can you tell me if the radeon hd 6690 graphic card in compatable with ga-ma770-ud3 mother board as when i fitted it i got a high pitch noise coming from the computor and when i put my old card back in it worked ok thank you for your help
I dont see any reason why its not. That board has a PCI x16 slot which the gpu fits into. Unless its the card itself making the noise it should be fine.
