4-in-1 DDR3/DDR4/DDR5UDMM/DDR5RDIMM Memory Diagnostic Tester Card Universal RAM Module & Motherboard Slot Analyzer Kit for Desktop and Server Computer Maintenance Repair

Efficient Fault Detection: Equipped with LED indicators, the tester quickly identifies hardware faults like open/short circuits or poor contact in memory modules. Consistent brightness across LEDs confirms functional circuits, while flashing or unlit LEDs pinpoint specific issues, helping users isolate faults without guesswork.
User-Friendly Design: The tool features a patch assembly construction for safe handling, minimizing injury risks during use. Clear numerical indicators help locate faulty pins, and the included USB cable simplifies setup. Its compact size makes it portable for field repairs or lab diagnostics.
Practical Application: Ideal for diagnosing common memory-related problemsgraphics performance drops, boot failures, or system crashesthis tester aids in verifying hardware integrity. By identifying worn gold fingers or PCB circuit breaks, it reduces unnecessary part replacements, saving time and costs in computer maintenance.

Troubleshooting
This product comes with a physical switch to switch between USB and battery power
Please ensure that the switch is in the correct power supply position

1. Press the test switch. If all indicator lights are on and the brightness is consistent, it indicates that the hardware of the memory module is not faulty.

2. If the indicator light flashes, it indicates poor contact between the gold finger. If the indicator light does not light up, it indicates an open circuit fault. Check whether the gold finger is dirty, the troubleshooting is damaged, or the circuit is open. Use a multimeter to find the fault point based on the pin numbers of the indicator light.

3. If one or more indicator lights are particularly bright, it indicates a short circuit fault.
