GoKawiilFake RTX 4090 with counterfeit GPU die sold as repair project for $350
A Russian repair specialist known as VIK-off examined an RTX 4090 bought as a bare PCB for about 30,000 rubles ($350) and discovered it contained a fake GPU die soldered on via BGA along with counterfeit memory chips mimicking GDDR6X markings. Closer inspection revealed the die's contact area didn't match a real processor and the solder mask degraded during cleaning, while the memory chips were actually GDDR6 rather than GDDR6X, with VIK-off suggesting the board may actually be a repurposed RTX 3090 Ti PCB.
