The recommended basic PBO configuration for the AMD Ryzen 9 9950X is typically set to 2.0.
Hello everyone, I upgraded my processor from the 7900X3D to the 9950X. I mainly use the computer for design and artwork rather than gaming. I usually play scenario-based games at 4K resolution, which puts more strain on the GPU. I switched to the plain X series, thinking I didn’t need the 3D Cache as much. What are some simple PBO adjustments you can suggest for this 9950X? Which one should I use? By default, I enabled PBO Enhancement and set the temperature limit to 90°C. Do you have any other suggestions? My motherboard is an Asus X670E CH Hero. Thank you for your help.
Maintain temperature around 95, otherwise performance drops significantly. Adjust PBO curve offset to -30 for improved temps and speed. You can push the CPU further and explore advanced settings, but for maximum gains, aim for quick configuration changes with just a few clicks.
For the 9950X you don’t have to force PBO excessively; it already provides strong gains. Begin with PBO Enhancement as before and keep scalar on Auto. Adjust PPT/TDC/EDC limits slightly higher if cooling is effective, but monitor temperatures closely. Using Curve Optimizer with 10 to -20 per core generally balances performance and efficiency well, especially if stable. A temperature limit near 90°C works, or you can aim for 85°C for a quieter run.
You configured it according to your instructions. It looks quite stable now. The temperature cap is set at 90°C, which should be fine. I assume the processor isn’t running continuously, so there’s no risk of overheating. Thanks a lot!
The 90C rating meets specifications for that CPU, making it acceptable as long as it isn’t running at full capacity continuously. For slightly more headroom and reduced noise, setting the limit to 85C is perfectly acceptable.
I activated PBO and adjusted the temperature cap to 90°C. The performance boost is noticeable without any issues. I’m achieving excellent results. I believe this setting won’t cause trouble for this chipset. I don’t run it continuously under full load; I only engage all cores occasionally during rendering tasks. Outside of that, I rely on it mainly for regular use and gaming. I followed the instructions in the provided link. ASUS PBO ENHANCEMENT GUIDE
Yes, looks good, and then do you see at the bottom of the bios image there, it says curve optimiser, thats where the negative/positive curve offset parameter we were talking about should be, this will limit excess voltage, which the excess ramps up power but doesnt actually provide any performance, it only provides cpu stability (this is very simplified btw) but manufacturers way overshoot the voltage target to make sure its stable. So depending on your cpu, you can dial it back a little from like 130% of the minimum voltage requirement to like 110%, using less power (voltagexcurrent=power) which means less watts used for the same performance, meaning either, more performance for the same temperature, cpu runs cooler for the same performance, or a bit of both, somewhere in between, little bit cooler and a little more performance I did this to my mates computer when he upgraded to a 5700X as an experiment, his multi-core cinebench results rose 12% and the average temps were 1C lower during the run, took a bit to dial in with the stability though, think we ended up on something like -25 or -27, which provided better performance than -30 (which is the max) as it was more stable and wasnt fighting itself to not crash
The PBO Enhancement automatically manages voltages, so I didn’t need to adjust them manually. If I turn off the Enhancement and tweak settings directly in Curve Optimizer, that could work too. I’m considering using NEGATIVE mode with -10% voltage across all cores and capping temperatures at 80–85°C. Running OCCT tests seems like a good starting point.
PBO enhancement stands alone and must function together. The curve optimizer adjusts the preset voltage curves slightly lower than standard, aiming for a 9950X setting that can manage the -30 range without issues, though this isn't a fixed guarantee. The values are arbitrary and not a precise percentage—just a reduction of about 30 notches in the predetermined curves.
