The M7 ACK is a solid all-around motherboard. There are a ton of motherboards on the market for Intel's latest HEDT platform built on the X299 PCH for use with Skylake X and Kaby Lake X processors. MSI's X299 Gaming M7 ACK is just one of the many. We definitely recommend going for an Intel Core i7-7800X minimum with this setup, to gain access to the additional PCIe lanes and avoid memory confusion, but if you’ve got the cash, it’s a damn fine mobo.
Overclocking was fairly painless with the X299 Gaming M7 ACK and allowed me to reach up over 4.6GHz on the Core i9 7900X and step over the 5GHz boundary on the Core i7 7740X. The key to overclocking on eight-core and higher chips from Intel is to keep the voltage as low as possible to minimize the thermals.
The MSI X299 Gaming M7 ACK is a fully-featured ATX form factor motherboard with an impressive list of extras. Looking at the specifications, we see that it supports LGA socket 2066 Intel i9, i7 and i5 processors on the X299 chipset.
A Closer Look
The first thing that catches the eye in the PCIe area is the extra large PCH heatsink. This is MSI’s M.2 Shield FROZR which is intended to protect your M.2 drives from accidental damage as well as operate as a thermal solution/heatsink. The shield is held closed with two small screws. Removing these and opening the shield on its hinge reveals the two M.2 slots for additional drives. The back of the arms have thermal tape affixed to them (see picture below) which acts as an interface between the M.2 drives and the arms of the shield. This helps dissipate some of the heat these drives can produce.
The motherboard is mainly targeting gamers, but it's also targeted towards modders and power users. It offers the latest features such as RGB LEDs, M.2, and USB 3.1, but it also offers a lot regarding aesthetics and even some overclocking features.
