Gigabyte GA-Z77MX-D3H—Visual Inspection

In a twist to the previous motherboards, Gigabyte sent us a micro-ATX sample, the GA-Z77MX-D3H. While still a Z77 product, capable of dual GPU setups, we have a motherboard aimed at the cheaper end of the spectrum. This is shown with what looks like a 4 + 2 VRM power delivery, and the relatively small sized heatsinks. We are also limited in terms of fan headers (three), and rear panel USB 3.0 ports (only two) compared to the Z77X-UD3H WiFi bigger brother.

The socket itself is clean with little obstructions—fan headers are found below the VRM heatsink, where we have two of the 4-pin variety. The other fan header on board can be found at the bottom next to the TPM.

Despite being a cheaper small motherboard, we still have typical Gigabyte features, such as dual BIOSes next to the USB 3.0 header underneath the 24-pin ATX power connector, but only the SATA ports from the PCH. This means two SATA 6 Gbps and three SATA 3 Gbps. The chipset heatsink is also small but has enough surface area to keep Gigabyte confident of its functionality.

The south side of the board is relatively naked, with a front panel audio, fan header, TPM and two USB 2.0 headers. Given the look of the board and that it does not display many potential features (presumably to fit into a price bracket), I was not expecting anything elaborate such as power/reset buttons.

The PCIe layout is aimed at users wanting dual GPUs or users needing an extra PCIe device alongside their GPU. The PCIe layout becomes x16 (x8 on dual GPU), x1, x8, x4, with this final x4 only being PCIe 2.0.

The rear IO panel is more substantial than I assumed, which can only be a good thing. From left to right we have a pair of USB 2.0 (black), a combination PS/2 port, D-Sub, DVI, two USB 3.0 (blue), HDMI, four more USB 2.0 (black), gigabit Ethernet, and standard audio jacks with a combination optical SPDIF output.

As with the Gigabyte Z77X-UD3H WiFi, this Z77MX-D3H comes with an Atheros/Via network and audio combination. Given the lack of features on the main area of the board due to the size and the audience this product is aiming for, it seems good if all you want is a stock processor and a working Ivy Bridge system with no frills.

    The article says only 2 USB 3.0 ports, but the table indicates 4. Which is correct?

    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.

    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.

    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
