Boardview for an ASUS GTX650 graphics card in the 1 GB GDDR5 configuration, as indicated by the 1GD5 token. The .fz layout can be opened in FlexBV and similar boardview programs, giving part locations, pin names and net tracing for the whole PCB. Repair work typically involves following the PCIe 12 V and slot power paths, checking GPU core and memory phases for shorts, and identifying unmarked components. Make sure the board revision on the card matches this layout, since ASUS reworked PCBs within a product line.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @cyberlanelectonik. Enginerys does not host this file.
