Short tutorial on boosting Ryzen 5000 series performance
Hello, previously it was simple to upgrade older CPUs by just adjusting the safe voltage and pushing the clock speed. Now with features like PBO, Curve Optimizer, undervolting, the process is more refined. For safely overclocking your R7 5700X using Ryzen Master, start by setting the desired max safe voltage and increasing the clock speed only when stable. Regarding CO, you can apply it once after a successful OC or use it occasionally for fine-tuning. For safe EDC/TDC limits, check your CPU model and motherboard specs—your R7 5700X with B450 Gaming K4 and GAMMAXX L240 V1 should follow manufacturer guidelines.
Adjust vcore to 1.4v, choose a medium llc or leave it off, and set multiplier to 47 or 48 across all cores. Your allcore reaches 4.7/4.8ghz overclock. Change vcore to 1.25v, keep llc medium or off, and set multiplier between 44-46 on every core. Both options will outperform the stock, especially with multiple cores—no PBO needed, just a straight static overclock.
It's significantly worse than PBO. With my 5900X, a 4.55GHz static OC would give me about 0.25 seconds faster in Y cruncher and drop 100 points in Cinebench compared to PBO. A few APUs might work, but often you'll hit accuracy limits in all tasks while being noticeably slower in games. Try the PBO configuration and enable it. This shifts the performance curve and pushes the CPU to higher frequencies. It can lead to odd crashes during idle, so I usually stick with a safe setting like -10 all cores and avoid changing it again. If you have Ryzen Master enabled, it should handle the settings automatically. Just enter your BIOS changes so you don’t need to run Ryzen Master in the background. The EDC/TDC/PPT limits act strangely—there are no truly unsafe values, but they can overflow beyond a point. You should aim for a benchmark that matches your regular usage (these optimal ranges are based on typical results), adjust the number, and see how it affects your score. Begin with PPT, keep EDC/TDC steady for most tuning, and alternate between them to find the best balance. At the end, I’d slightly lower TDC since it’s the limit after thermal throttling, though this step isn’t necessary since I haven’t seen any issues. The numbers that worked for my 5900X were 188/177/222 (I entered in steps of 11 to save time, going down to individual values is inefficient). With a lower power chip, your limits will be very different. For a starting point, I’d suggest 90/90/120, but you’ll need to tweak it to find what suits you best.
I applied Linpack Xtreme and SuperPi 32M to optimize my 5900X. At a 10GB workload it operates around 4500MHz. Using SuperPi cores brings performance to about 5130 on the four fast cores, with the remaining two handling 4GHz and the rest operating between 4850-4950. R23 paired with PBO achieves 236xx. I employ 240/160/190 settings and my custom curve.
It's not worth it; the situation isn't what it used to be. OC usually doesn't make much sense these days, and undervolting is better now.
