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. Short-term, a quality AIO will get the job done, but for the long-term you will need to go with a custom water setup. Even so, I found the motherboard was easy to overclock with both manual tuning and by using the EZ OC button to dial up the preset I wanted. MSI uses its Military Class 6 build components to ensure you have a stable long lasting power circuit that should prove to be fine as long as you do not abuse it. Much like everything else while overclocking, you pay your money you take your chances. I find manual tuning to be the way to the highest overclock and MSI's Click BIOS continues to get more granular in the quest to deliver performance while not going off the deep end.
