Hello there! Here’s a revised version of your text:

Hello, welcome! I’m starting my first DIY build today. I’m using an MSI MAG B650 Tomahawk with Wi-Fi, a Ryzen 5 9600X, Thermalright Peerless Assassin 140 GTX 1660 Ti (from my old machine, holding off on the 5070 Ti), a 32GB DDR5 Corsair Vengeance 6000 CL36 (2x16GB), and the Seasonic FOCUS GX-850 (2024). After booting into BIOS, I saw some built-in overclocking features like Game Mode and Precision Boost Overdrive. (I’ve already turned on EXPO.) My main question is: should I turn any of these on or adjust other settings in BIOS for overclocking?

Hey there! Welcome to the forums. That setup looks really powerful with the 5070 Ti. For Ryzen 7000/9000 models, we typically turn on PBO and run a -20 to -30 curve optimizer. It’s essentially a controlled undervoltage with a bit of overclocking. On my 7700x I averaged about 15°C lower voltage and saw around 350 MHz boost across all cores. The gains aren’t massive, but it definitely improves overall performance. Check out the video linked for more details. The same principle works for the Ryzen 9000 CPU as well.

CO is optional for temperatures and boosts performance, though it's completely safe when done properly. (The only issues are system instability, minor parts effects, and potential harm during high-stakes ranked matches.) I’m unsure exactly how much gain or loss in MHz/temp I experienced personally, but I’ve noticed slight undervolt just because it works. The 1% lows are okay.

Consider keeping only the CO with negative 20 to -30 and setting the thermal throttle to 85, or adjust the power limit for optimal temperatures at stock speed?

Keep all stock settings for the CPU. Turn on PBO and that's it. For extra help, look up any Ryzen undervolting guide and apply those steps.

Thanks a lot for the help! I tried PBO and CO -20, but I’m seeing about 20 cents less on my CPU. It used to be around 85-87 during PBO alone in Cinebench, now it’s about 67-68 under full load.

Absolutely, -20 means 20 milivolts less per step in MHz/GHz. Each clock speed requires a specific voltage, but the voltage level is now reduced by 20mV, resulting in lower temperatures or improved performance.
