Small Excel spreadsheet of 12.0 KB whose name refers only to GDDR6X, the graphics memory type used on some modern video cards. No card model, memory vendor or board number is stated, so the exact contents must be checked by opening it in Excel or LibreOffice Calc. Tables like this are commonly used in GPU repair for memory part-number cross-reference, chip marking decoding or channel mapping. Confirm any data against the markings on the actual memory chips and the board before reflashing or replacing memory.
