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.

    Article: "With a lot more controllers to initialise on board, the ASUS P8Z77-V Pro requires at default 20.47 seconds to reach the windows loading screen. By disabling controllers that aren't used, a time more like the ASRock could be achieved."

    Did you actually test this?

    And a suggestion: please test Intel DZ77BH-55K motherboard. It is the only board besides MSI to use the better ACL898 and Intel LAN chip but without other useless bulk (like secondary LAN etc). It seems to have superior BIOS to many others.

    Hi Paapaa125,

    I should have an Intel Z77 board inbound to test. I have about 5 others to test as well, and some ITX. Currently reviewing boards in my spare time, so please bear with me as I get through them all! :)

    Great to hear that! And no need to rush, I can wait :) I hope you test these things:

    Boot time. Fan control settings. Power consumption. Lan speed/CPU util. Audio quality. And check if the Turbo Boost settings actually are identical. Otherwise the benchmark results are unbiased.

    I'm actually more interested in other features than pure computational speed and benchmark scores. The differences are usually insignificant, but the differences in other areas might be big.

    Somebody further down the thread posted a message that they configured their Asus 'board to POST much quicker than above.

    I second request for Intel board reviews! I am particularly interested in the DZ77GA70K as well as the 55K mentioned by Paapaa125. I've been hearing good things about the GA70K but I'm hesitant to commit without finding out about POST times and I'd also like to see if performance is the same between the 55K and 70K.

    Can you give us realistic power supply measurements? I am interested in building a fairly fast system that is pretty much always on. So the idle power needs to be as low as possible. I would use a smaller power supply that is at least 85% efficient @ 50 Watts. And no video card. With just one SSD and one optical drive. My best napkin-guess would be an idle power of 40-45 watts.

    That's a fair guess for idle. The problem you will have is that ideally you will want a high efficiency supply that at idle is at least 20% loaded. For you 40-45 idle that means you would need a supply probably not more than 200 watts. It is hard to find a 80+ supply at those lower powers. You might consider a small form factor supply. This is just about fits your requirement:

    That might be a good choice. I wonder if I would still be able to hit 4.3GHz with that supply. I would definitely keep it at stock volts. Reply

    ..or try the 80+ gold alternative from seasonic, if you can find a shop that sells it, 300 or 350W - optionally modular.

    Unfortunately without any PCIe 6 pin power connector, if you so should get tempted...

    Well that review went as expected. MSI underperformed, Asus was needlessly expensive, Gigabyte had memory issues, and Asrock OC'd with lower voltages. That;s mirrored my experiences in the past few years. Reply

    Thanks for the nice benchmarks, USB, SATA, LAN, Power Consumption, ...
    Especially, I appreciate the "DPC Latency" and "Boot Times" tests.
    It very useful and practical!!!
    Keep working, AnandTech.
