Overclocking

I was rather impressed to find both an "Extreme OC" switch along with a set of power and reset buttons onboard.


There is also a dual-digit Post display.



Overclocking is going to be highly dependent on your cooling with these CPUs, but should you have adequate cooling, the ASRock X399M Taichi is ready to push both the CPU frequency and memory speed up, with 3600 MHz memory support as claimed on the box working without any hesitation when you have the right type of memory sticks. I actually could not be more impressed with how easy it was to overclock on this platform with ASRock's X399M Taichi as it didn't prove to be much different from overclocking with Ryzen, which naturally makes sense given the similarities. I also found that I could not always rely on CPU-Z to give me the right information; you can see in the screenshot above that the voltage reported is different from that in the "stock" CPU-Z screenshot, but the multiplier hasn't changed. I did change it though, and the performance testing I did reflected those changes as did other tools, like AIDA64's CPUID tool. However, it could all be down to the version of CPU-Z I used when testing, as newer versions are out as I am typing this.
