What happens when a vendor adds 802.11ac to Killer networking? You get an ACK - specifically, the MSI X299 Gaming M7 ACK. This motherboard includes 3-way SLI and Crossfire support, dual M.2 slots with a unique heatsink design attached to the chipset, both front and rear USB 3.1 (10 Gbps) ports, dual Realtek audio chips, Killer based networking, and plenty of RGB LEDs to light up the case.
MSI X299 Gaming M7 ACK Overview
With the X299 platform, users tend to drop into one of two categories: the all or the nothing. A user investing in X299 is either trying to get everything, every feature, with multiple graphics cards and displays and lots of memory, or they are trying to get the high-end on the cheap. I remember the days when investing in X58 to get a Core i7-920 and overclocking it was seen as the height of aiming at performance, compared to investing in a Core i7-800 series platform. Back then, X58 was a stepping stone into HEDT. But here, the MSI X299 Gaming M7 ACK, or M7 ACK for short, is clearly aimed at users who want it all: more cores, more memory, more graphics cards, more storage, more network connectivity, and most importantly, more LEDs. If you wanted to light up the night, this is one motherboard that can certainly do that for you.

Aside from features and LEDs, there is one consistent metric in all motherboard reviews. Our performance results placed the M7 ACK right in the middle of the pack, performing well overall. The form of Multi-Core Enhancement it has runs the benchmarks in the 3.6 GHz range, as do the majority of other motherboards tested. The main system performance win was the fact that it was the fastest MSI board to boot that we have tested so far. But users investing in this system should look into the overclocking.
Manually overclocking our Core i9-7900X was met with little fanfare, as this board happily took our i9-7900X CPU to 4.6 GHz before running into our temperature limit. Using the automated OC tool, Game Boost, was a different story. We were only able to reach the 2nd boost level before the CPU was throttling due to the voltage causing temperatures to be too high for the settings. Through it all, the smaller heatsink covering the VRMs did a good job keeping temperatures to an acceptable level during our extended stress testing peaking at 75C while overclocked to 4.5 GHz.
The M7 ACK allows users to have all the options for storage connectivity. There are eight SATA ports along with two M.2 slots. These slots are both covered by the unique hinged heatsink attached to the chipset heatsink. Both M.2 slots support PCIe and SATA modules, and share bandwidth with the U.2 port and SATA ports.
The board comes with four full-length PCIe slots in positions 1, 3, 4, and 6. Those slots are all connected through the CPU and intended for video cards. PCIe slots 2 and 5, both PCIe 3.0 x1, are connected through the chipset. For connectivity, there is a total of four USB 3.0 ports (three managed by ASMedia 1074, one by the chipset), three USB 2.0 ports (chipset), and two USB 3.1 ports (Type-A and Type-C, ASMedia 3142) on the back panel. Internally there are additional headers for both USB 3.0/USB3.1 as well as two USB 2.0 headers.
For networking, MSI chose to go with an all Killer-solution here. The board uses Rivet Networks latest Killer E2500 NIC for wired duty and the Killer Wireless-AC 1535 module for wireless, which comes pre-installed in the M2 (Key E) slot. The 802.11ac module supports Bluetooth 4.1 and speeds up to 867 Mbps. The networking is built into the name of the motherboard - Killer networking and 802.11ac gives 'AC' and 'K', for ACK.
Pricing for the MSI X299 Gaming M7 ACK is $390 at Newegg and $365 (from $420) at Amazon. This price point puts it in some decent company in the the $350-$400 range including the ASRock Fatal1ty X299 Professional Gaming i9 currently listed at $390 (from $399), the ASUS ROG Strix X299-XE Gaming at $370, and the GIGABYTE X299 AORUS Ultra Gaming Pro priced at $350. If U.2 is needed, the MSI board is the hands down choice, otherwise, users will need to filter through faetures they need and want as well as consider looks and price.
MSI X299 Strategy
MSI brings a current total of eleven X299 boards to choose from: the MSI X299 XPower Gaming AC holds the flagship title and makes its home in the Enthusiast Gaming segment along with the X299 Gaming M7 ACK. There are a total of three boards in the Performance Gaming hierarchy in the X299 Gaming Pro Carbon AC, Gaming Pro Carbon, and X299M Gaming Pro Carbon AC (mATX). The Arsenal line carries the three Tomahawk boards, the X299 Tomahawk, the X299 Tomahawk Arctic and the X299 Tomahawk AC, while the Pro lineup for professionals has three motherboards; X299 SLI Plus, X299 Raider, and X299M-A Pro.

X299 Motherboard Review Notice
If you’ve been following the minutiae of the saga of X299 motherboards, you might have heard some issues regarding power delivery, overclocking, and the ability to cool these processors down given the power consumption. In a nutshell, it comes down to this:
- Skylake-X consumes a lot of power at peak (150W+),
- The thermal interface inside the CPU doesn’t do much requiring a powerful CPU cooler,
- Some motherboard vendors apply Multi-Core Turbo which raises the power consumption and voltage, exacerbating the issue
- The VRMs have to deal with more power, and due to losses, raise in temperature
- Some motherboards do not have sufficient VRM cooling without an active cooler
- This causes the CPU to declock or hit thermal power states as to not degrade components
- This causes a performance drop, and overclocked systems are affected even more than usual
There has been some excellent work done by Igor Wallossek over at Tom’s Hardware, with thermal probes, thermal cameras, and performance analysis. The bottom line is that motherboard vendors need to be careful when it comes to default settings (if MCT is enabled by default) and provide sufficient VRM cooling in all scenarios – either larger and heavier heatsinks or moving back to active cooling.

CheapSushi - Monday, March 5, 2018 - linkHating on Killer NICs has become a dumb meme. And guess what? The newer chips are often actual Intel. https://www.anandtech.com/show/12178/its-actually-...
mkaibear - Monday, March 5, 2018 - linkI choose to "hate on them" because their USP is that they make the board somehow faster in online gaming, yet every independent test shows them to not do that - plus they increase the BOM significantly for no real benefit.
The Killer chips on this board aren't Intel btw.
(There's a bit of personal history involved too - I've had several machines with Killer networking chips and they've all had significant driver problems)
nevcairiel - Tuesday, March 6, 2018 - linkReputation is hard to fix, and if its just an Intel chip, whats the premium you get from those exactly?
Personally I'll always prefer a board with plain Intel NICs, and WiFi on a PC board is meaningless to me anyway (the one you linked is Killer WiFi, not Ethernet)
Flunk - Tuesday, March 6, 2018 - linkStill a waste of money on that BoM and you get the annoying Killer app.
Something being mentioned in a meme (and all memes are dumb), doesn't make it untrue.
Pork@III - Monday, March 5, 2018 - linkRGB LED give you +20 armor :D
69369369 - Monday, March 5, 2018 - linkRGB LED give me erection :D
PeachNCream - Monday, March 5, 2018 - linkYet another x299 motherboard review of yet another yawn-fest RGB and Killer NIC been there and done that also ran gaming product. What's missing here is a non-standard approach and reviews up and down the product stacks of various vendors. This is what happens when you rely exclusively on what companies are willing to send you for free in the mail. They spoon feed journalists a series of gaming-class products with stupid features so we readers rarely see any decent analysis on the wider cost ranges of boards out there because poor people like Joe end up wasting their time messing with boards that only a small number of people purchase. The same thing happens with phones, processors, GPUs, and so forth.
I'm sorry if this sounds rude, but it's frustrating and makes this Peach not overly fond of tech journalism at large. Add that to the years of touting Rivet Networks Killer products without ever justifying it with a benchmark or two that demonstrates there's a reason for the boosting writers have to do and it the whole site feels disappointing even if there's value in other articles. I mean there's not even a networking benchmark at all so we can't even infer added value by comparing a Killer whatever to vanilla Intel using results elsewhere. If the opening shots of the article are going to cite networking connectivity, why isn't that given even a cursory examination in the subsequent pages? What's going on Anandtech?
Ian Cutress - Monday, March 5, 2018 - linkNetworking is extremely hard to get right as a test. It's easy to run it at peak speeds, but networks are rarely used in that instance.
As for the marked benefit of Killer, it comes down to something not overly benchmarkable: online performance with concurrent data streams. If you are gaming, plus downloading, plus streaming, plus watching youtube on another monitor etc, the priority thing does its job. Most solutions are purely software-based - Killer's stuff is actually in hardware: for what isn't whitelisted, the packet analytics can work to decipher what sort of data is coming through, and from where: video, audio, direct downloads, torrents, and such all have detectable ways that the packet data is processed. Different codecs can have different packet profiles, and the Killer stuff is designed to detect them and adjust the return priority as appropriate. A packet will get tagged with a priority and sit in the incoming/outgoing queues, sometimes bypassing the queue altogether. Without deep networking knowledge, and hooks into the Killer hardware requirements, this is super difficult to benchmark. Unless you want a non-repeatable test with an uninterpretable result, or a repeatable test with no real-world value.
I'd love to get some proper Killer testing in, combined with an interview with the CEO and CTO. I can just tell from the comments that it would be a piece that people come just to comment negatively, rather than read, because of the Killer experience in the past. It's a topic I've discussed with the Killer team on numerous occasions.
As for the glut of X299 reviews, we have different reviewers for each chipset/socket: Joe on X299/Z370, Gavin on AM4, Tracy on TR4. Tracy has been waylayed due to lack of hardware, Gavin is new so getting up to speed, and Joe is powering through. Joe is only just moving to Z370 as well, and has a few of those already half-done.
timecop1818 - Monday, March 5, 2018 - link> I'd love to get some proper Killer testing in, combined with an interview with the CEO and CTO.
Why not actually do that? I would come to read it and laugh at the graphs showing killer not excelling at anything in particular.
I guess the reason there's not a killer nic review out there is because it would show how embarrassingly stupid the whole thing is, providing zero advantage at additional cost and actually making things worse by shitty drivers. I don't buy that QoS bullshit, Ian, you're not stupid, if some idiot is shittorenting on ADSL no amount of qos/killer is gonna make a difference when upstream is saturated. Most "gamers" that this is targeted at will either have appropriate broadband connection or be smart enough not to use bandwidth during their gaming sessions. Also with things like NAS etc having torrent/etc clients I just don't see many people using their primary gaming rig for downloading crap (or using shittorrent at all, i know i haven't for years).
I was looking at buying new XPS13 from Dell, saw it had soldered (not socket) killer WiFi, passed it for another brand.
