Solutions for VEGA 8 overclock issues
I read the article and realized it’s likely I adjusted the GPU frequency to 1500mhz without altering any voltage settings. Since I left the voltages at Auto mode, the GPU runs at that frequency while keeping the system voltage unchanged. I’m curious why others modify both the system and GPU voltages. I performed a superposition benchmark and achieved a score of 2287 with a Cº of 45.
Auto voltage has no restrictions. The CPU/IGPU determines its requirements and sends them to the VRM. If it needs 1.6v, it will ask for that, regardless of whether it uses 1.2v or 1.4v actual. That's why people set voltages manually. Lower voltages reduce heat, but there are also safety limits they avoid crossing, such as with OC and other parameters.
Each CPU reacts differently to voltage levels. The values mentioned in the video are just suggestions; you might need a 1.32v CPU or a 1.216v SoC. Following another CPU's settings too closely can cause black screens.
Begin with auto mode, observe the VRM and BIOS configurations for voltage settings at OC/speeds, then adjust manually. Gradually experiment with different voltages to find what works best.
A stable OC process doesn't happen in a single click—it often takes hours or even weeks to fine-tune the optimal configuration.
