Features: DDR5 memory testing card is suitable for desktop computer DDR5 UDIMM/RDIMM memory. The failures of computer memory mainly due to poor contact of the gold pins, wear and tear of the gold pins, break PCBs, damage to the data line exclusion, open and short circuits in the video memory, and poor memory performances. LED light is used to testing all data lines of the memory, and the normal brightness is regarded as normal. When a hardware fault occurs these data lines, bright or not light is abnormal. If testing light flashes, it means that the gold pins is in poor contact. If there is not light light, it means that the hardware have open circuits failure. Check the wear of the gold pins, whether the exclusion is damaged, and whether the PCB is disconnected. Insert the battery into the battery holder of testing card, or connection the USB C cable , and then insert the memory card to testing.
