APPLICABLE SCENARIO: Suitable for DDR4 memory maintenance tester, can easily solve the various failures of memory hardware, the use of light tube indication, instead of the traditional multimeter manual measurement method, according to the LED brightness indicator easily find the fault point, so that the computer novice can also become the top memory maintenance expert
POWER SUPPLY: This RAM memory tester card provide dual power supply mode, which can be powered by batteries(not included) or by inserting the standard TYPE C cable into the charger plug or power bank to power the product. Batteries(not included) are available for power supply, and can be charged and discharged simultaneously. When charging, the light show red, and when fully charged, the indicator light turn green
MAIN FUNCTIONS: Computer memory failures are mainly caused by poor contact of gold pins, wear of gold pins, damage to PCB boards, damage to data cable power strips, open or short circuits in video memory, and poor memory performance. The memory tester is a good choice for repairing desktop and server computers
WITH LED LIGHT: The DDR4 RAM memory tester card use LED lights to test all data cables in the memory. When hardware faults occur in these data cable circuits, the brightness of the LED indicator lights will change, whether they are particularly bright or not. Install the battery(not include) into the battery holder or use a TYPE C cable powered. Insert the memory module that need to be tested into the slot of the memory tester. If all indicator lights are on and the brightness is consistent,
TESTING TIPS: If the indicator light flashes during testing, it indicates poor touch with the gold finger. If the indicator light does not light up, it indicates an open circuit fault in the hardware. Check the wear of the gold finger, whether the abrasion is damaged, and whether the PCB circuit is open. Identify the faulty pin based on the numerical indication of the indicator light, and then use a multimeter to identify the specific cause of the fault. After passing the hardware test of the
