RAM Upgrade:System won’t Boot

Hi:

I’ve been attempting to successfully upgrade my ram from 8 GB to 16 GB, without success. What happens is that I will receive the one bell sound, indicating it’s not recognizing the RAM with the one flash.

I’ve tried the hold the power button down + power button + left shift/option + control for 10 seconds each with the laptop connected to and not connected to a power source. The battery cord does light up, if that’s relevant.

I’ve tried installing one stick of RAM at a time - but it makes no difference.

My old RAM does allow the system to boot up and work as normal, THANK GOD.

I am wondering whether dampness could be a factor bc while the RAM sticks were sealed, the box arrived fairly damp, including the interior box.

Any advice is welcomed. I’ve combed this site and YouTube for other solutions and can’t seem to find anything that is workable. I really want to avoid having to go to Apple bc I believe there’s an issue with the RAM (Note: yes my system is capable of being upgraded to 16 GB, I checked)

Are you sure you have the correct SO-DIMMs. I often encounter people try using the wrong ones.

You could use a fresh pink pencil eraser (still soft) to wipe the contact surfaces to remove any oxidation. Also make sure they are full seated.

I don’t think your issue is simple air moisture, but if gotten wet you could have corrosion damage but that would be liquid damage not vapor.

Thanks for responding.

RE SO-DIMMS: I believe so. I used the same ones as my current 2x 4 sticks. I trust that if I wasn’t doing it correctly with the current sticks, they wouldn’t allow for the system to boot up and run.

I trusted that the one beep means no RAM, so I’m not sure what I’m doing wrong if I’m following the same steps for my current RAM and the system boots like normal?
