I have new build using the Phantom Gaming 6 with a Ryzen Threadripper 2920X CPU. My issue is I can only get the turbo boost function to work when the CPU clock rate is set the 3.5 GHz. When I go into the bios and manually set the CPU voltage and CPU clock, any clock setting above 3.5 GHz locks all of the cores to that frequency even though the turbo boost settings in the bios as the same as work when the CPU clock is set to 3.5 GHz. How can I overclock the CPU (e.g. to 3.9 GHz) and still get turbo boost to work? |

The simple overclocking disables turbo clocks by default. I don't remember off hand as I don't overclock my 2950x but I believe the settings you are looking for are under the advanced tab, Zen Options. I find precision boost yields near identical performance to my best manual overclock attempts and more importantly, at lower voltages. PBO works very well on second gen Threadripper. I spent days fine tuning and tweaking when I built the system only to discover that PBO worked better and was less problematic (at least for my workloads)....... Now if you need higher all core clocks than PBO sets you will need to look under the advanced settings and manually set your multipliers there: 2 cores = XX 4 cores = XX etc. -------------
