HMT-TT04 Desktop DDR4/DDR5 2-in-1 RAM Tester (Dual Power Supply)
The only tester you need for both DDR4 and DDR5 — diagnose memory faults in seconds, no PC required.
About This Product
The HMT-TT04 is a professional-grade, standalone memory diagnostic tool that supports both desktop DDR4 (288-pin DIMM) and DDR5 (288-pin UDIMM) memory modules on a single board. Powered by a dual power system (built-in coin cell battery + Type-C USB), it gives repair technicians maximum flexibility on the workbench or in the field. Each pin is mapped to a dedicated LED indicator, making fault location instant and precise — no software, no computer, no guesswork.
Key Features
2-in-1 DDR4 & DDR5 Support: One tester covers both memory generations — test DDR4 DIMM and DDR5 UDIMM modules without switching tools
Full LED Pin Mapping: Every pin has a dedicated LED indicator. Lit = healthy connection; unlit = fault detected. Instantly locate the exact defective pin
Dual Power Supply: Powered by built-in coin cell battery or via Type-C USB cable (included free) — no power shortage on the bench
Detects All Common Faults: PCB defects, damaged resistor networks, open circuits, short circuits, impedance damage, signal integrity issues, and general performance failures
No PC or Software Required: Fully standalone operation — insert the module, press the button, read the LEDs
Clear Pin Labeling: All pins are individually numbered on the PCB for fast cross-referencing during diagnosis
Free Type-C Cable Included: Ready to use out of the box
Power Options: Built-in coin cell battery / Type-C USB (5V)
Interface: Type-C port (left side)
