Solving voltage crashes on Maxsun MS-Terminator B850M in CP2077
Driving through Night City at high speeds and having the PC just reboot without warning is enough to make me lose faith in new platform boards. The Maxsun MS-Terminator B850M had a 0.09V voltage drop under transient loads at default settings, which triggered the CPU's internal protection. I first tried disabling all virtualization features in Windows, but that didn't stop the crashes and just broke some of my background apps—a total waste of time. I went into the BIOS and manually set the core voltage offset to +0.06V and added a small fan to the VRM heatsinks. In Prime95, I ran it for 8 hours straight with zero errors, and the reboots stopped completely. I actually tried +0.1V first, but temps hit 98℃ and triggered thermal throttling, so +0.06V is the actual sweet spot. CPU temps are stable at 78-85℃ with fans at 2200 RPM. Exported the profile to a backup; it's finally stable, though the VRM still runs a bit hot.
