ASUS GTX770 boardview with no model series, memory size or PCB code stated in the name. Its size matches another GTX 770 DirectCU layout, which suggests the same design, though that cannot be confirmed from the name alone. The .fz file opens in FlexBV and similar viewers for tracing nets and locating parts. Use it to inspect the VRM, memory power circuits and inputs when measuring shorts or missing voltages, after checking the board code on your card.
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.
