Gigabyte GA-Z77X-UD3H – Overview

For $160, there are a significant number of Z77 motherboards to look at, but Gigabyte wants you to buy theirs.  In this case, it is the Z77X-UD3H - their mid range, probably highest selling, Z77 SKU.  As a reviewer, it is important to not solely focus on the high end products, as it is the ones lower down the range that are often the best selling and closer to what people actually get in a system.  Too many high-end boards can leave a reviewer out-of-touch to what actually sells.

With the GA-Z77X-UD3H, we have a good priced Z77 board with a myriad a features to tempt users.  Gigabyte is pushing their digital power delivery and tweakable power delivery options, but we also have an mSATA port, a very good (and new-ish) automatic overclocking utility, and a cheaper board with all four video outputs.  The audio/network controller choice is a little different, and we actually get power/reset buttons on a mid range Gigabyte board.

Overall, I did not come across many things wrong with the board.  There are certain areas that could do with a little improvement, such as memory compatibility or fan controllers, but it seems like a user will have to stretch the wallet a bit for them in other products.  At $160, the board is definitely probing the lower end of the enthusiast market, so could be ideal for a more budget-oriented build.

Visual Inspection

Black and blue seems to be the order of the day when it comes to mainstream boards, as indicated by some of the previous boards but also with the Gigabyte GA-Z77X-UD3H.  Perhaps there is a sale on black PCBs and blue heatsinks?

Joking aside, Gigabyte intends to release two high-end boards initially – the Z77X-UD5H and the Z77X-UD3H, both in regular and WiFi variants.  The WiFi variant comes with a PCIe x1 WiFi card to be used in the first PCIe slot on the board, and aerials for the outside of the case.

We have the Z77X-UD3H in to review for the launch of Ivy Bridge, which should retail for around $160 MSRP.  Gigabyte has chosen a few different directions regarding which controllers are on the motherboard.  This should provide interesting results when it comes to performance.

The VRM power delivery comes with a relatively small blue heatsink next to the socket.   I’ve noticed that Gigabyte tend to have their memory closer to the socket than most other manufacturers, presumably in the name of performance due to shorter interconnects, but the downside is that it can restrict big air coolers.  Nonetheless, it all still conforms to Intel specifications, and there is actually a large gap to the south of the socket.

In terms of fan headers, there are only two within reach of the socket.  We have a 4-pin CPU header at the top near the memory slots, and another near the power/reset/ClearCMOS buttons at the top right of the board.  The other three headers on board are found at the bottom – one 4-pin beside the SATA ports, one 4-pin next to the USB headers and another 4-pin beside the TPM.

Along the right hand side of the motherboard, Gigabyte has given us a different style of power/reset/clear CMOS button that I have seen before.  The power button is big and red, whereas the other two are relatively small.  These will be of use to reviewers and overclockers, however having the ClearCMOS the same size and shape as the reset button may lead to several bad fumbling for the right button followed by several four-letter expletives.

Further down is another style choice – an additional power connector for the PCIe and system, but this case it is a SATA power connector.  I prefer this to the awkward molex connectors we see on other products.  Below this are the standard six SATA ports from the PCH – two SATA 6 Gbps and four SATA 3 Gbps.  Below this is the handy two-digit debug display.

Along the bottom of the board, from left to right, we have the front panel audio, SPDIF header, a 4-pin fan header, the TPM header, three USB 2.0 headers, and another fan header.  At the top of the PCIe is our mSATA connection, useful for mSATA SSDs and boot drives to save case space.  In terms of PCIe, Gigabyte has installed a little nugget of common sense, giving enough space between the first two full-length PCIe for GPUs.  However, in the x1, x16 (x8 in multi-GPU), x1, x1, x8, PCI, x4 setup, only the first two full length PCIe are for graphics output – the final one is a PCIe 2.0 x4 connector.  This would be better served if it were a slightly different color to the other PCIe x16/x8 connectors.  Also with two full length GPUs on board, the user will have access to two PCIe x1 connectors but the PCI connector is blocked.

I know Gigabyte will make a few people jump with joy in relation to the back panel layout – no USB 2.0!  From left to right, we have a PS/2 combination port, two USB 3.0, D-Sub, DVI-D, an Optical SPDIF output, HDMI, DisplayPort, two more USB 3.0, two eSATA, gigabit Ethernet, a final two USB 3.0, and audio outputs.

One of the odd choices of Gigabyte is their network and audio controllers.  On nearly every board I have reviewed, we get either a Realtek, an Intel or a Broadcom for the network, and a Realtek or Creative audio solution.  Gigabyte has decided to jump in with an Atheros network controller, and a Via VT2021 audio.  It will be interesting to see if this has an effect on our test capabilities.

    Yes, it is a very important feature. The Ivy Bridge IGP can drive 3 monitors. 4 display outputs means 3 of them are digital.

    Discrete GPUs increase idle power consumption, an as of this post none of them have particularly good open source drivers. Some of us just want lots of screens, good compiz performance, and silence.

    I have been building a series of matx htpc/gamer machines.

    I have one with the basic

    Gigabyte GA-B75M-D3H mATX board

    and one with the

    Gigabyte Ga-h77m-d3h mATX board.

    I want to decide between

    the ASUS P8Z77- m pro mobo or

    the ASUS p8z77-m board and

    last but not least the

    Gigabyte Intel Z77 LGA 1155 AMD CrossFireX/NVIDIA SLI DVI/HDMI/DisplayPort Dual UEFI BIOS mATX Motherboard G1.SNIPER M3 .

    I am liking the two builds I did with the lowend gigabyte boards and some intel i5 t2500t cpus I want a better board but I don't have many reviews to go by.

    It just doesn't make a whole lot of sense to me. Are most DIY'ers really opting for ATX? Should they? I'd bet most people only plug in a video card and maybe one other card such as wireless or even a tuner. Every other possible need they may have would not only be met by mATX but even ITX is pretty full featured these days.

    You'd think mATX would be what most boards are targeted at, and leaving ATX for extreme builds/bragging rights. It's just like those high end video cards, most people don't buy those, rightfully and importantly so. Those should be the premium prices, and mATX should have a lower price. The focus just feels off.
  • Zoomer - Monday, May 14, 2012 - link

    You mentioned people want mATX board. There by itself probably means that it can command higher prices, due to higher price tolerance of the purchasers.
  • Caeric - Monday, May 7, 2012 - link

    Enjoyed the review. I still have an old AMD dual core, and I'm considering a new system in the next couple of months so these help a great deal.

    I did find one error in the article, under the ASUS board:

    "The ASUS P8Z77-V Pro retails at $225-$235, essentially $100 less than the ASRock Z77 Extreme4..."

    It should say "...essentially $100 more than the ASRock..."
  • Movieman420 - Monday, May 7, 2012 - link

    Curious as to this controllers' performance vs the ever present Marvell controllers. Does it use a pci-e lane or usb3 for it's bandwidth?
  • FozzyofAus - Monday, May 7, 2012 - link

    Great review.

    I'm leaning towards mATX as well for this build as I've never used more than four expansion slots and currently I'm only using 3 (one is USB3 which won't be needed in the new board).

    I'd like to have a bit more room in my current case and the option to reuse this motherboard in a smaller case in future if I upgrade my main rig to Haswell next year.

    Any chance of adding Asrock Extreme4-m to the next motherboard roundup?
  • spronkey - Monday, May 7, 2012 - link

    Sorry guys but this review was a bit average. Comment on the various different controllers used by the motherboard manufacturers but don't offer any kind of review on them?

    The good additions: DPC latency and boot time.

    The missing? Well everything else.

    I was especially hoping for a comment on the VIA audio on the UD3H - it's been a while since I've seen VIA codecs on mainstream boards.

    I'm also amazed that you didn't slam the ASUS board for it's price and lack of features. Realtek 892? On a board that's nearing twice the cost of the ASRock? Seriously?

    No comment on the durability of the boards either? Hrm. No separation in testing of the different controllers on each board?

    A bit lacking, sorry.
  • ggathagan - Thursday, May 10, 2012 - link

    Perhaps you're commenting on the wrong review.
    As Ian stated multiple times throughout the review, Asus is using Intel NIC's on their boards, in this case, the Intel 82579V.

    Durability is a function of time. Please point out the other motherboard reviews that covered durability.
  • spronkey - Thursday, May 10, 2012 - link

    He stated ASUS were using Intel, sure. But didn't get into any details other than stating they exist about the fact that there are multiple USB3 controllers and SATA controllers on each board. No benchmarks comparing them etc.

    In fact does it even mention which controllers were tested?

    And Durability is a function of construction quality and time. It would be nice to see comments on points such as board weight and flex, quality of soldering, quality of components used on the board (according to an electrical minded person on OCN, Gigabyte uses significantly higher rated MOSFETs than other manufacturers), temperatures of chipsets and VRM circuitry. These are things I can't easily find out by reading manuals.
