My Vastarmor RX 9070 XT has frequency swings in 4K enhanced mode in Mario emulators, do I need to verify clock stability?

While running high-scale resolution, I noticed these periodic micro-stutters that were super obvious during fast jumps. The RX 9070 XT tends to have unstable clock jumps in low-load emulator environments, with the core bouncing between 1.2GHz and 2.8GHz. I tried enabling 'Game Mode' in Windows, but that just ate up more background resources without helping the frames—a total waste of effort. I eventually went into the Adrenalin software and manually locked the core frequency at 2.4GHz and tweaked the memory to 2600MHz. HWiNFO showed the clock variance shrink from 1.6GHz down to just 100MHz, and the stuttering dropped by about 60%. My idle power draw did go up by 15W after locking the clocks, but I balanced that out by adjusting the fan curve. Core temps are now sitting between 55°C - 62°C. After five long test runs, the frame times have finally leveled out, and the fans are steady at 1400-1600 RPM.
