Small colour spots on the top of the ram

[STR_0311]

Hi, I just got myself a GSKILL 8GB DDR4 2133Mhz ram and I found various colour spots on the top of the ram. I'm not sure whats that or thats how its supposed to be. Can anyone confirm me if there's nothing to be worried about or any method that can verify the ram is good? Memtest86? Thank you. Attached the photo below.

Minor imperfections in the PCB. I doubt it's anything to be worried about. You can test with MesTest86 to be sure.

They may be Optical alignment marks for the automated assembly process in manufacturing.

Okay, sure, thank you very much.

Means its just a marking? Nothing to be worried about?

I hadn't even considered this, but this is more likely the reason than what I said. It means it's markings used to line them up in front of cameras during assembly and manufacturing and is simply pasted on there, having no affect on what happens inside the DIMM.

Got it. Feeling relieved.
