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.

    Hi,

    On Gigabyte's homepage it says:

    4 x 1.5V DDR3 DIMM sockets supporting up to 32 GB of system memory

    regarding supported/recommended memory for this mainboard...

    How come 1.65V memory is used and what are the (possible) consequences?

    Should 1.5 or 1.65V memory be used?

    Best regards // BoJaKa

    Builders with more than a keyboard and mouse may have some issues with the UD3H. I recently got one because of some good reviews I read and the price/value of the board and I was on the cusp of exchanging it for something else because the board was just so unfriendly re: the VIA USB 3 ports.

    You need to populate the Intel ones before the VIA ones - not an issue. But the second you start populating the VIA ones you stand to get pretty frustrated. Each BIOS revision seems to fix the problem little by little (the saving grace thus far).

    The board also doesn't seem to like Sandforce. I am hearing Everest 2 is giving some folks problems as well. After the long term, I had a Solid 3 that kept causing issues. Granted, most folks would say that this is because the Solid 3 is simply a 'crappy SSD', but it did work on other systems so crappy or not there's something to be said about the pairing of it and the UD3H.

    The VIA audio didn't play well with my G930 headset. It would literally keep dropping out whenever I reboot and what this in turn did was set the G930 as default...that got annoying fast as I'd have to set the VIA back to default every, single, time. My fix was to unplug the USB key for the G930, a less than elegant response.

    Before unscrewing and repackaging the board for return to Newegg since everyone was telling me it was defective, I decided to try one more thing (based on how well things seemed to work when my G19 was on the front USB 2 port); I purchased a USB 2 bracket (4 port) and attached it to the 2 USB headers I had left. I then plugged my 2 hubs (housing my printer, gamepad, flash drives, etc) on the USB 2 ports, put my G19 keyboard on a VIA USB 3 port (as these are the only ports that work 100% pre-boot) and put my 2 USB 3 hard drives on the Intel USB 3 ports where I pretty much leave them. This is the only way I have been able to run the board stable.

    It was a lot to go through but things now work. If this were my first board I'd have been in trouble. Initially you don't experience the issues. It's when you move beyond a keyboard and mouse that you start seeing problems.
    I wish reviewers did more than just stuck a keyboard and mouse on these boards. I get that the review process can be grueling but most people nowadays have more than a KB and Mouse and a review should put a board through more paces than just overclocking. These manufacturers put so much into 'tweaking' the boards for OCing they are getting lazy with the rest of stuff. It seems a lot of boards experience USB problems, despite the various chips they use.
    I don't know if I'll ever use all of the onboard ports, I know that I don't DARE change anything, lest I go back to the reboots and crashes that occurred before I found my fix.

    So i see almost everyone here is dealing with the slow post time.
    Most of the time my post time is around 8 seconds (sometimes its around 4 seconds), while Dr. Debug lcd on mobo is showing a "99" post then it loads up the windows 7 loading screen (but sometimes after the post a blank screen with that "_" [underscore] appearance like when u open cmd which takes like at least 8 seconds also).. I have a Corsair Force GT 240gb and i want to get the most speed out of this system on boot up.

    Actually it wasn't 8sec it was more like 24seconds LOL and so sometimes its 8 seconds... Why is that taking that post so long to disappear? Reply

    Why I don't have that auto-oc option in my Ext4's bios/oc-tweaker screen? Reply

    Great review, it's cleared up a lot for me.
    It's been around 5yrs since I have updated my gaming rig.
    I would like to be able to run a variety of games at med. settings and also stream games!
    Also use a lot of Adobe products, video editing etc, and some 3d level design, but nothing to crazy!

    Budget upgrade:
    Intel i5-3570k
    G.SKILL Ripjaws X Series 8GB DDR3 2133

    Can't decide on one of these motherboards...
    I currently have a CM Gemini II LGA 775 heat sink, which the ASRock board supports = saves money!
    Do all these boards support a LGA 775 heat sink?
    I was looking at the ASRock z77 pro4 for around $109, but really like the ASRock ex4
    The 555 is nice and I would actually use it.

    Can someone please help me sway my decision?!?!??!?!?!?

    im seriously thinking about thie asrock extreme4 but the 2 PCI slots bother me. PCI-e came out in 2004. its 2012 time to ditch the PCI slots. if your getting a Z77 board and still use a PCI card its either time to upgrade that card or since you insist on using a 10 year old card stick with your old board.
