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.

    Indeed. Personally im looking at the Intel DH77DF:
    http://www.intel.com/content/dam/www/public/us/en/...

    I dont see the need for anything bigger than mATX anymore. And for most mITX will do everything and abit more.

    Personally I got a hint from another person. So I will be looking at the DH77DF, 2x8GB, GTX 680 and a i5 3570 and put it into a Silverstone SG08.
  • hybrid2d4x4 - Monday, April 9, 2012 - link

    Agreed. mATX or smaller for me plz!

    What is the actual significant difference between Asus P8Z77-V and P8Z77-V Pro? The only things I noticed were a few more phases in power supply (not significant).
  • Byte - Sunday, April 8, 2012 - link

    The only diff I see is the 12 vs 8 power phases, extra USB3.0 header, and pictures look like it includes a usb and esata pcie 1x card.
  • ASUSTechMKT - Monday, April 9, 2012 - link

    Pro offer higher quality back I/O bracing for the display connections,
    High phase count 12+4
    Additional front USB3 front header
    ESATA via bracket
    Additional fan header

    Otherwise all other key features and hardware implementation is the same.

    Given this statement on the first page, why does the chart indicate that the Panther Point chipsets provide 4 USB 3.0 ports?
  • Knifeshade - Sunday, April 8, 2012 - link

    First page, the paragraphs detailing the various features. You spelled Cougar Point in place of where I think you mean to say Panther Point....

    PCIe / PCI info in the last page table would be appreciated. Good overview. Quite curious to see if the memory stuff from Asus actually does anything.
  • MrSpadge - Sunday, April 8, 2012 - link

    All 6-series chipsets are said to support PCIe 3 in this table. Would that work with Ivi and a proper GPU? Would be the first time I heard about this. And since PCIe 3 is supposed to be a new feature of the 7-series I suppose it's a typo.
  • GreenEnergy - Sunday, April 8, 2012 - link

    Well, alot of 6 series boards supports PCIe 3.0 due to the controller is on the CPU (Ivy Bridge). Essentially the only reason besides BIOS for PCIe 3.0 support on the 6 series, is the added switches for splitting the PCIe x16 into two x8. Thats also why the basic 6 series boards got a bigger chance of PCIe 3.0 support.
