Stabilizing core voltage on Biostar H310MHD3 for Overwatch 2
Whenever I flicked my view during a chaotic team fight, my FPS would tank from 140 to 60 instantly. I checked the logs and found the Biostar H310MHD3's auto-voltage was bouncing between 1.0V and 1.2V during load spikes, causing the clock speed to plummet. I tried 'Ultimate Performance' mode in Windows, but that actually made the voltage swings more erratic. I ended up going into the BIOS Advanced Voltage settings and locking the Vcore at 1.18V with a +0.05V offset. Using a frequency monitor, the CPU finally stayed locked between 3.6-3.8GHz without those jagged drops. My temps spiked to 91℃ at first, which was scary, so I had to aggressively tune the fan curve and drop the voltage slightly to 1.15V. VRM temps are now 65-71℃, and the gameplay is finally smooth. I switched the performance profile to 'Extreme' via the board software.
