Introduction to DDR3/4/5UDMM/5RDIMM Memory Strip Light Tester:


The main faults of computer memory modules are poor contact of the gold fingers caused by dirty gold fingers, wear of the gold fingers, PCB breakage, damage to data cable resistance, and open and short circuits in the graphics memory. We have developed 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.


The product uses 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 (CR20323.6V) into the battery holder or use a TYPE-C cable to support fast charging. Insert the memory module that needs to be tested into the slot of the memory tester. If all indicator lights are on and the brightness is consistent, it indicates that there is no open circuit or short circuit fault in the data line circuit of the memory module.


If the indicator light flashes during testing, it indicates poor contact 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 resistance 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.


Note: This product provides dual power supply mode, which can be powered by batteries or by inserting the standard TYPE-C cable into the charging head or power bank to power the product. The standard battery of the product is a rechargeable battery, please do not discard it after the battery is depleted. This product provides charging function for the CR2032 battery (not included in the published product), and can be charged and discharged simultaneously. When charging, the light shows red, and when fully charged, the indicator light turns green.
