Damaged DIMM Contact?

[Goat]

Hi everyone. I was inspecting my new set of DDR4 RAM which just came in and found an odd looking spot on one of the gold contacts. It looks like a dark spot in person and on the images below but can look noticeably more reflective and shiny than the contacts themselves when under light.

 

I have tried cleaning it off using methods like isopropyl alcohol and a white eraser but none of them worked, and I have no idea how it got there or if it was already there from the start.

 

I have no way of testing the DIMMs as I'm waiting for the rest of my parts and my current system is running DDR3.

 

The spot is only present on one of the contacts and the second stick of RAM does not have this. Neither does the spare stick I have lying around so I'm not sure if I should be concerned or not.

 

It's pretty obvious where the spot is in the images below. If you need a point of reference it's right under the sixth chip from the left right above the contacts.

Even if that is damage, it’s too small to actually prevent contact. If it was half the size of the contract point, that would be different.

Use the eraser of a pencil to rub the contacts then wipe with one of those wetwipes (wet napkins/paper towels)....ideally towel dabbed in isopropyl alcohol.

Don't try to "clean" that contact. You can see where the DIMM socket's pins rubbed against it and already made a perfectly fine connection. All you accomplish by trying to remove that spot is possibly lifting the pad, and then it would actually be a problem.
