Gigabyte GA-Z77X-UD3H - In The Box

Over the past several motherboard generations, I have not been that impressed with Gigabyte's offering in terms of extras - this is because in order to hit a price point, sometimes the extras in the box are not the focus of the product.  With the Z77X-UD3H, we are hoping for at least some good stuff here.

Driver CD
User Manual
IO Shield
Four SATA Cables
One long SLI bridge

 

Voltage Readings

 

Using OCCT we monitor the voltage change of the motherboard under load.  This represents the direct correlation between the Load Line Calibration and how the processor/motherboard deals with voltage requests while under load.  This is not to be confused with the quality of power delivery, but more an indication of how aggressive the default LLC settings are on a motherboard.

The response of the Gigabyte board under load is fantastic.  No ripple at all and a lower average voltage than the ASUS P8P77-V Pro.

Overclocking

Note: Ivy Bridge does not overclock like Sandy Bridge.  For a detailed report on the effect of voltage on Ivy Bridge (and thus temperatures and power draw), please read Undervolting and Overclocking on Ivy Bridge.

The Gigabyte GA-Z77X-UD3H has a variety of overclocking tools at the disposal of the user.  Automatic overclocks are through EasyTune6, where we experienced a rather good result with our chip with Gigabyte's auto tuning software, and manual overclocks are either performed through the BIOS (with a series of menu jumps which should have been more carefully laid out), or using a new Gigabyte tool called TweakLauncher.  I have not previewed TweakLauncher here, as it is primarily for sub-zero overclockers wanting real-time access to changes in performance while under extreme temperatures.  It forgoes the usual GUI interface and sliders with something more amenable to the competitive overclocker - it is not suitable for the majority of users.

Auto Overclock: Using the Auto Tuning option in EasyTune6, the software pulled up a large screen and offered a confirmation of a stress-tested overclock.  When clicked yes, the system would stability test a range of BCLK and Multipliers until the board resets or the system finds it unstable.  When this had finished, the board offered me a 46x104.5 overclock (4810 MHz).  I discovered that turbo modes still applied, so this speed was the single thread speed, and the CPU would reduce the multiplier by two for multithreaded loads, giving 4589 MHz).  This gave 1.236 volts at load, which could be a little high, but due to the lower speed under multithreaded load, the CPU only reached 84ºC under PovRay and was completely stable.  I enjoyed this result a lot from an automatic overclock!

Manual Overclock: Due to the way Ivy Bridge behaves with increased voltage, for a manual overclock, I am testing the peak overclock at a variety of voltages as well as the temperatures at that voltage.  On the Gigabyte board, the CPU load line calibration was set to Extreme and Intel Speed Step was disabled.  One interesting thing to note was that Gigabyte set this board to 100.9 MHz default on the BCLK, rather than 100.0 MHz.  When the multiplier is pushed above 44x, this is reduced to 100.0 MHz.

At 1.100 volts, the highest multiplier that was stable was 45x, giving 4.5 GHz.  This gave 70ºC at load with PovRay, and showed a load voltage of 1.116 volts.

At 1.150 volts, the highest multiplier that was stable was 46x, giving 4.6 GHz.  This gave 75ºC at load with PovRay, and showed a load voltage of 1.164 volts.

At 1.200 volts, the highest multiplier that was stable was 47x, giving 4.7 GHz.  This gave 82ºC with PovRay, 86ºC with OCCT, and a load voltage of 1.212 volts.

At 1.250 volts, the board successfully booted at 4.8 GHz, with 1.272 volts under load and 89ºC with PovRay - but this was not stable due to the memory errors in PovRay, suggesting more voltage is required.  Given the current load temperature, I was unwilling to push the voltage further.

In terms of memory, when attempting to overclock a G.Skill 2x4 DDR3-2666 kit, which performed 2950 MHz on the ASUS P8Z77-V Pro, it would not boot at the DDR3-2800 strap despite all the correct timings being entered.

    Are Q connectors proprietary of ASUS? I seem to find those only their motherboards. Love them to death.

    Great review. I enjoy these tremendously. Almost makes me go out and upgrade my i5 2500k.

    My MSI P67A-GD55 has the same thing, unfortunately the connector block is too tall and bumps into my second 6950 so I couldn't use it. Reply

    I, too, am a fan of the Q Connector mostly for the front panel connections (power, reset, HDD light). The USB and audio connectors seem to be pretty well standardized at this point, rendering those Q Connectors redundant IMO. This would seem to be a very simple and inexpensive feature for a mobo manufacturer to have (at least for the front panel connector). Reply

    Thank you for including this important benchmark. I hope that every motherboard review going forward will include this.

    The ASRock has the best time but 8 seconds is still too long. I wonder why BIOS developers can't get their act together and initialize hardware in parallel. That would surely speed POST times up tremendously.

    I've been struggling about that issue myself. I mean - it probably was in times of BIOS, but now, with all fancy UEFI is it really that hard? (considering more resources spent on bios/uefi in mobo)

    Altough I'm not big fan of 200$+ motherboards, I would seriously consider buying one if it POST in 2s.
    Even though there are probably POST requirements such as cpu cant be tested before ram or opposite it would be awesome to have really low boot times.
    Sad when even having SSD cant give You instant full boot (not hibernations/sleeps).

    It's one of those small features that are soo awesome (like reset/power buttons, and perhaps, in future : complete per component (ram/disk/SB/NB/coolers) power usage).

    Nevertheless 8seconds is damn nice.

    Does anyone know how enabling AHCI in the UEFI affect post time these days? I'd like to remove the other 7-10 seconds this adds to it. Reply

    How do those Chromebooks shave time off of the POST? Seems like similar techniques could be implemented unless there is a good reason not to. Reply

    Chromebooks use OpenBIOS IIRC. OpenBIOS is Linux Kernel based and boots very fast because it initializes things quicker and it's custom built to the hardware on the board. Personally I wish all the Boards would start using it and toss these BIOS down the hole of history. Reply

    They've got a very stripped down set of hardware to initialize. The more stuff you have on board, the longer it takes. EFI was supposed to fix this by allowing multi-threaded boot (BIOS was strictly a single threaded design); but either firmware makers aren't generally taking advantage of it yet, or dependencies in the startup process are limiting the gains.

    Don't forget the graphics card (if using discrete) will need to support UEFI (GOP) Booting too! Reply
