DDR5 Laptop RAM Diagnostic Tester

【Multi-Generation RAM Tester】This laptop RAM tester supports DDR3, DDR4, and DDR5 SODIMM slots on a single board, allowing technicians and assemblers to test multiple generations of memory without switching diagnostic tools. 【Visual LED Detection】An array of numbered LEDs on the board immediately reveals open circuits, short circuits, and damaged resistors on the data lines. Consistent brightness indicates clean continuity, while off or dim LEDs locate faulty traces without a multimeter. 【Pin Troubleshooting Guide】Built-in numbered LED indicators make it easy to identify contact faults and worn gold fingers. If an indicator light flashes or remains off, you can instantly pinpoint the exact pin number for targeted repairs at the board level. [Circuit Continuity Analysis] As a dedicated diagnostic board, this analyzer checks the data lines of memory modules under active power. Simply insert the module into the corresponding slot to assess signal integrity, helping to prevent motherboard damage caused by faulty memory modules. [Dual USB/Battery Power Supply] Powered by a standard coin cell battery or the included USB cable, this portable memory tester offers flexibility for use on the workbench or as part of a mobile repair kit. The package includes a test board, a USB cable, and a clear user manual.
