Video BIOS for a Sapphire Radeon HD3650 PCI-E card with 512MB of GDDR2 memory, packed in a small RAR archive. The number in brackets, 7251000, most likely encodes default core and memory clocks, so compare it with the label or a GPU-Z readout before use. Technicians use such an image to recover a card after a failed flash or corrupted ROM, writing it with ATIFlash or directly to the SPI EEPROM with a programmer. Always save the original ROM first and confirm the memory type and size match your card.
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 @biosarchive. Enginerys does not host this file.
