PBO, curve optimizer, AMD CBS
Hello everyone! I've been working on my research about enabling PBO, adjusting the curve optimizer, and finding the best settings for AMD CBS. Since I'm not an expert, I thought it would help to compile a checklist so you can review and guide me. Need to enable PBO in BIOS (should I choose Enable or Advanced?); define PBO limits (PPT, TDC, EDC); Curve Optimizer options: Manual, Negative, -30 for all cores; AMD CBS settings: CPPC should be enabled, prefer disabled, global C-state should be active. Thanks!
Don't understand the advanced setting, just try the basic version. Run CO with -30 and see if the PC starts normally. Launch Cinebench and wait at least 10 minutes. If it runs without crashing during the test, you're good to go. For extra confidence, do a 30-minute run later. This helps confirm stability better. Unless there are specific adjustments needed, stick with the defaults unless you notice issues.
Performing this action will lower the performance of your 5800X3D, I assure you. It could be stable around -30, but mine isn't. It remains stable at -28 for all cores. Don't squander your time. All of my cores and threads can handle the 4550 limit, with 4450 effective. Cinebench is merely a test, and it's nowhere near a true stability evaluation.
It operates at full capacity since every unit handles image rendering, which challenges the stability assessment.
Currently, 8750 is active with a game and additional processes running in the background.
Just select the PBO menu to activate the curve; no further actions needed. Operating a 58X3D is similar to operating a Dell.
