yes I checked on newegg and compared the ram to the old before putting it in and it fits but the mac wont boot
Try running the machine using just one stick. If it works, swap the sticks- if it doesn't, there is a high chance that you received a faulty module.
did you put the battery back in ?
Even if you think u did it right make sure its not loose or put in the wrong way. Gluck
I would make sure the RAM is seated correctly. Take it out and put it back in. If still no go...try resetting the PRAM and if still no go you may indeed have faulty RAM. Try your old RAM, if that works try each stick individually as said above until you find the stick that is crapped, send it back for a replacement.
Good Luck.

k it works with either the two gig or both others but I can't use both, how do I force it to work cause someone on here said it would
Hmmm, what is your max supported config ?
2 or 3 gb ? and in what combination?
If max is 2 and it has to be 1gb each, your 2gb won't fly.

Wait. I'm lost. Not because of that.
Alright Im back on my Mac but I havent sealed up the L-Plate yet so I need to make this quick.
My MacBook came with 1GB (2x512MB) sticks, I ordered a 2GB stick (single stick), and asked this:

But I failed to catch the 2nd persons reply. But what I'm confused about is his statement:

But mines does boot with a 2GB stick (right now) and people said they've been able it get 4GB with 2x2GB sticks.
You really need to push the RAM in right. If you press really, really hard, then you still have two millimetres to go. Typical sign for a MacBook is that the L-shaped bit of metal around the battery is a bit difficult to get in because the RAM isn't pressed in deep enough.
So if I got this correct, a MB Core Duo WONT be able to support 2x2GB sticks but can support 1x2GB sticks, right?
I don't know.
All the material I have looked at simply lists 2GB as the Max. And it's likely a hard-coded limit, meaning no matter how many sticks you cram in there, 2GB is the max.
If your single 2GB DIMM works stick with it. However, I would be worried that you'd get unexpected results with that DIMM.

Well, we'll see i guess, thanks for the info. Time to seal my MacBook back up.
Next stop: 250GB Hard Drive.

It seems like the quote you posted from a previous thread clearly stated that you should not buy a 2GB stick for your core duo machine.
You should check if there is a return policy on the RAM. If not, try to sell it on here and buy yourself 2 1GB sticks. Stick those babies in there and enjoy your 2GB of worry-free matched RAM.
