KCD keeps crashing randomly on my 9950X3D in crowded towns due to voltage instability. Do I need to adjust PPT?

Using a top-tier 9950X3D and still crashing every half hour is a complete joke. The 3D V-Cache was hitting 0.08V voltage swings under high-frequency loads, triggering internal CPU parity errors and crashing the whole system. I tried dropping the game settings to Medium, but besides making the game look ugly, the crashes didn't stop—a total waste of time. I eventually hit the BIOS and manually capped the PPT power wall at 170W, switching the power plan from Ultimate Performance to Balanced. In an AIDA64 FPU stress test, the system miraculously ran for four hours without a single reboot, idling at 85-92℃. Before this, I tried flashing a third-party microcode that bricked my boot sequence, and I had to use the CMOS jumper to bring it back to life. Now VRMs are at 82-88℃ with fans at 2400 RPM. I've exported all the crash logs and the system is finally behaving.
