Boardview in CAD format for board V330 with suffix _80, meaning revision 8.0 in MSI-style numbering; no card model appears in the name, though V330 is the MSI PCB associated with GTX 1070 series cards. The file lets a technician locate components, check which nets they belong to and find test points while chasing shorts or dead rails. Open it in FlexBV, BoardViewer or a similar viewer. Verify the V330 code and revision 8.0 printed on the card before using placements.
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 @laptexdna. Enginerys does not host this file.
