Compressed RAR package of about 839 KB for the Gigabyte GeForce GTX 1650 Super D6 4 GB card, model GV-N1656D6-4GD, revision 2.0. What the archive holds is not stated in the name, so open it with WinRAR or 7-Zip to see whether it contains a boardview, schematic or other service material. Files of this kind help a technician follow VRM and memory power paths and locate faulty parts. Gigabyte often revises boards within one model, so confirm the PCB is marked r2.0 rather than an earlier revision before use.
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.
