My 9800X3D has weird response spikes in crowded GTA V RP areas. Should I lock the core clock?

Exploring Los Santos with a crowd of players is great until the sudden, jarring frame drops hit. The 9800X3D's boost clock was too aggressive with FiveM's scripts, jumping between 3.2GHz and 4.8GHz, which spiked frame times from 12ms to 38ms. I first tried killing all background apps, but the frequency oscillation persisted—just another dead end. I went into the BIOS, disabled Global C-States, and manually locked the core frequency to 4.2GHz. RTSS showed the frame time variance shrinking from 10-35ms to a tight 13-16ms, making the game feel way more fluid. Disabling C-States bumped my idle temps by 7℃, but I tweaked the fan curve to keep it manageable. CPU temps now sit at 68-75℃, with VRMs at 72-78℃. Monitoring confirms the frequency mode is now locked and stable.
