How do I stop frame rate drops caused by memory frequency fluctuations?

During a tunnel battle, I watched my Gigabyte GeForce RTX 5060 OC Low Profile 8G memory frequency fluctuate between 13000MHz and 14000MHz on GPU-Z. My frame rate plummeted from 90 to 75 FPS, causing severe stuttering. I tried manually locking the frequency via BIOS, but the system restarted immediately, which was incredibly frustrating. I suspected a driver conflict and spent hours troubleshooting. Finally, I used the GamePP Hardware Sensor page to lock the memory frequency at 13500MHz and fine-tuned the voltage to 1.05V. Benchmark tests confirmed the frame rate stabilized at 85 FPS, with memory temperature between 65°C and 70°C per HWiNFO64 and frame time at 11.5-12.2ms.
