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.

    I'm curious how Skyrim behaves with this Lucid technology, since physics and framerate are linked for whatever reason... (if you disable Skyrim's 60 fps cap and point the camera in a direction that gives you 150+ FPS for example, everything that is moveable nearby starts to rattle and fall off shelves...)
  • Xale - Sunday, April 8, 2012 - link

    Games with their own framerate limits should not be affected, as long as that limit is preserved. They already simply 'pause' internally if the machine is too fast. It might go absolutely crazy though if you do forcefully disable that mechanism.

    Am I reading that right? Z75 offers most of what even enthusiasts would want?

    So... why are there a crapton of Z77 boards in here and no Z75s?

    Z75 supports 2 way crossfire / SLI, overclocking, 6Gbps SATA, native USB3.0... these are the features all but a tiny handful of users should be interested in.

    By all rights Z75 should be the definitive chipset for the average enthusiast. Unless I'm missing something major, I hope there is significant attention paid to the Z75 chipset in reviews, because I'm failing to see why any but the most extreme users and those with money to burn would choose the Z77.

    Actually the ones with less money to burn might choose Z77 over Z75 to avoid investing in a huge SSD. The difference between chipset prices are usually small (what the motherboard manufacturer makes out of this is another question entirely).
  • GreenEnergy - Sunday, April 8, 2012 - link

    I find SSD caching to be some desperate dinosaur attempt. Mainly fueled by HD makers. Hybrid HDs are in the same basket. And yes, pick one, Z77 or Z75. The other one makes no sense.

    Z77, Z75 and H77 chipsets are priced at US$48, US$40 and US$43.

    If SRT basicly cost 8$. Then its time for it to go away as the stillborn tech it is.
  • Zoomer - Tuesday, April 10, 2012 - link

    The difference is mainly software and development, and should go away. SSD caching is a great idea that, imo, should optimally be on the filesystem level, not on the block level.

    *Looks at OS / filesys developers* (ZFS has some of it)

    And oh, I expect lower end derivatives to come out eventually.

    I was really excited about this motherboard - was kind of disappointed to see it is not part of this roundup. But I guess there will be other tests. Thanks for the preview - I look forward to the benchmarks, particularly if asus' memory technology works well, and if memory bandwidth plays more of a role on Ivy Bridge.
  • Articuno - Sunday, April 8, 2012 - link

    Things like overclocking being restricted to specific chipsets is really disappointing. AM3+ boards are generally cheaper than equivalent Intel boards and they don't lock features like this.
  • MrSpadge - Sunday, April 8, 2012 - link

    I suppose it's being done to make power delivery cheaper on these boards. Personally I don't like it either.
  • GreenEnergy - Sunday, April 8, 2012 - link

    I think you should visit Newegg. LGA1155 and AM3+ boards are just as cheap. And CPU wise...its just a disaster for AMD.
