I started getting lots of kernal panics today, and random shutdowns/restarts. I noticed i could trigger them by moving around my macbook. I reseated my ram, i noticed one my ram slots was stuck and I can't get my ram back into it. I took off the topcase for a better inspection and found this solid white goo in the ram slot, its almost like epoxy, i have no clue how this happened, to my knowledge before today everything has been working fine for years. The ram isn't stock, i upgraded to it a few years ago when i purchased my laptop.

Apparently apple uses white lithium grease to lube the ram.

Did you do the upgrade by yourself, or did Apple do it for you? I have never seen white grease on my ram, not like that at least.
 
A little coincidence- I picked up an old Core Duo MacBook today. When upgrading the RAM, I too noticed one of the DIMMs had a white goo (a bit like really crappy thermal grease) on it.
 
The white goo I have seen before in Apple Macbooks it's a thermal grease they use.

If it's jammed it must be slightly off center. Not alot you can do apart from wiggling it gently until it moves. I would try and remove it rather than puching it in and then retry. The sockets are pretty tight hence why they use that white goo!

Good luck!

What are we talking about here? :confused:
 
i ended up getting it out, it was a small piece of white plastic, presumably from the case. no clue how it got in there, but it messed up that ram slot. I think the pins got pushed in too much. I might just buy a 2gb ram stick and call it a day but I'm not sure about their compatibility. I have a macbook core duo

Core Duo's don't support 2GB chips - most will not start up with a 2GB chip in either of the slots......
