Repair shop discovers near-perfect fake RTX 4090 with laser-etched VRAM and GPU core

Northwest Repair uncovered a highly realistic fake Asus ROG Strix RTX 4090 after a no-detect failure report.

Microscope inspection showed the memory chips and GPU core had been altered and re-marked to imitate genuine parts.

The counterfeit was so convincing it closely matched real high-end NVIDIA hardware, including laser-etched-style markings.

The case underscores how sophisticated GPU fraud has become and why buyers and repair shops need stronger verification.
