Hello, I was installing my new Intel I7 8700k and took the CPU back out to check over the pins (nothing wrong) and I noticed that the contact points appeared slightly scratched/ discolored over the entirety of them. The plating itself looks fine and nothing is deeply scratched. I just happened to notice this while looking at it with a flashlight. Is it normal for CPU contacts to get these marking after mounting? Again the "scratching" isn't deep and cannot be picked up with my camera, it is only noticeable when a light is shone onto it. Thanks- Sam
