The Ryzen random number generator below the base clock decreases over time.
3700x on a MSI B450i, while using cinebench r20, my all-core turbo runs around 3.9GHz. Occasionally I notice cores dropping to 2.8GHz, though I believe the base clock should be 3.6GHz. It seems there might be an unusual behavior—some cores jump back up after a drop. I haven’t changed any BIOS settings except enabling 3200 MHz RAM. Edit: When idle on the desktop with nothing running, voltage stays between 0.9 and 1.0V but the clock stays at 3.6GHz.
Scores for 3700x stock typically range between 4700 and 4800, which means you're in a safe zone. You've experienced lower readings before, especially with cooler models. Ryzen processors often reduce clock speed to conserve power, which could explain this trend. The discrepancy might come from different data sources—HWMonitor shows lower frequencies in some columns, while AIDA64's stress test doesn't reflect it. If the slowdown is brief and not ongoing, it's likely nothing significant to worry about. Your temperatures are stable (around 70°C under load), and no BIOS settings have been altered.
