Stability calibration for Maxsun MS-Challenger B850M-K
Trying to run this game on an entry-level B850M board was a joke; I was crashing every thirty minutes. The VRMs on the Maxsun MS-Challenger B850M-K were hitting 90℃ - 96℃ under load, with voltage ripples as high as 0.14V, which just straight up nuked the CPU cores. I tried dropping the in-game settings to Medium, but other than making the game look ugly, the crashes didn't stop—a complete waste of my time. I finally went into the BIOS and manually capped the CPU power limit (PL1/PL2) at 85W and switched the power plan to Balanced. I ran an AIDA64 FPU stress test and, miraculously, it lasted four hours without a single reboot, with temps staying between 78℃ - 84℃. Before I found this fix, I tried flashing a third-party microcode that bricked the board, and I had to use the CMOS jumper to bring it back from the dead. VRM temps settled at 75℃ - 81℃ with fans screaming at 2100 RPM. I've exported all the crash logs for my records. Data exported.
