DDR5 Desktop Computer Memory Slot Motherboard Repair Test Tool

DDR5 Desktop Computer Memory Slot Tester Motherboard Repair Test Tool

1. Product Overview:

The DDR5 Test Light Diagnostic Card is a next-generation memory testing tool. It does not require an external power source. By using LED lights, it indicates open or short circuits on data and ground signal lines, helping identify motherboard issues related to memory.

2. Instructions for Use:

1. Install a CR2032 battery into the tester and insert it into the DDR5 memory slot.
   The motherboard does not need to be powered on.
   Press the switch on the tester.

   • If all LEDs light up evenly, the signals are normal.

   • If some LEDs are off or brighter/dimmer than others, it indicates a pin issue.

2. If an LED is off, this may indicate an open circuit.

   • Use the LED label to identify the corresponding pin,

   • Then trace the pin to find the signal path.

3. If an LED is unusually bright, this may indicate a short circuit.

   • Again, use the LED label to identify the corresponding pin and signal path.

3. Notes:

1. Motherboard designs may vary slightly, and memory pin signal names might differ.
   However, pin positions remain the same, so this DDR5 tester uses pin numbers instead of signal names.
   This helps users easily identify faulty pins.

2. This tester only works with memory installed directly in the CPU slot.
   It does not support memory connected via Millbrook or N/B bridge chips.
