Test Bed and Setup

Readers of our motherboard review section will have noted the trend in modern motherboards to implement a form of MultiCore Enhancement / Acceleration / Turbo (read our report here) on their motherboards. This does several things, including better benchmark results at stock settings (not entirely needed if overclocking is an end-user goal) at the expense of heat and temperature. It also gives in essence an automatic overclock which may be against what the user wants. Our testing methodology is ‘out-of-the-box’, with the latest public BIOS installed and XMP enabled, and thus subject to the whims of this feature. It is ultimately up to the motherboard manufacturer to take this risk – and manufacturers taking risks in the setup is something they do on every product (think C-state settings, USB priority, DPC Latency / monitoring priority, overriding memory sub-timings at JEDEC). Processor speed change is part of that risk, and ultimately if no overclocking is planned, some motherboards will affect how fast that shiny new processor goes and can be an important factor in the system build.

For reference, both the MSI Z270 SLI Plus and the ASRock Z270 Killer SLI had multi-core acceleration enabled by default. We tested the MSI Z270 SLI Plus with the 1.4 BIOS and the ASRock Z270 Killer SLI with the 2.00 BIOS.

    Nice article, more mainstream reviews are always appreciated.

    people need to realize that z270 and intel are still a great buy for regular users. its not a bad investment. i just prey that 6core comes in time to consumers.

    Aside from the fact it is highly unlikely it will accept more than a single generation of processors.
  • Cygni - Monday, May 1, 2017 - link

    Seems pretty likely that Coffee Lake is intended to be compatible with Z270.

    That would be a new one for intel ;) If that happens, I guess "competition". For years now, intel has been artificially limiting chipset compatibility to squeeze extra chipset sales by obstructing upgrades.

    Thats not what I've been reading....New Intel Coffee Lake 6 Core CPU's will need the 300 Series Chipset which means....New Motherboard !

    The Inter Coffee Lake 6 Core CPU's will need the 300 Series Chipsets which means...New Motherboard !

    Totally agree, more reviews of the volume pieces would benefit far more readers. I won't be buying either of these but at least now I know why.

    It's incredible that they can market something so complex, with so many precision parts, materials, and process steps - not to mention all the ICs - for a delivered price of $140! These are the benefits to us of mass production and sadly low foreign wages. Given that I'd use such a mobo heavily for hours every day, for years, I'd willingly pay more if I knew the workers got more.

    Nice write up Thank You. I just looked the MSI board up at Memory Express in Canada it goes for $209.99 CAD which sounds about right after exchange rate.
