Fixing frequency drops on Gainward RTX 5080 in R6 Siege?
Right as I'm breaching a room, my FPS would dive from 300 to 120. In a competitive game, that's basically a death sentence. The RTX 5080 was peaking at 380-410W, triggering the internal power limit and making the clock bounce between 2.2-2.8 GHz. I tried pushing the power limit to 110% in MSI Afterburner, but my temps shot up to 84℃, which honestly freaked me out. I went back and rebuilt the fan curve—forcing 85% speed at 70℃—and settled the power wall at a balanced 105%. In HWInfo, the clock jitter dropped from 400MHz to just 50MHz. The first time I tried the new curve, the fan ramp-up sounded like a jet engine, but I smoothed out the gradient and it's fine now. Temps are steady at 72-76℃ with fans at 1900-2200 RPM. No more throttling, though my ears are definitely more aware of the GPU now.
