Boardview for an RTX 3060 Ti graphics card, in BDV format according to the name, packed in a 1.09 MB RAR. No PCB number or card vendor is given, so the layout may only match certain RTX 3060 Ti boards. A boardview viewer such as OpenBoardView or FlexBV shows the placement of VRM phases, memory, controllers and test points, helping trace a shorted rail or a missing core voltage. Compare the PCB number printed on your card with the layout before relying on it.
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 @pkbiosbdv. Enginerys does not host this file.
