My Soyo SY-King Dragon H510M is causing texture flickering during high-speed swinging in Spider-Man 2, what gives?

The textures on the Manhattan buildings were flickering like crazy, creating this awful visual tearing whenever I picked up speed. Looking at the logs, the PCIe lanes on my Soyo SY-King Dragon H510M were hitting latency spikes of 115-140ns during high-frequency data requests. I tried forcing 'Prefer Maximum Performance' in the NVIDIA control panel, but the flickering kept coming back every 10-15 minutes, which was a total nightmare. I decided to flash the BIOS to the latest version and manually locked the PCIe link speed to Gen3 instead of leaving it on Auto. In the GPU-Z bandwidth test, my read speeds climbed from 11.8GB/s to 14.5GB/s, and the flickering vanished instantly. I actually bricked the boot process once during the flash because of a voltage dip, but a CMOS clear got me back in. The chipset is now idling at 45-51℃ and MemTest86 confirmed zero errors over three passes. My memory is holding steady at 45-51℃.
