturers should be doing (ASUS do this in software, Biostar do it in the BIOS) is giving an option for a fan test, polling this data, and then adjusting the fan profiles via software to match. A common response is that ‘it’s more complex than you think’ or ‘it’s too complex’ – when dealing with two inputs (CPU temperature, fan speed) and one output (power applied), writing black box software to connect them in various ways should be a stroll in the park for any trained programmer.

Second rant aside, the bulk of the BIOS is actually a lot more readable in the Advanced menu (icon on the bottom left). Opening this takes us straight into the M.I.T. (Motherboard Intelligent Tweaker) tab, which offers some of the information we should have had before – BIOS version, CPU temperature, VCore. It is still missing the words ‘Gigabyte Z77X-UP7’ and ‘i7-3770K installed’ however.

The MIT tab gives sub menus for a current status screen, frequency settings, memory settings, voltage settings, PC Health (i.e. fans) and a couple of other miscellaneous options. The frequency settings menu is where most overclockers will head, and the basic options to adjust multiplier, base clock and memory are here, with power options in a sub-menu off of this one. What are not here are the voltage options. I had a brief argument with HiCookie, Gigabyte’s in-house overclocker, the last time I met him about why this is the case. Personally, when overclocking the CPU, I want all my CPU options in a single menu – multiplier, BCLK, power options, voltages and temperature readings. In HiCookie’s experience, he wants everything in separate menus – when he wants to change a voltage, he wants a menu with all the voltage options. I can see how doing it that way may help such that users do not accidentally pump 2.0 volts through their new CPU, but the only users in this menu would be the enthusiasts. Perhaps we can have both - keep the separate menus for 3D BIOS mode, and give me one page for the CPU options including voltages and temperature sensors, and another for memory settings too.

The 3D Power options are fairly substantial, allowing the user to adjust thermal protection limits, switching rates, over current protection and over voltage protection. However it still seems odd that Gigabyte have split almost everything into separate menus. For example, when dealing with just the voltages, the CPU options and memory options are in separate menus. Doubly worrying is that although Gigabyte has left a space on the top right as a description box for the option selected, the descriptions are short or either non-existent.

The fan options are in the MIT->PC Health menu, where we get most of the sensor readings – some voltages, onboard temperatures and fan speeds. By default all the warnings the board can provide (fan fails and CPU temperatures) are disabled, and our fan options are just as limited as in 3D BIOS mode.

Oddly enough Gigabyte does not allow direct control over the PCIe lane allocation. In most high-end motherboards, we are able to select individually which of the PCIe slots are to be PCIe 3.0 enabled, and drop them down to PCIe 2.0/1.1 if compatibility is an issue. On the Z77X-UP7, we only get a single option to control all PCIe slots – ‘PEG Gen3 Slot Configuration’, in the MIT->Miscellaneous menu.

Other options in the BIOS are as regular as any other system – boot order, controller functionality, Smart Connect Technology, Rapid Start Technology and SATA modes. The UP7 also has a segment in the BIOS features menu for Windows 8 quick POSTing, under CSM Support. Ideally this should be wrapped up into an easier set of options to make it easier to understand – not everyone knows that under Windows 8 these should be adjusted for those quick POST times. A final positive note is that Gigabyte includes Boot Override, an option for a single time boot from a specified device – very handy when installing an OS via USB.

    You're not going to find what you want in a 7-slot ATX form factor. However, dropping down your x16 GPU requirement makes possible with water cooling and a good X79 motherboard.

    Moving up to Xeon opens up some more options. One is this: Real PCIe 3.0 x16 Quad-SLI, plus two more PCIe 3.0 x8 and one PCIe 2.0 x4.

    Getting those last PCIe lanes is very, very expensive, and completely worthless for anything but GPU compute.

    I'm hoping for a few new motherboards with the next enthusiast platform refresh. Ideally 10 slot to make room for all the expansion cards a gamer geek could possibly use :D
  • Samus - Friday, March 1, 2013 - link

    Can you use all 5 pcie x16 slots simultaneously with single-slot GPU's, obviously not in SLI?
  • Samus - Friday, March 1, 2013 - link

    You answered my question above, thanks!

    You said:
    If Gigabyte was going for more sales, from my perspective, if some of the IR3550s were removed and the system reduced to just over $300, it might get more takers

    What Gigabyte does have on the market is the">UP5-TH for about $250.

    It have the exact same PWM chip in the VRM as the UP7 (8 phase IR3563), only that UP7 runs it through a quadrupler for 32 VRM phase while UP5 don't use any so it runs only 8 IR3550 but 8*60= 480A is already overkill for Ivy Bridge.

    The only other thing UP5-TH misses other than VRM phase overkill is the PLX chip, so it can't run 4 way SLI/CLX, and can only run 3 way at 8X/4X/4X. But for people running 2 cards or less it is more than enough.

    UP7 is a halo product/ultra flagship just like the GTX Titan, UP-5TH is the mainstream Flagship.

    Yup, we reviewed the UP4 TH:
    Though that goes along their Thunderbolt line. The Thunderbolt controller isn't cheap. But as mentioned the comparison is the G1.Sniper 3 with the PLX, or the Z77X-UD5H without the PLX (or Thunderbolt).

    Y U no use WinRAR 4.2 ?

    Its much better multithreaded.
  • IanCutress - Friday, March 1, 2013 - link

    To maintain consistency with the last 18 months of benchmark results ;) Should probably do an update for Haswell later this year though.

  • Kevin G - Friday, March 1, 2013 - link

    For a user putting down $400 for a motherboard, especially one aimed at overclocking and high performance, why not go the LGA 2011 route and X79? In this price range, LGA-1155 and Z77 just don't seem to be premium products in comparison.
  • baberpervez - Friday, March 1, 2013 - link

    Why in the world is Gigabyte focusing on the LG1366 market? With all new cpus being LG1155 or 2011, seems counterproductive to produce a unit for an older motherboard kind. Even with my I7 960 I don' tknow why anyone would want to upgrade to this product. With triple -SLI (570s) a fourth slot is useless since the cards are only 3 way capable, but definitely worth experiementing on for 480's/580s/680s.

    The price is what it is, very hefty...and only serious overclockers would want to purchase this.

    If Nvidia made the 570 quad sli than I would consider getting this, but there's no chance of me replacing three cards to go into a higher configuration anytime soon.

    This board would have done very well a few years ago...
    Just not convinced LG1366 was a good idea.
