Why does Mass Effect Legendary Edition lag on Biostar B550MX?

I was losing my mind during squad assembly in Mass Effect Legendary Edition, staring at a 2.5-4.1s loading screen that broke my immersion. I tried manually locking the memory to 3600MHz, but it caused two blue screens and made the stutter worse. Turns out, the Biostar B550MX/E PRO needed precision tuning. I used GamePP Memory Controller Load Monitor to stabilize the frequency at 3466MHz, set timings to 16-19-19-38, and nudged the voltage to 1.25V. GamePP Benchmark Verification showed bandwidth utilization jumping from 65-72% to a solid 82-88%. My memory temps settled at 45-52°C and VRM at 58-63°C. The lag is gone, and I finally feel the game running as it should.
