The SSD Review published a review on the ASRock Z370 Taichi Build Makes 5Ghz OC Simple
A quote from the article:
Our combination of the ASRock Z370 Taichi, 8th Gen Intel chip and Intel optane provided for the fastest and most powerfull build to date! Not only do we demonstrate how to hit and use a solid 5GHz in two easy steps, but also, our video demonstration validates the fastest system startup and shut down we have seen yet in a PC. It also validates our 5GHz clock speed.ASRock Z370 Taichi Build Makes 5Ghz OC Simple @ The SSD Review
