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.

    Can anyone explain the value in multiple Ethernet ports? Outside of being server board, and some specialized workstations, the practicality (and added cost) of multiple Ethernet ports escapes me.
  • IanCutress - Wednesday, July 25, 2012 - link

    Connecting to multiple networks, redundancy, teaming for better throughput, connecting via ICS, VM throughput, one specifically for backups, separation of traffic (i.e. you could have a combo web/database server, same network, put all web traffic on one NIC, db traffic on the other, makes it easier to calculate loads for traffic types). If you're streaming from a NAS that supports teaming, then the improved bandwidth can benefit users that stream from that device. Agreed, it is a perhaps a niche scenario, but there are enough users that want it. The Realtek NIC + Audio is a relatively cheap bundle, but some people prefer the Intel NIC. So why not have both, as long as the price for the user is reasonable.

  • Snotling - Wednesday, July 25, 2012 - link

    If your NAS has two ports... you can team up your nick on both ends.

    If your two NICs have different chip-sets then it may be for compatibility reasons. Some businesses will want to use only the Broadcom or only the Intel or Marvel... etc. Maybe at some point you can save downtime if a driver update causes a problem either by being bugged or missing.

    Load balancing, bridging networks, Acting as gateway or firewall... even if you do not actually run a server on the board you may want to do it for test purposes or some weird networking condition. Like having two different VPNs that require you to be on two different subnets.

    I admit, most of this is exceptional conditions but the exceptions addup and higher end boards aim to cover the needs of those who may run into those situations or actually need them.
  • Grok42 - Wednesday, July 25, 2012 - link

    I can't figure it out either. I've built boxes with many nics before for routers, gateways and bridges. Almost all the servers I've built have had 4 nics. However, I can't imagine using the two nics on this board for anything. Why would I want to build a NAS box with SLI and overclocking? Why wouldn't I get a much different board and add a good discrete NIC board with multiple ports? At the consumer level I can't imagine doing any of this. My file server only has a single gigabit nic and is WAY faster that I need. I can move GBs of files in just a few seconds between it and my workstations. At work we have 10GB and we team ports to increase even that so I know there are needs for higher speeds, I just can't figure out a reason at the consumer level this board is obviously focused on.
  • Einy0 - Wednesday, July 25, 2012 - link

    I own this board, it is amazing thus far. I haven't really had a chance to really push it too hard yet... One of these weekends I will try some overclocking. The 3770K is so fast, I'm still getting used to it. I am really impressed with the Z77's SATA controllers. My Vertex 4 is topping out at about 562MB/s for reads and my 4 disk (500GB WD Blue) RAID5 Array is hitting around 362MB/s for reads. I would love one more USB 2.0 header or a USB 3.0 to 2.0 header adapter. A non Realtek audio codec would be terrific too...
  • vailr - Wednesday, July 25, 2012 - link

    There's evidently 2 board versions of the UD5H:
    The older version has a space in between the 2nd & 3rd DDR3 slots, with blue capacitors.
    The newer version has no space in between the 2nd & 3rd DDR3 slots, with purple capacitors.

    Question: why doesn't Gigabyte provide drivers for the VIA USB 3.0 ports? There are some VIA USB 3.0 drivers on, but those fail to install on Windows 7 64-bit.
  • Sabresiberian - Thursday, July 26, 2012 - link

    One of Gigabyte's strengths is that they've long had dual Ethernet capability, but -

    Why only one Intel? Is it really that much more expensive to just put the best in here?

    I think your read of Gigabyte has been right on the money Ian, I've long thought the same, and wondered why some media types blew their horn so loudly.

  • Zak - Saturday, July 28, 2012 - link

    I see no point in adding FireWire any more... I'd rather have two eSATA ports or another SPDIF output. Any why having DVI, DP and VGA? Waste of space. I really doubt anyone has a need for all three simultaneously. If someone needs to use VGA they can use DVI or DP adapter.
  • Zak - Saturday, July 28, 2012 - link

    Typo: "Overclocking on the UD5H was a mixed back of results"
  • JimDicks - Saturday, July 28, 2012 - link

    This GB mainboard comes with a Marvell 9172 6Gbit/s S-ATA controller, almost same as my GB mainboard. When I recently bought a 6Gbit/s SSD and connected it to the 'superb' Marvell, it only reached about 250MB/s instead of the advertised 600MB/s. A whole afternoon searching and reading forums and specifications revealed that most of these 3rd party chips have a higher latency than the Intel/AMD south bridges, and reach much lower data rate than advertised, because they are connected via 1, maximum 2 PCIe 2.0 lanes to the mainboard. That means that a controller with 4 6.0Gbit/s connectors would need 2.4GB/s to transfer, yet it can only theoretically transfer 0.5GB/s (1 lane) or 1.0GB/s (2 PCIe 2.0 lanes) to the mainboard. In fact, the practical PCIe speed is much less.

    I recommend that Anandtech not only checks USB speeds, but also S-ATA speeds via the 3rd party chips, the southbridge and via external PCIe x8 SAS Raid Controller (ie. LSI MegaRAID SAS 9240 or 9260). The latter could also be used to check the practical PCIe bandwiths.
