Seven Sub-$160 Z77 Express Motherboards, Reviewed

Z77H2-A2X Deluxe UEFI

ECS' M.I.B. X menu opens to reveal important voltage settings, including CPU core and Vdroop. Setting Vdroop to Disabled allows the system to keep voltage stable under increased load.

With Vdroop disabled, we found that our CPU climbed from 1.15 V at idle to 1.25 V under load using the Z77H2-A2X Deluxe’s 1.15 V setting. That voltage got our processor to a stable 4.69 GHz with all four cores fully taxed.

A mere 1.25 V isn’t enough to push 4.7 GHz from our chip on most motherboards, yet ECS still supported the 47x multiplier. An under-spec base clock of 99.7 MHz at the 100 MHz setting explains this discrepancy.

The Z77H2-A2X Deluxe supports Intel’s XMP technology to ease the overclocking of most DDR3 memory modules. Fortunately, the XMP timings stick when switching from XMP to Manual mode, and SPD timings stick when switching from full-auto to Manual mode.. Thus, we were able to keep our memory’s complete timing configuration while playing with its multipliers. Biostar could learn something from this.

ECS appears to learn from all of its competitors, expanding its overclocking profile storage to support up to eight custom UEFI configurations.

    LAN performance .. ISC performance ... USB 3 .. well that's it then.

    Tom's Hardware has several controller comparisons, and publishes new ones frequently. So unless you think one of the boards has a broken controller, wysiwyg.

    The things that actually get screwed-up are typically related to the clock generator, multiplier control, memory timings and power options.

    I would place the ASRock and Gigabyte on the top as well : )

    Nice review.

    I always appreciate your Articles! :) I know how much work you do to get them done.

    You're kidding - Biostar. I guess this article is not about the 'Best Sub-$160 Z77' MOBO's but about the best manufacturers sent you. The cheapest MOBO I recommend for the SB/IB (K) is the ASUS P8Z77-V which pops your 'unique' budget cap depending where you shop; found it here for $159.99 - http://www.gadgetneeds.net/asus-p8z77-v-atx-intel-motherboard/

    Interesting you didn't get an ASUS P8Z77-V LK ~$120 which offers SLI. The ASRock Z77 Extreme4 and Gigabyte Z77X-D3H for the price aren't bad.

    There's NO WAY I'm recommending Biostar in the forum, folks and myself would thing I've lost my mind.

    It would be nice to see the CPU voltage for every board when overclocking.

    No peripherals performance tests? Those are the only tests that differentiate those motherboards from each other.

    Would really like to see how the UD3X Atheros Ethernet controller fares against the Intel and broadcom ones.

    I'll let the integrated controller guy know you'd like to see those parts compared :)

    I would have liked to see the Asus P8Z77V-LK version instead of the LX since it is better equipped.

    It's also mentioned in the article. It was over $160 (at $165) when the comparison was set up.

    Why are there no DCP latency tests ? These differentiate the motherboards
    This is what differentiates them performance wise.

    Wow, Biostar...? I wonder what the longevity of that board is...

    It's hard to tell, but the last Biostar board I had in a system lasted 12 years before it got dismantled for its entire processor selection being too slow.

    Nice to see a Mobo review where the charts are not all identical bars lol. It has been a long time sense the stock performance has had much of any variance between brands, and we are getting much more feature variety as well. I thought as more and more parts became integrated into the CPU that the bars would become more and more similar, and mainstream features would become more and more homogeneous.

    Also, I love the True Studio Pro software, if you are running digital audio it really makes any idea of a dedicated sound card a thing of the past. Every computer I build now either has True Studio Pro with the mobo, or I purchase the MB2 software suite, it makes such a difference if using headphones or quality speakers, and much less buggy that Creative's sound cards and driver issues that we all know and love.

    On-motherboard start buttons are a useless feature. Anyone who could actually use it should know they can just short across the power switch header using any piece of metal.

    At this point SATA 6GB, USB 3 and PCI-e 3.o should be a standered and not a side option.

    As good as Asus motherboards are - why do they include such poorly made I/O brackets? Even Biostar and ECS include ones that are better made than Asus does.

    Another comment about why the P8Z77V-LK board was not reviewed. I own this board now after a total disaster with one of the boards you awarded so why is it missing? The ASUS P8Z77V-LK was priced at $149.99 when I purchased it and is now $139.99 with a rebate down to $119.99 after a quick check this morning. Based on your comments about the Biostar and ASRock boards having additional features like SLI/CF or additional USB 3 ports it is hard to understand why this board was not reviewed. The P8Z77V-LE is priced at $165 not the LK board. As to the 4-dimm testing, did you try the DDR3-2666 ratio or is the test overclocking the 2400 ratio?

    Because it was priced at $165 two months ago when the invitations went out. End of story.
