Hi I really need help. I just bought a i9 9900kf from Amazon and when I look at task manager it only shows that it's using 3 cores and 6 threads when it's supposed to have 8 cores and 16 threads. Does anyone know what is going on? I am starting to think that they gave me a defective/fake cpu but I am not sure. I had an i5 9400f and it was working just fine
