Fixing power delivery spikes on MSI B450M MORTAR MAX?
Every time I tried to sneak through a crowded map, the game would just vanish to desktop at random intervals, which is incredibly frustrating. The VRM modules on the MSI B450M MORTAR MAX were hitting 88-94℃ under load, causing the CPU core voltage to swing wildly by 0.05-0.12V. My first instinct was to underclock the CPU to 3.6GHz; the crashes stopped, but my FPS tanked from 80 to 55, which was a dealbreaker. Instead, I used a third-party tool to lock the VRM fans at 100% and set a positive CPU voltage offset of +0.025V in the BIOS. In OCCT, the voltage ripple shrank from 0.1V to a stable 0.02V, and I managed 10 hours of crash-free gaming. I had a few boot failures initially until I backed the offset down to 0.015V. VRMs now sit at 72-78℃ and cores at 65-71℃. The system logs are clean, and the input response feels way more tactile now.
