Contact issue with the DIMM module?
Contact issue with the DIMM module?
Hi everyone. I checked my fresh DDR4 RAM and noticed an unusual mark on one of the gold contacts. It appears as a dark area both visually and in the photos, but seems more reflective and shiny than the rest when exposed to light. I've attempted cleaning it with isopropyl alcohol and a white eraser, but nothing resolved the issue. I'm unsure if it was present from the beginning or if it formed during handling. Since my system still runs DDR3, I can't test the DIMMs yet. The mark is only on one contact, while the other stick doesn’t have it, and the spare I have isn’t affected either. I’m not sure how serious this is unless I see more confirmation in the images. For reference, it’s located just below the sixth chip on the left side above the contacts.
It might still cause issues, but the impact is minimal and won’t stop contact. If it were double the contract size, things would change.
Use the eraser of a pencil to rub the contacts, then clean with a wet wipe—preferably one soaked in isopropyl alcohol.
