ASUS GTX560 DirectCU II TOP boardview, the name noting a dual-slot (2DI) design with 1 GB of GDDR5 memory. Saved as .fz, it is read by boardview viewers such as FlexBV, which display both PCB sides with searchable designators and nets. Handy for diagnosing a dead card: locate the VRM controller, trace the core and memory rails, find feedback resistors and confirm continuity to test pads. TOP models are factory overclocked, so check that the card in hand is this exact variant and PCB revision.
