Dealing with power delivery spikes on Maxsun MS-Challenger B850M-K
Every time I hit the main square in an RP server, my PC would just hard reboot without warning—a total disaster during key social moments. I found that the Maxsun MS-Challenger B850M-K VRMs were struggling with the high-frequency transient loads from FiveM mods, causing the Vcore to dip by 0.2V. I tried lowering the resolution to ease the load, but the crashes kept happening, which was incredibly frustrating. I eventually went into the BIOS and manually capped PL1 and PL2 to 65W and 80W, then switched to the High Performance power plan in Windows. Under stress tests, the core voltage stayed stable between 1.12-1.20V. My 1% lows dropped to 40 FPS initially, so I had to apply a slight memory overclock compensation to get the fluidity back. VRM temps are running hot at 85-91℃, but the system is stable. After 8 hours of straight gameplay, the crashes are gone.
