Overclocking on 5000 series chips is really do different than 3000 series chips. We will go over some basic overclocking using AMD’s Ryzen Master software, which is quite easy to use.
The Ryzen 5 5900X has a base clock of 3.7 GHz and boosts up to 4.8 GHz. Now that boost is only on 1-2 cores. By overclocking we can set all cores to run at the same speed all of the time. This will give us better performance, especially in multi-core workloads.
Using the AMD Ryzen Master software we set a custom profile with the settings that we wanted.
When it comes to overclocking I would suggest starting at the base clock of your processor and moving up in small steps. So for the Ryzen 9 5900X it would be 3700, 3800, 3900, etc. You are likely going to have to adjust your voltage as well. A good starting point is 1.35-1.40V Vcore. Each time you overclock load into Windows and run a stability test, we use AIDA64 and CINEBENCH, but any CPU-focused benchmarking program would work. When running the stability test / benchmark be sure to keep an eye on your temperatures as well. If your system does not boot up try upping your Vcore. If that does not help you could try settings your load line calibration higher.
After much testing we were able to get our Ryzen 9 5900X running at 4.6 GHz on all 12 cores!
