Playing Monster Hunter: Wilds with a DeepCool AK620, but my frequencies are swinging too much. Time to push?

I tried simply cranking the multiplier at first and got an instant Blue Screen in OCCT. I realized I couldn't just throw voltage at the problem. I went into BIOS $ ightarrow$ Advanced Voltage Settings, set a core voltage offset of -0.05V, and locked the LLC droop to Level 3. In my DDR5 memory tests, the frequency swing narrowed from ±172MHz down to ±139MHz, effectively clawing back about 146MHz - 216MHz of stable clock. I then exported this config as a backup profile in the BIOS. While Cinebench R23 showed my final landing zone was 64fps - 69fps, locking the voltage bumped my idle power draw by about 5W - 10W. This means my fans are a bit noisier when I'm just sitting on the desktop, but it's a small price to pay for a locked 60fps+ experience.
