MSI Z170A Gaming M7 Conclusion

Of the motherboards we received for review before the launch of Skylake, we had a reasonable mix of the regular price bands, from $160 to $250, and even up at the top for $500. These more mid-range price bands are typically where most motherboard manufacturers duke it out for sales, despite the fact that the bulk of sales is usually below this. At $160-$300, it allows the manufacturers to stretch in terms of technical prowess and their view of the market.

The MSI Z170A Gaming M7 comes in at $230, arguably at the higher end of most people's budgets but enough to satisfy the enthusiast space. From a hardware perspective, the M7 focuses on its key marketing points towards gaming, such as the Killer E2400 network port, Nahimic audio software, easy overclocking functionality and new easier to use BIOS interface for new users.  Other features come in as well - metallic guards to strengthen the PCIe slots when heavy graphics cards are in place, USB 10Gbps ports in 3.1-A and 3.1-C, dual M.2 slots that run at PCIe 3.0 x4 mode and SATAe connectivity.

Negative points off the bat start with the Nahimic audio software. It completely cuts out the EQ, even when you uninstall it - a big no-no from anyone who genuinely likes to customize their sound quality. Most of the features the Nahimic software provides are essentially EQ adjustments anyway, leaving me to wonder why MSI is paying through the nose for license fees (and passing that cost to the buyer) rather than doing basic modifications to the Realtek software that comes free with the codec. Additional to this, even with the Nahimic implementation disabled, audio performance in our tests did not set the world alight. Power consumption at load (at stock) was a little high as a result of the motherboard applying more voltage to the processor than expected. This might be related to the MultiCore Enhancement used.

Also to note is that our overclock testing, perhaps due to the beta BIOS versions we were using at the time, seem to be behind some other products. But because a review is a snapshot in time, we perhaps shouldn't hold it against the board unless other MSI motherboards in the future perform similarly. Also, at $230, one might have expected either a second network port (wireless or wired) or at least an Intel network controller. For most users that care about the network controller, Killer comes across more of a marketing checkbox compared to the control normally attributed to the Intel network ports.

Where the MSI Z170A Gaming M7 wins comes down to our BIOS implementing MultiCore Enhancement by default, resulting in a better stock performance. As a result, all our base processor tests but the MSI ahead. The new EZ mode in the BIOS is a good design worth playing around with, as well as MSI having the best driver/software update software for motherboards we've ever seen. This becomes more useful given that later BIOSes should become available as time goes on.

At the end of the day, MSI might struggle to sell this for $230 MSRP. The market will have other motherboards to play with that offer more features with less marketing buzz (Killer/Nahimic) at the same price or lower, perhaps pushing users towards the Gaming M5 and below. There are some take home positives, such as the new easy overclock tool and the drive towards catering for their intended market, though pushing it in to a higher than expected price band may drop it off some build lists sooner than MSI would have hoped for. As we test more motherboards, we should be able to develop a taste for the ecosystem as a whole and understand how each of the motherboard manufacturers are approaching the Skylake platform.

    The chipset has been upgraded to pci express 3.0 with 20 lanes. the cpu still has it's own dedicated 16x link separate from the 20 lanes to the chipset. the cpu's latency is greatly reduced vs chipset, so that's why graphics cards use it.

    all the new M.2 drives use the chipset bandwidth now at x4 PCI E 3.0, leaving 16X for more M.2's, Sata, USB, Etc..

    You have 16 3.0 lanes on the CPU and up to 20 3.0 lanes on the south bridge. Up to is a very important qualifier; most boards will have significantly fewer available. What the SB has is 26 high speed IO ports that can be used for a sata 3 port, a USB3 port, a PCIe 3.0 lane, or be bundled together for an sata express or m.2 SSD controller. Take all 6 sata ports, all 10 USB3 ports from the chipset and you've only got 10 lanes left for SSD connections or PCIe slots. The maximum configuration for SB lanes is PCIe x4; because the SB itself only has a 4 lane equivalent uplink to the CPU.

    Thanks @Morawka and @DanNeely,
    Am I right in thinking that in this case, if Cross Fire is consuming the 16x lanes from the CPU, then the SSD can get it's x4 PCI-E 3.0 lanes from the PCH (assuming sufficent free lanes which this should have)?
  • DanNeely - Tuesday, September 22, 2015 - link

    yes.
  • K_Space - Tuesday, September 22, 2015 - link

    Much obliged.

    Latency isn't the issue, it's bandwidth. In theory you can use the extra lanes as you describe, but only if the motherboard wires up the lanes correctly. Check the motherboard manual for supported configurations.

    Awesome review! Im excited to see more lga1151 motherboard reviews and please please please do a lag 1151 mini itx motherboard review!

    Great timing! I just ordered this board two days ago (and lucked out getting a i7 6700k). I can't wait now to start my build and try it out.

    I wonder why MSI removed Sound Blaster Cinema and went with this Nahimic audio software? Also I found the Killer Network worked fine if you removed the Qualcomm Suite (that automatically installs with Killer), and installed the plain Killer NIC drivers. I've been using it over a year now that way with not a single prob. Always had good luck with MSI products, so here's hoping that streak continues. It's a good looking board too.

    Ian, slightly off topic. According to MSI's website the H170-M3 supports unbuffered ECC memory. Is this an error on MSI's part? Any indication if:

    * This board supports ECC / certain Z170A boards could support ECC with a Xeon (or whatever other CPUs in ARK are listed as having ECC support)?
    * H170-M3 just has some extra traces that the Z170-M7 does not? Is there any dependence on chipset for ECC support with an on die "northbridge"?

    people still buy this expensive crap? overclocking? what a huge was of time and money. this article is for the 1% . no one cares anymore about high end "gaming" crap. No one cares about 4k. It's all hype for the industry. you want to stare at tiny icons, text you cant read, and horrible fps so badly ?! and you want to PAY other people money to do this. blows my mind
