Small Excel spreadsheet whose name refers only to GDDR6X, the high-bandwidth graphics memory used on recent high-end video cards. The name gives no card model, memory vendor or part numbers, so the exact contents are unknown until opened. Such tables typically collect memory chip markings, densities and compatible manufacturers, which helps a technician identify or replace VRAM on a graphics card. Open it in Excel or LibreOffice Calc and cross-check any part number against the chip markings and the card's own documentation.
