Archive of materials for older Nvidia graphics cards from the GTX 500 to GTX 900 series, about 143 MB in RAR format. The name does not say whether it holds schematics, boardviews or BIOS images, so check the contents after extracting. Such references help with tracing core and memory power stages, identifying failed VRM parts or reprogramming a card's BIOS chip. Match each file to the PCB number and memory configuration of the card, and back up the original BIOS before writing any image.
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 @videocard_notebook_resistance. Enginerys does not host this file.
