1、WITH INDICATOR: RAM memory tester offer a dual power mode that can be powered by a battery or by plugging a standard TYPE C cable into a charging head or bank. The second is to provide batteries for power supply; it can be charged and discharged at the same time. When charging, the indicator show red, and when fully charged, the indicator turn green2、APPLICABLE SCENARIO: This RAM memory diagnostic analyzer is used to test various faults caused by hardware open circuits and short circuits in memory, addressing issues such as poor graphics memory performance3、FAST CHARGING: The memory tester 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 light will change, whether they are particularly bright or not. Install the batteryCR2032 3.6Vnot include into the battery holder or use a TYPEC 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, indicate that there is no open circuit or short circuit fault in the data line circuit of the memory module4、USING TIPS: If the indicator light flashes during testing, indicate poor contact with the gold finger. If the indicator light does not light up, indicate 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 memory5、APPLICABLE MODEL: RAM memory diagnostic tester card is suitable for desktop DDR3, DDR4, DDR5UDMM, DDR5RDIMM 4 types, use the patch assembly, do not hurt hands. Fixing desktop and server computers is a good option Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-Minnanxin
