I have new installed 8 gb ram in to my 2010 imac i3.

It kernel panic when booted, but worked when I start it in safe mode.

It also shows as 12 GB ram. ( 4 Gb original and 8 gb new. )

How can I make it work in normal mode ?

  • did you verify that you bought the right RAM for your machine? (just do a search for "what RAM for my mac")

  • I did, what i wonder is it is working in safe mode, but not in normal mode.

  • yea, as long as you know it's the right kind it's highly likely it's just a bad RAM stick. let them know and they'll swap it out pretty quickly for you I'd bet.

First thing is to simply remove and reseat the chips. Restart, zapping the P-RAM as you go - might be surprised to find it's all okay.

Safe mode does not utilize the full 12 gig.

I would do the RAM test to make sure it is working.

Here is a link to a very good way to do that.
