Archive about Radeon Vega graphics cards with HBM memory, around 7.35 MB in RAR format. The name does not state whether it holds schematics, boardviews, BIOS images or notes, so check the contents after extracting. Vega cards place HBM stacks on the GPU package, so power rails for the core and memory and their VRM controllers are the usual focus of repair. Any reference material should be matched to the exact card model and PCB revision before measurements are relied upon.
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.
