Now, that we’ve established our three main players, let’s tackle them one by one. Striking a balance with your settings and overclocking your Ryzen 5000 From the PBO triangle analogy, this mostly impacts the top vertex – heat. This, combined with Precision Boost Overdrive 2 means that you’re pushing less heat, allowing the CPU to boost clock speeds. Undervolting means that you’re pushing slightly less voltage, which consumes less power and generates less heat. Curve OptimizerĬurve optimizer allows you to undervolt your CPU.
From the PBO triangle analogy, this positively impacts the left and right vertices – SoC power and VRM Current, while negatively impacting the top vertex – heat.
Allowing the CPU to take more power overall allows the CPU to boost to higher clock speeds. EDC is the amount of amperage the CPU is fed, under short bursts (electrically limited). TDC is the amount of amperage the CPU is fed, under sustained load (thermally and electrically limited). PPT is the total power that the CPU can intake. Here, I’m referring to the three major power settings – PPT, TDC and EDC. In short, this is AMD’s inbuilt overclocking capabilities baked into your CPU. PBO extends the maximum threshold for these components, allowing faster clock speeds to be achieved for a longer time. Precision Boost Overdrive (PBO for short) is when you extend the out of the box parameters that dictate performance on a Ryzen CPU – Temperature, SoC (chip) power and VRM Current (power delivery). In order to achieve an actual “overclock” on Ryzen 5000, we’ll need to dive into three major components – PBO2, Curve Optimizer and Power Settings Precision Boost Overdrive 2 The golden trio – PBO2, Power Settings and Curve Optimizer In my case, my 5900x is easily able to go past 5GHz. On the other hand, Ryzen’s boost algorithm is designed to go past the usual clocks and boost as much as possible, given there is enough power coming in and the temperatures are in check. If you set a max overclock of say 4.6 GHz, you won’t be able to go over 4.6 GHz in common tasks, which will slow them down. These are the kind of workloads that you go through every day, which are the most important. Why?īy turning on a fixed max boost clock, you will be losing the higher boost clocks achieved when doing lightly threaded workloads (unless you manage to overclock to a fixed 5Ghz.if you do that, please write a guide for us!). You can do it, and you will get a nice score in Cinebench, but you’ll lose everyday performance. Traditional overclocking involved going into the BIOS, typing a nice voltage and a reasonable clock speed and you are done.
Ryzen 5000 – Traditional overclocking is dead The following should similarly work for Ryzen 3000 series, but you will not have access to the Curve Optimizer. The following guide should work for the following CPUs: Following this guide WILL net you a performance gain maybe not the BEST performance gain but a measurable one. Having said that, even if other approaches may be better, they will be slightly better, maybe 1-3% better, within margin of error.
This is not an ultimate overclocking guide and some people might (and already did) not agree with the values and flow of this guide. Please treat this guide as a beginner starting guide – you’ll need to spend a lot of time tweaking, especially on the curve optimizer. Let’s discuss the basics for overclocking on Ryzen 5000.

Ever since I have written my experience using Precision Boost Overdrive 2 and Curve optimizer in my last blog post, I have been asked several questions on how to overclock your Ryzen 5000 CPU.
