Hello, I'm attempting a small CPU overclock. The Stock Wraith Cooler only manages to hit around 70°C under load, so I think I need some extra thermal margin for a modest 200-300MHz boost, particularly since my CPU doesn't increase its speed when things get tough. At the default settings, my BIOS shows a VCore of 1.376V which seems unusually high. When I raise the clock speeds from 3200MHz to 3400MHz it drops to a steady 1.000V, which is confusing. Also, whenever I try to push the CPU further—whether in BIOS or using Ryzen Master—I notice that all the limits for CPU PPT, TDC, and EDC vanish, even showing up in HWinfo.

My main concerns are: what VCore value should I start with? Why does my motherboard suddenly drop the VCore when I increase the frequency by 200MHz? And why are these power limit issues disappearing and how can I resolve them?

I'm using an MSI B450M Pro vdh Max board, a Corsair CX 600M 600W PSU (about five years old now), 16GB DDR4 RAM overclocked to 3000MHz from 2933MHz with timings adjusted from CL18 to CL16 (stable per Memtest), an RX 5600 XT, an NVMe SSD, and an HDD.

Thank you!

I've chosen a base voltage of 1.2 at 3.4 GHz with a maximum temperature of 87.5°C using a Prime 95 test. I'm concerned about EDC, TDC, and PPT values not showing up in Ryzen Master or HWinfo, and I'm looking for advice on possible solutions.
