4 in 1 RAM Memory Tester Card for Desktop DDR3 DDR4 DDR5 and Server DDR5 with Dual Power Type C and Battery LED Fault Indicato

Features
1.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
2.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
3.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
4.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
5.APPLICABLE SCENARIO: Desktop computer RAM memory tester card is

• 【Flexible and Convenient】: This memory tester offers two reliable power input modes for ease of use. It can be easily powered by the built-in coin cell battery or by connecting a standard Type-C cable to a charging adapter or power bank. The intelligent charging system features clear indicator lights: red during charging and seamlessly switching to green when fully charged, ensuring you are always aware of the power status
• 【Reliable Diagnostic Solution】: This memory tester is a comprehensive all in one tool, an ideal solution for identifying various hardware faults. It can accurately diagnose faults caused by open and short circuits in computer memory modules. Beyond basic connectivity issues, it helps you troubleshoot deeper performance problems, such as poor video memory performance, making it an essential tool for routine checks and complex repairs
• 【Intuitive LED Indicator Display】: This tester uses a clear array of LED indicators for intuitive testing of each data line in the memory module. Simply insert the memory module into the designated slot. Consistent brightness of all LED indicators indicates no open or short circuits. Any changes in LED brightness or behavior provide immediate visual cues for potential hardware faults, allowing for quick and accurate initial assessment without complex software
• 【Detailed Fault Isolation Guide】: Guided troubleshooting from fault detection to precise fault identification. Flashing indicator lights indicate connection problems, such as poor contact of the gold fingers; no light indicates an open circuit. Each indicator light is labeled with a number to help you pinpoint the faulty pin. Our guide will direct you to check for worn gold fingers, damaged resistors, or broken PCB traces, and recommends using a multimeter for final verification, simplifying
• 【Universal, Compatible Design】: This tester is designed for maximum usability, supporting four generations of mainstream memory technologies, compatible with desktop DDR3, DDR4, and the latest DDR5 memory modules, as well as server-grade DDR5 RDIMM memory. Manufactured with surface-mount components on a durable PCB, it is a reliable and safe choice for IT professionals, technicians, and PC enthusiasts maintaining or repairing a wide range of desktop and server computers
