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.

    Quote: Native USB 3.0

    The other long awaited addition found on Panther Point is the native implementation of USB 3.0 that comes directly from the chipset. The chipset will only provide two USB 3.0 ports,

    ------- end quote

    I think Z77 natively support 4 USB 3.0 ports

    When you write sentences like this:

    "ASUS have a lot to live up to with its Ivy Bridge Pro board."

    You do realize that you're mixing a plural verb and singular pronoun for the same damn thing...Asus in this case. First, you use a plural verb talking about Asus and then use a singular pronoun for Asus in the same sentence. You cannot do both; well, I guess you can, but you show you have no clue about English grammar and look like you dropped out of third grade.

    Get a copy editor! How can anyone take this site a professional when the writing borders on illiterate?

    You should higher a sand removal specialist to take a look at you're twat.

    @C'DaleRider -

    You do realize that... you're the illiterate one, don't you?

    "ASUS have" is perfectly legitimate English, and is in fact what you will hear in England itself. "ASUS" is a company of people and can be taken as singular or plural.

    For me, the AT editors just made major points right in this set of comments by correcting another ignoramus, who was misusing "begs the question".

    Now, can we get back to fan headers?

    no, there are errors STILL all over the place in this article... it's horrid... when your site is 99% words, please make them as easy as possible to comprehend...

    PLEASE LEARN TO WRITE LIKE ANAND, THX!

    Anand, for the love of god, pay a little more to hire a little more education (SEE WHAT I DID THAR??)

    "Biostar have unfortunately put much effort in here, with only three to play with..."

    Should be a "not" in there I suppose.

    I do not understand why non express PCI slots are still on boards. The only one to see the light is MSI, and if they had a bit better performance I would switch from ASUS for my next mobo in a heartbeat. Also, why do these boards have a VGA connector (D-sub)? Intel HD graphics can only support 2 displays max, and if you have more than you should get a dedicated graphics card anyway, and probably already have. I don't see the point.

    Another thing, when will OEMs start putting the USB hub at the bottom of the board facing down and not away from the board. If you have multiple cards on the board then you can get really cramped really fast when you are trying to use those.

    I'm sorely tempted to just wait another year or so till there is a board with these features and over 50% SATA 6G/s, but we'll see if that even comes out in that short of time.

    1) Some customers are asking for them. Customer demand was why a few boards started sporting floppy controllers again last summer. Legacy PCI demand is almost certainly much higher.

    2) Intel doesn't have enough PCIe lanes on the southbridge for well featured ATX boards.

    2.1) This means a bridge chip of some sort.

    2.2) PCIe devices are used to being able to count on the full 250/500MBps bandwidth.

    2.3) Legacy PCI devices are used to sharing their bandwidth (133MBps).

    2.4) 2.2 and 2.3 combined mean there's less risk of compatibility problems in filling out a few slots with legacy PCI slots.

    This is probably going to remain an issue until either:

    A) Intel increases the number of lanes they offer on their boards by a half dozen or so (bridges are also used for on board devices).

    B) Intel integrates a lot more stuff into the southbridge so it doesn't need PCIe lanes: More USB3, Sata6GB, audio, ethernet.

    C) A new version of PCIe allows sizes other than powers of two. Fitting everything on would be much easier if a board maker could fall back on just offering 13/1x or 7/7x on the main gfx slots.

    GReat to see Asrock finally stepping up with the warranty, great products.

    Something I realized by reading this roundup:

    Almost all of the current motherboards are using PCI connected Firewire chips. Even the ones that have PCIe connected firewire use TI chips, which in turn are still PCI firewire, with an internal PCI to PCIe translator.

    After some research the only native PCIe firewire controller I've found is from LSI. Does anyone else know of another solution? This is an interesting "dirty secret" that I never really paid any attention to.
