How to stop VRM overheating on Biostar B550MH in Metro?
Every time I entered a snowy scene, the game would just vanish and dump me back to the desktop without any warning, which was incredibly stressful. The VRM module on the Biostar B550MH just couldn't handle the Enhanced Edition's load, with temps screaming up to a 105℃ critical limit, triggering the hardware overheat protection. I tried lowering the graphics settings to ease the load, but while temps dropped by 5℃, I was still crashing once an hour—a total waste of time. I ended up rigging a small 4cm fan to blow directly onto the VRMs and manually capped the PL1 power limit to 85W in the BIOS, with PL2 set to 110W. HWInfo confirmed VRM temps plummeted from 105℃ to a manageable 78℃ - 84℃, and the crashes stopped entirely. I did lose about 8 FPS in the minimums due to the power cap, but enabling PBO auto-overclocking managed to claw that performance back. CPU temps stayed between 72℃ - 78℃. After 3 hours of stress testing, it's stable, and the input response feels much more immediate.
