RAM Memory Tester Card DDR4 DDR5 2 In 1 Slot Diagnostic Analyzer for Laptop with LED Light Red

Feature: 1. APPLICABLE SCENARIO: Suitable for DDR5, 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 2. POWER SUPPLY: This product 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 3. MAIN FUNCTIONS: This memory tester to test various faults caused by hardware open circuits and short circuits in memory, addressing issues such as poor graphics memory performance 4. LED LIGHT: The product 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 to support fast charging. 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, indicates that there is no open circuit or short circuit fault in the data line circuit of the memory module 5. 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 memory module, the poor performance of the graphics memory should be considered, and alternative methods or corresponding testing software should be used to find the faulty graphics memory Specification: Item Type: RAM Memory Tester Card Material: PCB Battery: 1 x Battery CR2032(not included) Features: 1.
