The cpu was dropped from a height of 10cm on one of its corners ....a very small piece got separated (broken i guess) or chipped from the corner...both green areas and yellow area(??) are chipped...will it still work??
Honestly, I don't know much about them other than they are gold plated to prevent corrosion and enhance the contact with the socket pins. If you're missing a gold plate then it can't make contact and the CPU won't work and could possibly do something to your motherboard.
