Feature:1. Application: Computer DDR5 memory tester is suitable for desktop computer DDR5 R DIMM U DIMM memory test. Premium PCB material provides high stability and ensures long term reliable work.2. Computer Memory Failure: Computer memory failure is mainly due to poor contact and wear of gold pins, PCB damage, data line exclusion damage, video memory open circuit, short circuit, poor memory, etc.3. LED Indicator: DDR5 memory tester with LED indicator for testing all data lines of the memory, normal brightness is considered normal. When there is a hardware failure in the loop of these data lines, bright or not bright is not normal.4. Purpose: To check the wear and tear of the gold pins, to rule out any damage, and whether the PCB is disconnected. If the test indicator flashes, it means the gold pin has poor contact. If no indicator light is on, there is a broken hardware fault.5. Easy To Use: DDR5 memory test card is simple and easy to use, insert the CR2032 battery into the battery holder of the test card, or connect the USB C cable, then insert the memory card for testing.Specification:Item Type: DDR5 Memory TesterMaterial: PCBColor: GreenBattery: 1 x CR2032 Button Battery (Not Included)Power Input: USB CApplication: DDR5 R DIMM U DIMM Memory Test.Package List:1 x DDR5 Memory Tester1 x USB Cable4 x Fixing Mount
