Schematic in PDF format for the graphics card coded GV-R55XTOC-4GD, revision 1.0, compressed into a 1.61 MB RAR archive. The GV- prefix is the naming used by Gigabyte for its video cards, and the code indicates a 4 GB version; the NP suffix is not explained by the name. Card schematics are used to trace VRM phases, memory and core power rails, PCIe signals and to identify shorted MOSFETs or capacitors. Open with any PDF viewer, and confirm that the PCB revision on the card matches 1.0 before following component designators.
