Laptop DDR4/5 Memory Tester Card, SO DDR4/DDR5 Diagnosis Card, PCB Circuit Test Tool for Laptop DDR4/5 Memory Stick

It is used to Identify open circuits, short circuits in memory hardware, addressing issues such as poor graphics memory performance
Computer Memory Failures: The failures of computer memory are mainly due to poor contact of the gold pins, wear and tear of the gold pins, broken PCBs, damage to the data line exclusion, open and short circuits in the video memory, and poor memory performance, etc.
LED Indicators: LED indicators are used to test all data lines of the memory, and the normal brightness is regarded as normal. When a hardware fault occurs in the loop of these data lines, bright or no light is abnormal.
How to See Indicator: If the test indicator flashes, it means that the gold pin is in poor contact. If there is no indicator light, it means that the hardware has an open circuit failure. Check the wear of the gold pin, whether the exclusion is damaged, and whether the PCB is disconnected.
Power choice: You can use battery(Not included in Package, pls prepare it in Advance if needed) into the battery holder of the test card, or connect the type C cable with computer
