Why does Genshin Impact crash in Sumeru City, and should I recalibrate my Gloway DDR5 timing?

I was traversing Sumeru City in Genshin Impact when the frame rate started fluctuating wildly and my memory temperature hit 68℃. I panicked and tried overclocking the Gloway Dragon Warrior DDR5 6400MHz, which immediately caused a Blue Screen of Death. I realized I needed a safer approach. I used GamePP Shader Compilation Queue Manager to clear the shader cache and recalibrate the timing parameters from Auto to Calibrated. AIDA64 monitoring confirmed the read/write latency stabilized at 8.2-9.5ns and the frame rate locked to a stable 60 FPS.
