Gigabyte Z77-HD4 In The Box

Motherboards on the low end of the price scale have only one focus – the motherboard itself.  While the $180-$400 packages might have those extras and bonus, we would not expect a $120 motherboard to produce much.  That being said, in the past we have been pleasantly surprised in $140-$160 packages, either ATX or mITX, which have included a USB 3.0 panel in the past.  That was when USB 3.0 was ‘an extra’, rather than a standard of the chipset – meaning that we are unlikely to get one of those as most cases now have a connector.  But in the Gigabyte Z77-HD4, we do get:

Rear IO Shield
Driver Disk
Four SATA Cables

I am surprised we have four SATA cables in the box – previous motherboards from Gigabyte have had two, so users wishing to have the additional storage have some extra headroom (as long as you are not blocking the SATA ports with a second GPU).

Gigabyte Z77-HD4 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.

Experience with Gigabyte Z77-HD4

To be honest, when dealing with a motherboard at a low price point, I was not sure what to expect regarding the overclocking.  A lot of the marketing fluff around the big launches and the high-end products is all about power delivery and overclocking prowess.  If the hullaballoo surrounding overclocking capabilities of the more expensive motherboards was blown away by smaller models, it just represents another angle that should prioritize feature set over overclocking.  Alternatively if a cheaper model falters, then the marketing surrounding overclocking could be considered justified – the other factor could also be longevity.  With a more substantial phase design, components are stressed less.  The cheaper motherboards often have cheaper phases, leading to potential heat generation issues – on the flip side more phases means more things to go wrong.

Overall however, the overclocking experience on the Z77-HD4 was better than expected, matching some of the other motherboards we have tested, despite our poor CPU!  In previous motherboards we have achieved 4.6 GHz with reasonable temperatures (albeit rather high voltages), and the Z77-HD4 matched this with ease.  In terms of manual overclocking options, we have Gigabyte’s three CPU Level Up options in the OS software, which performed with mixed results, with the top options placing too much voltage into the CPU.


Our standard overclocking methodology is as follows.  We select the automatic overclock options and test for stability with PovRay and OCCT to simulate high-end workloads.  These stability tests aim to catch any immediate causes for memory or CPU errors.

For manual overclocks, based on the information gathered from previous testing, starts off at a nominal voltage and CPU multiplier, and the multiplier is increased until the stability tests are failed.  The CPU voltage is increased gradually until the stability tests are passed, and the process repeated until the motherboard reduces the multiplier automatically (due to safety protocol) or the CPU temperature reaches a stupidly high level (100ºC+).  Our test bed is not in a case, which should push overclocks higher with fresher (cooler) air.

Automatic Overclock:

For automatic overclocking, the three options available to users are located in the EasyTune6 software in the OS.  These options are labeled in a traffic light system, and 1, 2, 3 with 3 being the highest overclock.  There is also an option for ‘Auto Tuning’, which should perform a stress test style analysis to find the best overclock.  Here are our results:

For CPU Level 1, the system attempts to apply a 41x102 overclock (4182 MHz) with a BIOS voltage setting of 1.335 V and a 0.150 V offset.  In the OS, this leads to a load voltage of 1.380 volts, a PovRay score of 1532.10, and a peak temperature during OCCT of 83C.

For CPU Level 2, the system attempts to apply a 43x103 overclock (4429 MHz) with a BIOS voltage setting of 1.340 V and a 0.150 V offset.  In the OS, this leads to a load voltage of 1.392 volts, a PovRay score of 1619.67, and a peak temperature during OCCT of 84C.

For CPU Level 3, the system attempts to apply a 45x104 overclock (4680 MHz) with a BIOS voltage setting of 1.345 V and a 0.150 V offset and LLC set to High.  In the OS, this leads to a load voltage of 1.380 volts, a memory error during PovRay, and a peak temperature during OCCT of 101C.

The Auto Tuning option in ET6 failed to load.

Manual Overclock:

Starting with our base settings (40x100 and 1.100 volts), we test for stability and increase voltage until stable.  When stable, the multiplier is increased and the process repeated.  Here are our results:

Software and BIOS

Unfortunately due to the timing of this review (very close to Haswell), we have not had time to write an extensive run-down of the BIOS and software on the Z77-HD4.  After playing with the software and BIOS, it performs identically to that of the UD3H and UD5H which we have reviewed, meaning a couple of thousand rehashed words with a slightly different twist related to the HD4.  If you wish to read up on the BIOS and software of a similar motherboard, please follow this link for the UD3H rundown.

    I'm just going to tell you now that your assessment is completely off -- a good amount of people can tell the difference in regards to the audio. Plenty of people like the option to XF/SLI later in custom builds. And some of those performance differences were shocking. That was an audio demonstration, but could mouse polling face that, too?

    Anyway, don't get me started on the audio, but there is reason for better solutions than this board.

    the "this board is probably aimed at the internet café market in China" is pretty shameful and below the belt Ian..

    I agree as well... Don't be so elitest! It's refreshing to see a decent $120 motherboard that sacrifices nothing that 95% of buyers require. Ian you are getting spoiled reviewing too many high end motherboards jammed with features that only 2% of the buyers require. Come down out of the stratosphere and join the rest of us.

    I also think this comment was way off ""this board is probably aimed at the internet café market in China"

    If anything, the board is for this market:

    And its what I build for myself, friends, family, and all the computers I build for my company, and anyone else who wants a great gaming experience without breaking the bank.

    "Shameful" and "below the belt"? o.O

    Do you always get your panties in a twist over such innocuous opinions?

    I have to admit I never use the on-board buttons on my motherboard, and find beep codes to be just as useful as an error code display. At the end of the day, you still need to swap out parts to troubleshoot an error, regardless of an error code display. Reply

    I agree with you I can't see a need for onboard power and reset switches on any motherboard. If the computer is set up they're worthless and if you're working on it you have your screwdriver right there to short out the front panel header. There really is no need at all for onboard power buttons. Reply

    I have to agree. I don't need dragons or ninjas on the box.

    I don't need heatsinks fashioned in some faux novelty bullet or landmine design.

    I don't need LED lit BIOS reset buttons (I've used mine twice in 5 years, so no, not needed).

    I don't need LED error notifications. I've had them and never needed them.

    I don't need umpteen video out options, I have a GPU card.

    I don't need built in audio, I have a sound card.

    I don't need built in ethernet, I have a Intel CT nic.

    I don't need a PS2 socket.

    I don't need more then 4 SATA ports (three if I'm honest is all I ever need)

    I don't need extra USB/Serial/Firewire expansion on the board.

    I don't need glow in the dark sockets or custom motherboard colours.

    I don't need 8 fan controller sockets.

    What do I need? A good quality stripped down board that without all that unnecessary crud would probably cost $50. Unfortunately no one seems to think anyone wants such a board.

    If most here were honest it's all they really need/want also.

    Good God, man, give it a rest. I hate it when someone starts ranting and then presumes to speak for the rest of us. Reply

    Sorry, I'll leave you to your motherboards and GPUs with dragons, neons and bullets on them.

    Was just stating that a lot of the features that motherboard manufacturers have loaded on 'as standard' are not really needed and only there to increase their slim profit margins.

    After 20+ years of PC building I'm kind of fed up paying for crud I don't need in order to purchase a 'quality' board.

    Why can't we have a good quality overclocking board without all the stuff we never use? Without all that stuff on there we could have much better signal paths, less noise and better power regs.

    That's a bit extreme. Most of us need/use the built in Network and Sound, and at least a DVI output is useful, even if you have a separate card. And practically everyone can use a lot of USB ports and headers. Reply
