I bought a second hand AMD A10-9700E processor. Couple of pins are covered in grey coat. This is not my first AMD AM4 processor (i have also ryz 5 3800x and ryz 5 2600) and i have never seen pins like this before. First i thought this is a thermal paste, but it is not. It is very regular and looks like factory. Could you help me and explain if this is normal and it is leaving factory like this? I attach photos to show what I mean.
