Fixing power delivery issues on Maxsun MS-Challenger B850M?
I can't believe that turning on Ray Tracing dropped me to 30 FPS—it's a complete waste of RTX tech. It turns out the power delivery on the Maxsun MS-Challenger B850M was seeing voltage drops of 0.12V under load, which triggered the CPU's protective downclocking. I first tried disabling all power-saving options in the BIOS, but that just sent the VRM temps skyrocketing to 105℃, which was basically just cooking my motherboard. I eventually changed the long-term power limit from Auto to 65W and cranked my front case fans to 1400 RPM for better airflow. In my tests, the core frequency finally stayed locked at 4.1GHz. I spent hours messing with GPU drivers thinking that was the problem, which was a frustrating misdiagnosis. VRM temps are now stable at 75-82℃. I've backed up my BIOS voltage and power settings, and the fans are steady at 1300-1500RPM.
