MSI Z170A Gaming M9 ACK Motherboard Review: Sharp Dressed, Feature Packed

Z170A Gaming M9 ACK BIOS & Overclocking

MSI has updated their UEFI BIOS with its latest motherboards and given it a new name -- “Click BIOS 5”. It blankets the interface in a super clean, intuitive UI where surprisingly, the Advanced Mode is not only comprehensive, but as easy to navigate as EZ Mode in our opinion. As to be expected, however, there are many more tuning options in the Advanced Mode to boost CPU and memory performance, tweak thermals and more. Yet, the entire BIOS benefits from a high resolution scalable design where all text and fonts are prominent and clean for easy reading. The Advanced Mode also features a simplified labeling structure for each of the major components on, or installed in, the MSI Z170A Gaming M9 ACK motherboard.

Here’s the main or first page users will come to when entering the EZ Mode of the new Click BIOS 5 environment. It’s clean and well-labeled with a central list connecting you to all the BIOS basics as well as the OC options.

At the upper left corner of both the EZ and Advanced Modes, users can access a digital version of the Game Boost dial (physical version on mobo) offering 7-different settings or speed steps to instantly take your Skylake CPU all the way to 5.0GHz -- If it'll clock that high, of course.

More demanding overclockers will switch over to the Advanced Mode. There, virtually every aspect of the motherboard can be tweaked and tuned; voltage, various storage functions and configurations, fan controls, exhaustive memory tuning features, hardware monitoring, M-Flash and more await eager enthusiasts.

As for overclocking, the Gaming M9 ACK is very accommodating. You can OC right on the board with the physical Game Boost knob, in the BIOS either in EZ or Advanced Modes, or at the desktop using the included utility suite. Using a simple ratio-based overclock, we dialed in 100 x 46 to get a rock-solid 4600MHz on our Core i7-6700K. With the XMP memory profile enabled our 16GB kit of Corsair DDR4 memory went from its stock 2133MHz to the max supported 2666MHz speeds. More is obtainable and we even hit 4.8Ghz with a bit more testing. Yet PCMark 8 shot the temps to 89C in the first few seconds. We were able to keep temps below 82C while playing a few games, however, we'd advise against a configuration like this without adequate cooling and spending more time with the wealth of tuning options.

At our 4.6GHz OC, the system flew through our benches without a single issue. We’re confident with additional cooling and effort the board would have more left in the tank.
