How do I fix clock speed fluctuations on Zotac RTX 5070 Ti?
Whenever I'm sneaking into a castle, the frame rate just tanks from 110 FPS down to 75 FPS without warning—it's a total nightmare for immersion. I noticed the Zotac RTX 5070 Ti's Boost clock was jumping wildly between 2100-2450MHz under dynamic loads, which basically choked the rendering pipeline. I tried toggling 'Prefer Maximum Performance' in the NVIDIA Control Panel, but the frame time spikes stayed stuck between 15-25ms; that software switch did absolutely nothing. I ended up using MSI Afterburner to manually lock the core clock at 2350MHz and bumped the core voltage to 1.05V to keep it from crashing. Checking RTSS, the frame times finally tightened up from a chaotic 8-22ms range to a rock steady 7-11ms. It wasn't a smooth ride, though—the system CTD twice during high-load tests until I added another 0.02V offset. Now, GPU temps sit between 64-70℃ with fans at 1600 RPM. HWInfo confirms the frequency curve is a flat line and frame times are locked at 7-11ms.
