[Led Indicator System] The tester uses bright led lights to monitor all data cables in the memory. any hardware faults are immediately visible through changes in led brightness. simply insert the memory stick into the slot - if all lights illuminate uniformly, your memory module is fault-free. fast charging via type c ensures quick readiness for testing.
[Dual Power Supply Modes] The ram memory tester card offers flexible power options, allowing you to use either a standard type c cable connected to a charging head or power bank, or a button cell battery (not included). the dual power supply ensures uninterrupted testing. during charging, the indicator light glows red, turning green once fully charged, providing clear status updates.
[Fault Diagnosis Made Easy] Flashing indicator lights signal poor contact with gold fingers, while unlit leds indicate open circuit faults. the digital display helps pinpoint faulty pins for further investigation with a multimeter. this tester also checks gold finger wear, resistor damage, and pcb circuit integrity, streamlining your repair process.
[Comprehensive Memory Testing] This 4 in 1 memory tester is designed to diagnose various hardware faults, including open circuits and short circuits in memory modules. it effectively identifies issues causing poor graphics memory performance, making it an essential tool for computer technicians and diy enthusiasts.
[Versatile Compatibility] Perfect for desktop and server maintenance, this tester supports four ram types: desktop ddr3, ddr4, ddr5, and server ddr5 (udmm and rdimm). its surface-mount components ensure safety during operation, making it an indispensable tool for computer repair shops and it professionals working with various memory modules.
