We'd like to help, please provide a bit more information about your system. For example, how many displays are you using?
Are you using any third party overclock applications such as MSI Afterburner, or Sapphire Trixxx?
Have you checked the GPU fan is free of dust and spinning correctly?
Hi! And thank you for reply . I managed to change the cooling sistem ( i take it from an old ax 3450 ) . The gpu go high to 75 celcius max and the lowest 35.
And i have only one display , an old ibm monitor , i'm using msi afterburner ( now it's working ) , the driver let me go with overclock as i wanted. I can play witcher 3 only if my gpu core its on 1200 mhz and memory clock at 1350 mhz.
So problems gone .
Thx again for reply.
Have a good day!
