Specifications: · Material: PCB · Color: Black · Compatibility: Suitable for all 1151 main boards · Size: 38 x 38 x 3 mm (1.5 x 1.5 x 0.1 inch) · Weight: Approx. 26g How to Use: 1. Insert the test card into the 1151 CPU socket, then press down the CPU cover plate (ensure the motherboard is powered off during this step). Connect a 3V battery to the test lamp row needles; all DMI signal lamps should illuminate. If any lamp remains off, it indicates a short circuit. For further verification, gently adjust the CPU compression bar and use a multimeter. 2. Once initial tests pass, install the CPU and use an oscilloscope to verify voltages, clock signals, and other key parameters, ensuring system integrity. Package Includes: · 1 x Test Card with Indicator · 1 x Test Card without Indicator Additional Notes: - Ensure correct battery polarity when connecting to avoid indicator malfunction. - Replace the 3V battery if indicator lights dim after multiple uses to maintain accurate readings. - Due to specific motherboard characteristics, some signals like CPU power supply voltage may require additional comparison tests or alternative diagnostic methods. This Test Card with Indicator is an essential diagnostic tool for technicians and enthusiasts working with 1151 motherboards, providing an efficient, user-friendly solution for testing and troubleshooting motherboard signal issues with improved accuracy and convenience.
