 "title": "On the GC0308 the sensor clock scales frame rate one-for-one, so the OV3660 PLL trap does not apply and raising the pixel clock is exactly what works",
 "symptom": "Published advice for ESP32 cameras says the driver's default PLL leaves the sensor at roughly half speed and that raising the pixel clock alone changes nothing, because internal frame timing follows the system clock. Applied to a GC0308 that advice sends you hunting for PLL registers that do not need touching.",
