    I recently bough a 1 gig to update the ram in 2008 imac. I installed it and it would not boot. So I took the original ram out and installed new ram in original ram slot and it booted just fine. Any ideas to what could be wrong with the 2nd slot? Or what I can do to get it to read both sticks ram? They are both 1 gig so it is a match.

    You have not given enough information. We need make, speed, type etc, also specific model of iMac. Hoe many sticks did you have originally, how many sticks did you try to install?

    Three possible reasons: 1. The RAM doesn't work. Quite possible if you bought used RAM from eBay, unlikely if you bought from some reliable source. 2. The RAM is not compatible with the iMac. Hard to say from here. 3. The RAM wasn't installed properly. I have no experience with the iMac, but on a MacBook you had to push the RAM in so hard that it made the fingers hurt.

    It's true...A lot more force is required than you might think. As for compatibility, we don't have enough information to comment.

    I just went through this with someone trying to upgrade their mbp. He had tried several times, so didn't think it was underseating, but then I watched him do it and could tell it wasn't going in all the way. You have to really shove that stick in, it feels like you're breaking it.

    Processor Name: Intel Core Duo
    Processor Speed: 1.83 GHz
    Number of Processors: 1
    Total Number of Cores: 2
    L2 Cache: 2 MB

    SMC Version (system): 1.1f5
    Hardware UUID: 00000000-0000-1000-8000-0016CB858C01

    Here are the specs. And I did 'seat' the ram I'm just wondering if the slot is bad or could there be some dirt so it won't connect. Right now I am using the new ram so I purchased the correct ram for the machine and it was new. I've installed tons of ram in many macs and never had this problem. Also i have looked this model up on Mactracker and it states will handle the latest osx. It won't let me instal lion anyone else have the same trouble?

    Could be dirt or other contamination. I've seen that, too.
