The struggle between Killer and Intel as the network controller of choice is starting to drag on. This is the new variant of the Killer NIC, the E2400 claims to have better UDP performance for gaming than before, and along with its network prioritization software is often cited as a cheaper bundle than the Intel NIC on its own. But many users prefer Intel for overall performance, reliability and option set. Ultimately most people choosing this board are not going to notice much difference between the two, unless they end up with a specific issue with it, or they have a particular need for one over the other.

Because the board uses an x8/x8 configuration with an x4 from the chipset, rather than x8/x4/x4 from the CPU directly, two-way SLI should work at all times with two identical NVIDIA cards capable of doing so and even with a card in the third slot. I would expect most motherboard manufacturers to do this, although from our big motherboard preview it is clear that some are not. So a plus one for MSI here.

In The Box

We get the following:

Driver Disk
Rear IO Shield
Four SATA Cables
One Flexi SLI bridge
MSI Door Hanger
MSI Badge
XSplit License

To what extent should a gaming product have gaming paraphernalia in it? The M7 has a door hanger (which seems aimed at a particular age bracket still in education), an MSI badge (which was pilfered by my intern during testing for the back of his smartphone), and a short term XSplit license for game broadcasting. Non gamers will find the contents rather dull for $230 - other motherboards in this price range will also bundle in a USB 3.1 front panel, so there is that to consider.

Visual Inspection

MSI deserves some credit when it comes to actually looking at the Z170A Gaming M7 – taking it out of its box and there is a sense of polish to the product in the way it looks. The shade of red used fits in well with the black on the PCB that matches the black on the PCIe slots, SATA ports and other heatsinks. The decals are of high quality, and the pseudo-traces in red from the CPU to the DRAM make it feel a little futuristic.

On the top down view, it is clear that the socket area does not have the brash white of the Intel recommended distance motif around it, so as not to remove the aesthetic. Around the socket itself, there are four of the five fan headers within easy access – two 4-pin CPU headers to the top and right, one 4-pin SYS just above the PCIe 3.0 x1 slot and a 4-pin SYS above the 24-pin ATX power connector. The final 4-pin SYS header is at the bottom of the board.

Part of the cost of the board will have gone towards the power delivery here – as Skylake moves the voltage regulation from the CPU back onto the motherboard, there is more scope to customize the power delivery that feeds into the processor. Technically the CPU can run on as little as four power phases (or three for the daring), but there will be a number of 8-12 or 16+ in the product stacks. Here MSI uses a 12 phase design with their Titanium capacitors, for example.

Down the right hand side is a HotKey switch, used for resetting MSI’s HotKey functionality. Below the power connector is a USB 3.0 header with red inside, indicating its fast charging capabilities. Below this is another USB 3.0 header but at the same angle as the SATA ports as to not interfere with a PCIe card that might be installed. The SATA ports are split between a block of two and a block of four, with that four part of the two SATA Express ports but can also be used purely as just SATA ports.

Along the bottom are the power and reset buttons, along with the Game BOOST dial. As noted in the overclocking section, this dial goes up to 11. Beside this there is a slow mode switch, the BIOS Flashback button, two USB 2.0 headers, the front panel header, a fan header, the TPM header and the two digit debug display. So it is interesting that the front panel header is so far along the bottom of the board – in most cases, it is better to find it closer to the SATA ports.

The PCIe slots for GPUs are clearly marked with their protective shielding. The purpose behind this shielding is to increase the rigidity of the plastic PCIe connector. According to the motherboard companies who deal with returns, the PCIe connectors can be bent when large video cards are subject to excess forces (imagine shipping a PC with the cards installed). The shielding is designed to help that in some respects as some graphics cards move close to (and beyond) the 1kg mark, especially if large copper water cooling plates are attached. It amounts to a fix for a ‘minor’ issue, though it would be interesting to see actual force diagrams and videos relating to how this protection works, given that it is fixed only to several small points on the PCB.

On the left hand side of the board is the audio solution, an upgraded Realtek ALC1150 audio package that we commonly see on motherboards around this price point. This means an electromagnetic interference shield, filter caps and PCB separation between digital and analog signals. For MSI it also involves enhanced corrosion protection of the rear IO audio ports.  Near to the audio codec shield is a shield covering the gaming network controller, the Killer E2400. It surprises me that this controller has a shield, when in previous generations of the Killer NIC one is not needed. Quite apart from which, I’m unsure as to what benefits a shielded NIC would have, and we would have to see if it is similar to other motherboards indicating an issue with the NIC or if this is just an MSI design choice.

The rear panel for the Gaming M7 consists of a combination PS/2 port, two USB 2.0 ports beneath this, a ClearCMOS button, a third USB 2.0 port but is at right angles and used for MSI’s overclocking/monitoring software to a smartphone/tablet app, DisplayPort, dual HDMI 1.4b, the Killer network port, two USB 3.0 at 5 Gbps (in red), a USB 3.1-A at 10 Gbps and a USB 3.1-C at 10 Gbps. Finally we have the audio ports.

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, the MSI Z170A Gaming M7, on our testing BIOS v142, MCT was enabled by default. Also, the FCLK 10x ratio was not present in the BIOS tested at the time of testing.

    Thanks for the review! Any chance of an article looking at using two PCI-E 3.0 x4 M.2 SSDs in raid using Intel RST? SM951s for preference ;)
  • drtechno - Thursday, October 1, 2015 - link

    Byrn -- In short, you CAN'T. The MSI boards (all of them) do not support BOTH M.2 slots running in PCI-E x4 mode. If you plug in two M.2 drives, the second slot drops to SATA mode. It says it right there on MSI's web site.

    I don't know why this review (and many other reviews like it) don't point out that most of the boards with dual M.2 slots do NOT support dual PCI-E x4 mode. The second slot drops to SATA in almost all the boards.

    The only board I have come across that supports dual PCI-E x4 modes on M.2 is the Gigabyte boards.
  • Byrn - Friday, October 2, 2015 - link

    drtechno - Huh, thanks for the heads up. Totally missed that on the detailed spec. Only MSI board this doesn't seem to be the case for is the Z170A xpower gaming titanium edition, which doesn't have this excluded on the spec.

    That said, all the more reason for an article or even a brief piece on the subject? I can't be the only one looking at multiple M.2 slots for PCI-E SSDs (RAID or not) and it would be good to at least have this pointed out...

    Looks like I'm buying Gigabyte then (not that MSI was looking good with Nahimic and Killer even before this...)
  • LoganPowell - Friday, November 27, 2015 - link

    Too bad that the MSI z170a gaming M7 is not very popular if you look at consumer based reviews (such as which is my favorite).
  • xthetenth - Monday, September 21, 2015 - link

    What is it with MSI trying to sell products by paying to attach negatives to their products? First Killer, which is working its way up to debatable and now Nahimic, which is outright bad.
  • Flunk - Monday, September 21, 2015 - link

    I'd argue that Killer has worked it's way down from debatable to useless and are trending downward. Before they were bought out Killer's nics were at least interesting with their hardware implementation of features that other brands do in software. Now they're 100% marketing.

    Nahimic is at least optional.
  • Impulses - Monday, September 21, 2015 - link

    Little to no value + extra potential hassles galore, definitely a downside in my book.
  • DanNeely - Monday, September 21, 2015 - link

    The problem is that it takes a few years for stuff like killer going down the toilet to work it's way from we enthusiasts to the sheeple who pick their board based on the logos and pictures on the box.
  • notR1CH - Tuesday, September 22, 2015 - link

    They're actually worse than the Realtek or Intel NICs because you're forced to use Killer's awful drivers. Very disappointed to see MSI yet again buying into this gaming marketing dribble from Killer and making another don't-buy board.
  • PPalmgren - Monday, September 21, 2015 - link

    Speaking of bad onboard sound, I may be having buyer's remorse at the moment. I went with the Asus Maximus VIII Gene on my build and have been having trouble diagnosing system hangs for about a week since I built it. I think it may be ASUS' onboard sound solution. I tried closing out their Sonic Suite and ROG EQ stuff and it breaks sound in many applications, so I'm starting to worry that I'm SOL
