What is your full system spec? include make and model of the psu

h81m-d2v
rx 580 8gb sapphire
antec 550w I dont know more from that
there is no way my cpu throttle my gpu
every thing started since I download a bitcoin miner I guess but I have formated the pc after so I dont think it has a connection
