MSI MS-7B79 boardview covering revision 3.0 of the board, provided in a 1.17 MB ZIP. Once unpacked, it opens in common boardview viewers like OpenBoardView or FlexBV. A technician uses it to find a component quickly by its reference, follow a net across the board, and choose test points when measuring rails or diode-mode readings during short hunting. Check the revision on the PCB reads 3.0 before relying on it, since earlier and later revisions of this model have their own layout files.
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 @cidschematicandboardviewofficial. Enginerys does not host this file.
