<p>Applicable Scene: SO DDR4\/DDR5 memory test card is suitable for Laptop computer DDR4\/DDR5 memory.</p> <p>Computer Memory Failures: The failures of computer memory are mainly due to poor contact of the gold pins, wear and tear of the gold pins, broken PCBs, damage to the data line exclusion, open and short circuits in the video memory, and poor memory performance, etc.</p> <p>LED Indicators: LED indicators are used to test all data lines of the memory, and the normal brightness is regarded as normal. When a hardware fault occurs in the loop of these data lines, bright or no light is abnormal.</p> <p>Uses: If the test indicator flashes, it means that the gold pin is in poor contact. If there is no indicator light, it means that the hardware has an open circuit failure. Check the wear of the gold pin, whether the exclusion is damaged, and whether the PCB is disconnected.</p> <p>Easy To Use: Insert the CR2032 battery into the battery holder of the test card, or connect the type C cable , and then insert the memory card to test.</p> <p>Due to different batches, the printed words on the product be different, which does not affect use.</p> <p>Name:DDR4\/5 Memory Tester</p> <p>Type:Hard Drive Adapters</p> <p>Application:Applicable to laptop DDR4\/DDR5 memory</p> <p>Colour:Green</p> <p>Material:PCB</p> <p>Package Contents:</p> <p>1 * SO DDR4\/5 Memory Tester</p> <p>1 * Type C cable</p> <p>4 * PCB Spacer</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
