Four Z87 Express Motherboards For Three- And Four-Way SLI

Results: SiSoftware Sandra

Sandra’s CPU benchmarks also show all four motherboards essentially on-par, though its memory test shows the Z87X-UD7 TH slightly behind. With so few other optimizations to choose from, memory optimization has become the “secret sauce” of motherboard makers concerning LGA 1150 performance and memory overclocking.

That slight difference at least gives us something to look for in our real-world benchmark set, which begins on this comparison’s next page.

    Am i missing something here? I dont see the point of reviewing 3 and 4 way sli boards and not testing 3 and 4 way sli. Seems rather pointless since any average motherboard will perform well in adobe, productivity etc benches dependent on the cpu....

    This was really just about finding any board that supports Nvidia's requirements about how that third card is connected. We found some, I overclocked them, now I have enough data to pick a board for the System Builder Marathon. But that only explains why overclocking took priority!

    After spending two days per board on a "one week" article, I couldn't add more tests. The general benchmark set looks for unintended overclocking/underclocking, power and memory bandwidth issues, so you can see the performance difference attributable to each board's CPU and DRAM configuration differences. It runs from a .bat file, so it didn't add significantly to the article's completion time.

    The PLX bridge that these all share represents the "great equalizer" when it comes to CrossFire and SLI configuration, so that portion of all three boards should be identical. I understand that things that should be the same in theory are occasionally different in practice. My apologies for not having the extra 1-day per board for additional tests.

    They all use the same PLX bridge, so you would have seen a whole bunch of identical gaming results. The general benchmark set looks for unintended overclocking/underlocking, power and memory bandwidth issues, so you can see the actual performance difference. And there's still an overclocking section.

    These boards had to be tested for general performance and stability like any other boards. The PLX controller is the equalizer when it comes to games.

    I think testing 3/4 way sli would still be valid, as it doesn't always work properly, in the past there have been compatibility problems with certain gpu's/boards/firmware/controllers and certain benchmarks completely failed.

    "internally-mounted external USB 2.0 port for ReadyBoost fanatics" on the asus z87.

    Those have nothing to do with readyboost. The internal usb ports are very common on workstations and you put CAD dongles and equivalent items in them so that you can lock them inside the case and don't have to worry about some one stealing them from the outside or them taking up an outside usb port.

    I would love to see Asus Maximus VI Extreme, but it seems ASUS didn't want to give a 2nd board and prefered the Z87 WS....

    Where are the sli/cfx tests ? Non sense

    no cfx test i think the review title is misleading

    where are the sli/crossfire benchmarks and comparisons with traditional non-switched setups?

    Hey guys, we have these awesome new setups for supreme graphics pumping power! Watch it zip files like every other board!

    Those heatsinks on the Asus look like the would interfere with large CPU coolers.

    Why are they still making motherboards with PS/2 connections? Its time to move on, replace those baby's with some USB 3.0!
