RAM Memory Tester Card Desktop Computer DDR4 Diagnostic Analyzer with LED Light SPD Burning Multifunctional Maintenance

Feature: 1. APPLICABLE SCENARIO: Suitable for testing DDR4 memory modules on desktop computers, for diagnosing PCB malfunctions, component failures, open closed circuits in the graphics memory, and poor graphics memory performance, etc. Additionally, has the function of SPD burning 2. 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 USB 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 3. FAULT DETECTION: The RAM memory tester card is used to detect memory faults in computers. Uses surface mount components and is safe to handle, which is a good choice for repairing desktop and server computers 4. 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 there is no open circuit or short circuit fault in the data line circuit of the memory module 5. 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 hardware test of the memory module, the issue of poor performance of the graphics memory should be considered, and alternative methods or corresponding test software should be used to locate the faulty graphics memory Specification: Item Type: RAM Memory Tester Card Material: PCB Battery: 1 x Cell battery(not included) Features: 1.
