How to fix CPU throttling on Biostar H310MHD3 in Dragon Age: The Veilguard
During massive magic battles, my FPS would suddenly crater from 50 to 15—the VRM bottleneck on this budget board is honestly pathetic. The Biostar H310MHD3's power stages were screaming at 105 - 112℃, triggering a hard CPU throttle that dropped my clocks from 3.6GHz to a miserable 0.8GHz. I tried limiting the CPU power in software, but that just added 2 minutes to my loading screens and the stuttering stayed—it was a totally useless fix. I eventually went the physical route and rigged a 4cm mini-fan directly onto the VRM heatsinks, while setting the BIOS power management to 'Balanced'. HWInfo showed the VRM temps drop to 75 - 82℃, and the CPU clocks stabilized between 3.2 - 3.5GHz instead of crashing to 0.8GHz. I actually knocked a jumper loose during the fan install and couldn't boot for a second, but a quick manual check fixed it. CPU temps are 68 - 75℃, and while the fan is a bit whiny, it works. Fans are locked at 1200 - 1400 RPM.
