Four Z77-Based Mini-ITX Motherboards, Reviewed

Yes, you can get all of the functionality enabled by Intel's Z77 Express chipset in a tiny mini-ITX form factor! We round up four motherboards that uniquely approach the gaming and media center markets with a range of features and prices. Which is best?

Z77E-ITX Firmware

Mini-ITX doesn’t leave much room for big voltage regulators, and the enclosures designed to support mini-ITX usually lack room for large CPU coolers anyway. So, we don’t expect much additional frequency from this format. On the other hand, fully unlocked multipliers are the primary reason to choose K-series processors and Z77 Express over H77. Some flexibility, at least, should be possible.

The Z77E-ITX doesn't let us down, pushing a stable 4.5 GHz through a simple multiplier change. Other options include ASRock’s pre-defined 30% and multi-level overclocks. We prefer to set our own voltage limits, though.

ASRock's Z77E-ITX had no trouble dialing in our test configuration’s DDR3-2666 XMP profile, saving us a bunch of time compared to manual memory configuration.

Though our expectations of overclocking on a mini-ITX platform are relatively modest, so are the voltage levels we're willing to apply to our CPU. The heat levels on Ivy Bridge-based processors increase far faster than attainable clock rates once you get up above 1.25 V or so. We were able to achieve our chosen voltage at the Z77E-ITX’s 1.225 V setting. A Load-Line Calibration setting of Level 5 kept that voltage nearly stable under changing loads.

We had to drop the board's XMP-defined 1.65 V setting to 1.6335 V in order to register an actual 1.65 V, as determined by a volt meter. Fortunately, the DRAM voltage regulator doesn’t need load-line calibration to remain stable.

Like most of ASRock’s enthusiast-oriented motherboards, the Z77E-ITX includes a full set of primary and secondary memory timing controls.

    Years ago, decent mITX boards were slim pickings.

  • where are the dtx mobos for those that want a gaming graphics card as well as a dedicated sound card that isnt onboard crap?

    Asus maintains a list of other technologies only found on its platform, including the ability to charge smartphones and tablets through its USB ports
    That technology is available from MSI and Asrock (and Gigabyte, but that's irrelevant in this roundup). Look up MSI i-Charger and Asrock App Charger.

    tarkheinAsus maintains a list of other technologies only found on its platform, including the ability to charge smartphones and tablets through its USB portsThat technology is available from MSI and Asrock (and Gigabyte, but that's irrelevant in this roundup). Look up MSI i-Charger and Asrock App Charger.All three companies have similar high-current charging features, but Asus extends them to non-Apple devices. The comment was originally left out due to the similarities and added later due to the differences.

    There was a big discussion between editors over whether or not the P8Z77-I Deluxe should get an award. The only award for "best features" is Tom's Hardware Approved, and that award is reserved for products that are clearly and obviously superior. The P8Z77-I Deluxe was a better board, but we had to look fairly hard to see it (it wasn't clear or obvious).

    So many variations between each board when it comes to OC......

    "We retained most of the hardware from our previous Z77 motherboard round-ups, but were not able to reach the same CPU clock speeds. A shift over to Windows 8 was our biggest change, and services crashing under that operating system appeared to limit what we could achieve compared to Windows 7."

    CrashmanLOL, welcome to Windows 8.
    How about using Windows 7? Was a reason you HAD to use 8 despite encountering issues? Is there some contractual obligation or monetary incentive to use the lastest version regardless of performance issues? Or at least test them both, it's only 4 motherboards.

    I think Mini-ITX will be the new standard size.
    It's not like the 80s/90s where you needed a full size AT/ATX motherboard with many slots for the ST-506 controller, floppy disk controller, serial port, parallel port, Sound Blaster card, VGA card, token ring card, and an extra cooling fan.

    EDIT:
    I will later get a Mini-ITX later & Silverstone case, stick in a Noctua NH-C12P & Haswell i7, and my Nv 680. That will have very high power density and worthy of being my "main" PC. (and it will OC)

    One issue I see is the PCI-E x16 slot is at the very bottom of these boards, and most video cards use two slots, requiring a larger case than one that simply supporting the motherboard based on ITX/mini-ITX dimensions. I'd be interesting in exploring the limitations of such configurations, and whether these boards are effectively limited to single slot video cards (and performance), require larger cases than is assumed, or specific case configurations.

The thought of having a spare drive on hand simply for testing O/C never even crossed my mind after hearing the "s" word.abbadon_34One issue I see is the PCI-E x16 slot is at the very bottom of these boards, and most video cards use two slots, requiring a larger case than one that simply supporting the motherboard based on ITX/mini-ITX dimensions.

Since most people don't know what DTX is, most case manufacturers have changed the label to read "Mini ITX". Still, there are a bunch of DTX cases out there caring the Mini ITX label.
