Small Excel spreadsheet titled GDDR6X, the graphics memory type used on higher-end recent graphics cards. The name gives no further detail, but such a table usually lists memory chip part numbers, capacities, manufacturers or compatible cards for reference during VRAM replacement. It opens in Microsoft Excel, LibreOffice Calc or any spreadsheet program. Check the listed codes against the markings on the actual memory packages, and confirm against the chip datasheet before ordering or swapping chips.
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 @cyberlanelectonik. Enginerys does not host this file.
