The motherboard scene contains around fifty shades of grey – whatever size, whatever feature set, if a user cannot get what they exactly want, something similar should be available.  The only questions that follow are: does it work properly, and is it worth the money?  Today we are looking at the Gigabyte GA-Z77X-UD5H (or the Z77X-UD5H, depending on location), a motherboard with dual NIC, up to ten USB 3.0 ports, mSATA, three-way GPU without a $30 PCIe enhancing chip, TPM, extra SATA 6 Gbps and the full array of video outputs for only $180.

Gigabyte GA-Z77X-UD5H Overview

Ever since I started reviewing, I have been critical of Gigabyte – they seem eager to put out a product that works and quickly bring it to market, as shown by the number of 'first to market' features Gigabyte like to advertise.  The usefulness of these new features can sometimes be questionable, or could intially lack the grade of finesse we see on these features several months down the line.  Gigabyte is a very sales-driven company, with a strong marketing ethic, thus it sells a good number of motherboards, and is a top-tier motherboard manufacturer with hands in many markets.

Competition, as always, comes from all sides – users are perhaps moving away from the standard desktop scene into mobile devices, or other motherboard manufacturers want a slice of Gigabyte’s large pie.  The motherboard business, while growing, is not growing as fast as it once was – in order to gain market share it has to be taken from someone else.  This has caused companies like Gigabyte to knuckle down hard and find ways to remain competitive.

One Gigabyte tactic (of late) is to take its motherboard lineup and attempt to push it down one price point.  This is either through manufacturing costs, bundling, special deals and presumably a myriad of other ways internally to achieve this.  We saw this on the X79-UD3 especially.  The potential downside of perhaps scrimping to meet a lower price point is sometimes the perception of the absence of effort, particularly when there is a lack of substance to a motherboard bundle – it needs to feel that the board is good value, rather than just be good value.

Here steps in the Z77X-UD5H.  On paper it has a range of included extras – dual NIC, extra SATA 6 Gbps ports, three-way PCIe 3.0 GPU gaming without a $30 expansion chip,  an mSATA port, TPM, up to ten USB 3.0 ports and a full range of video outputs, all in a $180 (MSRP $200) bundle.  Competition at this price point comes from the ASUS P8Z77-V LE Plus, the ASRock Z77 Extreme6, the MSI Z77A-GD65, Gigabyte’s own G1 Sniper M3, and a for a little more, the ASUS P8Z77-I Deluxe and Maximus V Gene.  All these boards fall in the $170-$200 window on Newegg at time of writing.

Performance wise, the Z77X-UD5H gets a high grade across the board.  It benefits from having MultiCore Enhancement, giving an extra 200 MHz when fully loaded compared in Intel Turbo specifications – this helps the Gigabyte push the board in CPU related benchmarks.  IO benchmarks are mid range, reaching the upper echelons on occasion.  The single flaw in Gigabyte’s rather nice deck of cards is the DPC Latency test, which suffers initially at the hands of the EasyTune6 monitoring software (3000 microseconds+), but when this is disabled it hits a value double that of any other Z77 board.  Judging by other manufacturers who have had this issue, a simple BIOS update should fix it.

The Gigabyte BIOS has slowly grown on me since its inception in graphical form.  When I first covered the BIOS, it was slow and unresponsive and was not nice to play with.  On the Z77X-UD5H though, it is smooth sailing with almost all the options easy to hand.  The software supplied with the motherboard, in the form of EasyTune6 and 3D Power, really needs a swift kick in the rear to bring it into the 21st century.  In addition, users who want in-depth fan controls will need their own solution.

The Gigabyte Z77X-UD5H comes with a three-year warranty in North America, and for an extra $30 comes with an included WiFi card and antenna in the form of the Z77X-UD5H-WB WiFi.  Overall, the Z77X-UD5H lights up the $180 price point like a beacon and is placed well for significant sales.

Visual Inspection

Gigabyte have three different aesthetic styles for the range of motherboards they produce – green and black for their gaming series, blue and black for their channel boards, and blue/white for their budget SKUs.  The Z77X-UD5H is placed firmly in the midrange of Z77, resulting in a blue and black visual:

The power delivery sections are covered by some beefy heatsinks, both of them connected via a heatpipe down to the chipset heatsink, which comes with fins to aid cooling.  The socket itself is sized to Intel specifications, with power delivery coming close on two sides, mSATA on the south side and memory on the right.  Users of large air coolers may struggle to deal with the heatsinks, as they measure approximately 32mm high from the PCB.  There are three fan headers found around the socket area – one 4-pin to the top right of the socket, one 4-pin to the top left near the power connector, and another 4-pin the other side of the memory near the power button.

Down the right hand side, we have a trio of power/reset/clear CMOS buttons.  The latter two are of similar size and shape, leading to perhaps a few four-letter profanities by enthusiasts using this board to overclock should they hit the wrong button, but the power button is big, red, and thus easy to hit first time.  Under these is a two-digit debug LED, useful for troubleshooting POST issues, and a 4-pin fan header.

Gigabyte motherboards typically have a very busy motherboard between the right hand edge and the memory slots, and this is true here also.  Continuing down the right hand side, we have the 24-pin ATX power connector, a USB 3.0 header (VIA VL810), and a SATA power connector (to give the PCIe extra juice).  Typically, the PCIe extra power header is found above the PCIe, but I prefer it here as it makes cabling easier.  Underneath these are eight of the SATA ports – four SATA 3 Gbps in black from the chipset, two SATA 6 Gbps in white also from the chipset, and two SATA 6 Gbps in grey from a Marvell 88SE9172 controller.  The other SATA 6 Gbps ports on the motherboard are split between the single grey SATA port on the bottom, and the eSATA port on the IO panel.

Along the bottom of the board are the headers – from right to left we have a pair of USB 3.0 headers (good for four more USB 3.0 ports from VIA controllers), the SATA 6Gbps port, a BIOS switch (for the dual BIOS system), the front panel connectors, two USB 2.0 headers, an IEEE1394 header, and a Trusted Platform header.  This TPM is here as Gigabyte insists that a number of their customers request it, especially in business scenarios.

The PCIe layout is designed to work around the board design – due to the mSATA port between the socket and PCIe (on other boards we see the mSATA near the chipset, or between the PCIe slots), we start with a single PCIe x1.  The rest of the PCIe are an x16 (x8 in multi-GPU), x1, x1, x8 (x4 in tri-GPU), PCI, x4.  The Gigabyte Z77X-UD5H is different to all the other Z77 boards we have tested so far due to the PCIe layout for multi-GPU setups:

With the Ivy Bridge platform and Z77 chipset, we have the following possibilities for separation of the sixteen PCIe 3.0 lanes from the CPU:

x16 or
x8/x8 or

We see the first two options on most of the motherboards on sale today.  This is combined usually with four lanes from the chipset of the PCIe 2.0 variety.  Manufacturers can also add a PLX 8747 chip (nominally another $30-$40 increase on the cost of the board) to increase the PCIe 3.0 lanes to 32.

What makes the Gigabyte Z77X-UD5H different is that it takes the third option – x8/x4/x4 on the PCIe slots, all PCIe 3.0.  In dual mode, the system will act x8/x8, and in single mode we get one x16.  As our previous reviews use the x8/x8 method with an additional four lanes from the chipset for the third GPU, our gaming tests show the difference between these two setups.  We also have some PLX 8747 boards coming up for review shortly to see how they affect the rankings.

On the back panel, Gigabyte have pushed the boat out as much as possible without putting a WiFi module on the back panel (note the Z77X-UD5H-WB WiFi version of this board comes with an add-in card for WiFi and is $30 more MSRP).  We have the full range of video outputs, an optical SPDIF output, two USB 2.0 (red), IEEE1394, eSATA 6 Gbps, an Intel NIC, a Realtek NIC, four USB 3.0 ports (all from the chipset), and audio jacks (from Realtek ALC898).

For our money, the inclusion of all those USB 3.0 headers and dual NIC will get a lot of attention.  Then there is also the mSATA and extra SATA ports also to consider, alongside the PCIe 3.0 three-way GPU support.  There is a lot of bang for your buck in this board just on functionality alone.

    As a competitive overclocker, I have used GBTL when pushing the BCLK of these boards as far as my CPU will allow ( I like GBTL - no mess and no fuss. But it is understandable why they do not include it in the Support CD, and hence why it doesn't really get a mention here. I did touch upon it very briefly in the overclocking section of the Z77X-UD3H review back at Ivy launch. As for voltage read-points, they are mentioned briefly in the board features, but I am also in agreement that perhaps the implementation of other manufacturers is more beneficial in our very niche usage scenario :)


    PS On the multi-board reviews I try not to take anything out from what is in a single board review. Every benchmark, test and bit of analysis in each of them gets put in :)
  • Nickel020 - Wednesday, July 25, 2012 - link

    Oh, I missed the part about the GBTL in the UD3H review. While I haven't goten around to playing with my UD3H, I have found the Asus AI suite very practical for "normal" overclocking and I believe the GBTL will also be a real benefit for anyone working out a good 24/7 overclock. If I didn't knwo about it already I certainly would want to read about in your review if I was going to get this board for 24/7 OC.

    I also missed you mentioning the UD3Hs voltage read points, but in any case there's still an error in the conclusion though where you implicitly state that the UD3H does not have voltage read points (in the part about the GD65).

    I know you run the same benchmarks, but I find the text/user experience more interesting than the benches, and there's definitely more text in a single board review! The benches I only care about to see whether a board has a significant performance issue, since I'm not into competitive OC I don't care about slight differences that I won't notice anyway.

    Conderning the benches, I'm also a little surprised that you somewhat praise GB for auto-overclocking the CPU. IIRC Anandtech has been opposed to that in the past, since it's technically overclocking and thus theoretically voids your CPU warranty. It also makes it hard to compare board performance when CPU settings are actually the same, such as when using a manual overclock. I know it's considerably more work, but I would love to see the benches with the CPU forced to run at stock settings added to the charts, the current version is an apples to oranges comparison imho. For someone just looking at the charts (and not the text, as many do...) the current ones give a very wrong impression, they make it seem like Asus and GB perform better, when without the auto-overclock, they might actually be worse...

    Most users of these boards never touch the BIOS, let alone update it. This is why we run the boards at default - some manufacturers are being more aggressive with their settings and that is what you are paying for. If that aggressive setting compromises stability, then that can also be an issue. Thus it is a like-for-like comparison, as if a user was taking the boards out of the box and then just strapping in a CPU.

    After all, if we start changing the application of Turbo modes, what else do we change? Setting the voltage equal on each board to get a VMM reading that is always the same across the range? How about disregarding any board that uses x8/x4/x4 PCIe 3.0 against x8/x8/x4 PCIe 2.0? Default is the choice because that's what most users will end up with. Visiting some LANs recently, you would be surprised how many people buy 2133+ kits of memory and not enable XMP. That's the reality of it.

    I used to be wary of this feature (as per my review of the P9X79 Pro, where I disabled it and was severely disgruntled), and still am as it results in motherboard manufacturers artificially inflating some results as to what you would expect. But this did happen before in earlier chipsets, when one manufacturer would run 100.5 BCLK, and the next would use 101.3, and even 102 BCLK, stating 'that's just how the design works'.

    There's nothing we can do to change this, so I am taking the position of sitting back and analysing what they are doing, and how aggressive they are taking this philosophy. Any good reviewer will recognise what is pure statistical variation and not assign world class status to a result that is 0.01% difference.

    With regards the warranty, it is a tough hammer to nail down. Would a pair of companies ever advertise that by default their settings technically breaches warranty? Or how would Intel take it, given that technically none of the cores ever went past the top turbo mode? Without a direct response on the issue, it's not worth speculating. I've known users to repeatedly successfully RMA CPUs they've overclocked on LN2 way too hard and broke them, so we don't really know if Intel will draw a line much.
  • Nickel020 - Thursday, July 26, 2012 - link

    It's certainly a matter of opinion. As an "enthusiast" I'm of the opinion that a board should not overclock without my knowledge/express wish (since I can easily do so myself. Practically the overclock of course has no bearing on CPU warranty (the CPU also being the very last PC component that you're likely to need warranty on...).
    I agree that for the average user this is actually added value, a slight performance bonus at absolutely no cost other than a little bit more power consumption. Maybe point out both sides in future reviews? That way everyone's happy :)

    PS: Please do fix the error in the UD3H, GD65 conclusion, it's wearing me down ;)

    "For the price we lose PCI and mSATA over the Gigabyte, but gain SATA, voltage read points, [...]" <--- wrong, maybe say "better implemented voltage read points"? ;)

    Thanks Ian :)

    No VGA port, no floppy connector, no buy .
  • Dustin Sklavos - Wednesday, July 25, 2012 - link


    First, it does have a VGA port. Why you would want to use one escapes me now, but it's there. still need a floppy drive and can't make do with a USB 2.0 one? Almost no modern motherboards include floppy connectors because floppy disks are horrendously outdated and that real estate can be better employed elsewhere.
  • mystikl - Wednesday, July 25, 2012 - link

    I was actually making fun of the guy who posted the second comment! Why on earth people still need those ancient connectors is beyond me. Some may argue that some ancient software doesn't run without that specific port, but software that old doesn't require a computer with a quad core, 16 GB RAM and 3 videocards.
  • shin0bi272 - Wednesday, July 25, 2012 - link

    bios flashes on some boards still require a floppy disk... even on a quad core.
  • SodaAnt - Wednesday, July 25, 2012 - link

    Luckily those boards have floppy ports then.
