ciciglow RAM Memory Tester Card, 4 in 1 DDR3 DDR4 DDR5 Server DDR5 Tester with LED Indicator and Dual Power Supply, for Desktop Computer Memory Hardware Testing

["POWER SUPPLY AND CHARGING: The RAM memory tester card offers dual power supply modes, can be powered by the battery or by inserting a standard TYPE C cable into the charging head or power bank. The second is that can be powered by batteries, can be charged and discharged simultaneously. When charging, the indicator light shows red. Once fully charged, the indicator light turns green","FUNCTIONS AND EFFECTS: The 4 in 1 memory tester is used to test various faults caused by hardware open circuits and short circuits in memory, and to solve problems such as poor performance of graphics memory","LED INDICATOR LIGHT: 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, regardless of whether they are particularly bright or not. Install the battery into the battery holder or use a TYPE C cable to support fast charging. Insert the memory stick to be tested into the slot of the memory tester. If all the indicator lights are on and have the same brightness, it indicates that","USING TIPS: If the indicator light flashes during the test, it indicates poor touch with the gold finger. If the indicator light does not light up, it indicates that there is an open circuit fault in the hardware. Check the wear of the gold fingers, whether the resistor is damaged, and whether the PCB circuit is open. Identify the faulty pin according to the digital indication of the indicator light, and then use a multimeter to determine the specific cause of the fault. After passing the","APPLICABLE SCENARIO: Desktop computer RAM memory tester card is applicable to four types of RAM: desktop DDR3 and DDR4, DDR5 and server DDR5"]
