How to Use
Insert the battery (not included), or use a TYPE C cable for 5V power supply, support fast charging. Insert the memory module to be tested into the slot of the memory tester. If all indicator lights are on and at the same brightness, it indicates that the memory module data line circuit is not open or short circuited. If the indicator lights are flashing during testing, it indicates poor contact with the golden finger. If any indicator light is not on, it suggests a hardware open circuit fault. In this Box/Cover, check the wear condition of the golden finger, identify the faulty pin according to the pin number indicated by the lights, and use a multimeter to determine the specific cause of the fault: whether the resistor is damaged, whether the PCB circuit is open, etc. After passing the hardware test of the memory module, consider the possibility of poor video memory performance. Use alternative methods or appropriate testing software to identify the faulty video memory.
