In your previous comment, most folks prefer a straightforward fix rather than detailed steps because it takes too long and they’re not familiar with the process. Platforms like this are useful since people can advise you on what you need, but actually having someone present usually means paying for their time. Most pros tend to reset everything—reinstall Windows, set up drivers, etc.—without really understanding what they’re doing. You should identify the problem first, back up your files, and try a clean install. Updating chipset drivers or choosing between PBO2 Tuner or BIOS settings can help, but changing BIOS settings without knowing their purpose often leads to trouble. If you’re experiencing constant stuttering, it might be a GPU issue. You mentioned DOCP—has the DOCP/XMP feature been enabled? The cooler should work well for a 5800x3D as long as it’s running properly. All other specs look okay. Make sure your BIOS is current and disable Auto OC if you have it.
Docp is an XMP profile and it’s active. The GPU has a dual BIOS setup, so switching it might help. Clearing the CMOS usually means removing the battery or pressing the back panel button—details aren’t clear in the manual. When adjusting PBO2 values, focus on the listed parameters to ensure proper configuration.
The ROG Strix B550-F gaming header is positioned at the bottom of the board, specifically in the bottom right corner. The second pin connector is located to the left of the final header on that area. A bridging approach for the battery would be quicker. The back panel button serves solely for BIOS flashback and does not clear CMOS. Under AI Tweaker Precision Boost Overdrive Curve Optimizer, apply Curve Optimizer for all cores; set all core optimizers to Negative, with a Curve Magnitude of 25.
This was listed in the AI tweaker's bios. For the PBO2 Tuner, follow the instructions from my previous post. There are two sections: the program, Curve, and limits. Curve is set to -25 across all cores, while under Limits you’ll find PPT 120, TDC 80, and EDC 110. That’s it. You can also reset the Max boost to 4550 (adjust if you enter 4600). Also, disable any auto OC features in the ASUS BIOS.
Check the OC options carefully. Core performance boost can usually remain enabled even if the frequency stays at 3.4GHz, as it’s often a separate setting.
Turn it off completely. ASUS prefers keeping that feature enabled automatically, but it’s actually not useful and may lead to problems. The PBO2 Tuner should display on the second page if it’s restricted to 3.4 ghz, and after performing a clear CMOS reset, we should be able to identify the cause.
Thank you for the suggestion. I’ll give it a try tomorrow. If I have any questions, feel free to reach out via this forum—just like replying to an old message.
I followed your instructions to reset the CMOS using a screwdriver as a bridge, which restored the BIOS settings. I turned off Core Performance Boost and checked the PBO2 tuner; it indicated a maximum boost of 4,550 MHz. However, reviewing HWInfo and the Task Manager during heavy usage showed my CPU never exceeded 3.34 GHz. Then I re-enabled Core Performance Boost in BIOS, and it reached around 4.4 GHz or slightly higher. I also set a temperature cap at 85°C instead of 95°C because I don’t want overheating issues. After these changes, I tested the two games I usually play, and the stuttering was nearly eliminated—98% gone. I plan to test other games I know always caused stuttering, and then share the results to confirm if this resolves the problem. I’m not convinced my GPU is the issue since a different one worked before, but it still overheated. I’m uncertain about the exact settings you mentioned, but they seem to improve stability.
