Result : Base clock only (e.g., 3.6 GHz instead of 5.0 GHz). Many games still run full speed (RPCS3 often gets memory-limited before clock-limited) but temps drop 20°C. | Symptom | Fix | |---------|-----| | Temp jumps 15°C when entering menus | Disable “Shader compilation in background” (compiles shaders on every core at once) | | Random 95°C spikes then normal | Set “SPU Cache” to “Precompiled” – avoids on-the-fly LLVM recompiles | | Only one core hits 100°C | That’s the PPU thread. Set “PPU Decoder” to “Recompiler (ASMJIT)” instead of LLVM | The Golden Rule RPCS3 is not a stability test – if your CPU hits 90°C+ but stays under TJmax (usually 100°C), that’s “normal” for this emulator. The real goal is preventing throttling. Use HWiNFO64 to watch for “Core Thermal Throttling” – not raw temperature.
