Have you stress tested the card?

maybe its just defective.

does it work with the original bios?

With original bios works fine on Windows 10
Heaven benchmark tool tested works fine on stress test.

saving original bios with atiwinflash shows 256KB,while GPU-Z save file was only 128KB,several version of AtiWinFlash has 256KB, why its showing difference in value.
