Gigabyte GA-Z77X-UD3H WiFi—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 WiFi. 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 WiFi 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 weighs in at 6 + 4 phase, which is by no means substantial (remember the ASRock Z77 Extreme4 was 8 + 4 and less expensive), and comes paired 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 not 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 fumblings 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 near 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.

    The article says only 2 USB 3.0 ports, but the table indicates 4. Which is correct?
  • repoman27 - Sunday, April 8, 2012 - link

    I didn't see your comment and posed a similar question, but I'm fairly certain the answer is that there are actually 4 SuperSpeed ports provided by the 7-series chipsets. If you look at the block diagram shown for the Intel DZ77GA-70K motherboard it looks like they clearly used two 3-port USB 3.0 hub chips to arrive at a total of 8 USB 3 ports. Which also brings up the point that by leveraging the integrated USB 3.0 capabilities, motherboard manufacturers can add as many USB 3.0 ports as they like by using far less expensive hub chips instead of full blown controllers which also require a PCIe lane apiece.

    And speaking of PCIe, I also wonder about where Ian says, "These are known as PCIe 3.0 PLX PXE chips..." I'm guessing that he's referring to PLX's PEX 874x Gen 3 PCIe switches, but it's stated a bit oddly.

    Is the wifi card on the deluxe going to be accessible? Be nice to get a killer 1102 in there.
  • johnpombrio - Sunday, April 8, 2012 - link

    Yeah, the WiFi connection(s) on the ASUS Pro and Deluxe depends on a small WiFi module that plugs into a particular slot. These will be interchangeable AND I have seen ASUS showing off a WiFi/ 60GB SSD drive going into that slot. The Pro looks like just a receiver while the Deluxe has a WiFi router built in but I am REALLY guessing on this. I think I will go with the Deluxe just because it has a couple of features I like and the WiFi router combo will be just gravy.

    Our MCombo Card ( which is on the Maximus V Gene and upcoming Formula should not be confused with the solution on our channel boards ( Standard -V, Pro or Deluxe ). The MCombo will allow you to install any MiniPCI-E or MSATA cards into their corresponding slots.
  • ASUSTechMKT - Monday, April 9, 2012 - link

    The module which connects to the back I/O panel can be opened. While not promoted as being DIY there is nothing stopping you from installing your own mini PCI-E wireless controller.

    I know I've asked for this before, but if you're going to do a big roundup of all these motherboards (which I'm looking forward to, as I plan to upgrade to Ivy Bridge on release), then please please test the boot / POST times to compare between the boards!

    Just the time it takes from hitting the power switch to when it starts to actually run the bootloader off disk. Or until it displays the "please insert boot media" - the actual time the bios contributes to the total boot time. This is something that can really differentiate between different bios implementations and would be really useful to know when choosing.

    I know having RAID and on board devices turned on make a big difference, so a baseline of everything non-essential turned off, or just those devices that are present on all boards would make sense.
  • Nihility - Sunday, April 8, 2012 - link

    Seriously, please test POST times!

    Especially with the 6 Gbps Marvel controllers. Those damn controllers can take over 10 seconds to boot. That can easily be as much as the entire system.
  • risa2000 - Sunday, April 8, 2012 - link

    I would be quite interested in this one.
  • eXces - Sunday, April 8, 2012 - link

    would be very pleased for an ITX review! Especially Asus P8Z77-I Deluxe
    Thx
