I am in despair. I have done more than 50 flash tests of the graphics card with related BIOS from its database TechPowerUp and I always have GPU Clock 0. If anyone can help me because I think I will give up, I have run out of luck. I do the flash with AMDVBFlash / ATI ATIFlash 2.93 through DOS and I use TechPowerUp GPU-Z for the check. The card is ELSA AMD RX 580 memory support Hynix H5GC8H24AJR gpu Elsemere
