Feature: FOR REPAIRING MOTHERBOARD FAILURES: This DDR5 desktop mainboard test card applied to repair motherboard failures such as no boot, no display, or no memory reading, very useful. CONVENIENT TO USE: Due to different motherboard designs, some lights may not light up. Can use the same motherboard to diagnose faults. Powered by 1pc button battery, the lightweight and compact desktop mainboard test card is easy to install. SIMPLE TO USE: Supports for and for motherboards with DDR5 interface, and no external power supply required.
